You can use the following commands on the management controller to check the status of the switch.
# showunhealthy OK - No unhealthy sensors #
An unfavorable output from the showunhealthy command means a hardware fault with that particular component.
# checkpower PSU 0 present status: OK PSU 1 present status: OK #
A power supply output that is not OK from the checkpower command means that there is a problem with that power supply. See Check Power Supply Status LEDs for assistance.
# getfanspeed Fan 0 not present Fan 1 running at rpm 11212 Fan 2 running at rpm 11313 Fan 3 running at rpm 11521 Fan 4 not present #
A stopped or low speed in the output of the getfanspeed command means there is a problem with that particular fan.
If not present is in the output of the getfanspeed command, yet a fan is installed at that particular slot, there is a problem with that fan.
For either condition, check the fan. See Servicing Fans.
# checkboot Switch OK #
If the output of the checkboot command is not OK, there is a problem with the switch chip. Try resetting the switch chip. See Reset the Switch Chip.

Note - If in the output of the env_test command a voltage deviates more than 10% from the provided specification, there is a problem with the respective component.
