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.
