Attaching the fixed rails to the system chassis and to the rack

You must install the rails onto the chassis and into the rack. Use this procedure to perform this task.

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.If you don’t have the correct rails and fittings for your rack, contact your reseller.
Note: The system requires 1 EIA rack unit (1U) of space.

Ensure that you have the necessary parts to install the rails. The following parts are included with the rail kit:

  • Slide rail screws, used to attach the two parts of each slide rail
  • Slide rail rack screws, used to secure the rails to the rack
  • Rails
  • 10 - 32 x 0.635 cm (0.25 in.) screws, used to attach the rails to system chassis

Procedure

  1. Remove the rail pieces from the packaging and put them on a work surface.
  2. Replace the rail rack square pins (A) and (D) with the rail rack round pins.
  3. Connect the two parts of each rack slide rail. To connect the two parts of the rack slide rail, perform the following tasks:
    1. Identify the two pieces of the left rack slide rail. Align the short and long pieces (C). Ensure that the rack rail pins are pointing in the same direction (A) and (D).

    2. The shorter piece of the rack slide rail has a metal pin. Insert the pin into the hole in the longer piece of the rack slide rail (B). Slide the shorter piece of the rack rail into the longer piece of the rack rail.
    3. Align the holes in the two pieces of the rack slide rails. Using a Philips-head screwdriver, attach the two parts by loosely screwing two threaded rail screws through the holes in the rack slide rail.
      Note: Do not tighten the rack slide rail screws.
    4. Repeat these steps for the right slide rail.
  4. Install the rack slide rails into the rack.
    1. Move to the front of the rack.
    2. Select the left rack slide rail, and locate the EIA unit that you previously marked. Each slide rail is also marked Back, to designate the rear of the rack. Ensure that you are holding the front end of the rack slide rail.
    3. Extend the rail from the front of the rack to the back of the rack and align the rack slide rail pins with the holes in the rack flange that you previously marked.
    4. Push the rack rail pins into the rear rack flange until the rear rack rail latch clicks into place.
    5. Pull the front of the rack rail toward the front of the rack rail flange. Align the slide rail pins with the holes in the rail flange and pull them until the rail latch clicks into place.
    6. Using a screwdriver, tighten the rail screws that you installed in step 2.
      Note: You might need 2U of space to access and tighten the rail screws.
    7. Repeat steps 4a - 4f for the right slide rail.
