With some duplex printers, printing might complete successfully, although errors might occur. In addition, some features (such as the printer reporting low ink levels) might not function since two-way communication is not supported. Introducing Your Storage System - 10 Serial ATA 4-Drive NAS User Guide Getting Started Getting started with your storage system involves the following general steps: 1. Install your storage system. This process involves installing both the hardware and software components of your storage system and specifying the initial configuration. For step-by-step instructions for this process, see "Installing Your Storage System". 2. After installation is complete and the storage system restarts, start the Web User Interface and log in. For more information about this step, see "Accessing the Web User Interface" on page 24. 3. Add users. If you want to control access to the shared folders, or if the users in your network use Linux or Macs that don't use OS X, you must create a list of users. For more information about this step, see "Adding Users" on page 30. 4. Create shared folders. By default, the storage system includes a shared folder named public, which all Windows and Mac OS X users can access. However, you might want to create other shared folders as well. For example, in an office environment, you might want to create a shared folder for company policies that everyone can view, and separate folders for confidential business documents that only selected individuals can view or change. In a home environment, you might want to set up separate folders for different types of files, like photos, videos, or music. For more information about this step, see "Creating Shared Folders" on page 33. 5. Access the shared folders. For information about this step, see "Accessing Shared Folders" on page 37. 6. Protect your computer hard disks. This process involves installing DiskSafe Express on each computer that you want to protect and specifying which hard disks or partitions to back up and how often backups should occur. For more information about this step, see "Protecting Local Disks," beginning on page 77. Installing Your Storage System 1. Determine your Configuration. Before you set up your system, you need to decide which configuration you will use. For configuration Getting Started - 11 Serial ATA 4-Drive NAS User Guide considerations, see "Step One: Determine Your Configuration" on page 12. 2. Set up your storage system. This involves installing the hard disks, attaching any optional USB devices, attaching the storage system to your network, and powering up the system. For information about this step, see "Step Two: Set up Your storage system" on page 13. 3. Install the Storage System Console. You will need the Storage System Console to initialize your hard disks in step 4. For information about this step, see "Step Three: Install the Storage System Console" on page 16 4. Initialize the Hard Disks. This step loads firmware from the storage unit's memory to each disk. "Step Four: Initialize the Hard Disks" on page 17. 5. Configure your storage system. Before you can use your storage system, you must perform some initial configuration tasks, like setting the date and time, and specifying how much space to use for file sharing and how much to use for backups. The System Setup wizard guides you through this process. For information about this step, see "Step Five: Configure your Storage System" on page 20. If you bought your Serial ATA 4-Drive NAS with the disks already installed and configured, and you do not want to change your disk configuration, skip step one and proceed with "Attaching USB Devices" in step two on page 15. Step One: Determine Your Configuration Before you start the physical installation of your storage system, decide which configuration is best suited to your needs. The configuration that you choose may affect the order in which you load the disks into your storage system, and you will need to specify your configuration choice when you reach "Step Five: Configure your Storage System". Each supported configuration has a different balance of desirable characteristics, as shown in the table below. The configurations available to you depend on the number of disks installed in your storage system. Use this table to select your configuration based on the number of disks you intend to use and the characteristics that are of the highest priority to you.

Step Two: Set up Your storage system Setting up your storage system consists of the following steps: Installing the Hard Disks Attaching USB Devices Connecting the Storage System to the Network Powering Up the Storage System Installing the Hard Disks If you have fewer than four hard disks in your storage system, you might want to add more at this time. You can add disks later, but changing your disk configuration once the disks contain data might cause data loss. Note: The storage system must have at least one SATA hard disk with a capacity of at least 80 GB. USRobotics strongly recommends that you install all the hard disks that you want to use in the storage system at this time in order to avoid data loss. USRobotics also recommends that you use 4 disks of the same size for optimum performance. Getting Started - 13 Serial ATA 4-Drive NAS User Guide To install the hard disks, you need a Phillips head screwdriver. 1. Remove the top hard disk tray from the storage system: 2. Near the front of the tray is a spacer containing four screws. Squeeze the tabs together to remove the spacer from the tray. 3. With the flat edge of the spacer up and the screws facing a flat surface (such as a table or desk top), flex the sides of the spacer apart from each other to release the screws. 4. Make sure that the hard disk is a SATA disk. It should have a SATA connector similar to the following: 5. Slide the new hard disk into the tray (connector end down and toward the back of the tray), and fasten Getting Started - 14 Serial ATA 4-Drive NAS User Guide the screws on the sides of the tray: 6. Slide the hard disk and tray back into the storage system until it snaps into place. If you have fewer than four disks, load the bottom trays first and leave the top tray or trays empty. If you have four disks that are not the same size and you intend to use RAID 10, USRobotics recommends that you load the disks in ascending order of disk capacity, starting with the smallest disk in the bottom slot (slot 1), Notes: · · If you install a hard disk that was previously part of a RAID, it will rebuild automatically. If you later replace all of the disks with higher-capacity disks, you will have to format those disks. For more information about disk configurations, see the "Disk Configurations" on page 107. 