Run all cable before attaching the RJ-45 connectors to the Base
Stations. Label both the demarcation block end and the Base Station
end of each wire with the Base Station number using a wire tie marker
or other form of marker.
Remove bridge taps, multiples, or “Y” connections to the Base
Station wires; these will cause data transmission errors. When
using IDFs be sure that the total wire length from the MCU to each
Base Station does not exceed 6,000 cable feet.
The area above some suspended ceilings is used as an
environmental air plenum. The NEC requires that wire that is
installed in plenums be rated for plenum installation.
Terminate Cables at Base Station Locations
Terminate cable at the Base Station using an RJ-45 modular crimp-on
plug.
To avoid damage to the connectors or crimps, be sure to run the
wire to the Base Station before connecting the RJ-45 connectors.
After running the wire to the Base Station location, terminate the wire
using an RJ-45 modular crimp-on plug. Connect the data pair to pins
1 and 2 and the power pair to pins 7 and 8. These connections are not
polarity sensitive.
