Applying Power to the HP Server
Powering-Up the HP Server
NOTE Turn on power to the monitor connected to the HP Server before you power-on the HP
Server. This allows proper auto-configuration of video output of the Server as it boots up.
CAUTION To prevent damage to the power supply, check the Input Voltage selector switch before
connecting the Server and its power cord to a voltage source.
1. Ensure the Input Voltage selector switch is set for the correct input voltage, before connecting the power
cord to a voltage source. See Figure 2-4.
(Switch shown in
115 volts position.)

2. Ensure the HP Server's power cord is connected to the power source. See Figure 2-4.
3. Press the Power button on the lower front bezel. See Figure 2-1.
When you press the power button on the front bezel, the Server powers up and loads the operating
system. The system runs a set of Power On Self Tests (POST) during this process. For details refer to
Chapter 8, "Configuring the HP Server" and Chapter 9, "Troubleshooting."
Powering-Down the HP Server
1. Log off all users and if necessary, back up files.
o Schedule the power down for a time when the fewest users will be affected by the Server's
downtime.
o If you will be doing any kind of hardware or software upgrade, be sure your Server's data has been
backed up.
2. Follow instructions in your network operating system (NOS) documentation to gracefully shut down all
networking software and applications.
3. Press the power switch on the HP Server's control panel when prompted by the operating system.
Normally this completes the power down procedure.