7. Repeat steps 1 through 6 for each disk that you will use in your storage system. Attaching USB Devices If you have USB storage devices or printers, you can attach them to the USB ports on the back of the storage system. Note: USB hubs are not supported. In addition, any USB disk must be formatted before you use it with the storage system, and only the first partition of a FAT or FAT32 file system will be recognized. Do not attach the storage system directly to a USB port on a computer. Connecting the Storage System to the Network To connect your storage system to your network, insert one end of the supplied RJ-45 Ethernet cable into the Ethernet port on the back of the storage system. Then insert the other end into a network port. Getting Started - 15 Serial ATA 4-Drive NAS User Guide Powering Up the Storage System To power up the storage system, insert the power cable into the power connector on the back of the storage system and plug the other end into a power outlet. Note: USRobotics recommends that you plug the storage system into a surge protector or uninterruptible power supply to prevent damage to the system from power surges. Once you have connected the power cable, make sure that the power switch on the back of the storage system is set to the on position. Then press and release the power button on the front of the storage system. The power and Disk LEDs flash while the storage system is booting. Once the system has finished booting, the Disk LEDs stop flashing. If the hard disk installation was successful, the Disk LED is blue. If there is a problem, the Disk LED is off. If this occurs, shut down the system, remove and inspect the hard disk for any installation problem, and reinstall it. To shut down the system, press and hold the power button for approximately five seconds until the Disk LEDs start flashing. Then release the power button; the storage system will shut down after a short period. Step Three: Install the Storage System Console Install the Storage System Console on a computer on the same network as the Serial ATA 4-Drive NAS: 1. Insert the USRobotics Installation CD-ROM into your CD-ROM drive. 2. If prompted, select your preferred language, then review the License Agreement and click Yes. The installation CD prompts you to make a choice: 3. Select Console Installation. Getting Started - 16 Serial ATA 4-Drive NAS User Guide The installation wizard appears. 4. Follow the on-screen prompts to install the Storage System Console. When installation is complete, the following window appears: 5. Click Finish. Step Four: Initialize the Hard Disks To initialize the hard disks, follow these steps: 1. Start the Storage System Console: click Start > Programs > Storage System Console. Getting Started - 17 Serial ATA 4-Drive NAS User Guide The Storage System Console appears: 2. In the left pane, click the name of the storage system. Then click Log On Storage System Manager. If you see the Login page, your storage system was initialized and configured before you bought it. You are finished with the installation procedure and can begin using your Serial ATA 4-Drive NAS system, or you can reconfigure your disks if you choose to do so. Skip the remaining installation steps and proceed with "Accessing the Web User Interface" on page 24. Getting Started - 18 Serial ATA 4-Drive NAS User Guide If the System Initialization page appears, you need to initialize your disks: If not all the hard disks have been detected, or if you want to add, remove, or reorder the disks at this time, insert or remove the disks one at a time and click Scan after each action. If you're adding disks, be sure to wait until the Disk LED is blue before you click Scan. Note: USRobotics strongly recommends that you install all the hard disks that you want to use in the storage system at this time, since changing the number of hard disks later can require disk reconfiguration and possible data loss. 3. Click Browse and locate the USRobotics Installation CD-ROM. 4. Open Firmware\fs-usr-1.0-b106.pkg. 5. On the System Initialization page, click Upload. The firmware on the storage system's internal flash memory is uploaded to the hard disks. Getting Started - 19 Serial ATA 4-Drive NAS User Guide When this process is complete, the storage system restarts and displays the welcome page: Step Five: Configure your Storage System Once initial setup has been completed, follow these steps to run the System Setup wizard and perform the necessary initial configuration: 1. On the welcome page, click Next. The End User Software License Agreement page appears. 2. If you agree to the terms, select I accept the license agreement and click Next. The Host Name page appears. 3. Click Next to accept the default storage system name (USR8700) OR Enter the name that you prefer and then click Next. The storage system name can be up to 15 characters long and can include letters, numbers, and hyphens. When you click Next, the Date/Time page appears: Specify the current date, time, and time zone, and then click Next. Getting Started - 20 Serial ATA 4-Drive NAS User Guide Specify the time using the 24-hour format. For example, enter 2:00 P.M. as 14:00:00. When you click Next, the Network Settings page appears: 4. By default, if your network has a DHCP server, the storage system obtains an IP address automatically from that server. If your network does not have a DHCP server, the default IP address and subnet mask are used. (The default IP address is 192.168.0.101, and the default subnet mask is 255.255.255.0). To accept the default settings, click Next. Otherwise, specify the desired settings and then click Next. The Disk Configuration page appears. The options that appear on this page vary depending on the number of hard disks that are currently installed in the system. Getting Started - 21 Serial ATA 4-Drive NAS User Guide 5. Select the configuration that you chose from the table on page 12 and click Next. By default, the storage system selects the configuration that provides the best level of data protection available: for a single disk, a linear configuration; for two disks, RAID 1; and for three or four disks, RAID 5. If you want to change the disk configuration, select the desired RAID level and then click Next. If you want to add or remove hard disks, do so one at a time. For each disk, wait until the Disk LED is blue and click Scan. When you are finished adding disks, select your configuration and click Next. When you click Next, the Disks to Back Up screen appears: 6. In the Number of disks to back up list, select the total number of disks that you plan to back up to this storage system. The maximum number of disks you can back up is 25. If you don't plan to back up any disks, select 0, click Next, and go to step 9. If you leave this field blank, 70% of your storage space will be allocated for backups, and 30% will be allocated for shared