5. Figure 27 below, illustrates the connections of the drop cable to the connector
blocks inside the Junction Box. Figure 28 shows the order of wire insertion to
ensure that the cables fit in the junction box. When connecting the thick stranded
wire ensure that the screws are fully undone and the hole fully opened to allow the
wire to be inserted without displacing strands. A wire loop should be inserted
between tags 3 & 4.
6. Run and connect the cable from the RJ45 to the Junction Box. The TX and RX
wires are connected to the same Tags as the wires from the CRU. Run and connect
the cable from the PSU to the Junction Box.
7. When wiring is complete re-insert the circuit board into the box and secure the
cables with tie wraps.
