Step 12 When you turn on the power switch on the AC PEM, the FAULT LED goes off and the POWER LED goes 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. Route the AC power cables 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.

Tip This procedure is rarely needed for normal operations because it requires that you shut down the 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 “Replacing a Redundant AC PEM” section on page 5-22.

Step 1 Remove the front cover.

Step 2 Shut down the system using the following procedure:

a.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.

b.Before you shut down the router, use the copy command to save any configuration changes to NVRAM and, if you wish, to a PC media card. See the Cisco uBR10012 Universal Broadband Router Software Configuration Guide for instructions about using the copy command.

c.Turn the power switch on each AC PEM to the standby position (see Figure 5-23).
