Table 1 describes the LEDs on the AC PEM.
Air Flow
The AC PEM works together with the fan assembly module to ensure that the Cisco uBR10012 chassis
is properly cooled during normal operation. Figure 3 shows the airflow through the Cisco uBR10012
chassis when dual AC PEMs are installed.
Table 1 AC PEM LEDs and Their Function
LED Color Description
Power Green 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 power switch is in the ON position, the PEM is not operating correctly.
