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 100BASE-
FX (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.
