will be installed below an existing storage system or storage enclosure, allow 178
mm (7 in.) of vertical clearance for the DCS3860.
Note:
For proper weight distribution, install the support rails as low in the rack
cabinet as possible. The rack cabinet must have a minimum depth of 100 cm (40
in.). If you are using a non-IBM rack or cabinet, review the information in
Chapter 9, “Specifications for non-IBM rack installation,” on page 149.
Complete the following steps to install the left and right support rails in the rack
cabinet:
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.
6.
From the front of the rack cabinet, with the support-rail flanges positioned
inside the rack cabinet support rail assemblies, insert two M5 screws with
washers through the front of the cabinet and screw them into the support rail
