This switch has double supervisor engines. I tried commands no power enable module x and hw-module module x shutdown for test the second supervisor, but it doesn't work.

How can i test?

    Are you trying to power off a supervisor? What are you actually trying to test? A show redundancy will show states, code versions, modes of operation, and other details. If you want to verify operation, a redundancy force-switchover will force the failover. There is no need to power off a supervisor to test the second one.

    Ensure that you try the command no power enable module x under configuration mode.

Are you using CatOS by any chance? From Cisco Catalyst-6500's power management page Use of the CLI to Power Modules Up or Down You can issue one of these commands in order to power down a properly working module from the command-line interface (CLI):

Catalyst OS (CatOS)— set module power down module_number

Cisco IOS® Software— no power enable module slot

  • i use the IOS and i don't have any chance using CatOS thank you the comments :)
