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 off but the power cord is plugged in and
the power supply is flashing green, the system is in standby position, and only the 3.3-V standby power
is enabled from the power supply module. 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. Wait until the front panel
PWR LED flashes momentarily and is off before removing AC power.
See
for more information on using the shutdown commands.
Caution If you remove the system power cords before the graceful shutdown is complete, disk corruption can
occur. You can move the power switch to OFF before the shutdown. The system ignores it.
Note After removing power from the chassis by unplugging the power cord, wait at least 10 seconds before
turning power back ON. You want to keep the system power off, including the standby power, for 10
seconds.
