SnapServer®2000 Series/REO®4600
Rack Installation
IMPORTANT: The server can only be mounted in a four-post,
32-inch depth, EIA-compliant rack. A two-post telco-style rack
or a rack less than 32 inches in depth will not support the
server.
In addition, round-hole and threaded racks, which will require
rail adapters, must have an available depth of at least 29
inches. If your rack has been adjusted to under 29 inches
depth, you will need to reset the rack depth.
The server ships with two slide rail assemblies
consisting of inner rails to attach to the chassis, outer
rails to attach to the rack, a packet of screws for
mounting the rails to the chassis and to the rack, and a
pair of adapters for installing the rails in round-hole
racks (see Figure 1).
Figure 1. Rail Kit Contents
The rails are not universal. They are stamped LH (left)
and RH (right) and must be mounted correctly. You will
need a Phillips screwdriver to mount the rails and a
second person to help position the server into the rack.
Attach the Inner Rails to the Chassis
1. Remove the inner rails from the outer rails by
expanding the outer rail, then sliding the inner rail
out as far as it will go. Press the lever on the inner
rail to slide it out completely (see Figure 2).
Figure 2. Remove Inner Rails
2. Facing the front of the chassis, take the right-
branded inner rail and position it on the right side of
the chassis toward the rear. The tongues on the
chassis should fit through the rectangular holes on
the rail, and the rail release mechanism should be
facing out.
Figure 3. Attach Inner Rails
3. Slide the rail toward the front of the unit, and
continue to slide until you can feel that it’s attached
securely (see Figure 3).
4. Fasten with the rail attachment Phillips screw.
5. Repeat Steps 1 - 4 for the left-branded inner rail.
Attach Adapters to Outer
Rails (Round-Hole or
Threaded Rack Only)
To install the server in a round-hole or
threaded rack, attach the adapters
included in the rail kit to the outer rails
before installing the rails in the rack.
NOTE: Some early model rail kits contain a different
adapter than the one described in this procedure. If your
adapter does not look like the illustration above, go to
“Attach Early-Model Adapters to Outer Rails (Round Hole
Rack Only)”.
1. Position one of the adapters at the front of the left
outer rail so that the two square holes and two round
holes fit against the front of the rail and the open side
is facing outward (see Figure 4).
NOTE: The outer rails are not stamped left and right. To
determine the correct positioning, make sure that, as you
install the rail, the illustration (see Figure 1) is right side
up, toward the front of the rack,and facing away from the
server.

2. Depress the square rail buttons and slide the adapter
onto the metal hooks of the left outer rail, then slide
the adapter up until it snaps into place with the rail
buttons extended through the adapter holes (see
Figure 4).
Figure 4. Attach Adapter to Outer Rail
3. Attach an adapter to the rear of the left outer rail,
using the same process you followed in Step 2.
4. Repeat Steps 1 - 3 for the right outer rail.
Attach Early-Model
Adapters to Outer Rails
(Round Hole Rack Only)
If the adapters in your rail kit resemble
the illustration to the right, use the
following procedure to install the
adapters on the outer rails before
installing the rails in the rack.
NOTE: These adapters cannot be used with threaded-hole
racks.
1. The brackets are stamped A and B. Position an A
bracket at the front of the left outer rail and a B
bracket at the rear of the left outer rail.
NOTE: The outer rails are not stamped left and right. To
determine the correct positioning, make sure that, as you
install the rail, the illustration (see Figure 1) is right side up,
toward the front of the rack,and facing away from the
server.
2. Depress the square rail buttons and slide the A
bracket onto the metal hooks of the left outer rail,
then slide the bracket up until it snaps into place and
the rail buttons extend through the adapter holes (see
Figure 5).
Figure 5. Attach Adapter to Outer Rail (early models)
3. Attach a B bracket to the rear of the left outer rail,
using the same process you followed in Step 2.
4. Repeat Steps 1 - 3 for the right outer rail.
Attach the Outer Rails to the Rack
NOTE: If you are using adapters, the rack must have a minimum
depth of 29 inches for the rails to install.
1. If the outer rails are extended, press the release lever
on the inside of the rail and collapse the rails.
Figure 6. Collapse Outer Rail
2. Take the left outer rail and position it on the left side
of the rack (as you are facing the front of the rack).
NOTE: The outer rails are not stamped left and right. To
determine the correct positioning, make sure that, as you
install the rail, the illustration (see Figure 1) is right side up,
toward the front of the rack,and facing away from the
server.
a. On square-hole racks, depress the square buttons
on the front ends of the outer rail, slide the metal
hooks into the rack holes, then slide the rail down
until the hooks are securely caught and the
buttons extend through the rack holes (see
Figure 7).
NOTE: Secure the rail to the rack with the countersunk
screws and cup washers from the rail kit. Attach two
washers and screws to each of the rear rails and a single
washer and screw in the lower front position. The upper
front screw hole can then be used to secure the server.

b. On round-hole or threaded racks, position the rail
adapter to to fit around the rack post and align
the holes in the adapter with the holes in the rack
(see Figure 8). Secure the adapter to the rack
using the cup washers and countersunk screws
from the rail kit. On round-hole racks, use
captive-nut rack clips (not included in rack kit) to
secure the screws.
NOTE: If you plan to secure the Snap Server to the rack
(recommended), secure the rail by placing a single cup
washer and countersunk screw in the front lower position.
The upper front screw hole can then be used to secure
the server.

or Threaded Hole Rack
c. If you have early model adapters, position the
outer rail so the adapter is flush against the inside
of the rack post, aligned with the post holes.
Secure the adapter to the rack using the
countersunk rail kit screws (without cup
washers).
NOTE: If you plan to secure the Snap Server to the rack
(recommended), secure the rail by placing a single screw
in the front lower position. The upper front screw hole can
then be used to secure the server.

early model adapters)
4. Repeat Step 2 on the rear of the left rail.
5. Repeat Steps 2 - 4 for the right rail.
Insert the Server into the Rack
CAUTION: The server is awkward and heavy. Do not try to install
it without another person’s assistance.
1. Extend the outer rails until they lock into place.
2. Align the inner rails on the chassis to the extended
outer rails on the rack and slide the chassis into the
rack (see Figure 10).
Figure 10. Insert the Server into the Rack
3. Use two of the 12/24-in kit screws to secure the server
flanges to the rack.
Remove the Server from the Rack
CAUTION: The server is awkward and heavy. Do not try to install
it without another person’s assistance.
Once the Snap Server is installed in the rack, it locks into
place. To remove the server, perform the following steps:
1. Remove the screws attaching the server flanges to the
rack.
2. Slide the server forward.
3. Once the outer rails are extended, press down on the
release mechanisms of the chassis rails (see Figure 2)
at the same time and slide the server the rest of the
way out of the rack.
