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.

The server is unstable when not fastened to the rails.
When mounting the server in a rack, remove the power supplies and any other
•
removable module to reduce the overall weight of the product.
