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 (
Extending the server from the rack
).
If you are performing service procedures in a Hewlett Packard Enterprise, 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, see the Hewlett Packard Enterprise infrastructure
website (
, search for “Infrastructure Services and Solutions”).
• Power off the server (
).
If you must remove a server from a rack or a non-hot-plug component from a server, power off the
server.
• Remove the server from the rack (
Removing the server from the rack
on page 139
).
If the rack environment, cabling configuration, or the server location in the rack creates awkward
conditions, remove the server from the rack.
