Maintaining Power Supplies
To verify that the power system is functioning normally, perform
the following procedures regularly:
Check the LEDs on the faceplate of both power supplies. A power supply
is functioning correctly when the green LED labeled
CB ON
is lit steadily
(indicating that the circuit breaker is switched on) and the blue LED labeled
OUTPUT OK
is lit steadily (indicating that the supply is receiving power from
the DC source).
If these LEDs are blinking or other LEDs are lit, there could be an error
condition. For a summary of LED states, see “Power Supply” on page 36.
Issue the following CLI command to check the status of the power supplies.
The following example specifies a slot number (
0
), which is optional. As shown
in the sample output, the value
Online
in the
State
column indicates that the
power supply is operating normally:
