Network module connections

Each multi-group system contains between two and eight Network groups. Group 0 is contained in the Core/Net modules. Groups 1 through 7 are contained in the Network modules. Each Network group is comprised of two Network shelves: Shelf 0 and Shelf 1.

Network Group 0: Shelf 0 to Shelf 1

The Core/Net modules contain Network Group 0: Shelf 0 is in Core/Net 0, Shelf 1 is in Core/Net 1. Shelf 0 must be connected to Shelf 1 for Network Group 0 to operate correctly.

Connecting network Group 0: Shelf 0 to Shelf 1 involves:

1“Connecting the 3PE faceplates in the Core/Net modules” on page 240

2“Connecting the Core/Net backplanes” on page 241

Connecting the 3PE faceplates in the Core/Net modules

The 3PE cards in the Core/Net modules must be directly connected with an NT8D80 cable. See Figure 102 on page 241. This connection is only made between the Group 0 shelves (in the Core/Net modules).

Procedure 38

Connecting the 3PE faceplates in the Core/Net modules

1Connect a NT8D80 cable from the J4 port in the Core/Net 0 3PE card to J4 port in the Core/Net 1 3PE card.

2Connect a second NT8D80 cable from the J3 port in Core/Net 0 to the J3 port in Core/Net 1.

Note: The 3PE cards are located in Core/Net slot 11.
