Installing a ZS3-2 Cable Management Arm
Use the following procedure to install the optional cable management arm (CMA) on a ZS3-2
controller.
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 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.
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.
