Fast Ethernet Switching System User's Guide Installing Modules The process for installing both optional modules is the same. You cannot change the position of the CPU module. The DES-5024 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 two optional modules available for the DES-5024 are: a 2-Port 100BASEFX (fiber optic) module and a 1-Port 1000BASE-SX (gigabit) module. As shown in Figure 7, optional modules can only be installed in Slot 3. Nothing can be installed in slot 4. The procedure for installing modules is the same for all both modules. Follow these steps to install an optional module: 1. Power the DES-5024 off before installing the optional module. The optional modules are not hot swappable. 2. Remove the blank bracket, as shown in Figure 7, and set aside. Grasp the thumbscrews on the sides of the blank bracket and turn counterclockwise to unscrew them. You can also use a Phillips screwdriver to unscrew the blank bracket. Do not discard the blank bracket. Put the blank bracket back in if you remove the optional module. 3. Install the optional module by inserting it into the guide, see Figure 8, and sliding it in until it stops. Press in firmly until you feel the optional module snap into place. The optional module should be level and flush with the rest of the DES-5024. Never force, twist or bend the module. The optional module slides in smoothly. 4. Gently push the thumbscrews in and turn clockwise to tighten. Do not over tighten the thumbscrews. 5. Power the DES-5024 on after you have installed the optional module. The DES-5024 will auto detect the optional module. 6. Remove the dust cover from the transceiver and plug the cable in. 7. Check the LEDs to verify that there is a link and a proper connection at the port. See the Troubleshooting section if the optional module is not working properly. Installing the DES-5024 14
