Storwize V7000 Gen2 and Gen2+: Quick Installation Guide
1. Locate the expansion enclosure rails (Figure 12). The rail assembly consists of
two rails that must be installed in the rack cabinet.
2. Locate the hardware that is used to install the rails, including two rail springs,
two sets of eight bracket pins, and two M5 screws. Set the hardware aside for
use later in the installation process.
3. Install a spring on each rail.
a. Extend the rail to its full length.
b. Push one looped end of a spring over one stud on the inside of the rail.
(See Figure 13 on page 17.)
Note: Some models of rail have the studs on the outside of the rail.
c. Stretch the spring slightly and push the other looped end of the spring
onto the other stud on the inside of the rail.
