Preparation Procedures - HP DL380 Generation 4 Maintenance And Service Manual

WARNING: To reduce the risk of electric shock or damage to the equipment:
•
Do not disable the power cord grounding plug. The grounding plug is an important
safety feature.
•
Plug the power cord into a grounded (earthed) electrical outlet that is easily
accessible at all times.
•
Unplug the power cord from the power supply to disconnect power to the equipment.
•
Do not route the power cord where it can be walked on or pinched by items placed
against it. Pay particular attention to the plug, electrical outlet, and the point where
the cord extends from the server.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and
the internal system components to cool before touching them.
CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating
the server in this manner results in improper airflow and improper cooling that can lead to thermal damage.

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 19).
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
(http://www.racksolutions.com/hp).
•
Power down the server (on page 20).
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 20).
If the rack environment, cabling configuration, or the server location in the rack creates awkward
conditions, remove the server from the rack.
