Installing the support rails
Before installing the DS4100 in a rack cabinet, you must install the rails and
rack-mounting hardware that come with your storage server. The DS4100 requires
an Electronic Industries Association (EIA) 310-D Type A 19-inch rack cabinet. The
distance between EIA rails, from the front to the rear of the rack cabinet, is 60.96
cm (24 in.) minimum and 81.28 cm (32 in.) maximum. This rack cabinet conforms to
the EIA standard. Where you place the support rails in the rack cabinet depends on
where you intend to position the storage server.
Complete the following steps to install the support rails:
Note: Refer to Figure 12 on page 24 while performing these steps.
1. Ensure that the rack cabinet has already been installed.
2. Ensure that a stabilizer has been correctly attached to the bottom front of the
rack cabinet to prevent the rack cabinet from tipping forward while the DS4100
is being installed.
Refer to the installation and service guide, or equivalent, for the rack cabinet
as required.
3. Locate the two support rails and six of the eight M6 screws that are supplied
with the DS4100.
