This Switch integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in a highly flexible package. Since this Switch's Port-1 to Port-24 are Power over Ethernet (PoE) ports, it will automatically detect the presence of IEEE 802.3afcompliant devices and will provide power through these PoE ports. The Switch provides up to 15.4Watts per port and can be connected to WLAN access points, IP phones, video cameras, and other PD devices. The Switch will automatically detect the network appliance's requirements, and the Switch will supply the required power current to each appliance. Purpose Thismanualdiscusses how to install your DES-1526. Terms/Usage In this manual, the term "Switch" (first letter upper case) refers to your DES-1526 and "switch" (first letter lower case) refers to other Ethernet switches. 1 INTRODUCTION This chapter describes the features of the DES-1526 and some background information about Fast Ethernet, Gigabit Ethernet, Switching, VLAN, and Power over Ethernet technologies. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times. Among them, 100BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution from the current 10BASE-T technology. The nondisruptive and smooth evolution nature, and the dominating potential market base, virtually guarantees cost-effective and high performance Fast Ethernet solutions. 100Mbps Fast Ethernet is a standard specified by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the CSMA/CD Ethernet protocol. Since 100Mbps Fast Ethernet is compatible with all other 10Mbps Ethernet environments, it provides a straightforward upgrade and takes advantage of the existing investment in hardware, software, and personnel training. 3 Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full-duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company's existing investment in hardware, software, and trained personnel. The increased speed and extra bandwidth offered by Gigabit Ethernet are essential to coping with the network bottlenecks that frequently develop as computers and their busses get faster and more users use applications that generate more traffic. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed up the traffic between your sub-networks. Gigabit Ethernet enables support for video conferencing, complex imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC's are able to perform 10 times the number of operations in the same amount of time. In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today and tomorrow's rapidly improving switching and routing internetworking technologies. 4 Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A switch increases capacity and decreases network loading by dividing a local area network into different segments, which do not compete with each other for network transmission capacity. The switch acts as a high-speed selective bridge between the individual segments. The switch, without interfering with any other segments, automatically forwards traffic that needs to go from one segment to another. By doing this the total network capacity is multiplied, while still maintaining the same network cabling and adapter cards. Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router, the setup, and maintenance required make routers relatively impractical. Today switches are an ideal solution to most kinds of local area network congestion problems. 5 VLAN (Virtual Local Area Network) A VLAN is a group of end-stations that are not constrained by their physical location and can communicate as if a common broadcast domain, a LAN. The primary utility of using VLAN is to reduce latency and the need for routers, using faster switching instead. Other VLAN utility includes: Security: Security is increased with the reduction of opportunity in eavesdropping on a broadcast network because data will be switched to only those confidential users within the VLAN. Cost Reduction: A VLAN can be used to create multiple broadcast domains, thus eliminating the need of expensive routers. 802.1Q VLAN: The VLAN tagging option is a standard set by the IEEE to facilitate the spanning of VLANs across multiple switches. (Reference: IEEE Std 802.1Q-1998 Virtual Bridged Local Area Networks.) 