Powering Down the Server
System power in ProLiant DL320 servers does not completely shut off from the front panel
Power On/Off switch. Although switching the server off removes power from most
electronics and the drives, portions of the power supply and some internal circuitry remain
active. To completely remove all power from the system, disconnect all power cords from the
server.
WARNING: To reduce the risk of injury from electric shock, remove the power cord to
completely disconnect power from the system.
WARNING: To reduce the risk of personal injury or damage to the equipment, ensure
that only one component is extended at a time. A rack may become unstable if more
than one component is extended for any reason.
WARNING: Because the rack allows you to stack computer components in a vertical
rather than a horizontal plane, you must take precautions to provide for rack stability
and safety to protect both personnel and property. Heed all cautions and warnings
throughout the installation instructions that came with the server.
WARNING: To reduce the risk of personal injury or damage to the equipment, place the
server on a sturdy table or workbench whenever it is removed from the rack for device
accessibility. Refer to the Compaq ProLiant DL320 Server Setup and Installation Guide
for further information on working with racks.
CAUTION: Moving the Power On/Off switch to the off position does not completely remove
system power. Some portions of the power supply and some internal circuitry remain active.
Disconnect all power cords from the server to remove all power from the system.
CAUTION: Electrostatic discharge can damage electronic components. Be sure you are
properly grounded before beginning any installation procedure. For more information, see
“Electrostatic Discharge Information” in this chapter.
NOTE: Microsoft Windows NT users may use the Compaq Power Down Manager to power down the
server. For information on this system utility, refer to the NTREADME.HLP file on Diskette 1 of the
NTSSD.
