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.
Note: The 1 EIA unit in racks are measured in vertical increments of 44.45 mm (1.75 in.) each. Each
44.45 mm (1.75 in.) increment is called an “EIA.” In some countries, the same increment can be
referred to as a “U.”
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:
- 4 - Philips 6.35 mm (0.25 in.) screws
- 2 - Inner rails
- 2 - HMC support rails
- 2 - Nut clips for square EIA mounting holes
- 2 - Nut clips for round EIA mounting holes
- 8 - M5 hex flange screws
