Installing the cable-management arm and connecting and routing power cables

The cable-management arm is used to efficiently route cables so that you have proper access to the rear of the system. After you have installed the cable-management arm, connect and route power cables.

1. Ensure that you have the following parts.

   A	Support arm
   B	Cable-management stop bracket
   C	Mounting bracket
   D	Cable-management arm
   E	Extension bracket

2. Connect one end of the support arm (A) to the right slide rail (1) so that you can swing the other end of the support arm toward the left side of the rack (2).
   Note: The support arm (A) is labeled UP and DOWN. Ensure that the side labeled UP is facing upward and to the right.

3. Locate the hole at the bottom inside corner of the L-shaped cable-management stop bracket (B). Position the unattached end of the support arm so that the locking tab on the underside of its tip aligns with the bracket hole. Insert the tab into the hole (1) and turn the bracket (2) to secure it to the support arm. For details, see Figure 3.

7. Place the cable-management arm (D) on the support arm (A). Slide the first cable-management arm tab into the slot on the mounting bracket (C). Push the tab until the spring-loaded latch snaps into place. Slide the other cable-management arm tab into the extension bracket (E) on the outside of the right slide rail (2). Push the tab until the spring-loaded latch snaps into place. For details, see Figure 7 and Figure 8.

8. To connect the power cables, complete the following steps:
   1. Plug the power cords into the power supplies.
   2. Route the power cords and other cables on the cable-management arm.
   3. Attach all cables to the rear of the server.
