Technician Notes

WARNING: Only authorized technicians trained by Compaq should
attempt to repair this equipment. All troubleshooting and repair proce-
dures are detailed to allow only subassembly/module level repair. Be-
cause 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. Any indications of component replacement or printed
wiring board modifications may void any warranty.
CAUTION: To properly ventilate your system, you must provide a
minimum of 30 inches (76.2 cm) of clearance at the back and 25 inches
(63.5 cm) of clearance at the front of the rack.
CAUTION: The computer is designed to be electrically grounded.
To ensure proper operation, plug the AC power cord into a properly
grounded AC outlet only.
