Before installing the DS4700 Express in a rack cabinet, you must install the rails and rack-mounting hardware that come with your storage subsystem. The DS4700 Express 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, is 60.96 cm (24 in.) minimum and 81.28 cm (32 in.) maximum. This rack conforms to the EIA standard. Where you place the support rails in the rack depends on where you intend to position the storage subsystem.

Complete the following steps to install the support rails:

Note: Refer to Figure 20 on page 40 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 to prevent the rack from tipping forward while the DS4700 Express is being installed.

Refer to the installation and service guide, or equivalent, for the rack as required.

3.Locate the two support rails, eight of the twelve M5 screws, and eight washers that are supplied with the DS4700 Express.

Note: The M5 screws and washers may already be attached to the support rails. If so, remove them from the support rails.
