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.

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.

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 Slide Assemblies

See Figure 3.

1. Remove the slide assemblies from the kit.

2. Orient a slide assembly so that the smallest outer bar is facing down.

3. Fully extend the telescoping slide assembly until the center bar hits the safety latch on the small

outer bar (all three overlapping bars will be visible).

4. Grasp the small outer bar with your right hand so that your thumb is on the safety latch of the

small outer bar.

5. Press and hold the safety latch down, and at the same time, grasp the large outer bar with your

left hand.

6. Pull the small bar out of the center bar; this takes a little force to separate them. Set the small

bar aside to attach to the chassis in a later step.

7. Orient the center bar and large outer bar assembly so that the center bar is facing up.

8. Grasp the center bar with your right hand and the large outer bar with your left hand so that your

left-hand thumb is on the safety latch of the center bar.

9. Press the safety latch, and slide the bars together. Set the center bar and large outer bar

assembly aside to attach to the equipment rack in a later step.

10. Prepare the other slide assembly by repeating steps 2–9 above.

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.

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.

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).
