Note: Proceed to Install the 12-Drive and 24-Drive Chassis Rails on the next page if either condition
applies:
Hanger fasteners are pre-installed in rail sets; or
You are installing into a rack with pre-tapped holes.
If installing into square or round-hole racks, install the hanger fasteners in the front and rear rail components
with the heads facing inward. Front rail sleeves require two pins each, and rear rail inserts each require one
pin. Loosely attached fasteners temporarily hold the rails in place before being secured, enabling vertical
and horizontal positioning for accurate alignment.
Note: Hanger fasteners (pins) may be pre-installed.

Install the 12-Drive and 24-Drive Chassis Rails
To install rack rails for the 12-drive and 24-drive chassis, you will need to complete the following steps.
Installation Steps
a. Review all prerequisites. See Install QXS RAID and Expansion Chassis.
b. Attach the side brackets to the rear mounting holes on each side of the chassis.
c. If you are installing the chassis into square or round-hole racks, you need to install hanger fasteners
in the front and rear rail components.
Proceed to Step 3: Install the Rails on page 11 if either or the following are true:
lHanger fasteners are pre-installed in rail sets.
lYou are installing the chassis into a rack with pre-tapped holes.
d. Install the rails for the 12 and 24-drive chassis. Keep in mind that the rail kit supports both the
controller and expansion chassis.
Step 1: Attach Side Brackets
1. Use 2 #8-32 x 3/16 flathead Phillips screws to attach a side bracket to the rear mounting holes on one
side of the chassis.

Step 2: Install Hanger Fasteners
1. Install the hanger fasteners in the front rail components with the heads facing inward.
Front rail sleeves require two pins each.
2. Install the hanger fasteners in the rear rail components with the heads facing inward.
Rear rail inserts require one pin each.
Keep in mind that you can loosely attach the fasteners to the hold the rails in place, and then position the
rails vertically and horizontally for accurate alignment. As soon as you have an accurate alignment,
tighten the fasteners.
