Lead one end of the working and protection power cables to the power ports of the CRPC/ROP frame. Route the other
end of the power cables along the cable routing area on the right side of the cabinet to the power cable terminal socket
on the top of the cabinet.
Plug the cord end terminal of the power cable directly, from up to down, into the tributary power output terminal socket.
Tighten the screw to secure the cable.
Plug one end of the crossover network cable into the LAN port on the CRPC/ROP board. Plug the other end to the ETH1
or ETH2 port on the AUX board in the corresponding subrack. If two CRPC/ROP frames are required, the network cables
to the second CRPC/ROP are connected to the ETH1 or ETH2 port in the last slave subrack of the NE.
NOTE
When the master and slave subracks are connected in ringlike structure, connect one CRPC/ROP board to the
ETH3 port in the master subrack using a cable and another to the ETH3 port in the slave subrack using a cable.