6 Power over Ethernet (PoE) Power over Ethernet (PoE) integrates power and data onto one single cabling infrastructure, eliminating the need to have AC power available at all locations. Power and Data are integrated onto the same cable. Supporting category 5/5e up to 100 Meters, PoE will provide power to PoE compatible devices, such as IP telephones, wireless LAN access points, and IP security cameras. PoE is already widely adopted in the market, saving up to 50% of overall installation costs by eliminating the need to install separate electrical wiring and power outlets. Features 24×10/100Mbps Auto-negotiation Fast Ethernet RJ-45 ports PoE enabled 2 x 1000BASE-T/mini-GBIC combo Gigabit Ethernet ports Compliant with 802.3af specification Supports PoE power up to 15.4W for each PoE port Supports PoE power maximum 170W for the device Supports PoE Powered Device (PD) classification identify Each port supports auto MDI/MDIX, so there is no need to use cross-over cables or an up-link port Full-duplex transfer mode for speed of 10Mbps, 100Mbps, and 1000Mbps Half-duplex transfer mode for speed of 10Mbps and 100Mbps Wire speed reception and transmission 7 Store-and-Forward switching scheme capability to support rate adaptation and ensure data integrity Up to 4K unicast addresses entities per device, self-learning, and table aging 768KBytes packet buffer Supports IEEE 802.3x flow control for full-duplex mode ports Supports Back-pressure flow control for half-duplex mode ports Supports 802.1Q VLAN Supports Port-based Trunking Supports Port-mirroring Supports Port-setting for Speed/Disable, Flow control, and Port based QoS (Quality of Service) Easy configuration via Web Browser Easy setting via Web Management Utility Standard 19" Rack-mount size 8 UNPACKING AND INSTALLATION This chapter provides unpacking and installation information for the Switch. Unpacking Open the shipping cartons of the Switch and carefully unpacks its contents. The carton should contain the following items: One DES-1526 One AC power cord, suitable for your area's electrical power connections Four rubber feet to be used for shock cushioning Screws and two mounting brackets CD-ROM with Web Management Utility and Manual If any item is found missing or damaged, please contact your local reseller for replacement. Installation The site where you install the hub stack may greatly affect its performance. When installing, consider the following pointers: Install the Switch in a fairly cool and dry place. See Technical Specifications for the acceptable temperature and humidity operating ranges. Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight. 9 Leave at least 10cm (4 in.) of space at the front and rear of the hub for ventilation. Install the Switch on a sturdy, level surface that can support its weight, or in an EIA standard-size equipment rack. For information on rack installation, see the next section, titled Rack Mounting. When installing the Switch on a level surface, attach the rubber feet to the bottom of each device. The rubber feet cushion the hub and protect the hub case from scratching. Installing the Switch on a Desktop When installing the Switch on a desktop or shelf, the rubber feet included with the Switch should first be attached. Attach these cushioning feet on the bottom at each corner of the device. Allow enough ventilation space between the Switch and any other objects in the vicinity. Figure 1. Installed on a Desktop 10 Installing the Switch on a Rack The Switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring closet with other equipment. Attach the mounting brackets at the Switch's front panel (one on each side), and secure them with the provided screws. Figure 2. Combine the Switch with the provided screws. Then, use screws provided with the equipment rack to mount each switch in the rack. 11 Figure 3. Mount the Switch in the rack. Connecting Network Cables The Switch supports 24 10/100BASE-TX Fast Ethernet PoE enabled ports and 2 1000BASE-T/mini-GBIC combo ports. These 24 PoE ports will be automatically activated when a compatible terminal is identified. The Switch will supply power through the PoE port to the connected PD. For Legacy devices that are not yet compatible, the PoE port will not offer the power to these devices. This feature allows users to freely and safely mix legacy and Power over Ethernet compatible devices on their network. The Switch supports 10Mbps Ethernet or 100Mbps Fast Ethernet and it runs both in half- and full- duplex mode using two pairs of Category 5 cables. The Switch also supports 2 1000BASE-T/mini-GBIC combo Gigabit Ethernet ports. When using the RJ-45 ports, it runs in Autonegotiation mode with 10/100Mbps that runs in both half- and full-duplex mode and 1000Mbps that runs in full-duplex mode using four pair Category 5. When using the mini-GBIC ports, it runs in optional 1000BASE-SX/LX fiber connectivity with miniGBIC transceiver module. The Combo Gigabit Ethernet port will run only one of the mini-GBIC ports or RJ-45 ports The mini-GBIC port priority is higher than the RJ-45 port, therefore if both the mini-GBIC port and RJ-45 port are connected, then only the miniGBIC will activate. 