Installing a 4U storage processor enclosure (SPE) in a cabinet

Installing the adjustable rails
1. Locate and unpack the rail kit that accompanied your enclosure.
The front edge of each rail is stamped L or R for left and right
sides, when they face the cabinet front.
Note: The predrilled holes in the cabinet channels are based on the
NEMA-standard U measurement. The holes are predrilled at distances of
1/2 inch, 5/8 inch, 5/8 inch (totaling one U), then 1/2 inch, 5/8 inch, 5/8
inch (another U), and so on. On EMC 40U and 40U-C cabinets, horizontal
lines or small holes in the channel mark the 1U increments.
2. From the front of the cabinet, insert the right rail alignment pins
(attached to the rear of the adjustable rail) in the middle holes of
the second and third U on the rear NEMA channel. Figure 34
shows the correct channel holes for the alignment pins.
