Installing The Support Rails And Rear Brackets - IBM DCS3700 Quick Start Manual

Installing the support rails and rear brackets

Note: Use the front and rear rack-mounting templates on pages 19 and 20 to align the support rails and
rear brackets with the correct rack holes. If the support rails will be installed above an existing
storage subsystem or storage enclosure, position the DCS3700 or DCS3700 storage subsystem with
Performance Module Controllers support rails directly above it. If the support rails will be installed
below an existing storage subsystem or storage enclosure, allow 178 mm (7 inches) of vertical
clearance for the DCS3700 or DCS3700 storage subsystem with Performance Module Controllers.
To install the left and right support rails in the rack cabinet, complete the following steps. Use the front
and rear rack-mounting templates on pages 19 and 20 to align the support rails and rear brackets with
the correct rack holes. If the support rails will be installed above an existing storage subsystem or storage
enclosure, position the DCS3700 or DCS3700 storage systems with Performance Module Controllers
support rails directly above it. If the support rails will be installed below an existing storage subsystem
or storage enclosure, allow 178 mm (7 in.) of vertical clearance for the DCS3700 storage subsystem or
DCS3700 storage subsystem with Performance Module Controllers.
1. Ensure that the rack has already been installed.
2. Ensure that a stabilizer has been attached correctly to the bottom front of the rack to prevent the
rack from tipping forward while the storage enclosure is being installed.
Refer to the installation and service guide, or equivalent, for the rack as required.
3. Locate the two support rails, eight M5 screws, and eight washers that are supplied with the storage
enclosure.
Note: The screws and washers might already be attached to the support rails. If so, remove them
from the support rails.
4. Starting with the left support rail, loosen the two rail adjustment screws with a medium flat-blade
screwdriver. The adjustment screws are used to lock the support rails at a certain length.
Note: The support rails are not marked as left or right. However, each rail can be mounted correctly
on only one side of the rack cabinet. The rails should be mounted with the alignment pin at
the rear of the rack.
5. 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 pins at the rear of the support rail slide into the mounting holes at the rear of the
rack cabinet. The wider end of the support rail must be positioned at the front of the rack cabinet.
