Power Switch
The power switch is located to the left of power supply module 1 on the rear of the chassis. It is a toggle
switch that controls power to the system. If the power switch is in standby position, only the 3.3-V
standby power is enabled from the power supply module and the 12-V main power is OFF. When the
switch is in the ON position, the 12-V main power is turned on and the system boots.
Before you move the power switch to the OFF position, use the shutdown commands so that the system
can perform a graceful shutdown. This may take several minutes to complete. After the graceful shutdown
is complete, the console displays It is safe to power off now. The front panel blue locator
beacon LED lights up indicating the system is ready to be powered off. You can now move the switch
to the OFF position. The front panel PWR LED flashes momentarily and turns off.
See
for more information on using the shutdown commands.
Note
On the Firepower 2130 and 2140, the OK LEDs on the rear power supplies flash after the switch is turned
off; this is expected behavior.
Caution If you move the power switch to the OFF position before the shutdown command sequence is complete
or if you remove the system power cords before the graceful shutdown is complete, disk corruption can
occur.
The two-post grounding lug is
included in the accessory kit.
