Installing a Sun ZFS Storage 7x20 Cable Management Arm
Use the following procedure to install the optional cable management arm (CMA) for a
Sun ZFS Storage 7x20 controller.
This procedure is completed from the back of the equipment rack.
Before You Begin
Unpack the CMA and identify its components.
To prepare for installing the optional 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. Attach the CMA rail extension to the left slide rail until the extension locks into
place.
