SC933 Chassis Manual
Rack Mounting Instructions
This section provides information on installing the SC933 chassis into a rack unit
with the rails provided. There are a variety of rack units on the market, which may
mean the assembly procedure will differ slightly. You should also refer to the installation instructions that came with the rack unit you are using.
NOTE: This rail will fit a rack between 28" and 33.67" deep.
Identifying the Sections of the Rack Rails
The chassis package includes two rack rail assemblies : an inner fixed chassis rail
that secures directly to the server chassis and an outer fixed rack rail that secures
directly to the rack itself.

(right side rail shown)
Inner Rail Extension
The SC933 chassis includes a set of inner rails in two sections: inner rails and inner
rail extensions. The inner rails are preattached and do not interfere with normal use
of the chassis if you decide not to use a server rack. Attach the inner rail extension
to stabilize the chassis within the rack.

(right side rail shown)
Installing the Inner Rails
1. Place the inner rack extensions on the side of the chassis aligning the hooks
of the chassis with the rail extension holes. Make sure the extension faces
"outward" just like the preattached inner rail.
2. Slide the extension toward the front of the chassis.
3. Secure the chassis with 1 screws as illustrated.
4. Repeat steps 1-3 for the other inner rail extension.

Installing the Outer Rails to the Rack
1. Attach the short bracket to the outside of the long bracket. You must align the
pins with the slides. Also, both bracket ends must face the same direction.
2. Adjust both the short and long brackets to the proper distance so that the rail
fits snugly into the rack.
3. Secure the long bracket to the front side of the outer rail with two M5 screws
and the short bracket to the rear side of the outer rail with three M5 screws.
4. Repeat steps 1-3 for the remaining outer rail.

Installing the Chassis into a Rack
1. Confirm that chassis inner rails and outer rails are installed on the rack.
2. Line chassis rails with the front of the rack rails..
3. Slide the chassis rails into the rack rails, keeping the pressure even on both
sides (you may have to depress the locking tabs when inserting). When the
server has been pushed completely into the rack, the locking tabs will click
into the locked position.
4. (Optional) Insert and tightening the thumbscrews that hold the front of the
server to the rack.
