Intershelf Junction Panel (JPI300)
To connect the Intershelf Junction Panel:
1. Connect a five-foot RJ-21 cable from the CSC306 or CSC320 System Controller
Card to the corresponding connection on the JPI300.
2. Connect two 12-foot RJ-45 cables from the Expansion Shelf Controllers
(CSC300) to the corresponding shelf on the JPI300. Be sure the RJ-45 cable in
Connector A on the Shelf Controller goes to the A connector on the JPI300, and
that Connector B goes to the B Connector.
4.8. Connect Demarc Block RJ-21 Cables to Interface
Modules
Connect the male RJ-21 connector from the appropriate demarcation block to the
designated RJ-21 connector (A or B) on each Interface Module. Secure the cables using
the keeper. Dress the cables by wire wrapping the cable at the rear of the shelf.
Do not connect these cables to the system controller or the system
controller will be damaged.
