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.

1.
Back up your server data.
2.
Shut down the operating system in an orderly manner as directed in your
operating system instructions.

Power down the server and remove the power cord(s).
WARNING:
Before removing the server top panel, ensure that

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

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

with multiple power supplies, you must disconnect
all
the power cords to
completely remove power from the system.
