Installing the support rails
Notes:
1. For proper weight distribution, install the support rails from the storage subsystem ship group in the
lower portion of the rack cabinet.
2. If you are installing a storage subsystem, make sure that you allow for room above and below the
storage subsystem for storage enclosures.
3. The support rails are marked “R” and “L” for right and left.
To install the left and right support rails in the rack cabinet, complete the following steps.
1. Starting with the left support rail, loosen the two rail adjustment screws. The adjustment screws are
used to lock the support rails at a certain length.
2. Hold the front of the left support rail against the inside of the front rack cabinet support flange, and
extend the rear of the support rail until it makes contact with the rear rack cabinet support flange.
The alignment spacers at the rear of the support rail slide into the holes at the rear of the rack cabinet,
as shown in Figure 2.
Note: If the rack has square holes, replace the small spacers on the front and rear of the rails with the
larger spacers that came with the rail kit.
3. From the front of the rack cabinet, with the support-rail flanges positioned inside the rack cabinet
support rail assemblies, tighten one M5 screw in the second hole from the top of the rail bracket with
