• Do not route short SAS daisy chain cables through the CMA. Do not route an
excess of cables such that the CMA clamps bow or appear structurally unfit to
support the weight.
• If using two clustered controllers mounted in the middle of the rack with disk
shelves located above and below them, you can divide the disk shelf SAS cables
between the two CMAs so they properly route to the upper and lower disk shelves.
• If later removing the CMA, be sure to support it as you remove the connectors.
1. If the CMA has flat cable covers (for a 1U chassis), install the 2U round cable
covers provided in the accessory kit.
2. To replace the flat cable covers:
a. Remove each flat cable cover by lifting up on the cable cover handle.
b. Open it 180 degrees to the horizontal position.
c. Apply upward pressure to the outside edge of each hinge connector until the
hinge connector comes off the hinge.
d. Position each round cable cover horizontally over the hinges, and align the
hinge connectors with the hinges.
e. Using your thumb, apply downward pressure on each hinge connector to snap
the hinge connector into place.
f. Swing the cable covers down and press down on the cable cover handle to
lock them into the closed position.
3. Ensure that the six Velcro straps are threaded into the CMA.
4. To prevent the rack from tipping, ensure all anti-tilt devices on the rack are
extended.
