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.
Warning
Graceful Shutdown of the Chassis
You can gracefully shut down the chassis from either the CLI or Chassis Manager.
See the FXOS Configuration Guide for the procedure to shut down the chassis from the CLI. The graceful
shutdown usually takes as little as a few seconds to as long as three minutes. When the System Halted
message appears, you can move the power switch on the rear of the chassis to OFF.
See Powering Off the FXOS Chassis for the procedure to shut down the chassis from the Chassis Manager.
After the shutdown is completed, you can move the power switch on the rear of the chassis to OFF.
When you shut down the chassis, the security modules are automatically shut down.
Graceful Shutdown of the Security Modules
You can shut down the security modules individually from the CLI, the Chassis Manager, or you can
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.
Shut the security modules down individually when you are replacing a security module.
You must push the power button on every security module installed in the 9300 chassis. You can have
up to 3 security modules installed in the chassis.
Note
See the FXOS Configuration Guide for the procedure to shut down the security modules gracefully using
CLI commands from the Supervisor. When you see Oper Power: off for all slots, you can move the
power switch on the rear of the chassis to OFF.
See Powering On/Off a Security Module/Engine for the procedure to shut down the security module
from the Chassis Manager. After the shutdown is complete, you can move the power switch on the rear
of the chassis to OFF.
The shutdown commands are first available in Firepower FXOS version 2.0.1. See the FXOS Configuration
Guide for more information on using these commands.
Note
Deployment Options
Here are some examples of how you can deploy the Firepower 9300:
• At the core/aggregation layer of a three-tier data center in a high availability configuration.
• As a dedicated multifunction security service within converged infrastructure stacks (vBlock, FlexPod,
for example) at the access layer.
