Step 31 : Now that the chassis is installed, test the installation by sliding the enclosure in and out of the
rack a minimum of three times. If the enclosure binds, catches, or displays any incorrect motion
or behavior repeat the installation.
Step 32 : Install the CMA(s).
a. Orient the CMA so that the elbow is on the left hand side.
b. Attach all three of the connectors to the brackets on the rails. There should be one at the
elbow side and two at the other end.
Note: Adjustments of the vertical rack rails may be required to fix any issues that
may occur.
Note: The CMA has two arms, labeled "upper" and "lower." The lower arm should
have the elbow on the left side and be installed first; the upper arm should have
the elbow on the right side and be installed last.
