Chapter 1 Overview

The router series supports hot swapping. Thus, you can remove or install FICs when
the router is running without disconnecting the power supply. But before that, you must
first execute the remove slot command; otherwise, unknown errors might occur. When
you replace the removed FICs, you do not need to execute the undo remove slot
command however.
If you execute the remove slot command inadvertently, you can cancel that operation
by using the undo remove slot command.

II. Removing an FIC
Step 1: Place the router with the front panel forward.
Step 2: Remove the cables connected to the FIC.
Step 3: Loosen the captive screws at both sides of the FIC.
Step 4: Push the ejector levers at both sides of the FIC outward, pull the FIC out of the slot
along the guides until disengaging it totally from the slot.
III. Installing an FIC
Step 1: Place the router with the front panel forward.
Step 2: Align the remote edge of the FIC with the slot edge, push it into the slot, push the
ejector levers inward until it presses against the FIC panel (the angles thus formed
between the FIC panel and the levers are the minimum angles).
Step 3: Fix the FIC in the chassis by fastening the captive screws.
Repeat these steps to install all the other FICs.
1.6 Troubleshooting
3Com 5000 Routers LEDs, indicate the state of the module as follows:
After the installation of a SIC/MIM, turn on the power and view the corresponding
LEDs (such as SLOT0, SLOT1 or SLOT2) on the cover of the Router chassis: ON
means that the SIC/MIM is operating normally and OFF means that the Power-On
Self-Test (POST) of the SIC/MIM has failed.
If the installed SIC/MIM is in abnormal state, check that:
z Proper interface cable is used;
z The LEDs on the panel of SIC/MIM are displaying normally (see the section
introducing the SIC/MIM for its LED status and description);
z The SIC/MIM accepts the configuration and works well using the display
command.
