Installation and Set-up of Network Disk Server 2.1 Installing the Hardware The following steps will guide you through the Network Disk Server hardware installation: 1. Connect the Network Disk ServerTM to your Network. Note: The system provides two to three network ports. To configure Fail Over and Load Balance, at least two network ports must be connected. 2. If you want to back up your files to the tape, please connect the tape drive to the SCSI port on the back of your Network Disk Server. Then turn on the tape drive. (This function is only applicable for Network Disk Server models with SCSI port). 3. To use a UPS with your unit, please connect the UPS to the RS232 port on the back of your Network Disk Server via a serial cable. And connect the power plug of the Network Disk Server to the output power inlet of the UPS. (This function is only applicable for Network Disk Server models with SCSI port). 4. Power on the Network Disk ServerTM . Note: The power switch uses toggle switch design (after pushing the button it will return to the original position). All you need to do is to flip the switch one to turn-on or turn-off. 8 When all power cables have been properly connected, push the Power Switch on the back of the Network Disk Server. The LCD Panel will light up and the system is ready for set-up: Server Name Date NAS001122 192.168.0.1 05/22 02:48 8 $ IP Address Time At this time the hardware installation of your Network Disk Server is complete. Please proceed to "Set-up before First Operation". 2.2 Set-up before First Operation The factory default settings of your Network Disk Server will search the network via DHCP (Dynamic Host Configuration Protocol) to automatically detect IP address settings. If your network does not support the DHCP protocol, the Network Disk Server will use the default settings listed below: IP Address: 192.168.0.1 Subnet Mask: 255.255.255.0 Once the Network Disk Server completes its boot-up process, the LCD panel displays the current IP address settings. If your network does not support the DHCP protocol, you must configure your Network Disk Server to the proper LAN settings before using it for the first time. (If you do not know your LAN settings, please contact your network administrator). 1. Use the LCD panel to change the network settings. For more information, see Appendix A. 2. Use the Quick Install Wizard on the CD-ROM to change the network settings. For more information, see Appendix D. Once you complete the Network Disk Server settings, you can use your web browser to perform further administrative settings. 9 Chapter 3. Administration of Network Disk Server Once you have installed the Network Disk Server and other hardware and connected it to the networks, you can use your browser (supports Microsoft Internet Explorer 5.0 or later and Netscape Navigator 4.5 or later; Microsoft Internet Explorer 5.5 is recommended) to complete administrative tasks for the Network Disk Server. 3.1 Accessing the Administration Page The following methods allow administrator to access the Administration page: 1. Launch your web browser (Microsoft Internet Explorer version 5.5 is recommended). If you know the IP address of the Network Disk Server, type the IP address in the address bar of the browser and press "Enter". The IP address can also be obtained on the LCD display of the Network Disk Server (see Appendix A). 10 2. Use the Quick Installation Wizard (see Appendix D) and doubleclick on Network Disk Server in the list that appears. When the browser displays the home page of your Network Disk Server, click on the Administration link. Enter the user name and password to continue the administration setup. The default login name and password are as follows: Login: Administrator Password: admin If this is the first time you enter the Administration page, the Quick Configuration page appears automatically. Please refer to the Quick Configuration section for more details. 11 3.2 Server Administration 12 3.3 Quick Configuration The Quick Configuration will guide you through the configuration process step-by-step, as follows: Enter the name, workgroup and description for this server. Change the administrator password. Enter the date, time and time zone for this server. Select the language that this server will use for file names. Enter the IP address, subnet mask and default gateway for this server. 6. Select the network file services that you want to provide on this server. 7. Configure disk volume on this server. 8. Configure the method of user authentication. 9. Manage users and user groups for this server. 10. Manage network shares on this server. It might take 3 to 10 minutes to complete the Quick Configuration depending on the type of configurations. 1. 2. 3. 4. 5. 3.4 System Settings Basic system settings include the server name, d ate, time, and language settings. · Server Name You must assign a unique name for your Network Disk Server for ease of identification within the local network. The server name can accommodate as much as 14 characters, which can be a combination of letters (A-Z or a-z), numbers (0-9) and hyphens (-). The server will not accept name containing blank spaces, period (.), or names with only numbers. The LCD display will show the current server name. Next, you must configure your Network Disk Server to the workgroup. The workgroup represents a basic computer group within the Microsoft Network. Files are normally shared within the group. Workgroups can accommodate as much as 15 characters but must exclude the following characters: ;:"<>*+=\ | ? , [ ]/ The first character cannot be a period (.). For ease of management and usage, please set your Network Disk Server and attached computer(s) in the same workgroup. Moreover, the Network Disk Server allows you to specify comments (such as administrator name, department, or location) that describe the Network Disk Server for ease of identification to an on-line user. 13 · Date & Time Set the date, time, and time zone according to your current location. If the settings are incorrectly entered, the following problems may occur: 1. When using a web browser to access or save a file, the time of the file accessed or saved may be out of sync. 2. The system event log time will be incorrect compared to the actual time an action occurred. · Language Setting The server is based on the language settings and uses it accordingly while creating or displaying files and directories. Select the correct language settings to avoid the following problems: 1. Inability to create files or directories with special wording. 