7.1.1
Maintenance Overview
This equipment has been designed to give long, trouble-free service with very little maintenance.
Under normal service conditions, the only routine maintenance required is to monitor the air
filter for cleanliness.
This equipment contains static sensitive devices. A grounded wrist strap and
mat should be used when handling the internal circuit cards.
This equipment has been designed so that maintenance operations can be
performed while the equipment is operational (energized and performing
switching functions). Only the power supply assemblies and the AC supply
line circuits contain potentially lethal shock hazards.
7.1.2
Air Filter
The air filter(s) should be checked monthly to ensure that an adequate supply of clean air is
available to cool this equipment. If the air filter is dirty, either clean it with low-pressure air,
vacuuming, or a mild soap-and-water solution (then dry); or replace it with a new air filter
(PESA Part No. 81-9065-2360-0).
