Step 56 : Make sure the CMA(s) is in operational position by folding the arm(s) in toward the enclosure and
attaching the elbow end(s) to the connector(s) attached to the rail. Verify that all of the cabling is
in functional order and does not bind or catch.
3.10   Special Considerations for Cable Routing
There are a number of special considerations installers should take when routing cables through the CMA.
This section outlines those considerations.
The distance from the end of the connector at the port to the first basket on the CMA should be 20" – 21"
long. This will give the cables enough slack at this end to prevent stress on the port and binding during
operation cycles.

The cables at the port side of the CMA should crisscross in front of the IOMs. To accomplish this, the cables
connected to the ports for IOM B (right hand side when facing the rear) should be connected to the upper
CMA, and the cables connected to the ports for IOM A (left hand side when facing the rear) should be
connected to the lower CMA.