2. Inability to display files or directories name with special wording. l View System Settings You can view all the current system settings such as server name and workgroup from this page. 3.5 Network Settings The network settings include TCP/IP configuration and network service settings. · TCP/IP Configuration According to your local network, you can choose the following two methods to configure the TCP/IP settings: i. Obtain IP address settings automatically via DHCP If your network supports DHCP, the Network Disk Server will automatically use the DHCP protocol to retrieve the IP (Internet Protocol) address and related information. ii. Use static IP address Use the user defined IP address settings. · Fixed IP Address The IP address is a 32-bit digit code used to differentiate each single entity on a network. The IP address is separated into 4 groups of eight bits separated by dots: 192.168.0.1. 14 · Subnet Mask The subnet mask is used to define computer within the same local network. It is a 32-bits digit code: 255.xxx.xxx.xxx. · Default Gateway The gateway is generally referred as an interchange point that connects two networks, such as LAN and WAN. If you do not need to configure gateway address, set it as 0.0.0.0. · Enable DHCP Server Once the DHCP server's dynamic address allocation function is activated it will automatically assign dynamic addresses to any computer in the network that is configured to automatically obtain IP addresses. Note: Only one DHCP server may be activated at any time in a network to avoid causing conflicts in communication. Configuration of Network Interfaces The system supports multiple network interfaces that enable you to perform Fail Over and Load Balancing functions. Fail over ensures server availability to the network. If the primary port is disconnected due to a hardware or cable problem, the secondary port will replace its network identity. If the failed port resumes the network connection, it will also resume the role as the primary interface. · Microsoft Networking Users using the Network Disk Server on the Microsoft Windows operating systems must start Microsoft Network Services. If the local network has a WINS server installed, please specify the IP address. The Network Disk Server will automatically register its name and IP address with the WINS service. Or you can enable your Network Disk Server as the WINS server for your network. · Apple Networking Users using the Network Disk Server on Apple's Mac operating systems must enable AppleTalk network support. If your AppleTalk network uses extended networks, and is assigned with multiple zones, please assign a zone name to the Network Disk Server. If you do not want to assign a network zone, please enter an asterisk (*). Asterisk (*) is the default setting. 15 · NFS Service Users using Network Disk Server on Unix/Linux operating system computer or server must start Unix/Linux NFS service. The Network Disk Server supports NFS version 2.0/3.0. To correctly use the NFS service, you must assign a User's UID and IP address. Please select User Management · Users · NFS Settings to start the setup. · NetWare Service If you wish to use Net Ware to access the Network Disk Server, you must activate the NetWare service. The Network Disk Server will then operate in a manner similar to a Novell NetWare 3.12 file server. · Web Service Other than standard OS support, you have the choice to use a web browser to access your files on the Network Disk Server. If your Network Disk server is connected to the Internet and uses a valid IP address, the Network Disk Server allows you to access your files using a web browser from anywhere in the world. · FTP Service If you wish to download files from or upload files to your Network Disk Server by using file transfer protocol (FTP), you must first activate the FTP service. · View Network Settings You can view all the current system settings such as server name and workgroup from this page. 3.6 Disk Configuration Depending on the models, the Network Disk Server can accommodate a maximum of eight disks. T he Disk Volume can be configured according to your needs. · Single Disk You can choose to use a stand-alone disk. However, if the disk is damaged, all data will be lost. · RAID 5 Disk Volume Three or more hard disks can be teamed up to form a largecapaci y RAID 5 disk group. This system will distribute and store t data among its various member disks as it is received. At the same time it uses an amount of space roughly equivalent to a whole disk to store reference numbers with the same elements. Should one of the disks in the group suffer some kind of damage, you can shut down the computer and install a new disk, and the 16 system will restore the data on the new disk using the reference number. In addition, if you have a system with four disks but use only three in your RAID 5 group, the fourth will serve as a backup disk. If one of the three disks is damaged the system will automatically start using the spare disk without powering down and changing the affected disk. Generally speaking, the capacity of a RAID 5 disk group is one disk's worth of space less than