Safety Guidelines
Before you remove a server cover, observe these safety guidelines:
·
·
·
Only technically qualified personnel should integrate the server.
Turn off all peripheral devices connected to the server.
Turn off the server using the push-button on/off power switch on the front panel of the server,
and unplug the AC power cord from each power supply or wall outlet.
·
·
Label and disconnect all peripheral cables attached to the I/O panel on the back of the server.
Provide some electrostatic discharge (ESD) protection by wearing an antistatic wrist strap
attached to chassis ground of the server—any unpainted metal surface—when handling
components.
Server Precautions
WARNINGS
SERVER POWER ON/OFF: The push-button on/off power switch on the
front panel of the server does not turn off the AC power. To remove AC
power from the server, you must unplug each AC power cord from each
power supply or wall outlet.
HAZARDOUS CONDITIONS—POWER SUPPLY AND POWER SHARE
BACKPLANE: Hazardous voltage, current, and energy levels are present
inside the power supply and the power share backplane enclosures. There
are no user-serviceable parts inside them; servicing should only be done
by technically qualified personnel.
HAZARDOUS CONDITIONS—DEVICES AND CABLES: Hazardous electrical
conditions may be present on power, telephone, and communication
cables. Turn off the server and disconnect telecommunications systems,
networks, modems, and each power cord attached to the server before
opening it. Otherwise, personal injury or equipment damage can result.
AVOID INJURY: To avoid personal injury when unpacking the server, use
only a mechanical assist unit to lift it off the shipping pallet. The
minimum server configuration weighs 38 kg (85 lbs); the maximum weighs
45 kg (100 lbs).
Do not attempt to lift or move the server by the handles on the power
supplies.
Use only a hand-truck or other mechanical assist unit to move the server
from one location to another.
v
CAUTIONS
ELECTROSTATIC DISCHARGE (ESD) AND ESD PROTECTION: ESD can
damage disk drives, add-in boards, and other components. This server can
withstand normal levels of environmental ESD while hot-swapping SCSI hard
disk drives. However, we recommend doing all procedures in this manual
only at an ESD-protected workstation. If one is not available, you can
provide some ESD protection by wearing an antistatic wrist strap attached to
chassis ground of the server—any unpainted metal surface—when handling
components.
HANDLING BOARDS AND MODULES: Boards and modules can be extremely
sensitive to ESD and always require careful handling. After removing a board
or module from its protective wrapper or from the server, place it
component-side up on a nonconductive, static-free surface. If you place the
baseboard on a conductive surface, the battery leads can short out. If they do,
this will result in a loss of CMOS data and will drain the battery. Do not slide
a board or module over any surface.
SERVER COOLING AND AIRFLOW: Operating the server with the covers
removed can damage the server components. For proper cooling and airflow,
always replace the covers before turning on the server.
vi
Equipment Rack Precautions
WARNINGS
ANCHOR THE EQUIPMENT RACK: The equipment rack must be anchored
to an unmovable support to prevent it from falling over when one or more
servers are extended in front of it on slide assemblies. The anchors must
be able to withstand a force of up to 113 kg (250 lbs). You must also
consider the weight of any other device installed in the rack.
MAIN AC POWER DISCONNECT: You are responsible for installing an AC
power disconnect for the entire rack unit. This main disconnect must be
readily accessible, and it must be labeled as controlling power to the
entire unit, not just to the server(s).
GROUNDING THE RACK INSTALLATION: To avoid the potential for an
electrical shock hazard, you must include a third wire safety grounding
conductor with the rack installation. If server power cords are plugged
into AC outlets that are part of the rack, then you must provide proper
grounding for the rack itself. If server power cords are plugged into wall
AC outlets, the safety grounding conductor in each power cord provides
proper grounding only for the server. You must provide additional,
proper grounding for the rack and other devices installed in it.
Overcurrent protection: The server is designed for an AC line voltage
source with up to 20 amperes of overcurrent protection. If the power
system for the equipment rack is installed on a branch circuit with more
than 20 amperes of protection, you must provide supplemental protection
for the server. If more than one server is installed in the rack, the power
source for each server must be from a separate branch circuit. The
overall current rating of a server configured with three power supplies is
under 12 amperes.
CAUTIONS
Temperature: The operating temperature of the server, when installed in an
equipment rack, must not go below 5 °C (41 °F) or rise above 35 °C (95 °F).
Extreme fluctuations in temperature can cause a variety of problems in your
server.
Ventilation: The equipment rack must provide sufficient airflow to the front
of the server to maintain proper cooling. It must also include ventilation
sufficient to exhaust a maximum of 4,100 Btu's per hour for the server. The
rack selected and the ventilation provided must be suitable to the environment
in which the server will be used.

Introduction
The SC450NX MP server is designed to either stand upright (pedestal mode) or be mounted in a rack
(rack mode). Figures 1 and 2 on page 12 show examples of these configurations. Before operation,
you must purchase an adapter kit to configure the server for one of the two modes. If you have
already created a pedestal server but now want to install it in a rack, you will also need an adapter
kit.
If you have not already purchased a kit for your particular task, contact your customer service
representative for details.
This guide explains three processes:
1. Installing your server in an EIA-compatible 19-inch equipment rack
2. Mounting your server in a pedestal configuration
3. Changing from pedestal to rack mode
Before starting, please read “Safety Guidelines” on page v.

Prepare the Server
Before you can install the server in the 19-inch equipment rack, you must install a bezel, handles, and
the small bars of the slide assemblies onto the sides of the server.
Attaching the Bezel Frame and Door
To be installed in a rack, the server needs a bezel frame with rectangular cutouts where the chassis
handles fit.
1. Attach the bezel frame by inserting the tabs at the corner of the frame into their corresponding
rectangular slots on the chassis.
2. Attach the bezel door: with the door all the way open (down, as the server lay as it would when
inserted in a rack), align the tabs on the door with their corresponding hinge loops on the chassis;
slide the door to the right to engage the tabs in the loops.
Attach the Chassis Handles
Before you can attach the chassis handles, the server must be on its side, in the horizontal position in
which you will slide it into the rack. If the server is not already in the proper position, you must
move it. See step one, below.
WARNING
AVOID INJURY: To avoid personal injury when unpacking the server, use
only a mechanical assist unit to lift it off the shipping pallet. The
minimum server configuration weighs 38 kg (85 lbs); the maximum weighs
45 kg (100 lbs).
Do not attempt to lift or move the server by the handles on the power
supplies.
Use only a hand-truck or other mechanical assist unit to move the server
from one location to another.
1. If the server is not already in the proper position, then face the front of the server and, with the
help of a mechanical assist unit, carefully tip it onto its side. The long front edges (19 inches)
should now be horizontal; the short front edges (12.25 inches) should now be vertical, with the
front-panel LEDs at the top left and the hard drive bays at the bottom right of the front panel.
The bezel frame has rectangular cutouts on its edges where the chassis handles fit; you should be
able to see two threaded holes in that cut-out space where the handles attach to the chassis.
2. Orient each handle so the two screw holes on the long edge of each handle align with the threaded
holes in the chassis. Because the bezel frame’s cutouts act as guides, the handles can be installed
in only one way.
3. Use four screws from the kit to attach the handles to the chassis.
14
Attach the Small Bar of the Slide Assembly to the Server
See Figure 4.
1. Remove four screws from the kit.
2. While facing the side of the server, orient the small bar so that the flat side faces the top and the
right-angle end faces the front of the server.
3. Align the first hole in the right-angle end of the bar with the first threaded hole in the side of the
chassis.
4. Insert a screw through the hole in the bar and into the chassis wall. Then loosely tighten the
screw.
5. Align the rest of the holes in the bar with the remaining three threaded holes along the side of the
chassis.
6. Insert three more screws through the bar and into the threaded holes in the chassis wall. Then
tighten all four screws firmly (6.0 inch-pounds).
7. Install the remaining small bar on the other side of the chassis by repeating steps 1–6 above.

Prepare the Equipment Rack
Before you can install the server in the 19-inch equipment rack, you must attach the center bar and
large outer bar assemblies to the vertical rails of the rack.
Attach the Right-angle Extension Brackets to the Equipment
Rack
NOTE
/
Mounting holes in the vertical rails of equipment racks are commonly spaced
in a 5/8 x 5/8 x 1/2-inch sequence. Perform the following steps carefully;
brackets must be mounted with precision to allow room for the next server you
install in a rack.
See Figure 5.
1. Remove a right-angle extension bracket, two screws, and a bar nut from the kit.
2. While facing the front or back of the rack, orient the right-angle extension bracket so that the
short side with the four mounting holes is facing toward the outside edge of the vertical rail.
3. Position the bracket behind the mounting holes in the vertical rail.