folders. If some computers have multiple disks, be sure to select the total number of disks that you plan to back up. For example, if your network has five computers and each computer has two hard disks, you should select 10. When you select a number, a corresponding number of text boxes (Disk 1, Disk 2, etc.) appear in Getting Started - 22 Serial ATA 4-Drive NAS User Guide Capacity of drives: 7. In each text box, enter the size of each disk that you plan to back up (specify the size in gigabytes). To determine the size of a computer's disk, open My Computer or Windows Explorer on that computer, right-click the disk, and then click Properties. Be sure to enter the entire capacity of each disk, not just the amount of used disk space. If a disk is smaller than 1 GB, divide the number of megabytes by 1024. For example, a 512-MB disk would be .5 GB (512 divided by 1024 is .5). Note: Only 99% of the available storage space can be allocated for backups. If the amount of disk space you need exceeds that limit, you will not be able to back up all the disks. When you click Next, the Disk Space Distribution page appears: Getting Started - 23 Serial ATA 4-Drive NAS User Guide 8. To accept the suggested percentages for file sharing and backup, click Finish. To change these proportions, enter a new percentage in either text box. (When you click anywhere on the page, the other text box updates automatically so that both percentages add up to 100%.) Then click Finish. Caution: If you reduce the recommended amount of space to use for backups, you might not be able to back up as many disks or use the maximum allowed number of backup versions. The recommended amount of space is greater than the total size of all your disks to accommodate multiple backup versions. If you change these proportions after you finish the wizard, you will lose all data in your shared folders and all existing backups. Backup of computer disks is provided through a separate backup and recovery utility. You can install DiskSafe Express from the USRobotics Installation CD-ROM for this purpose. For more information about DiskSafe Express, see the "Protecting Local Disks" on page 77. 9. in the confirmation window, click OK. The Configuration page appears and the system is configured according to the settings you specified. Once the configuration is complete, the system restarts Congratulations. You have successfully completed the installation procedure. Please register your Serial ATA 4-Drive NAS at www.usr.com/productreg/. Accessing the Web User Interface Once you have completed the initial configuration of your storage system, you can access the Web User Interface to add users, create shared folders, and perform other tasks related to managing your storage system. There are two ways to access the Web User Interface: · · Using a Web browser (Microsoft Internet Explorer 6.0 or Firefox 1.06 or newer) Using the Storage System Console (a Windows application that must be installed on each computer where you want to use it) Using a Web browser, you can access the Web User Interface from any computer in your network, but you must know the name or IP address of the storage system. In addition, if you configured the storage system Getting Started - 24 Serial ATA 4-Drive NAS User Guide to use a specific IP address, you might need to specify the IP address of the gateway in your network before you can successfully access the Web User Interface using a Web browser. First access the Web User Interface using the Storage System Console and then specify the gateway address (as described in "Changing the Network Settings" on page 64.) and try to access it using a Web browser. Using the Storage System Console, you can access the Web User Interface only from a computer in the same subnet as the storage system, but you do not have to know the name or IP address of the storage system or otherwise modify the network settings. Note: The Storage System Console launches a Web browser, so the computer where you install the Storage System Console must have Microsoft Internet Explorer 6.0 or Firefox 1.06 or newer installed as well. Accessing the Web User Interface Using a Web browser To access the Web User Interface using a Web browser: 1. From any computer in your network, run Microsoft Internet Explorer 6.0 or Firefox 1.06 or newer, enter the following in the address bar, and then press Enter: http://storage_system where storage_system is the name or IP address of the storage system. Note: You can use the storage system name only if that name is registered with a DNS server on your network. When the login page appears, you can bookmark it so that you can quickly and easily access it the next time. 2. Log in to the Web User Interface (as described in "Logging In to the Web User Interface" on page 26). Accessing the Web User Interface Using the Storage System Console If you want to access the Web User Interface using the Storage System Console, you must install the Storage System Console on each computer from which you plan to manage the storage system. You can install the Storage System Console on any computer that runs one of the following operating systems: · · · Microsoft Windows Server 2003 Microsoft Windows XP Microsoft Windows 2000 Professional, Server, or Advanced Server with Service Pack 2 or newer To install the Storage System Console, follow the instructions in "Step Three: Install the Storage System Console" on page 16. Running the Storage System Console Once you have installed the Storage System Console, you can run it and access the Web User Interface: Getting Started - 25 Serial ATA 4-Drive NAS User Guide 1. Click Start > Programs > Storage System Console. As soon as you start the Storage System Console, it automatically scans the network for storage systems. This might take a few minutes. As soon as the scan is complete, the left pane displays a tree view of all the storage systems it found: Note: If you connect a storage system to the network after the Storage System Console has already scanned it, or if you change the IP address of the storage system, you must click Discover Storage Systems to scan the network again and update the tree in the left pane. 2. In the left pane, select the name of the storage system that you want to manage (for example, Storage), and then click Log On Storage System Manager. 