To install the CMA and crossbar:

1. Facing the rear of the rack cabinet, grasp the CMA bracket assembly so that arrows by embossed letters point upward and

are visible to you, then fully extend the CMA bracket with the front end in your right hand.

2. Route the front end of the CMA bracket assembly in your right hand along the chassis guide bracket until it clips to the

CMA A bracket you previously attached to the storage enclosure chassis.

3. Using your right hand, push the storage enclosure slightly forward to gain better access to the CMA B bracket.

4. Route the portion of the CMA bracket assembly in your left hand inward until it clips to the CMA B bracket that you

previously installed on the outer rail.
