ACTION
Clean Air Vents/Check
Fan
30 Days
Inspect and clean per paragraph 5-3.
Verify fans are working properly.
Inspect Cables and
Connectors and General
Site Conditions
6 Months
Inspect signal and power cables for frayed
insulation and proper attachment. Check
RF connectors to make sure that they are
tight. Inspect the lightning protection
system and ground at the site.
5.3 CLEANING AIR INLETS/OUTLETS
The air inlets and outlets should be checked every 30 days and cleaned if necessary. If the
equipment is operated in a severe dust environment, it should be checked and cleaned more often.
If dust and dirt are allowed to accumulate, the cooling efficiency will be diminished. Using either
compressed air or a brush with soft bristles, loosen and remove accumulated dust and dirt from the
air inlet panels.
Check that the fans are running smoothly. A slow running or noisy fan may indicate an imminent
fan failure. Heat is one of the biggest factors in reducing the reliability of the amplifier. Ensure the
fan has access to cool and clean airflow within the rack.
