Installing and Removing Line Cards

Removing a Line Card

This section explains how to remove a line card from the AT-8400

chassis. It is a generic procedure that can be used to remove any of the

line cards, with the exception of the AT-8401 management card. To

illustrate the procedure, diagrams of the AT-8411 line card are used.

Before you use this procedure, see Software Implications of Replacing

Line Cards on page 33 for information about preserving your software

configuration when you remove and replace a line card.

Caution

Replace line cards one at a time to avoid a system malfunction.

Note

The Eject button featured on some AT-8400 line cards is not

functional.

For line card removal, perform the following procedure:

1. Select a line card to remove.

Use this procedure to remove a line card from slots one through

twelve.

2. Remove the cables (twisted pair or fiber optic) from the ports on the

line card.

3. Examine the LEDs on the AT-8401 management card. See Figure 18.

If the WAIT/REMOVE LED is steady green, you can safely remove a

line card from the chassis:
