Installation

2.6.1 Module Rack Mechanical Keying

1. Get the rack Keying Kit supplied with the rack.
2. Refer to Figure 2-7 and note the rack-keying pattern applicable to the CAI. Also, locate the rack's
top and bottom rails.
3. Press the stop plugs into the appropriate key holes of the top and bottom rails as identified by the
solid dot keying patterns in the figure.
2.6.2

Module Installation

1. Where applicable, refer to your system documentation and note the assigned rack and slot numbers
for the module to be installed.
2. Remove the CAI from its static shielding bag and ensure that the module is keyed. Also, check the
slot to be sure it is keyed. If required, refer to section 2.6.1 for rack keying information.
3. Insert the module in the assigned slot. Use uniform pressure to firmly seat the module in the
backplane and transition board connectors. If the module does not seat properly, check its keying
pattern. A properly seated module has the rear of its bezel flush against the rack's front rails. A
keyed module that is not matched to a slot does not engage the Backplane or transition board
connectors or seat flush against the rack's front rails.
4. As shown in Figure 2–7, pivot open the bezel's pivoting top and bottom handles to expose the slotted
captive mounting screws then secure the module to the top and bottom rails. Close the bezel's
handles when finished.
Do not use the captive mounting screws to seat the module. Damage to
the bezel can result. Properly seat the module before tightening the
captive screws.
