Information
Resetting the management unit is not allowed, and an error message displays if you try to do 
so. Resetting is a soft reboot, including flushing the forwarding tables.
Starting with FTOS version 7.8.1.0, you can run this command directly on the stack standby unit 
(standby master) to reset the standby. You cannot reset any other unit from the standby unit.
