Step 32 : 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 33 : 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 standard 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.
Note: CMA Lite has one arm, to be installed at the lower position. This arm
should have the elbow on the left side.
