Warnings and cautions
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 or damage to the equipment, be sure that:
• The leveling feet are extended to the floor.
• The full weight of the rack rests on the leveling feet.
• The stabilizing feet are attached to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become unstable if more than one
component is extended for any reason.
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.
