Chapter 4 Operating the Modulator
Inspect the Modulator
Although, the modulator can operate unattended for extended periods. Cisco
recommends that you perform a visual inspection once every 3 months.
Important: Only qualified personnel should maintain and service the MQAM.
Check the following items during a visual inspection:
Cables and connectors—Verify that all cables are mated properly and all
retaining screws are tight. Inspect cables for stress and chafing.
Cover and rear panel—If necessary, clean the cover and rear panel with a soft
cloth dampened with a mild detergent solution.
Fan intakes on side panel—Check the fan intakes on the side panel for excessive
lint or dust buildup. Remove the lint and dust from the intakes using a damp
cloth or a small hand vacuum.