the total rated capacity of the group. Note: RAID 5 may be used only with equipment that has three or more disks. · RAID 1 Mirroring Disk Volume Mirroring Disk protects your data by automatically backing up the contents of one disk onto the second disk of a mirrored pair. This protects your data if one of the disks fails. Unfortunately, the storing capacity is equal to a single disk, as the second drive is used to automatically back up the first. Mirroring Disk is suitable for personal or corporate use to store important data. · RAID 0 Striping Disk Volume Striping disk combines two or more disks into one larger disk. It offers the fastest disk access but it does not have any protection of your data if the striped array fails. The disk capacity equals the number of disks in the array times the size of the smallest disk. Striping disk is usually used to maximize your disk capacity or for fast disk access but not for storing important data. · Linear Disk Volume You can combine two or more disks into one larger disk. During file saving, the files are saved on physical disks sequentially but do not have a disk failure file protection function. The overall capacity of linear disks is the sum of all disks. Linear disks are generally used for storing large data and are not appropriate to use for file protection of important data. By factory default, the Network Disk Server has been pre-set into one large disk. If you wish to use other disk configurations, the settings can be changed during the first Quick Configuration access. Furthermore, to increase the hard disk life, the hard disk will go to standby mode if there is no access within 30 minutes. If any data access happens while the hard disk is in stand-by mode, it will take 3 or 5 seconds for the hard disk to return to normal mode. You can select System Tools · Hardware Settings to change the setting. You can also perform the following disk administration: · · · · · Create Disk Volume Delete Disk Volume Examine Disk Volume Format Disk Volume View Disk & Volume Status 17 In addition to the above functions, users can also perform snapshot taking in Snapshot Settings of System Tools. This function enables users to take a real-time and dynamic replication of the snapshot according to the disk volume at a certain point of time. The data contained in the snapshot is the same as the previously copied network hard disk drives. The content in the snapshot will not be affected even when changing the content of the disk volume. If an original data is damaged, it can be restored from the snapshot image. 3.7 User Management The Network Disk Server can share its files with multiple users. It is important to plan and organize users and user groups' accessibility to ease the administration work. · Users The factory default settings include the following users: Administrator By default, the administrator is a member of the administrators group and has access to the system administration. You cannot delete the user Administrator. Guest When you use a non-registered user name to login, the server recognizes it as a Guest and will allow limited access. A guest does not belong to any user group. You cannot delete the user Guest or create a password. Anonymous When you connect to the server by FTP service, you can use the name to login as a guest. You cannot delete this user or change its password. You can create a new user according to your needs. The following information is required to create a new user: · User Name The user name must not exceed 32 characters. It is case insensitive and it can contain double-byte characters. (Such as Chinese, Japanese, and Korean) But it cannot contain any of the characters below: " / \ [ ] : ; | = , + * ? < >` ' · Password The password must not exceed 16 characters. Due to security concerns, the password must be at least 6 characters. Try to avoid using codes that are easily decipherable. 18 You can perform the following settings for users: · · · · · · · Create User Create Multiple Users Create Private Network Share Assign User Groups NFS Settings Quota Settings Delete User · User Groups To administer access rights, you can create user groups. User groups are a collection of users with the same access rights to files or folders. By factory default, the server contains the following pre-defined user groups: Administrators All members of the administrator group have the rights to perform system management. You cannot delete the administrator group. Everyone All registered users belongs to everyone group. You cannot delete the user groups, "Everyone" or delete any of its users. You can manage user groups with the following options: · · · · Create User Groups Create Private Network Share Assign Users Delete User Groups User groups name must not exceed 256 characters. It is case insensitive and it can contain double-byte characters such as Chinese, Japanese, and Korean. But it cannot contain any of the characters below: " / \ [ ] : ; | = , + * ? < >` ' To properly manage security, it is very important to manage users and user groups. You may set the share access parameters of each user or user group accordingly. · PDC Authentication Settings If you have a Windows PDC (Primary Domain Controller) server to handle the domain security in your network, you don't need to reenter all the users and groups with the Network Disk Server. You can simply enable the PDC authentication feature; the Network Disk Server will connect with the NT domain and get all the information of the domain users and groups automatically. To enable PDC authentication, you must enter the domain name as well as the user name and password already established in this domain. The Network Disk Server will use the user name and password to log in to the NT domain and retrieve user and group information. Once you have configured the Network Disk Server to 19
