SDQLCAI-1 Installation

marshalling cabinet. A customer-fabricated panel is typically mounted in a customer-supplied
cabinet. Refer to Figure 2–2 and Figure 2–3 for dimensions of the Utility Panel and Marshalled
Termination Assemblies.
1) Determine the mounting layout for DIN rails, wire ducts, and Marshalled Termination
Assemblies.
2) Drill and tap DIN rail and wire duct mounting holes in the panel. If applicable, refer to
MODULPAC 1000 Installation and Service Instruction (document number
SD39MODULPAC-1) for removal of the Utility Panel.
2. Retrieve the Marshalled Termination Assembly to be mounted, including a sheet of CAI labels (P/N
14205-844) and a Cable Keying Kit (P/N 16056-435). Temporarily set aside the Cable Keying Kit.
1) Consult your system documentation and note the rack address number (1 to16) and slot number
assigned to the CAI. For redundant systems, also note these items for the second CAI to be
connected to this Marshalled Termination Assembly. For rack-to-rack redundant CAIs connected
to a MODULNET, the MODULNET node address (1-63) must also be noted for each rack.
2) Retrieve a CAI label and record the appropriate node, rack, and slot numbers on it (see Figure 1–
1). If redundancy is applicable, record the appropriate numbers on a second CAI label. Save the
remaining labels for the next step.
3. Refer to Figure 1-1 and attach a CAI label on the Marshalled Termination Assembly adjacent to
connector J1. If applicable, attach the redundant CAI’s label adjacent to connector J2.
4. As a safety check, verify that connectors J1 and J2 are factory keyed according to Figure 2–3 and
Figure 2–6.
NOTE
It is important to key the connector on the mating Interconnect I/O Cable
as described in section 2.5.3. Keying is a safety feature for preventing
the improper connection of an Interconnect I/O Cable from another type
of I/O module to a CAI/SAI Marshalled Termination Assembly.
5. Refer to Figure 2–5 for the procedure to mount a Marshalled Termination Assembly to a DIN rail.
