Monitoring the Power Supply Status
To display the power supply status of a switch:
1. Log into the switch as the admin user.
2. Enter the psshow command at the command line. The possible values for
power supply status are:
OK - Power supply present and functioning correctly.
absent - Power supply not present.
faulty - Power supply present but faulty (no power cable, power switch
turned off, fuse blown, or other internal error).
After the status line, a power supply identification line may be shown. If present,
this line contains manufacture date, part numbers, serial numbers, and other
identification information.
The following example displays the power supply status using the psshow
command.
