Removal and replacement procedures
Required tools
You need the following items for some procedures:
•
T-10/T-15 Torx screwdriver (included with the server)
•
HP Insight Diagnostics software (" HP Insight Diagnostics " on page 70 )
Preparation procedures
To access some components and perform certain service procedures, you must perform one or more of the
following procedures:
•
Extend the server from the rack (on page 26 ).
If you are performing service procedures in an HP, Compaq branded, telco, or third-party rack
cabinet, you can use the locking feature of the rack rails to support the server and gain access to
internal components.
For more information about telco rack solutions, refer to the RackSolutions.com website
(

•
Power down the server (on page 25 ).
If you must remove a server from a rack or a non-hot-plug component from a server, power down the
server.
•
Remove the server from the rack (on page 27 ).
If the rack environment, cabling configuration, or the server location in the rack creates awkward
conditions, remove the server from the rack.
•
Access the product rear panel (on page 27 ).
If you are performing certain service procedures, access the product rear panel.
Power down the server
WARNING: To reduce the risk of personal injury, electric shock, or damage to the
equipment, remove the power cord to remove power from the server. The front panel Power
On/Standby button does not completely shut off system power. Portions of the power supply
and some internal circuitry remain active until AC power is removed.
IMPORTANT: If installing a hot-plug device, it is not necessary to power down the server.
1.
Back up the server data.
2.
Shut down the operating system as directed by the operating system documentation.
