All excess cabling that cannot be fitted through the CMA should be attached to the
side of the rack and properly dressed (Velcro straps, and so on). Allow enough
slack (service loop) for serviceability.
• Up to 16 AOC SAS cables can be routed through the CMA.
• ZS9-2 controllers that support a mix of AOC and copper SAS cables can route up
to 12 AOC and 4 copper SAS cables through the CMA.
• 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 that they properly route to the upper and lower disk
shelves.
• If uninstalling equipment and the CMA requires removal, be sure to support the
CMA as you remove the connectors.
1. Unpack the CMA and identify its components.
