Installing a ZS5-4 Cable Management Arm
until the slide-rail locks (on the front of the mounting brackets) engage the slide-
rail assemblies.
Caution - Verify that the controller is securely mounted in the rack and that the slide-rail locks
are engaged with the mounting brackets before continuing, or equipment damage or possibly
injury could occur.
Installing a ZS5-4 Cable Management Arm
Use the following procedure to install the cable management arm (CMA) for a ZS5-4 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.
Before You Begin
Unpack the CMA and identify its components.
To prepare for installing the optional cable management arm (CMA), follow these guidelines:
■
Route cluster cables, long-term host cables (including InfiniBand, Fibre Channel, and
Ethernet cables) and up to 16 disk shelf SAS cables through the CMA. Older CMAs,
generally before 2018, only have a maximum capacity of 12 SAS cables.
■
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.
