Replacing the SAN Volume Controller 2145-CF8 cable-management arm

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

1. At the rear of the rack, connect one end of the support arm, as shown by  1  in Figure 1, 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.

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

3. To attach the other side of the support arm to the backside of the slide rail, push the blue latch on the cable-support-arm stop bracket, as shown by  1  in Figure 3, to slide the bracket  2  into the slide rail.

4. 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 4.

   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.

5. Place the cable-management arm on the support arm.
   1. Pull out the cable-management arm pin, as shown by  1  in Figure 5, 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.

6. Attach the power cords and data cables to the rear of the node.
   1. Route the cables and power cords on the cable-management arm, as shown by  1  in Figure 6.

      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 from the fully extended rail position 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.