3. Log in to the Web User Interface (as described in "Logging In to the Web User Interface" on page 26). Logging In to the Web User Interface Whether you access the Web User Interface using a Web browser or the Storage System Console, the Getting Started - 26 Serial ATA 4-Drive NAS User Guide login page appears. This ensures that only authorized individuals can change the storage system settings. To log in, enter the administrator user name and password, and then click Log In. The default administrator user name is admin, and the default password is storage. (These are casesensitive.) However, you can change the name and password at any time. For more information, see "Changing the System Settings" on page 61. You can also change the language to use for the Web User Interface by clicking the desired language button. Getting Started - 27 Serial ATA 4-Drive NAS User Guide Navigating the Web User Interface Once you log in to the Web User Interface, the Home page appears: The top of the Home page (and every page in the Web User Interface) displays a navigation bar that lets you access all the features of the storage system: · Home--Displays information about the total storage capacity on the storage system, how much disk space is allocated for shared folders, how much is allocated for backups, and how much is used for each. (Initially, there is no used space.) This page also displays total number of shared folders and the number of networked computers (backup clients) that have backed up one or more disks on the stor- Getting Started - 28 Serial ATA 4-Drive NAS User Guide age system. Note: The total storage capacity will be less than the total size of all your hard disks because some of the disk space is needed for the operating system and management software. In addition, the amount of used backup capacity will be greater than the total size of all the disks listed on the Backups page because additional storage space is needed for the data that has changed between backups. On the Home page, you can also click Current Connections: This displays information about Windows and Mac OS X users who are currently connected to shared folders, including which shared folder they are accessing and when they logged on. Notes: · If anyone accessed a shared folder using the guest user name (which is described in more detail in "Adding Users" on page 30), guest appears in the Users column, followed in parentheses by the computer name. Due to the nature of the NFS protocol, Linux and other Mac connections are not listed on this page. Likewise, ongoing backup or recovery activities do not appear on this page. This page indicates only that a connection with a shared folder has been established; this does not necessarily mean that the user has opened any files in the shared folder. · · · Users--Displays a list of all currently configured users and lets you add, modify, and remove users. For Windows and Mac OS X users, this area also lets you add, modify, and remove groups. For more information, see "Adding Users" on page 30 and "Managing Users" on page 43. · Shared Folders--Displays a list of all currently configured shared folders and lets you add shared folders, change which users can access them, and remove them. For more information, see "Creating Shared Folders" on page 33 and "Managing Shared Folders" on page 50. · Backups--Displays a list of all computer disk backups that currently exist and lets you change the recovery CD password or delete the backups for a particular computer hard disk. For more information, see "Managing Backups" on page 55 and Chapter , "Protecting Local Disks," beginning on page 77. · Advanced--Provides access to advanced storage system configuration options, such as setting up email alerts; upgrading the firmware; removing USB devices; changing the system, network, or disk configuration settings; viewing information about system events; and shutting down the system Getting Started - 29 Serial ATA 4-Drive NAS User Guide remotely. For more information, see Chapter , "Managing Your Storage System," beginning on page 43. · · Contact Us--Provides information about USRobotics and the other products and services it offers. Log Out--Logs you out of the Web User Interface. Adding Users By default, the storage system includes a user named guest that has a password of guest. However, you might want to add other users as well. For example, if you want to restrict access to a shared folder that contains confidential information, you would add at least one user and authorize that user to access that shared folder (and not authorize the guest user to access it). Adding a user for each individual or computer in your network provides maximum flexibility and security, enabling you to control exactly who can access what information. In addition, only Windows and Mac OS X users can use the guest user name. If there are Linux users or Mac users who aren't using OS X in your network, you must add users to allow those individuals to access any shared folders. When you add a Windows or Mac OS X user, a folder with the same name as that person's user name is automatically created on the storage system. Only that person can access that folder, and that person has full read/write access to it. (In the Storage System Console, this folder is identified as the home folder.) You can add up to 64 Windows or Mac OS X users, and up to 64 Linux or other Mac users (for a total of up to 128 users). Note: Since each Linux/other Mac user can represent multiple users, the number of actual users can be higher. To add a user: 1. In the navigation bar, click Users. Getting Started - 30 Serial ATA 4-Drive NAS User Guide The Users & Computers page appears: 2. Click Add. 3. Select the type of user that you want to add, and then click Next. The operating system used by the user determines which option you should choose--Windows/Mac OS X user (CIFS) or Linux/Other Mac user (NFS). Note: Linux users and Mac users who are not using OS X access shared folders using the Network File System (NFS). In this environment, access to shared folders is given to entire computers, not to individual users of those computers. However, in Windows and Mac OS X environments, each computer user can have individual access to a shared folder. The page that appears next varies, depending on the user type you selected. Getting Started - 31 Serial ATA 4-Drive NAS User Guide · Windows/Mac OS X user (CIFS) · Linux/Other Mac user (NFS) Getting Started - 32 Serial ATA 4-Drive NAS User Guide 4. Enter the requested user information and click Done: For this type of user Do this Windows/Mac OS X user (CIFS) Enter the user name and password for accessing the shared folders. (You must enter the password a second time to confirm it.) The user name can be up to 20 characters long and can include letters and numbers. Note: If the user name and password that you specify here are the same as the person's Windows user name and password, the person will not be prompted to provide a user name and password when accessing the shared folder. Linux/Other Mac user (NFS) Enter a computer description and the IP address or computer name of the person's computer. The Computer description can be the name of the person who typically uses the computer, or any other description that you want to