termination points for the coaxial antenna cable, fiber optic cable, ground cable, and AC cable. The cabinet has inbuilt AC power surge protection and limited storage for fiber optic cables.
1.6.1MountingThe RAN cabinet may be mounted on a wood pole or on a concrete pad. Mounting bracket kits (available from ADC) are required for each type of installation.
1.6.2Fiber Optic Cable EntryA nylon connector is provided on the rear of the RAN cabinet for routing a fiber optic cable into the cabinet. The cord connector provides cable strain relief and a watertight seal at the fiber optic cable entry point. As the connector nut is tightened, a soft neoprene bushing compresses to tightly grip the cable without applying excessive force to the fibers. The connector accommodates cables of a diameter in the range .38 to .50 inches (.97 to 1.27 cm).
Note: If the installer has a larger cable, the manufacturer (Hubbell Inc.) makes bushings
that fit this connector in the following size

The NXD RAN uses 240 VAC power. A one inch (2.54 cm), 90 degree rigid elbow conduit fitting is provided on the rear of the cabinet. The conduit should be routed to an external junction box (not provided). It is suggested that an external AC outlet (not provided) be installed near the cabinet to power test equipment and power tools. The AC source should supply 50/60 Hz,
Ventilation openings are provided in the front door of the RAN cabinet to permit entry of air for cooling. A filter removes dirt particles so that only clean air enters the cabinet. The heated air exits the cabinet through the rear side. The four PAAs are each equipped with three cooling fans that pull air through the module and exhaust it to the rear of the cabinet. A fan assembly at the top of the RAN chassis forces the air out the rear side of the cabinet.
