high-capacity AC power supplies are set to the correct position. Here are examples of
the command output:
user@host>show chassis power
PEM 0:
State: Online
AC input: OK (2 feed expected, 2 feed connected)
Capacity: 4100 W (maximum 4100 W)
DC output: 855 W (zone 0, 15 A at 57 V, 20% of capacity)
PEM 1:
State: Online
AC input: OK (1 feed expected, 1 feed connected)
Capacity: 1700 W (maximum 4100 W)
DC output: 969 W (zone 1, 17 A at 57 V, 57% of capacity)
In Example 1, is running at full capacity (4100 W) with two AC feeds expected and
PEM 0
two AC feeds connected. This indicates that the DIP switch is properly set to
since two AC feeds are connected. The example also shows that

indicates that the DIP switch is correctly set to
Example 2 shows the show chassis power

AC input: OK (2 feed expected, 2 feed connected)
Capacity: 4100 W (maximum 4100 W)
DC output: 0 W (zone 0, 0 A at 56 V, 0% of capacity)
PEM 1:
State: Present
AC input: Check (2 feed expected, 1 feed connected)
Capacity: 1700 W (maximum 4100 W)
The status indicates the system is

connected to the power supplies and the DIP switch is set to position 1.