provide to identify the computer in the Users list. This description can be up to 15 characters long. The IP address or computer name is the IP address or the actual computer name in the computer's system configuration. Note: Note: You can create a single user that actually represents multiple computers. In the IP address or computer name text box, you can use the wildcard characters * and ? to indicate a range of names. For example, client* or client? would include all computers in the subnet whose name begins with client. *.company.com would include all computers in the domain company.com. However, these wildcards cannot be used with IP addresses. The specified user name and type appears in the list on the Users & Computers page. 5. Repeat steps 2 through 4 until you have added all the users that you want to add at this time. (You can always add more users later.) To put Windows or Mac OS X users into groups, see "Working with Groups" on page 46. Creating Shared Folders By default, the storage system includes a shared folder named public, and all Windows and Mac OS X users can access it and create, modify, or delete files there (unless you change the list of authorized users or their access rights as described in "Changing User Access to Shared Folders" on page 51). However, you might want to create other shared folders as well. For example, in an office environment, you might want to create a shared folder for company policies that everyone can only view, and separate shared folders for confidential business files that only selected individuals or departments can view or change. In a home environment, you might want to create separate folders for different types of files, like photos, videos, or music. In addition, since only Windows and Mac OS X users can access the public folder, you would have to create shared folders if your network includes Linux or other Mac users. You can create up to 64 shared folders. Users who can access and write to these shared folders can create additional sub-folders for organizing the files they store there. To create a shared folder: Getting Started - 33 Serial ATA 4-Drive NAS User Guide 1. In the navigation bar, click Shared Folders. The Shared Folders page appears: Note: The Shared folders list includes usbdisk1 and usbdisk2, whether or not any USB disks have been connected to the storage system. In addition, shared folders created as the result of adding a Windows/Mac OS X user do not appear in the Shared folders list. 2. Click Add. 3. Specify which type of user will be accessing this shared folder, and then click Next. The operating system running on the user's computer determines which option you should choose-- Windows/Mac OS X users (CIFS) or Linux/Other Mac users (NFS). The page that appears next varies, depending on the user type you selected. Getting Started - 34 Serial ATA 4-Drive NAS User Guide · Windows/Mac OS X user (CIFS) · Linux/Other Mac user (NFS) 4. In the Shared folder name text box, enter a unique name for the shared folder, and then click Next. This name can be up to 256 characters long and can contain letters, numbers, hyphens, underlines, and spaces. Note: Each shared folder name must be unique. For example, if you create a shared folder named Photos for Windows/Mac OS X users, you cannot subsequently create a shared folder named Photos for Linux/other Mac users.\ In addition, the shared folder name cannot be the same as any Windows Mac OS X user name. For Linux/other Mac users, the Mount path indicates that path that those users will specify when accessing the shared folder (as described in "Accessing Shared Folders" on page 37). As you enter a shared folder name in the text box, the same name is appended to the mount path. (You cannot change the first part of the mount path--/nas/NASDisk-00002/.) The page that appears next varies, depending on the user type you selected. Getting Started - 35 Serial ATA 4-Drive NAS User Guide · Windows/Mac OS X user (CIFS) · Linux/Other Mac user (NFS) 5. In the Unauthorized users list, select the name of the user(s) who should be able to access this shared folder. To select multiple, contiguous users, hold down the Shift key and select the first user, then select the last user. All users between the first and last selected user are selected. To select multiple, non-contig- Getting Started - 36 Serial ATA 4-Drive NAS User Guide uous users, hold down the Ctrl key as you select each user. Then specify what access rights the selected user(s) should have: To allow the user(s) to do this Only read the files in the shared folder and its subfolders Read, add, modify, and delete the folders and files in the shared folder Click this Add (Read-Only) Add (Read/Write) The selected user(s) move from the Unauthorized users list to the Authorized users list. If you accidentally add a user that you didn't mean to add, select the user in the Authorized users list and click Remove. The user returns to the Unauthorized users list. Note: If you created groups (as described in "Adding a Group" on page 47), you can perform this step with the Unauthorized groups list. This page shows all groups and all users. For example, if you created a group named Group1, and added User2 and User3 to that group, the Unauthorized groups list includes Group1, and the Unauthorized users list includes User2 and User3. If you select Group1 and click Add (Read-Only), Group1 moves to the Authorized groups list, but User2 and User3 do not move to the Authorized users list. This allows you to specify unique access rights for those users. For example, you could select User3 and click Add (Read/Write). This would mean that everyone in Group1 would have read-only access to the shared folder except User3, who would have read/write access to it. On the Shared Folders page, the group name in the Users with access column is preceded by an @ symbol. 6. Repeat step 5 until you have defined all the desired access rights for all the desired users and groups, and then click Done. 7. Repeat steps 2 through 6 until you have created all the shared folders that you want to create at this time. (You can always create more shared folders later.) When you have finished, you can log out (as described in "Logging Out of the Web User Interface" on page 72), or you can explore more of the features that the storage system has to offer. (For more information, see Chapter , "Managing Your Storage System," beginning on page 43.) Accessing Shared Folders Once you have added users and created shared folders, the users need to perform some simple steps to be able to access those folders. The procedure for doing this varies, depending on the user's operating system. Each user can access only those shared folders that the user is authorized to access. Note: If you change the IP address of the storage system, users who accessed the shared folders using the previous IP address will be disconnected and must repeat the procedures described below using the new IP address. Getting Started - 37 Serial ATA 4-Drive NAS User Guide Windows Users If you're using Windows, you have two options for accessing shared folders: you can use My Computer or Windows Explorer to map a drive letter to the shared folder, or you can install the Storage System Console and use that utility to map a drive letter to the shared folder. With the Storage System Console, you don't have to worry about remembering the name of the storage server or the shared folders; it displays them automatically. However, the computer where you install the Storage System Console must be on the same network as the storage system. Using My Computer or Windows Explorer To access a shared folder using My Computer or Windows Explorer: 1. Open My Computer or Windows Explorer. 