IBM S824L Installing page 21

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.
To install the mounting hardware into the rack, complete the following steps:
1. Rotate down the front and back clamps (C) on the left and right rails as shown in
Figure 4. Installing the rails
2. 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 as shown in
3. Starting at the front of the rack, complete the following steps:
a. 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 as shown in
b. Rotate up the front clamp (C) to secure the rail in place as shown in
