Connecting the Primary Nest to Additional Nests

7900-A2-GB20-00
Connections between nests are only made from the primary nest (Nest 1) to each
expansion nest (Nests 2, 3, and 4). Connecting the primary nest to an expansion
nest allows the MTU-M to monitor the nest card termination units in Nests 2, 3,
and 4.
Procedure
To connect the primary nest to each expansion nest:
1. Connect the primary nest and Nest 2 by connecting the nest expansion cable
between J28 (TO 2) on the primary nest to J26 (FROM 1) on Nest 2.
2. Connect the primary nest and Nest 3 by connecting the nest expansion cable
between J29 (TO 3) on the primary nest to J26 (FROM 1) on Nest 3.
3. Connect the primary nest and Nest 4 by connecting the nest expansion cable
between J27 (TO 4) on the primary nest to J26 (FROM 1) on Nest 4.
