IBM DS4800 - Securing the DS4800 to the Rack Cabinet

Attention: If you have removed the components from the DS4800, you should be
able to lift the unit from the shipping box and into the cabinet with the help of one
other person. (If you have not removed the components before the installation, you
should have at least two other people available to help you lift the unit from the
shipping box and into the rack cabinet.) For safety reasons, IBM does not
recommend moving the DS4800 Storage Subsystem from the shipping box and
installing the DS4800 on the support rails without first removing all CRU
components.
1. Remove the empty DS4800 Storage Subsystem from the shipping box and set
the storage subsystem in the cabinet. Figure 20 shows the correct orientation of
the empty storage subsystem to the cabinet and support rail.
a. If you have installed a screw in the upper mounting hole at the front of each
support rail, remove the upper screws. These two screws are used later to
secure the front of the storage subsystem to the rack.
b. Move the empty storage subsystem from the shipping box and to the front of
the cabinet.
c. With help from another person, place the back of the storage subsystem on
the support rails, and then slide the storage subsystem into the cabinet.
Attention: When you slide the storage subsystem into the cabinet, verify
that the back of the DS4800 Storage Subsystem is secured by the
hold-down clips located at the back of each rail. With the M5 rail screws
loosely threaded, you can make minor adjustments to the rails to ensure that
the subsystem latches in the hold-down clips. The hold-down clips are
shown in Figure 14 on page 35.
2. Secure the storage subsystem to the cabinet. Figure 20 shows how to secure
the DS4800 to the vertical members of the cabinet.
a. Align the front mounting holes on the storage subsystem flanges with the
mounting holes on the cabinet.
