Power Button Shutdown
The FMC runs in two modes:
• Main power mode—Power is supplied to all FMC components and all operating systems can run.
• Standby power mode—Power is supplied only to the service processor and certain components. You can
safely remove power cords from the FMC in this mode.
After you shut down the FMC to standby power, electric current is still present in the chassis. To completely
remove power as directed in some maintenance procedures, you must disconnect all power cords from all
power supplies on the FMC.
Caution
You can shut down the FMC using the front panel Power button or software management. See the system
shutdown procedure in the Firepower Management Center Configuration Guide for your version for the
software procedures.
Step 1 Check the Power LED:
• Amber—The FMC is already in standby mode and you can safely remove power.
• Green—The FMC is in main power mode and you must shut it down before you can safely remove power.
Step 2 Perform a graceful shutdown or a hard shutdown:
To avoid data loss or damage to your operating system, perform a graceful shutdown of the operating system.
Caution
• Graceful shutdown—Press and release the Power button. The operating system performs a graceful shutdown and
the FMC goes into standby mode. The power LED is amber.
