NOTE:

A screwdriver is required to loosen and tighten the screws securing the ground wire to the ground block.

2.Run the ground wire to an approved ground. Refer to Appendix A.

3.At the Expansion Port Network (EPN) cabinet(s) (as provided), connect a 6 AWG ground wire to the A-cabinet ground block.

4.Run the ground wire from the Expansion Port Network (EPN) to the Processor Port Network (PPN) cabinet and connect it to the cabinet ground block.

NOTE:

If the Expansion Port Network (EPN) cabinet is remotely located from the Processor Port Network (PPN) cabinet (in a separate room or building), run the 6 AWG cabinet ground wire to an approved protective ground.

5.At the Processor Port Network (PPN) cabinet, connect a 10-AWG wire to the cabinet ground block. At a later time, tie-wrap the ground wire (coupled bonding conductor) to the trunk cables, terminating it at the coupled bonding conductor terminal bar at the cross-connect field for the switch. Refer to Figure 4-9 on page 4-13for an illustration of the coupled bonding conductor.
