Overview
Power Switch
Note The initial Firepower 9300 AC chassis has no external power switch. You reset the Firepower 9300 using
CLI commands. To physically power cycle the 9300, you must unplug the power cord and then plug the
power cord back in.
Note After removing power from the chassis either by moving the power switch to OFF or unplugging the
power cord, wait at least 10 seconds before turning power back ON.
The Firepower 9300 chassis has a standby power switch at the rear of the chassis. It controls both power
supply modules. You must shut down the software applications gracefully before turning the switch to
OFF.
Warning Turning the switch to OFF turns off the main power to the Supervisor and the security modules regardless
of the software status, which can result in the loss of any data in transit and the corruption of data on the
SSDs. You must shut down the software applications gracefully before turning the switch to OFF.

Graceful Shutdown of the Security Modules

use the power switch on the front of each security module. Push the power button briefly on the front
panel of each security module. When the power button changes to amber, you can move the power switch
on the rear of the chassis to OFF.
