Preliminary Warnings and Cautions
The following should be noted when operating or servicing the Compaq Professional
Workstation AP400:
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 AP400 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 and back of the workstation.
