power cord to remove power from the server. Pressing the Power On/Standby button does not shut off
system power completely. Portions of the power supply and some internal circuitry remain active until

power supply. This device protects the hardware from damage caused by power surges and voltage
spikes and keeps the system in operation during a power failure.

Powering down the server
Before powering down the server for any upgrade or maintenance procedures, perform a backup of critical
server data and programs.
