Step 12 When you turn on the power switch on the AC PEM, the Fault LED should go off and the Power LED
should come on (green).
Step 13 Slide the front bezel cover onto the four corner posts of the chassis and then push down, so that the posts
are seated in the grooves above the cover holes. The AC power cables should be routed through the notch
on the right side of the cover.
Replacing Both AC PEMs
Use the following procedure to replace or reinstall both AC PEMs. This procedure is typically needed
only when you need to move the chassis or reinstall it in another location.
This procedure is rarely needed for normal operations because it requires that you shut down the
Tip
Cisco uBR10012 router and remove all power to the system. To avoid this, Cisco recommends replacing
each AC PEM, one at a time, by following the instructions in the
section on page
Step 1 Remove the front cover.

Notify appropriate personnel that you plan to shut down the system and that the shutdown will result
in total loss of service. Appropriate personnel includes the regional alarm or network monitoring
center, central office personnel, and key customers.
Before you shut down the router, use the copy command to save any configuration changes to
NVRAM and, if you wish, to a PCMCIA Flash memory card. See the Cisco uBR10012 Universal
Broadband Router Software Configuration Guide for instructions about using the copy command.
