Zone 0:
Capacity: 4100 W (maximum 4100 W)
Allocated power: 1255 W (2845 W remaining)
Actual usage: 798 W
Zone 1:
Capacity: 1700 W (maximum 4100 W)
Allocated power: 1090 W (610 W remaining)
Actual usage: 741 W
Total system capacity: 5800 W (maximum 8200 W)

The output of the show chassis power command shows that; on PEM 0 two AC input feeds are expected
and two AC input feeds are connected and on PEM 1 one AC input feed is expected and two AC input
feeds are connected.
2. Issue the show chassis alarms command to see if there are any active alarms and the position of the
PEM DIP switch.
> show chassis alarms
1 alarms currently active
Alarm time Class Description
2017-01-23 05:05:17 PST Minor PEM 1 Dipswitch 0 Feed Connection 2
The output of the show chassis alarms command shows one active alarm on PEM 1 and the position
of the DIP switch as 0.
In this example output, there is an alarm on PEM 1 because there is a need of only one AC feed but
the PEM 1 is connected with two AC feeds and the DIP switch position is 0.
