2.5.3 Interconnect I/O Cable Installation
An Interconnect I/O Cable (Figure 2-6) is used to connect each CAI to a Marshalled Termination
Assembly. The cable-to-module connector J1 is installed at the slot location of a CAI module. It is
assumed that (as part of the site preparation procedure) all tagged Interconnect I/O Cables have been
routed and pulled into their respective cabinets and they are ready for connection. An Unterminated I/O
Cable is installed similarly at the rack; however, you are to supply the termination hardware (e.g. terminal
blocks or panels) for use in the marshalling cabinet. CAI/SAI Marshalled Termination Assemblies should
already be installed in the marshalling cabinet (see section 2.6.1) and be ready for cable connection.
Refer to Figure 2–6, and the following installation procedure:
1. Note the following on the cable’s molded J1 connector:
The lower face area of J1 has a “pin mounting hole” located above a captive mounting screw.
This hole engages one of the rack panel’s alignment pins.
The top edge of J1 is to rest in the groove of the backplane’s extruded spacer.
2. Consult your system’s documentation and note the MODULNET node address (if applicable), rack
address number (1 to 16), and the slot number assigned to the CAI. Connector J1 is to be installed at
this location.
3. Install connector J1 at its assigned location as follows:
1) Angle the top edge of the molded connector toward the backplane’s extruded spacer and insert its
tip in the spacer’s groove.
2) Slide the connector in the groove until it is vertically and horizontally aligned with the
appropriate pin (slot #).
3) Carefully lower the molded connector and engage the alignment pin with the connector’s pin
mounting hole. Firmly push down to seat the connector on the pin. When the connector is
properly seated, the pin will be flush with or project slightly above the face of the connector.
4) Secure the connector to the rack panel with its captive mounting screw, which is automatically
aligned with its panel-mounting hole.
5) Get two labels from the bag of CAI labels. On each label, record the appropriate numbers noted
in substep 2 above (see Figure 1–1). Attach one label to each the molded connectors (J1 and P2).
4. Key cable connector P2.
Get the P/N 16056-435 Cable Keying Kit. The kit contains keying pins and instructions. Refer to
Figure 2-6 for CAI keying patterns and install the pins as described in the supplied instruction.
