3 Removal and replacement procedures

You need the following items for some procedures:
•
Torx T-15 tool
•
Flathead screwdriver
•
Diagnostics Utility on the HP SmartStart CD

Safety considerations

Before performing service procedures, review the following safety information.

Electrostatic discharge

A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper packaging and
grounding techniques are necessary precautions to prevent damage. To prevent electrostatic damage:
•
Transport products in static-safe containers such as conductive tubes, bags, or boxes.
•
Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
•
Cover workstations with approved static-dissipating material. Use a wrist strap connected to the work surface
and properly grounded (earthed) tools and equipment.
•
Keep work area free of nonconductive materials such as ordinary plastic assembly aids and foam packing.
•
Be sure that you are properly grounded (earthed) when touching a static-sensitive component or assembly.
•
Avoid touching pins, leads, or circuitry.
•
Use nonconductive field service tools.

Server warnings and cautions

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:
•
•
•
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.

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.
All manuals and user guides at all-guides.com
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.
