Attaching the mounting hardware to the rack

Find information about attaching the mounting hardware to the rack and then installing the rails into the rack. The information is intended to promote safety and reliable operation, and includes illustrations of the related hardware components and shows how these components relate to each other.

About this task

Attention: To avoid rail failure and potential danger to yourself and to the unit, ensure that you have the correct rails and fittings for your rack. If your rack has square support flange holes or screw-thread support flange holes, ensure that the rails and fittings match the support flange holes that are used on your rack. Do not install mismatched hardware by using washers or spacers. If you do not have the correct rails and fittings for your rack, contact your IBM® reseller.
Important: To complete this procedure, it is suggested that you use two people to attach the rail assembly to the rack. Position one person in front of the rack and one person at the back of the rack.

Procedure

  1. Gather the rail kit parts that you need during this procedure.
    The rail kit includes the following parts:
    Note: The installation of the EMX0 PCIe3 expansion drawer does not require usage of all parts that are included in the rail kit.
    • M3 flat head screws (used only with FC 5887)
    • L-shaped brackets (used only with FC 5887)
    • M5 slotted large round head screws and M5 slotted no head screws to accommodate various racks
    • Nut clips for racks with round holes
    • Nut clips for racks with square holes
    • M5 black hex head screws
    • Rails
  2. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged into a ground jack or connected to an unpainted metal surface. If not, do so now.
  3. Rotate down the front and back clamps (C) on the left and right rails.
  4. On each rail, remove the tape that is holding the spring (B) to the rail. Hook the end of the spring around the circular standoff on the rail.

  5. Starting at the front of the rack, complete the following steps:
    1. Extend the right rail and insert the rail pins (D) into the two lowest mounting holes that are marked on the rack so that the rail is facing upward.
    2. Rotate up the front clamp (C) to secure the rail in place.
      Remember: If your rack has square mounting holes, use the larger rail pins that are provided with the rack installation kit.
    3. Extend the left rail and insert the rail pins (D) into the two lowest mounting holes that are marked on the rack. Rotate up the front clamp (C) to secure the rail in place.

  6. Move to the rear of the rack, and complete the following steps:
    1. Extend the right rail, and insert the rail pins (D) into the two lowest mounting holes that are marked on the rack. Rotate up the back clamp (C) to secure the rail in place.
    2. Extend the left rail and insert the rail pins (D) into the two lowest mounting holes that are marked on the rack. Rotate up the back clamp (C) to secure the rail in place.
    3. Use two M5 screws (E), one below each rail pin (D) to secure the left rail to the back of the rack.
    4. Use two M5 screws (E), one below each rail pin (D) to secure the right rail to the back of the rack.
  7. Move to the front of the rack and complete the following steps:
    1. Use one M5 screw (E) below the lower rail pin (D) to secure the left rail to the front of the rack.
    2. Use one M5 screw (E), below the lower rail pin (D) to secure the right rail to the front of the rack
