5. Connect the free end of the I/O Cable Assembly to its respective I/O termination assembly. Perform
the appropriate procedure depending on cable type:
For Interconnect I/O Cable Assembly (P2 installed)
1) Connect cable connector P2 (Figure 2-6) to the J1 connector on the Marshalled Termination
Assembly (Figure 1-1). An alignment pin projecting from the face of J1 ensures a correct mating.
2) Press P2 firmly onto J1.
3) Torque the securing screw on the top of P2’s connector shell to 50 inch-pounds maximum.
For Unterminated I/O Cable Assembly (P2 not installed)
Refer to Table 2–2in Subsection 2.8 for the color code and function of each unterminated I/O
wire. Refer to the wiring diagrams for your system to determine where to make the proper cable
connections to the termination assembly.
6. For redundant CAIs, connect the redundant I/O Cable Assembly as described above in step 5.
2.6 CAI Installation
Modules are shipped individually packaged in protective, sealed, static shielding bags. Refer to section
2.4.6 for module handling considerations.
Each slot and each module must be keyed to prevent accidental installation of a module into an
incompatible slot, which may impair system performance. Module and rack keying is highly
recommended; see Figure 2–7.
Modules are keyed at the factory. The keying pattern is unique to each module type (e.g. CCM, CAI,
CDM, CDO).
A factory-assembled rack is keyed at the factory. If you are assembling the rack on site, you must
key each slot according to the module type assigned to it. The slot keying pattern complements the
module’s keying pattern. Stop plugs are supplied with the rack.
Before adding a module to a rack, be sure to key its slot.
Section 2.6.1 describes keying a slot. Section 2.6.2describes installing the module in the rack.
