env_test Command

Displays environmental status.




This hardware command performs a series of hardware and environmental tests of the switch. This command is an amalgamation of the following commands:

The command output provides voltage and temperature values, pass-fail results, and error messages.


The following example shows how to display the hardware and environmental status of the switch with the env_test command.
