4.1 Cable Access and Connections
4.1.1 Cable Access
Typical cable access is from an overhead cable tray. Two cable access ports are provided in the top of the cabinet to feed
cable connections into the cabinet. There are two additional cable access ports at the bottom rear of the cabinet to
accommodate cables which are fed from the floor.
4.2 Antenna Connection
The antenna transmission line is normally terminated just inside the entrance to the building at the waveguide port. From the
transmission line termination a short, typically 2’, flexible jumper is used to connect to the lightning surge arrestor and
another flexible jumper is used to connect from the surge arrestor to the NC-2200 duplexer antenna port. The duplexer
antenna port is a Type N female connector.
4.3 Surge Protection
A lightning surge arrestor is required in the antenna feed line for all installations. The surge arrestor should be mounted at the
antenna cable termination just inside the cable entry to the building. The surge arrestor is typically mounted directly to a
ground bus located directly below the waveguide entry ports. A recommended model for the surge arrestor is the Polyphaser
IS-50NX-C1 Coaxial Surge Arrestor.
4.4 Ground Connection
The NC-2200 must be bonded to the building ground electrode system. The vertical Rack Ground Bus in the NC-2200
cabinet must be bonded to the building ground using a #2 AWG green jacketed stranded copper cable.
4.5 Ethernet Connection
The Ethernet connection to equipment cabinet is made to the Uplink port on the 5 port Ethernet switch. Ethernet patch cables
connect the Network Controller computer and Network Power Bar to the Ethernet switch.
4.6 Earthquake Bracing
Some jurisdictions or landlords will require earthquake bracing for the equipment cabinet. Consult with the site owner to see
if this requirement applies. If bracing is required the braces are typically bolted to the top of the cabinet. It will be necessary
to drill holes in the cabinet to attach the bracing.
4.7 FCC RF Exposure Warning
Users and installers must be provided with appropriate antenna installation instructions and transmitter operating conditions,
including antenna co-location requirements of §1.1307(b)(3), for satisfying RF exposure compliance. The antenna used with
this transmitter must not exceed 6 dBd. The antenna should be mounted to provide a separation distance of at least 4 meters
from all persons. Unauthorized antenna installations may violate FCC regulations.
