Replacing an MDA 31

Replacing an MDA

This procedure describes how to replace an MDA.

CAUTION

Risk of service loss

You cannot hot-swap an MDA. You must remove the 8672ATME or 8672ATMM module, install the MDA, and then reinstall the module.

Procedure steps

Step Action

1Remove the 8672ATME or the 8672ATMM module from the chassis and lay it on a flat, static-free surface.

For information about removing a module from the chassis, see Ethernet Routing Switch 8600 Installation — Modules, NN46205-304.

2Using a #1 Phillips screwdriver, unscrew the four screws from the MDA you want to remove.

3Place the palm of your hand on top of the MDA, and cup your fingers around the back of the MDA. Lift the MDA enough to loosen it from the mounting posts.

4When the MDA is loosened from the mounting posts, hold the sheet metal by each side and lift the MDA straight up, being careful not to catch the lip of the MDA on the module. Store the MDA in a static-free container for later use.
