Installation
This chapter describes how to install and remove the Catalyst 2820 modules and how to use the module LEDs to interpret the results of the module power-on self-test (POST). When unpacking the Catalyst 2820 modules, check the contents of the package against the list in "Packing List" in the "Introduction" chapter.
Note
All of the Catalyst 2820 modules are hot-swappable: you can install one without turning off the switch.
Removing a Blank Faceplate
Blank faceplates on the Catalyst 2820 cover the high-speed expansion slots, as shown in Figure 2.1.

To remove a faceplate, follow these steps:

Installing a Module
After the faceplate has been removed, follow these steps to install a module in an empty Catalyst 2820 high-speed expansion slot:
Warning
Step 1 Slide the module into the slot card-guides until you feel the card touch the back of the unit.
Step 2 Push the module firmly until you feel it snap into place. Tighten the thumbscrews on the module faceplate.
When the module is installed correctly, its faceplate is flush with the front of the Catalyst 2820 unit.
Step 3 Attach the cable. If you are attaching a fiber-optic cable, remove the rubber plugs from the fiber-optic port on the module and store the plugs for future use.
Attach the cable for a specific module as follows:
•100BaseFX ST connector
Line up the two small tabs on the cable header with the keyed holes in the fiber-optic connector. Insert the cable into the fiber-optic port and turn it one-quarter turn clockwise.
•MIC connector
For a MIC connector, remove the rubber caps from the cable, and insert the connector in the fiber-optic connector, as shown in Figure 2-3, pushing until it snaps into place.

•100BaseTX and FDDI UTP SAS RJ-45 connector
Insert the cable into the RJ-45 connector on the module as shown in .

Note When interconnecting two Catalyst 2820s using a UTP cable, use a crossover cable.
Removing a Module
Figure 2-5 Installed FDDI Modules
shows a Catalyst 2820 with two FDDI modules installed. To remove a module from a Catalyst 2820 slot, follow these steps:
Step 1 Disconnect the cable from the module port.
•If you are removing a fiber-optic cable from an ST connector, grasp the circular part of the cable header, push it in slightly while turning it one-quarter turn counter-clockwise, then pull the cable from the port.
•If you are removing fiber-optic cable from a MIC connector, press in the locks on the cable header and then pull the cable from the port. Replace the protective cap on the end of the fiber-optic cable and the rubber plugs in the fiber-optic port.
•If you are removing a UTP cable, disconnect it from the RJ-45 connector.
Step 2 Loosen the thumbscrews attaching the module faceplate to the Catalyst 2820.
Step 3 Remove the module by grasping the thumbscrews and pulling the module out of the slot.
Step 4 Replace the blank faceplate to cover the empty expansion slot if you are not replacing the module with another.
POST for FDDI
When first powered on, the expansion slot LED of the Catalyst 2820 and all LEDs on the module front panel are green. A power-on self-test (POST) is automatically started. If the module passes the POST, the expansion slot LED (A or B) on the Catalyst 2820 remains green. If the module fails the POST, the expansion slot LED turns amber.
If an FDDI module fails the POST, the LEDs on the module indicate the type of failure. shows how to use the LEDs to interpret POST failures.
For more information about the A and B expansion slot LEDs, refer to the Catalyst 2820 and Catalyst 1900 User Guide.
Table 2-1 LED Indicators of Failed FDDI POST
POST for 100BaseT Modules
When first powered on, all LEDs on the module front panel are green, and a POST automatically begins. If the module passes POST, the expansion slot LED (A or B) on the Catalyst 2820 remains green. If the module fails POST, the expansion slot LED turns amber.
For a complete description of each LED, see "100BaseT Module LEDs" in the chapter "Introduction."