4. With a pencil, mark the top and bottom hole locations of the bracket on both sides of the vertical
rail; no hole numbers are printed on the rail.
5. Insert a screw through the marked top hole in the rail and through the top hole in the bracket.
Place a bar nut on the screw and loosely tighten it. Repeat for the marked bottom hole.
6. Install the three remaining right-angle extension brackets on the other three vertical rails by
repeating steps 1–5 above.
16
Attach the Center Bar and Large Outer Bar Assemblies to the
Equipment Rack
See Figure 6.
1. Orient a center bar and large outer bar assembly so that the flat side is facing toward the
brackets attached to the vertical rails and the safety latch on the center bar is near the back of the
rack.
2. Press the flat side of the outer bar into the U-shaped sections of the brackets.
3. Slide the assembly toward the front of the rack until the end of the outer bar is flush with the end
of the U-shaped section of the front bracket.
4. Gently slide the center bar toward the front of the rack, and position the oblong slot in it over the
first hole in the large outer bar. Insert a screw through the hole in the bar and the first hole in the
front bracket. Place a lock washer and a nut on the screw, and loosely tighten it.
5. Position the oblong slot in the center bar over the third hole back from the front of the large outer
bar. Insert an 8-32 screw through the hole and the oblong slot in the front bracket. Place a lock
washer and an 8-32 nut on the screw, and loosely tighten it.
6. The back bracket has two holes and three slots in it. This end of the outer bar has four holes in
it. Which holes and slots you use depend on the depth of the equipment rack. After fitting the
bar into the bracket, insert two screws through the holes in the bar and the appropriate oblong
slots in the bracket. Place a lock washer and a nut on each screw, and loosely tighten them.
7. Ensure that the brackets and bars are positioned correctly in the rack. Then tighten all screws
firmly (6.0 inch-pounds).

extending from the chassis wall. Orient the chassis foot to align these features with their
corresponding parts of the chassis wall.
3. Insert the end of the foot with the two slots under the lip at the edge of the chassis.
4. Swing the end of the foot with the screw hole to the chassis wall; attach that end of the foot with
one screw.
5. Repeat for the second chassis foot.
Figure 8. Installing Chassis Feet
Install the Top and Side Covers
1. Observe the safety guidelines on page v.
2. Orient the top cover over the server so that the built-in handle faces the rear panel.
3. The cover has a row of tabs that fit a row of slots in the chassis. With the front edge of the
cover approximately one inch behind the front of the chassis, push the cover straight down so the
cover’s tabs fit into the chassis’ slots.
4. With an even push, slide the cover forward to engage the tabs in their slots until the cover stops.
The back of the cover should be flush with the back of the server.
5. Fasten the top cover with one screw; the side cover requires two screws.
6. Repeat these steps to install the side cover.
21
Install Bezel Frame and Door
1. Attach the bezel frame by inserting the tabs at the corner of the frame into their corresponding
rectangular slots on the chassis.
2. Attach the bezel door: with the door all the way open (left, as it stands upright in a pedestal
mount), align the tabs on the door with their corresponding hinge loops on the chassis; slide the
door down to engage the tabs in the loops.
22
Changing from Pedestal to Rack
To change your server from pedestal mode to rack mode, you must complete two basic steps:
removing the components of the pedestal mount, then configuring the server for a rack mount.
Because configuring for a rack mount was described in an earlier section (page 13), this section
covers only a few details unique to your task and refers you to the earlier section for the rest of the
required information.
Before starting, please read “Safety Guidelines” on page v.
Prepare the Slide Assemblies
See page 13.
Remove the Covers
1. Observe the safety guidelines on page v.
2. Turn off all peripheral devices connected to the server.
3. Turn the server power off with the on/off power switch on the front of the server AND unplug all
AC power cords.
4. Label and disconnect all peripheral cables attached to the I/O panel on the back of the server.
Figure 9. Screw Locations, Top and Side Covers
5. Remove and save the single screw from the back of the TOP cover.
6. Place the fingertips of your hand under the built-in handle on the back of the cover.
7. Using an even pull, slide the cover backward, about an inch, until it stops.
8. Pull the entire cover upward, straight away from the chassis, to disengage the rows of tabs from
the notches in the chassis. Set the cover aside.
9. Remove and save the two screws from the back of the SIDE cover.
10. Remove the side cover in the same manner as the top and access covers: pull the cover back
using the built-in handle, then lift it away.
23
Exchange the Bezel Frame
To be installed in a rack, the server needs a new bezel frame with rectangular cutouts where the
chassis handles fit. You need to remove the old bezel frame and install the new one from the rack kit.
1. Remove the bezel door: with the door open all the way (to the left), lift it upward to release it
from its hinges on the chassis.
2. Remove the bezel frame: disengage the tabs that attach the bezel frame to the chassis by pressing
each tab toward the center of the chassis while pulling the frame away.
3. Attach the new bezel frame by reinserting the tabs into their corresponding rectangular slots on
the chassis.
4. Reattach the bezel door to its hinges on the chassis.
5. Continue the procedures beginning with “Attach the Chassis Handles” (page 14) through “Install
the Server in the Rack” (page 18).
