3Com Router 5000 and Router 6000 v2.41

Module Guide

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:

Proper interface cable is used;

The LEDs on the panel of SIC/MIM are displaying normally (see the section introducing the SIC/MIM for its LED status and description);

The SIC/MIM accepts the configuration and works well using the display command.
