Installing the expandable rails and extension bracket into the rack

You might need to install rails into the rack. Use the procedure in this section to perform this task. In addition to related safety information, this section also includes illustrations of the related hardware components and shows how these components relate to each other.

Attention: Installing the rails in the rack is a complex procedure. To install the rails correctly, you must perform each task in the following order. Failure to do so might cause rail failure and potential danger to yourself and the system unit.

To install the expandable rails into the rack, complete the following steps:

  1. Loosen the two screws (B) in the middle of both rails (A) to allow each rail to extend.

  2. Starting at the rear of the rack, extend the left rail. Insert the rail pins (C) into the marked locations on the rack so that it is facing upward (L shape).
  3. From the rear of the rack, extend the right rail and insert the rail pins (C) into the marked locations.
  4. Move to the front of the rack, extend the left rail and insert the rail pins (C) into the marked locations.
  5. Extend the right rail and insert the rail pins (C) into the marked locations.
  6. Using one M5 screw (D), secure the left rail to the front of the rack into the lower location (A).
    Important: Do not install a screw in the top location at this time. It will secure the shell to the assembly.

  7. Using one M5 screw (D), secure the right rail to the front of the rack into the lower location (A).
  8. Move to the rear of the rack and locate the marks that were previously made on the back-left rail. Using two M5 screws (G), secure the rail arm to the rack at the location of the two lowest marks.

  9. Align the top alignment pin of the bracket (F) with the highest mark, and use one M5 screw (G) to secure the bracket to the rack at this location.
    Note: The bracket will face inward.
  10. Locate the marks that were previously made on the back-right rail of the rack. Using two M5 screws (G), secure the rail arm to the rack at the location of the two lowest marks.
  11. Align the top alignment pin of the bracket (F) with the highest mark, and use one M5 screw (G) to secure the bracket to the rack at this location.
  12. Tighten the two screws (B) in the middle of the left rail and the two screws (B) in the middle of the right rail. See Figure 1.
