Removing and Replacing an AC PEM
This section contains information on removing and replacing AC PEM modules in the Cisco uBR10012
chassis.
Tip
The AC PEM is operating correctly when its Power LED is on (green). When the Fault LED is on
(yellow), the AC PEM is receiving AC-input power but is not providing power to the system. Verify that
the AC PEM is fully inserted into the power bay and that its captive screws have been tightened. Then
flip the power switch on the AC PEM to the standby position, wait several seconds, and then back to the
ON position. If the Fault LED does not go off and the Power LED does not come on, replace the AC
PEM.

provide power only when you are using the DC PEM modules. Do not use these DC terminal blocks
when you are using the AC PEMs.
If you have previously used this Cisco uBR10012 router with DC PEMs, first verify that these DC
terminal blocks are not currently connected before proceeding with the installation or replacement of the
AC PEMs.
