ARM Shelf Installation
NOTE:
Only one ARM shelf can be installed in the COT Bay. The shelf must be
located at the specific location depicted in the figure even if only one MDS
shelf is provided.
For ease of assembly the Power Interface Unit (PIU) should be mounted on
the ARM shelf before the shelf is mounted to its bay position.
ED7C734-30 PIU Mounting Procedure
Step 1:
Open the cartons to the ARM shelf and the PIU and inspect the contents
especially the connectors and cable assemblies for damage or misalign-
ment.
Step 2:
Refer to Figure 2-6 and mount the PIU to the ARM shelf as follows:
a. Remove the three screws attached to the PIU's hinge captive nuts
(this is the RT version of the PIU).
b. Using two of the three screws provided, through the other screw
holes in the hinge, fasten the PIU hinge to the rear side of the ARM
shelf from the outside of the shelf.
c. Temporarily close the hinged door by finger-tightening the attached
knurled screw head into the ARM shelf's captive nut.
d. Verify that the attached cables drape to the left (rear) and are not
entangled.
