Figure 7: Attach Mounting Brackets Installing the DES-5200 14 Fast Ethernet Switching System User's Guide Figure 8: Insert into Rack Installing the DES-5200 15 Fast Ethernet Switching System User's Guide Installing Optional Modules The process for installing all modules is the same. You cannot change the position of the CPU module. It must remain in the CPU slot. The DES-5200 will not work unless the CPU module is installed in the CPU slot. You can purchase optional modules separately in order to meet the needs of your network. The procedure for installing all optional modules is the same for full size and half size modules. Follow these steps to install modules: 1. Power the DES-5200 off before installing or removing modules. None of the modules are hot swappable. Removing or installing modules while the DES-5200 is powered on can damage the DES5200 and the modules. 2. Grasp the thumbscrews on the side of the module or blank bracket and turn counterclockwise to unscrew them. Remove the old module or the blank bracket, as shown in Figure 9 and set aside. Do not discard the module or blank bracket. Put the old module or blank bracket back in if you remove the new module. Install the new module by inserting it into the guides, see Figure 10, and sliding it in until it stops. Press in firmly until you feel the module snap into place. The module should be level and flush with the rest of the DES-5200 Never force, twist or bend the module. The module slides in smoothly. Gently push the thumbscrews in and turn clockwise to tighten. Do not over tighten the thumbscrews. Power the DES-5200 on after the new module is installed. The DES-5200 will auto detect the module and it will appear on the menu. The 100BASE-FX and 1000-BASE-SX ports have dust covers over the transceivers. Remove the dust covers before plugging in the cable. Check the LEDs to verify that there is a link at the port. 3. 4. 5. 6. 7. See the Troubleshooting section if the optional module is not working properly.

Contact D-Link Systems, Inc. for technical support. Check the configuration of the DES-5200 after a power failure but do not reset unless it is necessary. The DES-5200 can be used with power sources in the range 100 to 240 VAC., 50 to 60 Hz. Installing the DES-5200 19 Fast Ethernet Switching System User's Guide 3 Connecting the DES-5200 to the Network This chapter covers the following: · Cable Specifications · Ports · Connecting the DES-5200 to another DES-5200 · Connecting the DES-5200 to other switches and hubs This section deals with making cables and connecting the DES-5200 to other devices. It is extremely important that cables have the correct pin arrangement and that the proper cables be used when connecting to servers, switches, hubs, workstations and other devices. Cable Specifications Use the following guidelines when handling cables: · · Do not stretch or bend cables. Do not put copper cables near sources of electromagnetic interference. Fiber optic cables are immune to most electromagnetic interference. Do not create trip hazards by laying cables in aisles and walkways. Secure cables to the floor when routing in aisles or walkways. · · Do not use telephone cable. Telephone cable does not support Ethernet or Fast Ethernet. Copper Cable In order for Ethernet or Fast Ethernet to work the wires must be arranged correctly inside the RJ-45 connector. The most common problem on Ethernet or Fast Ethernet networks is the cable. If you migrate from Ethernet to Fast Ethernet, make sure the cables are pinned out properly. There are two types of cables: straight through and crossover. Category 3, 4, and 5 UTP/STP cable has eight wires inside the sheath. The wires form four pairs. Straight through cable has the same pin out, inside the RJ-45 connector, at both ends. Crossover cable has a different pin arrangement at each end. Fast Ethernet does not tolerate incorrect pin arrangements. You must use the correct pin arrangement in order for the DES-5200 to work properly. See Figure 11, for an example of straight through and crossover cable. Connecting the DES-5200 to the Network 20 Fast Ethernet Switching System User's Guide The type of cable you use depends on the speed of your network. A network running at 10 Mbps can use lower grade cable than a network running at 100 Mbps. Table 4: Cable Specifications for Copper Connection, shows the cable requirements for Ethernet and Fast Ethernet networks. Table 4: Cable Specifications for Copper Connection Ethernet Type 10BASE-T 100BASE-TX Cable Requirements Category 3, 4, and 5 UTP or STP Category 3, 4, and 5 UTP or STP Maximum