Step 48 : Test for binding in the extension of the arm by gently pulling the enclosure out of the rack,
ensuring the cables extend properly and that the system doesn't bind at all. If it does, examine
the point at which the binding occurred and adjust the seating of cables in the baskets, check
the connections to the rails, and examine the joints of the arm to ensure that they are all
functioning properly.
Step 49 : 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.

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.

ensure it does not get damaged during transport. If the Ultrastar Data60 is instead being
installed where it will operated, skip this step.