2. From the Tools menu, click Map Network Drive. The Map Network Drive dialog box appears: The exact appearance of this dialog box varies, depending on your operating system. 3. In the Drive list, select the drive letter that you want to assign to the shared folder. 4. In the Folder text box, enter the following: \\storage_system\shared_folder where storage_system is the name or IP address of the storage system, and shared_folder is the name of the shared folder. For example, if the storage system name is Storage and the shared folder name is Photos, you would enter the following: \\Storage\Photos Note: You can use the storage system name only if that name is registered with a DNS server on your network. Alternatively, you can click Browse and select the shared folder from the Microsoft Windows Net- Getting Started - 38 Serial ATA 4-Drive NAS User Guide work. 5. To automatically connect to this shared folder each time you log on to Windows, select Reconnect at logon. If you clear this option, you must repeat this procedure each time you want to access the shared folder. 6. Click Finish. 7. If prompted, enter your user name and password for accessing this shared folder, and then click OK. Note: If the user name and password for accessing the shared folder are the same as your Windows user name and password, you are not prompted to provide a user name and password to access the shared folder. In addition, once you provide your user name and password for accessing one shared folder, you are not prompted to provide it again when you access other shared folders to which you have access rights. If the guest user has access to this shared folder, you can use guest as both the user name and password. You can now access the shared folder from My Computer or Windows Explorer. Using the Storage System Console To access a shared folder using the Storage System Console: 1. Install the Storage System Console (as described in "Step Three: Install the Storage System Console" on page 16). 1. Click Start > Programs > Storage System Console. As soon as you start the Storage System Console, it automatically scans the network for storage systems. This might take a few minutes. As soon as the scan is complete, the left pane displays a tree view of all the storage systems it found: Getting Started - 39 Serial ATA 4-Drive NAS User Guide Note: If you connect a storage system to the network after the Storage System Console has already scanned it, or if you change the IP address of the storage system, you must click Discover Storage Systems to scan the network again and update the tree in the left pane. 2. In the left pane, double-click the name of the storage system that contains the shared folders that you want to access. The storage system name expands to display all the available shared folders. Those shared folders that can be accessed using the guest user name and password are listed first: 3. In the left pane, select the shared folder that you want to access and then click Map Drive Letter. Note: The home item provides only you with access to a shared folder that is unique to your user name. The Map Network Drive dialog box appears: The exact appearance of this dialog box varies, depending on your operating system. Getting Started - 40 Serial ATA 4-Drive NAS User Guide 4. In the Drive list, select the drive letter that you want to assign to the shared folder. 5. To automatically connect to this shared folder each time you log on to Windows, select Reconnect at logon. If you clear this option, you must repeat this procedure each time you want to access the shared folder. 6. Click Finish. 7. If prompted, enter your user name and password for accessing this shared folder, and then click OK. Note: If the user name and password for accessing the shared folder are the same as your Windows user name and password, you are not prompted to provide a user name and password to access the shared folder. In addition, once you provide your user name and password for accessing one shared folder, you are not prompted to provide it again when you access other shared folders to which you have access rights. If the guest user has access to this shared folder, you can use guest as both the user name and password. You can now access the shared folder from My Computer or Windows Explorer. Linux Users To access a shared folder on a computer running Linux: 1. Create a directory by entering the following command at the command prompt: mkdir /my_directory where my_directory is the name of the directory. Be sure to include the full path to the directory (for example, /mnt/my_directory). 2. If desired, display a list of all the available shared folders by entering the following command: showmount -e storage_system where storage_system is the name or IP address of the storage system. Note: You can use the storage system name only if that name is registered with a DNS server on your network. 3. Mount the desired shared folder by entering the following command: mount storage_system:/nas/NASDisk-00002/folder /my_directory where storage_system is the name or IP address of the storage system, folder is the name of the shared folder, and my_directory is the name of the directory that you created in step 1. Getting Started - 41 Serial ATA 4-Drive NAS User Guide If you included a full path when creating the directory, be sure to include the full path with this command (for example, mount storage_system:/nas /NASDisk-00002/folder /mnt/my_directory). 4. Repeat steps 1 through 3 for each shared folder that you want to access. Mac Users The procedure for accessing a shared folder on a Mac varies, depending on whether the Mac is running OS X or an older operating system. (Macs running OS X can access the same shared CIFS folders as Windows users. Mac running older operating systems can access the same shared NFS folders as Linux users.) Mac OS X To access a shared folder on a Mac running OS X: 1. From the Go menu, click Connect to Server. 2. In the Address text box, enter the following and click Connect: smb://storage_system where storage_system is the name or IP address of the storage system. Note: You can use the storage system name only if that name is registered with a DNS server on your network. 3. In the Select a share list, select the name of the shared folder that you want to access and then click OK. 4. Enter the user name and password for accessing this shared folder, and then click OK. If the guest user has access to this shared folder, you can use guest as both the user name and password. An icon with the name of the shared folder is created on the desktop. 5. Repeat steps 1 through 4 for each shared folder that you want to access. 6. To access the shared folder, double-click the icon on the desktop. Other Mac Operating Systems For information about accessing a shared folder using NFS on a Mac running an operating system older than OS X, please refer to your Mac documentation. Getting Started - 42 Serial ATA 4-Drive NAS User Guide Managing Your Storage System The Web User Interface lets you perform a number of tasks to help you get the most from your storage system: · · Managing Users--Add, modify, or remove users, or put users into groups. Managing Shared Folders--Create shared folders, rename existing shared folders, change which users can access existing shared folders or their access rights, and delete shared folders that you no longer want to keep. Managing Backups--View which computer disks are backed up, change the password for recovering a backup, or delete a backup. Setting Up E-mail Alerts--Specify whether or not e-mail notifications should be sent when a problem occurs, and who should receive the notifications. Upgrading the Firmware--Upgrade your storage system firmware to the latest version. Disconnecting USB Devices--If you're using optional USB devices, you must disconnect them using the Web User Interface before you physically unplug them. Changing the System Settings--Change the storage system name or time and date settings, as well as the user name or password for logging in to the Web User Interface. Changing the Network Settings--Change the workgroup name, the storage system's IP address(es), the gateway or DNS server settings, or the settings that allow the storage system to act as a DHCP server or FTP server. Reconfiguring Your Storage System Disks--Change the proportions of your storage system that are allocated to shared folders and backups, or change your disk configuration. Logging Out of the Web User Interface--Log out of the Web User Interface so that no one else can use your computer to make changes to the storage system. Shutting Down the Storage System--Shut down the storage system using the Web User Interface rather than pushing the power button on the storage system manually. · · · · · · · · · Managing Users When you click Users in the navigation bar, the Users & Computers page appears. This page displays a Managing Your Storage System - 43 Serial ATA 4-Drive NAS User Guide list of all currently configured Windows and Mac OS X users, as well as all Linux and other Mac computers. Only the individuals or computers that appear on this page can access the shared folders or back up their local hard disks on the storage system. (In this guide, the term user refers to both individuals and computers.) You can add, modify, or remove users at any time. Windows and Mac OS X users can also be put into groups. Putting users into groups makes it easier to give several users access to the same shared folder at once. For example, in an office environment, you might create one group for all users and give that group read-only access to a shared folder with corporate policies. You might then create separate groups for each department (such as Sales or HR) and give those groups read/write access to shared folders with information specifically for those groups (such as expense reports or company benefits). Each user can be a member of multiple groups. Adding Users To add a user, refer to "Adding Users" on page 30. Modifying Users For Windows and Mac OS X users, you can change the password used to access the shared folders, but not the user name. This change will not affect current connections, but will take effect the next time that a user tries to connect to a shared folder. For Linux and other Mac users, you can change the IP address or computer name, but not the computer description. Changing this information immediately disconnects that computer from the shared folders. Note: To change the user name or computer description, you must remove the existing user as described in "Removing Users" on page 46, and then add a new user with the desired name or description as described in "Adding Users" on page 30. To modify a user: Managing Your Storage System - 44 Serial ATA 4-Drive NAS User Guide 1. In the navigation bar, click Users. 2. Select the radio button next to the user that you want to modify. 3. Click Edit. The page that appears next varies, depending on the type of user you selected: · Windows/Mac OS X user (CIFS) · Linux/Other Mac user (NFS) 4. Make the desired change and click OK: For this type of user Do this Windows/Mac OS X user (CIFS) Enter the password for accessing the shared folders. (You must enter the password a second time to confirm it.) Note: If the user name and password specified here are the same as the person's Windows user name and password, the person will not be prompted to provide a user name and password when accessing the shared folders. Managing Your Storage System - 45 Serial ATA 4-Drive NAS User Guide For this type of user Do this Linux/Other Mac user (NFS) Enter the computer's IP address or the actual computer name in the computer's system configuration. A single user can actually represent multiple computers. In the IP address or computer name text box, you can use the wildcard characters * and ? to indicate a range of names. For example, client* or client? would include all computers in the subnet whose name begins with client. *.company.com would include all computers in the domain company.com. However, these wildcards cannot be used with IP addresses. Note: If the user is currently connected to a shared folder, changing this information will disconnect the user. Removing Users You can remove any user except the guest user. If you remove a user who is currently connected to the storage system, that user remains connected until the user disconnects from the shared folder or shuts down the computer. Caution: When you remove a Windows/Mac OS X user, the folder whose name matches that user name is automatically deleted. If you're removing the user simply to change the person's user name, you might want to have the user copy any data from this folder to another location to ensure that it is not lost. To remove a user: 1. In the navigation bar, click Users. 2. Select the radio button next to the user that you want to remove. 3. Click Remove. 4. When prompted to confirm the removal, click Yes. The user no longer appears in the list on the Users page. Working with Groups Windows and Mac OS X users can be put into groups, which makes it easier to give several users access to the same shared folder at once. When you click Users in the navigation bar and click Groups in the left pane, the page displays a list of all currently configured groups. When you select a group in the Groups list, the members of that group Managing Your Storage System - 46 Serial ATA 4-Drive NAS User Guide appear in the adjacent Members list. You can add a group, modify the group membership, or remove groups at any time. Adding a Group When you create a group, you typically specify which users should be members of that group, although you can create an empty group and add users later. (You must add users as described in "Adding Users" on page 30 before you can add those users to a group.) Each user can be a member of multiple groups. For example, the user Alice might be a member of both the Marketing and Executives groups. You can create up to 16 groups. To add a group: 1. In the navigation bar, click Users. 2. In the left pane, click Groups. Managing Your Storage System - 47 Serial ATA 4-Drive NAS User Guide 3. Click Add. 4. In the Group name text box, enter a unique name for the group. This name can be up to 20 characters long and can include letters, numbers, hyphens, and underlines. 5. Specify which users should belong to this group, and then click OK: To do this Add all users to the group Do this Click Add All Users. All users move from the Available users list to the Group members list. Add selected users to the group Remove all users from the group In the Available users list, select the user(s) that you want to add and then click Add Selected User(s).a Click Remove All Users. All users move from the Group members list to the Available users list. Remove selected users from In the Group members list, select the user(s) that you want to remove from the the group group and then click Remove Selected User(s).* a To select multiple, contiguous users, hold down the Shift key and select the first user, then select the last user. All users between the first and last selected user are selected. To select multiple, non-contiguous users, hold down the Ctrl key as you select each user. Changing the Group Membership You can change which users are members of each group at any time. When you add a user to a group, that user immediately has access to all the shared folders that the group is authorized to access. However, if you remove a user from a group, the change does not take effect until that user disconnects from the shared folder or shuts down the computer. For example, the user Alice might be a member of both the Marketing and Executives groups. The Managing Your Storage System - 48 Serial ATA 4-Drive NAS User Guide Marketing group might have read-only access to the Budget shared folder, while the Executives group might have read/write access. As a member of the Executives group, Alice would have read/write access to that shared folder. If Alice is currently connected to that shared folder and you subsequently remove her from the Executives group, she will continue to have read/write access to that folder until she disconnects or shuts down her computer. The next time she connects, she will continue to have access to the shared folder (since she is still a member of the Marketing group), but she will be able to only view the files there; she will not be able to add, modify, or delete any files. To change the group membership: 1. In the navigation bar, click Users. 2. In the left pane, click Groups. 3. In the Groups list, select the group whose membership you want to change. 4. Click Edit. 5. Specify which users should belong to this group, and then click OK: To do this Add all users to the group Add selected users to the group Remove all users from the group Do this Click Add All Users. In the Available users list, select the user(s) that you want to add and then click Add Selected User(s).a Click Remove All Users. Remove selected users from In the Group members list, select the user(s) that you want to remove from the the group group and then click Remove Selected User(s).* a To select multiple, contiguous users, hold down the Shift key and select the first user, then select the last user. All users between the first and last selected user are selected. To select multiple, non-contiguous users, hold down the Ctrl key as you select each user. Managing Your Storage System - 49 Serial ATA 4-Drive NAS User Guide The selected users move from one list to the other. On the Groups page, when you select this group in the Groups list, the adjacent Members list immediately reflects the changes you just made. Removing a Group Removing a group does not remove the users that are members of that group; it simply means that the group will no longer appear in the Groups list on the Groups page. The users remain listed on the Users & Computers page. However, removing a group can affect access to shared folders. When you remove a group, the members of that group will no longer have access to any shared folders that the group was authorized to access unless they were granted individual access as well. For example, the Executives group might include Alice, Bob, and Carlos, and that group might have read/ write access to the Budget shared folder. If you remove the Executives group, Alice, Bob, and Carlos remain users, but they will no longer have any access to that shared folder. On the other hand, if the Executives group had read/write access to the Budget shared folder, but Alice had read-only access, when you remove the group, Bob and Carlos will no longer have access to the Budget shared folder (since their access rights were determined by their group membership), but Alice will continue to have read-only access, since that access right was granted to her on a user level. To remove a group: 1. In the navigation bar, click Users. 2. In the left pane, click Groups. 3. In the Groups list, select the group that you want to remove. 4. Click Remove. 5. When prompted to confirm the removal, click Yes. The group no longer appears in the Groups list. Managing Shared Folders When you click Shared Folders in the navigation bar, the page displays a list of shared resources, including both shared folders and USB devices. When you select an item in the Shared folders list, the users and groups that can access that item appear in the Users with access list. (For groups, the group Managing Your Storage System - 50
