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.
Action
Remove 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.
Using a #1 Phillips screwdriver, unscrew the four screws from
the MDA you want to remove.
Place 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.
When 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.
