3.At the rear of the carrier, use a large flat-blade screwdriver to engage and tighten the two captive screws that fasten the CO Power Unit to the carrier.

4.Plug one backplane connector cable assembly from the P20 connector on the carrier's backplane to the P6 connector on the CO Power Unit's backplane. Then, plug the second backplane connector cable assembly from the P19 connector on the carrier's backplane to the P3 connector on the CO Power Unit's backplane. The backplane connector cable assemblies enable a backplane-to-backplaneconnection which provides low voltage dc power to the carrier (see Figure 2-4).
