Server Warnings and Cautions

Preparation Procedures

To access some components and perform certain service procedures, you must do one or
more of the following:
•
Extend the server from the rack.
If you are performing service procedures in an HP, 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:

•
Access internal components.
If you need to access internal components for removal or replacement, you can remove
the access panel without removing the server from the rack.
•
Power down the server.
•
Remove the server from the rack.
If the rack environment, cabling configuration, or the server location in the rack creates
awkward conditions, remove the server from the rack.

WARNING: Do not exceed the level of repair specified in the procedures in the product
documentation. All troubleshooting and repair procedures are detailed to allow only
subassembly or module-level repair. Because of the complexity of the individual
boards and subassemblies, do not attempt to make repairs at the component level or to
make modifications to any printed wiring board. Improper repairs can create a safety
hazard.
WARNING: To reduce the risk of electric shock or damage to the equipment:
•
Do not disable the AC 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 each power supply to disconnect power to the
equipment.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the hot-plug
drives and the internal system components to cool before touching.
CAUTION: Do not operate the server for extended periods without the access panel.
Operating the server without the access panel results in improper airflow and improper cooling
that can lead to thermal damage.
