Displaying PCG Failure Alarms
To check the PCG LEDs, look on the PCG faceplate at the rear of the M40e or M160
router chassis. Table 126 on page 599 describes the PCG LED states. If the blue
MASTER LED on the PCG faceplate is on steadily, the PCG is functioning as master.
The Packet Forwarding Engine current clock source is the master PCG.
To display the PCG master from the Packet Forwarding Engine clock source output,
use the following CLI command:
user@host> show chassis clocks
user@host> show chassis clocks
PFE clock status:

The command output shows that the PCG in slot 0 is the primary clock source or
master.
To display the current PCG alarms, use the following CLI command:
user@host> show chassis alarms
