2-2 Service Preliminaries

Preliminary Warnings and Cautions

The following should be noted when operating or servicing the Compaq Professional
Workstation AP200:
IMPORTANT: Any indications of component replacement or printed wiring board
modifications may void any warranty.
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 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 AP200
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.
CAUTION: The workstation is designed to be electrically grounded. To ensure
proper operation, plug the AC power cord into a properly grounded AC outlet only.
