The PEM is on, is receiving power from the AC power source, and is providing

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

power to the Cisco uBR10012 chassis (normal operations).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Fault

Yellow

 

Indicates that AC-input power is being received by the PEM, but that the PEM is

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

not supplying power to the chassis, typically because the PEM’s power switch is

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

turned to the standby position.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

If the Fault LED is lit when the power switch is in the ON position, the PEM is

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

not operating correctly.

Green LED on PEM

1. Make sure the power switch on the PEM is turned to the ON position.

fails to light

2.

Make sure the PEM is properly seated and that its captive screws have been

 

 

 

tightened.

 

3.

Make sure that the AC-input power cord is securely plugged into the power

 

 

plug on the front panel of the PEM. Secure the cord in the clips to ensure

 

 

the plug is not accidentally pulled out.

 

4.

Check the external power source and verify that the AC-input power cord is

 

 

correctly connected to the power outlet.

 

5.

Move the PEM to the other PEM slot. If the PEM still fails, replace it.
