Compaq ProLiant 5500 Setup And Installation Manual page 68

1. Back up your server data.
2. Shut down the operating system in an orderly manner as directed in your
operating system instructions.
3. Power down the server and remove the power cord(s).
WARNING: Before removing the server top panel, ensure that
the server is turned off and that the power cord is disconnected
from the electrical outlet.
IMPORTANT: The system power in the ProLiant 5500 server does not
completely shut off with the front panel Power On/Standby switch. The two
positions of the switch function as ON and STANDBY, rather than ON and
OFF. The STANDBY position removes power from most of the electronics
and the drives but portions of the power supply and some internal circuitry
remain active. Consequently, to completely remove all power from the
system, you must disconnect the power cord from the server. In systems
with multiple power supplies, you must disconnect all the power cords to
completely remove power from the system.
4. Disconnect any other external equipment connected to the computer.
5. Loosen the two thumbscrews on the front of the unit.
6. Loosen the Torx T-15 screw on the front of the server.
For use with Intel Pentium II Xeon processor-based servers only
