Server warnings and cautions
Before installing a server, be sure that you understand the following warnings and cautions.
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, if applicable ("Extend the server from the rack" on page 25).
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 26).
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 26).
If the rack environment, cabling configuration, or the server location in the rack creates awkward
conditions, remove the server from the rack.
Extend the server from the rack
NOTE: If the optional cable management arm option is installed, you can extend the server
without powering down the server or disconnecting peripheral cables and power cords. These
steps are only necessary with the standard cable management solution.
1. Power down the server (on page 26).
