3. The two rail sections are screwed together to keep them immobile during shipping.
Release these screws just enough to allow the rails to slide apart. Note the arrow on the
rail, which indicates the end that attaches to the front of the rack.
4. Slide the rails apart far enough to match the depth of the rack. Position the rails with the
template and secure the front of each to the front of the rack with two flathead screws,
then secure the back of each rail to the rear of the rack with two flathead screws (see
Figure 2-2). Note that the rails are left/right specific and very heavy.

5. (Optional step) Add the front left and right handles to the chassis using five screws to
secure each handle. Install a thumbscrew through the bottom hole of each handle (see
Figure 2-3).
Note: These handles are optional and need only be installed when mounting the system into
a short rack. When mounting into a deep rack, they are unnecessary and regular screws
should be used instead of thumbscrews.
Be aware that these handles are not to be used for lifting the system, they are only to be
used to slide the system within the rack.
6. With one person on either side (see the descriptive label on the side of the chassis), lift
the system and slide it into the installed rails.
