2-2 Service Preliminaries
Preliminary Warnings and Cautions
The following should be noted when operating or servicing the Compaq Professional Workstation AP500:
WARNING: To reduce the risk of electric shock or damage to the equipment:
■Disconnect power from the system by unplugging all power cords from either the electrical outlet or the Compaq Professional Workstation AP500.
■Do not disable the power cord grounding plug. The ground plug is an important safety feature.
■Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.
WARNING: To reduce the risk of personal injury from hazardous energy levels, only authorized service technicians should attempt to repair this equipment. 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.
CAUTION: The power supply in the Compaq Professional Workstation AP500 has an auxiliary power section. This section is always active as long as the unit is plugged into a live AC outlet. Be sure to turn off the switch and unplug the power cord before performing any service work.
CAUTION: To properly ventilate the system, you must provide at least 6 inches (15 cm) of clearance at the front of the workstation and 3 inches (7.6 cm) at the back.
IMPORTANT: Any indications of component replacement or printed wiring board modifications may void any warranty.
