Install chassis to rack
When installing equipment, ensure adequate ventilation is available. Inadequate ventila
-
tion will result in higher than normal operating temperatures and may result in degraded
operation. Additional care must be used when installing in enclosed racks, or when co-lo
-
cated with other equipment that may increase ambient temperatures.
Always ensure the system receives sufficient airflow such that it will operate within the speci
-
fied operating temperature range.
5.2 Connecting the RF Ports
When connecting the QAM/Burst Receiver ports to the HFC network, take note of the following:
When connecting the F-connector on the cable to the RF connector on the CX180F/R
chassis, always use a torque wrench to set the tightness to 15 inch-lbs. Do not simply
hand-tighten the F-connectors. F-connectors that are too loose can cause RF leakage.
F-connectors that are too tight can damage the RF port electronics.
Rear panels and connectors may be hot.
