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.
You can shut down the chassis in one of two ways:
• Perform a graceful shutdown using the shutdown commands. This may take several minutes to complete.
Then toggle the power switch to the OFF position. The power LED changes from solid green to off
immediately.
• Toggle the power switch to the OFF position. The power LED changes from solid green to off.
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.

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.
