MDS Assembly Installation
NOTE
:
The maximum number of MDS assemblies which can be installed in the RT
Bay is four. The first shelf must be located at the bottom of the bay even if it
is the only shelf provided.
NOTE
:
The growth pattern for the MDS shelves is from the bottom up. Do not
leave any vacant spaces between or below the shelves. Only the first MDS
assembly will have a small space below its bay position.
J1C265AB-1 MDS Assembly Mounting Procedure
Step 1:
Open the carton and inspect the shelf and all its connectors and cable
assemblies for damage or misalignment.
Step 2:
Mount the assembly using its attached hardware to its designated bay
position. Use the alignment pins to position the assembly.
Step 3:
Locate the ground strap attached to each assembly and connect it to the
bay frame as indicated in the Figure 2-5.
NOTE
:
Remove any paint as necessary on the bay frame to ensure a
low-resistance contact.
Step 4: Move the attached shelf cable assemblies forward so that they drape
into the bay frame’s cable duct areas. Leave the connectors in place at
this time for future connection to the Intrabay and Customer Interface
cable assemblies.
NOTE
:
The following connectors on the shelf dangler cables should be
visible in their respective ducts:
