Before You Begin
Before you begin, please review the following cautions, warnings, and general
guidelines.
!
WARNING
Be sure that power to the server unit is turned off and
unplugged. All voltage is removed only when the power cord
is unplugged.
!Avoid excessive vibration and shock. Dropping an electronic component can
cause serious damage.
!Do not disconnect or remove parts other than those specified in the
procedure.
!Do not touch I/O connector pins.
!All screws are Phillips-head, unless otherwise specified.
!On completion of any reassembly, perform a power-on test. If a fault occurs,
verify that the reassembly was performed correctly. If the problem persists,
see the Problem Solving chapter in your System User’s Guide.
What You Need
In addition to the carton contents, the only tools you need are a #2 Phillips,
adjustable crescent wrench, and a utility knife to assemble the server unit.
!
CAUTION
It is strongly recommended that two people are present
when lifting and installing the server unit into a system rack.
Static Precautions
An electrostatic discharge (ESD) can damage disk drives, option boards, and
other components. You can provide some ESD protection by wearing an anti-
static wrist strap attached to chassis ground when handling system components.
Electronic devices can be easily damaged by static electricity. To prevent
damage, keep them in their protective packaging when they are not installed in
your system.

Equipment Information
!Measurements for the rack are given in Us where 1U is equal to 1.75 inches.
!Every three holes on the inside of the rack are equal to 1U.
!The height of the Server Small Tower Unit is 5Us (8.75 inches).
Preparing Your Server Unit
To prepare your server small tower unit for rack mounting, you must first
remove the front bezel, the side panels, and the four foot stands on the bottom of
the unit. After the previously mentioned items are removed, then the new front
bezel for rack mounting can be installed on the front of the server unit.
Removing the Front Bezel
!
CAUTION
If you are removing the front bezel after the server unit is set
up, you must first power off the system and all external
devices. Unplug the system power cord
The plastic front bezel assembly on your server unit is a one-piece assembly and
easy to remove.
Note: The front bezel is secured with six locking tabs.
1. Power off the server unit and ensure it is disconnected from the ac wall
outlet.
2. Remove the front bezel by carefully pulling it off the front of the server unit
chassis. Use an even amount of pressure around the edges of the bezel.
(see Figure 3).

Removing the Side Panels
!
CAUTION
If you are removing a side panel after the server unit is set
up, you must first power off the system and all external
devices. Unplug the system power cord
To remove a side panel:
1. Power off the server unit and ensure it is disconnected from the ac wall
outlet.
2. The side panel is secured to the chassis with three screws. Remove the
screws (see Figure 4) securing the side panel. Save the screws for
reattaching the side panel.
3. Slide the side panel toward the rear of the chassis. This unlocks the locking
fingers behind the side panel.
4. Pull the side panel up and away from the chassis.
5. Remove both the right and left side panels.

Installing the LED Holder and Labels
The Power and HDD LEDs must be removed from the LED holder currently
installed on the front of the chassis and then reinserted into a new LED holder.
The Status LED remains in its current LED holder and is reinserted into its
original slot in the front of the chassis. The new LED holder is then installed in
a vacant slot on the front right-hand side of the server chassis. A name plate
logo and two other labels are then adhered to the new front bezel of the server
unit.
To install the LED Holder and labels, perform the following:
1. Power off the system and ensure it is disconnected from the ac wall outlet.
2. Remove the front bezel as described earlier in this guide.
3. Remove the side panels as described earlier in this guide.
4. Remove the LED holder currently installed on the front of the chassis by
using a pointed instrument, such as a small screwdriver or ball-point pen.
Push downward on the top tab of the LED holder while pulling the holder
away from the front of the chassis at the same time (see Figure 5).

Removing a Foot Stand
Each of the four foot stands located on the bottom of the server unit consists of a
three piece assembly and are easily removed (see Figure 10).
Note: Each foot stand is secured with two small screws.
1. Power off the system and remove the left side panel of the server unit as
described earlier in this chapter.
2. Position the server unit on its right side.
3. Remove the two screws securing the foot stand to the bottom of the server
unit. The two screws are located inside on the bottom of the server unit.
Note: If an option card is installed in the bottom
expansion slot of the server unit, it may be necessary to
remove the option card, before the hex screw can be
removed that is located under the card.
4. Remove the foot stand (stationary base, movable stand, and long stem nut)
from the server unit.
5. Repeat steps 3 and 4 until all four foot stands are removed.

5. Remove the three screws that secure three small brackets located at the top
of the new front bezel. See Figure 13. Save the screws and brackets for use
in Step 8.
6. Carefully tilt and insert the bottom tab hooks of the front bezel into the
corresponding bottom tab slots in the front of the server unit (see Figure 13).
If necessary, loosen the screws on the bottom screw brackets of the front
bezel so that the tab hooks can be easily aligned to go into the bottom tab
slots of the server unit.
!
CAUTION
Be careful not to damage LEDs protruding out from the front
of the chassis
7. Pivot the top edge of the front bezel up towards the top edge of the server
unit until its top metal tabs protrude through the top tab slots.
8. Place a screw bracket over one of the top metal tabs with its back edge up
against the inside of the chassis and secure it with a screw. Repeat this step
for the other top metal tabs.

9. Locate the three screw holes underneath the bottom of the front bezel and
loosen the screws (see Figure 14). Firmly hold the bottom of the bezel flush
against the bottom of the server chassis and tighten the screws. This will
correctly align the front bezel to the server chassis.

left inside the server unit.
2. Make sure all option boards are firmly seated in their respective slots and
that all interior cables are properly connected inside the server unit.
3. Insert the metal locking fingers on the top and bottom of the side panel into
their slots on the chassis. Slide the side panel forward as far as it will go.
4. Replace the three side panel retaining screws
(see Figure 4).
