How to Install a ZS4-4 or ZS3-4 Cable Management Arm

How to Install 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.
■
Insert the CMA mounting bracket connector (1) into the right slide rail (2) until
1.
the connector locks into place with an audible click.
2. Insert the right CMA slide-rail connector (1) into the right slide-rail assembly (2)
until the connector locks into place with an audible click.