Length 100 M (328 ft.) 100 M (328 ft.) Connecting the DES-5200 to the Network 21 Fast Ethernet Switching System User's Guide Figure 11: Cable Diagram Connecting the DES-5200 to the Network 22 Fast Ethernet Switching System User's Guide Fiber Optic Cable Data can travel much farther over fiber optic cable than over Category 3, 4, or 5 cable. Cable length can be up to two kilometers (1.25 miles) in full duplex and 412 meters (1350 feet) in half duplex transmitting at 100 Mbps. Fiber optic cables connected to the fiber expansion module for 100 Mbps must meet the following specifications to carry 1300 nm wavelength for the specified distance: · · Multi-mode cable ISO/IEC 793-2 type B1 and ITU-T G.652 standards Cable must have SC connectors Fiber optic cables attached to the gigabit expansion module must meet the following specifications to carry 850 nm wavelength for the specified distance: · · · · Multi-mode cable ISO/IEC 793-2 type B1 and ITU-T G.652 standards Cable must have SC connectors 62.5 um cable 220 meters (720 feet) 50 um cables 500 meters (1639 feet) Gigabit traffic can travel the following distances using the specified cable: Connecting the DES-5200 to the Network 23 Fast Ethernet Switching System User's Guide Ports MDI-X Ports The ports in the 12-Port 10/100-TX module are MDI-X crossover ports. The pin arrangement is the same as the arrangement in a crossover cable. The advantage of MDI-X ports is that you can connect a device with an MDI-II port without using a crossover cable. The steps for connecting the DES-5200 to 10 Mbps devices or 100 Mbps devices are the same. All the ports will auto negotiate the proper speed and duplex mode. There are two full sized TX modules and one half sized TX module available for the DES-5200. The chassis supports a maximum of 28 10/100-TX ports. Fiber Optic Ports The DES-5200 supports 100BASE-FX and 1000BASE-SX. The chassis supports a maximum of 20 100BASE-FX ports and a maximum of 2 1000BASE-SX ports. There are two 100BASE-FX modules available: a full size 8-Port 100BASE-FX module and a 2-Port 100BASE-FX half size module. The 100BASE-FX ports support full and half duplex at 100 Mbps. The ports do not support 10 Mbps. A half size 1-Port 1000BASE-SX module is available. The 1000BASE-SX module only supports full duplex at 1000 Mbps. Refer to Installing Optional Modules for installation instructions. Refer to Cable Specifications for information on cable types and connectors. Follow these steps to connect cables to the DES-5200: 1. Check for the appropriate cable configuration for each device. 2. 3. 4. Plug one end of the cable into any of the ports.

The DES-5200 can be managed in-band or out-of-band. In-band management refers to managing the DES-5200 through Telnet, using one of the ports. Out-of-band management means going through the RS-232 port. The interface and options are the same with Console and Telnet Management. The difference is the type of connection and the port that is used to manage the DES-5200. Telnet is In-Band Management. D-View is a proprietary SNMP management program. D-View module is provided with the DES-5200. The DES-5200 supports other SNMP management applications and uses standard MIB. Refer to appropriate documentation for installing and using other SNMP application programs. The look and feel of DView is different from other management types. Refer to other documentation if you are using other vendors' SNMP applications. All instructions given in this chapter assume that you are logged into the DES5200 and are at the appropriate panel for carrying them out. Managing the DES-5200 36 Fast Ethernet Switching System User's Guide Console Management Console Management is always done through the RS-232 serial port and requires a direct connection between the DES-5200 and a PC. This type of management is very useful when the network is down and the DES-5200 cannot be reached by any other means. Use Console Management to log into the DES-5200 for the first time. You do not need to know the IP address to log in using Console Management. You can change all the settings and configure the DES-5200, set the IP address and perform other management functions. The management session will timeout after five minutes if you have not taken any action. Press Enter or Control + r to refresh the screen. You will have to log in again after a timeout. Follow these steps to begin a management session using Console Management: 1. Attach the male end of the RS-232 serial cable provided with the DES-5200 to the RS-232 port located at the front of the DES-5200. 2. 3. · · · · · · 4. 5. · · 6.
