Installing the cable management assembly

Installing a cable management assembly (CMA) can help keep the system neat and organized.
Steps
1. Align and insert the CMA tabs in the tongues on the rails and align the plunger in the hole of the mounting rail on both sides.
2. Working one side at a time, pull out the plunger and slide the CMA tabs as required until the plunger pin snaps into the
mounting hole of the rail.

3. Open the velcro straps to route cables through the CMA. Secure the cables in place using the velcro straps.
4. To adjust the CMA position depth (in or out), pull inward on the orange latches (1) and pull out or push in on the arm
simultaneously as needed (2).
NOTE: The I/O modules, the NVRAM module, the power supply units and the 2.5" disks can be accessed for removal
and replacement with the CMA in place. Adjust the depth of the CMA arms to access these modules.