12 These RJ-45 ports are Auto-MDI type ports. The Switch can auto transform to MDI-II or MDI-X type, so you can just make an easy connection without worrying if you are using a standard or crossover RJ-45 cable. Figure 4. Connecting Network Cables AC Power The Switch uses the AC power supply 100-240V AC, 50-60 Hz. The power switch is located at the rear of the unit adjacent to the AC power connector and the system fan. The Switch's power supply will adjust to the local power source automatically 13 andmay be turned on without having any or all LAN segment cables connected. 14 IDENTIFYING EXTERNAL COMPONENTS This chapter describes the front panel, rear panel, and LED indicators of the Switch. Front Panel The figure below shows the front panels of the Switch. Figure 5. Front panel view LED Indicator: Comprehensive LED indicators display the status of the Switch and the network (see the LED Indicators chapter below). 10/100Mbps PoE Ports (Port 1~24): These ports are PoE enable ports. These PoE ports will be automatically activated when a compatible terminal is identified, and the PoE port will supply power to the connected PoE device. The Switch PoE function supports PoE ports priority management. When there is a system power shortage with the PD, the Switch will enforce the PoE port priority management; the lower port number will have the higher priority than the higher port number, Port 1 > Port 2 > ... > Port 24. 15 For legacy devices that are not yet compatible, the PoE port will not offer the power to these devices. This feature allows users to freely and safely mix legacy and Power over Ethernet compatible devices on their network. These ports support network speeds of either 10Mbps or 100Mbps, and can operate in half- and full-duplex transfer modes. These ports also support the automatic MDI/MDIX crossover detection function, providing true "plug and play" capability. Just plug-in the network cable to the hub directly and regardless if the end node is a NIC (Network Interface Card) or switch and hub. 1000BASE-T Gigabit Ethernet Ports (Port 25~26): The Switch is equipped with two Gigabit twisted pair ports, supported auto negotiable 10/100/1000Mbps and auto MDI/MDIX crossover detection function. These two ports can operate in half-duplex mode for 10/100Mbps and full-duplex mode for 10/100/1000Mbps. Note: When the port is set to "Forced Mode", the Auto MDI/MDIX will be disabled. mini-GBIC Ports (Port 25F~26F): The Switch is equipped with two mini-GBIC ports, which supports optional 1000BASE-SX/LX mini-GBIC modules. Note: Port 25 and 26 are the same ports with the mini-GBIC Port 25F and 26F ports, when plug in the mini-GBIC module, the device will activate mini-GBIC, and the RJ-45 port will be disabled. 16 Reset: The Reset button is to reset all settings back to the factory defaults. Note: Be sure that you record the settings of your device, or else all settings will be erased when pressing the "Reset" button. Rear Panel Figure 6.

Configuring the Switch The DES-1526 has a Web GUI interface for smart switch configuration. The Switch can be configured through the Web browser. A network administrator can manage, control, and monitor the Switch from the local LAN. This section indicates how to configure the Switch to enable its smart functions including: Port Settings VLAN Settings, Trunk Settings, Port Mirroring, SNMP Settings, PoE Settings, Status, Statistics, System Settings, Trap Settings, Password Settings, Backup Settings, and Reset Settings. 31 Login Before you configure this device, note that when the Web Smart Switch is configured through an Ethernet connection, make sure the manager PC must be set on same the IP network. For example, when the default IP address of the Web Smart Switch is 192.168.0.1, then the manager PC should be set at 192.168.0.x (where x is a number between 2 and 254), and the default subnet mask is 255.255.255.0. Open the Web browser program and Enter IP address http://192.168.0.1 (the factory-default IP address setting) to the address location. Figure 14. Or through the Web Management Utility, you do not need to remember the IP Address, select the device shown in the Monitor List of the Web Management Utility to settle the device on the Web browser. When the following dialog page appears, enter the default password "admin" and press Login to enter the main configuration window. 32 Figure 15 After entering the password, the main page appears, and the screen will display the device status. Figure 16 33 Setup Menu When the main page appears, the Setup menu is on the left side of the screen (Figure 17). Click on the setup item that you want to configure. There are eleven options: Port Settings, VLAN Settings, Trunk Settings, Mirror Settings, SNMP Settings, PoE Settings, Device Status, Statistics, System Settings, Trap Settings, Password Settings, Backup Settings, and Reset Settings as shown in the Main Menu screen. 