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.

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

Install the cable-management arm to pivot from the left side of the SAN Volume Controller 2145-CF8 rack, when viewed from the rear of the rack.

To attach the arm, perform the following steps:

1. Pull the node slightly out of the rack to provide space for working on the cable-management arm at the rear of the rack.
2. At the rear of the rack, connect one end of the support arm, as shown by  1  in Figure 2, to the same slide rail to which you plan to attach the cable-management arm so that you can swing the other end of the support arm  2  toward the rack.

3. Install the L-shaped cable-management stop bracket, as shown by  1  in Figure 3 on the unattached end of the support arm. Turn the bracket  2  to secure it to the support arm.

4. To attach the other side of the support arm to the backside of the slide rail, pull the pin out, as shown by  1  in Figure 4, and then slide the bracket  2  into the slide rail.

5. To install the cable-management arm assembly, you must place the cable-management arm mounting bracket into the same slide rail onto which you installed the cable-management support arm.

   The cable-management support arm is not shown in Figure 5.

   Push the blue latch on the cable-support-arm stop bracket  1  to slide the mounting bracket  2  into the left slide rail. Push the bracket into the slide rail until the bracket snaps into place.

6. Place the cable-management arm on the support arm.
   1. Pull out the cable-management arm pin, as shown by  1  in Figure 6, then slide the cable-management arm tab  2  into the slot on the inside of the slide rail.
   2. Push the tab until it snaps into place.
   3. Pull out the other cable-management arm pin  3 , then slide the cable-management arm tab into the slot  4  on the outside of the slide rail.
   4. Push the tab until it snaps into place.

7. Slide the SAN Volume Controller 2145-CF8 into the rack until it latches into place.
8. 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 7.

      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.
