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.
   
   
   
2. Insert the CMA mounting bracket connector into the right slide rail until the connector locks into place.
   
   
   
3. Insert the right CMA slide rail connector (1) into the right slide rail assembly (2) until the connector locks into place.
   
   
   
4. Insert the left CMA slide rail connector (1) into the rail extension on the left slide rail assembly (2) until the connector locks into place.
   
   
   
5. After you install and route the cables through the assembly, attach the hook and loop straps (1) to secure the cables. Then attach the right and left outer latches to support the assembly.
