This installation guide provides instructions for trained service technicians i nstalling
one or more Dell PowerEdge 2300 systems in a Dell rack. One rack kit is required for
each PowerEdge system to be installed in the rack. The rack kit includes the following
items (see Figure 1):
One pair of slide assemblies with mounting bracket s
One computer top cover with attached rail and rack adapter
One rail
One rack adapter
One cable-management arm
Four curved nut plates
One cage-nut installation tool
Fourteen 10-32 pan-head Phillips-head screws
Seven 8-32 pan-head Phillips-head screws
Ten #10 flat metal washers
Six 10-32 cage nuts
NOTES: The nonmetric screws called out in illustrations and procedural steps are
identified first by size and then by the number of threads per inch. For example, a #10
Phillips-head screw with 32 threads per inch is identified as a 10-32 screw .
If you have purchased a Dell rack along with your PowerEdge 2300 system, the slide
assemblies are preinstalled in the rack.

If you intend to install more than one PowerEdge 2300 system in the rack, you
must install the slide assemblies so that there is 10.5 inches (6U) of vertical
space between the top of one slide assembly and the top of the next (see
Figure 4). In the Dell rack, the rails of the rack are marked by small indentations in
1U (1.75-inch) increments. To install the computer in the racks lowest position,
locate the cage nuts 6U (10.5 inches) f rom the bottom of each vertical rail . After
determining where to install the slide assemblies, mark the locations of the cage
nuts on the racks vertical rails with a felt-tipped marker or masking tape.

Install the curved nut plates on the vertical rails where you want the ends of the
slide assemblies to be located (see Figure 5). Each curved nut plate is held in
place by one Phillips-head screw and one cage nut.
The following substeps explain how to install the cage nuts and the nut plates:
a. Insert the lower lip of the 10-32 cage nut over the bottom of the opening in
the back of a rail as shown in step 1 in Figure 5. Then insert the small end of
the cage-nut installation tool through the opening in the rail (from the front),
and hook the tool over the top lip of the cage nut.
b. Push in on the cage nut while rotating the tool up and pulling the tool back
toward you until the top lip of the cage nut snaps into position (see step 1 in
Figure 5).
c. Repeat this process to install the remaining cage nuts.
d. To install one of the curved nut plates, insert it through the hole below the
cage nut (from the back of the rail) as shown in step 2 in Figure 5. Then
secure the nut plate in place with a 10-32 x 0.5-inch Phillips-head screw ( see
step 3 in Figure 5).
e. Repeat substeps a through d to install the remaining nut plates.

NOTES: When installing the slide assemblies, be sure that the green plastic
stops at the ends of the channels are at the back of the rack and that the green
push button (on the interior slide) is near the front of the rack (see Figure 11).
If the slide assembly is completely extended and locked in position, press the
spring located on the inside of the interior slide (near the end with the green plas-

b. Position the mounting bracket at the back of the slide assembly so that its
two slots are aligned with the two lowest holes in the nut plate (see Fig -
ure 6). Secure the mounting bracket with two 10-32 x 0.5-inc h Phillips-head
screws and two #10 flat metal washers. Do not completely tighten the two
mounting screws until you install the computer and verify that the width
between the slide assemblies is correct.
c. Position the mounting bracket at the front of the slide assembly so that its
two slots are aligned with the two lowest holes in the nut plate . Secure the
mounting bracket using two 10-32 x 0.5-inch Phillips-head screws and two
#10 flat metal washers .
d. If necessary, adjust the slide assemblys length until the mounting-bracket
flange fits snugly against the back of the rails on both ends . (Dell racks
require no adjustment to the slide assemblies; the slide assemblies a re pre-
configured to the correct length).
e. Tighten the slide alignment screw you loosened in step 3.

The slotted holes in the slide-mounting brackets allow for adjustment if the width
between the slide assemblies is not correct. Adjust the width so that the com-
puter slides easily into place.
NOTE: As you push the computer into the interior slides, the slide assemblies

After you tighten all of the mounting-bracket screws, slide the computer in and
out a few times to ensure that none of the adjustments changed as you tight-
ened the screws.

Use two 10-32 x 0.5-inch Phillips-head screws and two #10 flat metal washers to
secure the cable-management arm to the back vertical rail as shown in Figure 10.
(This is the rail on the right as you face the back of the rack.) Make sure that the
cable-management arm is straight in relation to the computerthat is, parallel to
the ground.

Connect the cables to the computer. For details, see the computer systems
Installation and Troubleshooting Guide and Users Guide.

After connecting the cables to the computer, route the cables along the cable-
management arm, and secure the cables to the cable-management arm with the

Make sure that the cables are not pinched in the cable-management arm joints.
NOTES: You will feel resistance as the rails thread themselves into the ball-bear-
ing cages in the slide assembliesthis resistance is normal. Continue to push
the computer inward until it slides completely into the rack and is fully seated.
(You may have to pull the computer partially out and push it back into the rack to
fully thread the ball-bearing cages.) When fully engaged, the back of the four cap-
tive thumbscrews should mate with the cage nuts on the racks front vertical
rails.
As you pull the computer out to its furthest extension, the slide assemblies will
lock in the extended position. To push the computer back into the rack, press the
green buttons near the front of both interior slides (see Figure 10) and simulta-
neously push in on the computer.
