Installing a ZS4-4 or ZS3-4 Cable Management Arm

Use the following procedure to install the cable management arm (CMA) for a ZS4-4 or ZS3-4
controller.
The CMA is an optional assembly that you can use to route the controller cables in the rack.
This procedure is completed from the back of the rack.
To prepare for installing the optional cable management arm (CMA), follow these guidelines:
Before You Begin
Route cluster cables, long-term host cables (including InfiniBand, Fibre Channel, and
■
Ethernet Cables) and up to 12 disk shelf 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 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. Insert the CMA mounting bracket connector (1) into the right slide rail (2) until
the connector locks into place with an audible click.
Verify that the controller is securely mounted in the rack and that the slide-rail locks
