viii About This Guide
WARNING: To reduce the risk of personal injury from electrical shock and
hazardous energy levels, do not exceed the level of repair 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 could create conditions
that are hazardous.
WARNING: To reduce the risk of electric shock or damage to the equipment:
■ If the system has multiple power supplies, 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.
