Technician Notes
WARNING! Only authorized technicians trained by HP should attempt to repair this equipment. All
troubleshooting and repair procedures are detailed to allow only subassembly/module-level repair. Because of
the complexity of the individual boards and subassemblies, no one should 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 personal injury from electric shock and hazardous energy levels, do not
exceed the level of repairs specified in these procedures. 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 conditions that are hazardous.
WARNING! To reduce the risk of electric shock or damage to the equipment:
• Disconnect power from the system by unplugging all power cords from the power supplies.
• 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.
CAUTION: To properly ventilate the system, you must provide at least 7.6 cm (3.0 in) of clearance at the front
and back of the server.
CAUTION: The computer is designed to be electrically grounded (earthed). To ensure proper operation, plug
the AC power cord into a properly grounded AC outlet only.
NOTE: Any indications of component replacement or printed wiring board modifications may void any
warranty.
