Alarm time Class Description 2013-01-11 14:48:26 UTC Minor PEM 0 Dipswitch 0
Feed Connection 2
3. If the show chassis alarms output shows an alarm on Dipswitch, issue the show chassis power command
to check the DIP switch position.
# run show chassis power
PEM 0:
State: Online
AC input: OK (1 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)
In this example, the DIP switch is in the wrong position since there is one AC feed expected but two
AC feeds are connected. Change the DIP switch to position 1. This should clear the alarm.
NOTE: Changing the DIP switch position does not impact traffic. However, it is always
recommended to do so in a maintenance window.
