POWER Switch
Use the POWER switch to turn on/off the server.
Power On
Press the POWER switch on the front of the computer chassis.
The POWER lamp lights in green.
IMPORTANT:
If the power cord is connected to a power control device such as a
UPS (Uninterruptive Power Supply), make sure that the power
control device is powered.
The server management logic on your system board monitors and
logs system voltage changes. When plugging the power cord to the
system, you may experience 10 seconds delay from the time you
press the POWER switch on the front panel. This is normal system
operation and is required by the server management logic.
Do not turn off the server until characters following the "NEC" logo
appears on the screen.