34 Figure 17. Setup menu Configuring Setup Setting There are six items, including Port Settings, VLAN Settings, Trunk Settings, Mirror Settings, SNMP Settings, and PoE Settings in Setup menu. Port Settings In the Port Settings menu (Figure 18), this page will display each port's status. Press the ID parameter to set each port's Speed, Flow Control, QoS and Link Status. When you need to renew the posted information, press the "Refresh" button. The Link Status in the screen will display the connection speed and duplex mode; otherwise this dialog box will display down when the port is disconnected. 35 Figure 18. Port Configuration To change the port setting, click on the ID parameter to enter the selected port to configure its Speed/Disable and Flow control. Figure 19. Port Settings. 36 Speed/Disable: This setting has six modes--100M Full, 100M Half, 10M Full, 10M Half, Auto, and Disable--for speed or port disable selections. Flow Control: This setting determines whether or not the Switch will be handling flow control. Set FlowCtrl to Enable for avoiding data transfer overflow. If it is set to Disable, there is either no flow control or other hardware/software management. When the 10/100M port is set to full-duplex mode, then the flow control will be automatically set to disable; and if the 10/100M port is set to half-duplex mode, the flow control will be automatically set to enable. QoS: In some ports that need to have a high priority to manage the data transfer, QoS should be changed. Set the port's QoS to high to determine the port will always transfer their data first. 802.1Q VLAN Settings (Virtual Local Area Network) A VLAN is a collection of switch ports that make up a single broadcast domain. You can configure a VLAN for a single switch, or for multiple switches. When you create a VLAN, you can control traffic flow and ease the administration of moves, adds, and changes on the network, by eliminating the need to change physical cabling. On VLAN settings, there are two main settings, VID Table Setting and Port VLAN Setting. VID: Select the VID group that you set. 37 When you select VID Table Setting, press "Add new VID" to create new VID group, from port 01 ~ port 26 (26F), select Untag Port, Tag Port, or Not Member for each port. To save the VID group, press the "Apply" button. To remove the selected VID group, select the VID group and press "Remove the VID" button. To modify the VID group setting, select the VID group and change the setting, and press the "Apply" button to save the settings. Figure 20. VLAN Settings 38 When you select Port VLAN setting, fill in each port's PVID value between 1 and 4094. Figure 21. 39 Trunk Setting The Trunk function enables you to cascade two or more devices with larger bandwidths. There are four Trunking groups to be set; and there are default ports in each member. Checked "Enable" to use the trunk function, select the ports in each member to be trunk, and click "Apply" to activate the selected trunk group. Figure 22. Trunk Settings Be sure that the selected trunk setting port is connected to the device with a same VLAN group. 40 Mirror Setting Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or outgoing packet from one port of a network switch to another port where the packet can be studied. It enables the manager to keep close track of switch performance and alter it if necessary. Configuring the port mirroring by assigning a source port from which to copy all packets and a sniffer port where those packets will be sent. The selections of the sniffer mode are as follows: TX (transmit) mode: This mode will duplicate the data transmitted from the source port and forward it to the sniffer port. RX (receive) mode: This mode will duplicate the data sent to the source and forward it to the sniffer port. Both (transmit and receive) mode: This mode will duplicate both the data transmitted from and data sent to the source port, and then it will forward the data to the sniffer port. 41 Figure 23. Mirror Setting. SNMP Setting Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers, switches, and other network devices. Use SNMP to configure system features for proper operation, monitor performance and detect potential problems in the Switch, switch group, or network. Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage the device. These objects are defined in a Management Information Base (MIB), which provides a standard presentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the network. The DES-1526 supports the SNMP versions 1. In SNMP v.1, user authentication is accomplished using 'community strings', which function like passwords. The remote user SNMP application and the Switch SNMP must use the same community string. SNMP packets from any station that has not been authenticated are ignored (dropped). The default community strings for the Switch used for SNMP v.1 management access are: 42
