Remove and Replace the Supervisor
You can remove the Firepower 9300 Supervisor while the system is powered on without damage to the Supervisor hardware or system. However, because the supervisor is controlling the entire chassis, including the power system, we recommend that you use the power switch on the rear panel of the chassis to put the system in standby mode. See Supervisor for more information about the Supervisor.
