Installing the cable-management arm for the SAN Volume Controller 2145-CF8

The SAN Volume Controller 2145-CF8 uses a cable-management arm to route and secure power and communication cables.

About this task

The parts involved in installing the cable-management arm are shown in Figure 1.

Reference	Description	Quantity
1	Slide rail (left)	1
2	Slide rail (right)	1
3	M6 screws	4
4	Large cable tie	1
5	Cable ties	5
6	Cable-management support arm	1
7	Cable-management arm assembly	1

To attach the arm, perform the following steps:

1. At the rear of the rack, install the cable-management-support arm.
   Insert both ends of the cable management support arm into the slide rail, as shown by Figure 2.

2. Install the cable management arm, as shown in Figure 3.

   Note: Make sure that the junctions on the arm, as shown by  1  in Figure 3, are facing the SAN Volume Controller 2145-CF8.

   Place the cable management arm on the support arm. Pull out both cable-management-arm pins and then slide the cable-management-arm tabs into the slots on both the inside and the outside of the slide rail. Push the tabs until they snap into place.

3. Adjust the location of the cable management arm, as shown in Figure 4.

   Make sure that the support rail is located between the 2 nailhead features.

4. Attach the power-and-serial-cable bundle, the Fibre Channel cables, and the one or two Ethernet cables to the rear of the node.
   1. Route the data cables and power cords on the cable-management arm, as shown by  1  in Figure 5.

      If you attach the arm properly and route the cables properly, the arm swings into the rack as you pull the node forward in the rack, opening to allow the cables to follow the node toward the front of the rack. You can perform some service procedures without disconnecting the Fibre Channel cables and the Ethernet cables. You can also perform some service procedures without turning off the node or disconnecting the power cables.

   2. Secure the cables with cable ties or hook-and-loop fasteners.
   Note: Leave some slack in all of the cables to avoid tension in the cables as the cable-management arm moves.
