1-5 Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is required be-

fore any warranty service will be rendered. You can obtain service by calling your

vendor for a Returned Merchandise Authorization (RMA) number. When returning

to the manufacturer, the RMA number should be prominently displayed on the

outside of the shipping carton, and mailed prepaid or hand-carried. Shipping and

handling charges will be applied for all orders that must be mailed when service

is complete.

For faster service, RMA authorizations may be requested online (http://www.

Chapter 2: System Safety

Chapter 2

System Safety

2-1 Overview

This chapter provides a quick setup checklist to get your chassis up and running.

Following the steps in the order given should enable you to have your chassis set up

and operational within a minimal amount of time. This quick setup assumes that you

are an experienced technician, familiar with common concepts and terminology.

2-2 Warnings and Precautions

You should inspect the box the chassis was shipped in and note if it was damaged

in any way. If the chassis itself shows damage, le a damage claim with carrier

who delivered your system.

Decide on a suitable location for the rack unit that will hold that chassis. It should

be situated in a clean, dust-free area that is well ventilated. Avoid areas where heat,

electrical noise and electromagnetic elds are generated.

The system must be placed near at least one grounded power outlet. When con-

gured, the SC743 chassis includes at least one power supply, "R" model chassis

may include up to three redundant power supplies.

2-3 Preparing for Setup

The SC743 chassis may stand as a tower or bolt directly to a rack. The mounting

screws you will need to install the systems into the rack are included. Please read

this manual in its entirety before you begin the installation procedure.

2-1

SC743 Chassis Manual

2-4 Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from harm

and the SC743 from damage:

Be aware of the locations of the power on/off switch on the chassis as well •

as the room’s emergency power-off switch, disconnection switch or electrical

outlet. If an electrical accident occurs, you can then quickly remove power from

the system.

Do not work alone when working with high-voltage components.•

Power should always be disconnected from the system when removing or in-•

stalling main system components, such as the serverboard, memory modules

and the DVD-ROM and oppy drives (not necessary for hot-swappable drives).

When disconnecting power, you should rst power down the system with the

operating system and then unplug the power cords from all the power supply

modules in the system.

When working around exposed electrical circuits, another person who is fa-•

miliar with the power-off controls should be nearby to switch off the power, if

necessary.

Use only one hand when working with powered-on electrical equipment. This •

is to avoid making a complete circuit, which will cause electrical shock. Use

extreme caution when using metal tools, which can easily damage any electrical

components or circuit boards they come into contact with.

Do not use mats designed to decrease electrostatic discharge as protection from •

electrical shock. Instead, use rubber mats that have been specically designed

as electrical insulators.

The power supply power cord must include a grounding plug and must be •

plugged into grounded electrical outlets.

Serverboard battery: CAUTION - There is a danger of explosion if the on-board •

battery is installed upside down, which will reverse its polarities. This battery

must be replaced only with the same or an equivalent type recommended by

the manufacturer. Dispose of used batteries according to the manufacturer’s

instructions.

2-2

Chapter 2: System Safety

Please handle used batteries carefully. Do not damage the battery in any way; •

a damaged battery may release hazardous materials into the environment. Do

not discard a used battery in the garbage or a public landll. Please comply

with the regulations set up by your local hazardous waste management agency

to dispose of your used battery properly.

DVD-ROM laser: CAUTION - This server may have come equipped with a •

DVD-ROM drive. To prevent direct exposure to the laser beam and hazardous

radiation exposure, do not open the enclosure or use the unit in any uncon-

ventional way.

2-5 General Safety Precautions

Keep the area around the chassis clean and free of clutter.•

Place the chassis top cover and any system components that have been re-•

moved away from the system or on a table so that they won’t accidentally be

stepped on.

While working on the system, do not wear loose clothing such as neckties and •

unbuttoned shirt sleeves, which can come into contact with electrical circuits or

be pulled into a cooling fan.

Remove any jewelry or metal objects from your body, which are excellent metal •

conductors that can create short circuits and harm you if they come into contact

with printed circuit boards or areas where power is present.

After accessing the inside of the system, close the system back up and secure •

it to the rack unit with the retention screws after ensuring that all connections

have been made.

2-6 System Safety

Electrostatic discharge (ESD) is generated by two objects with different electrical

charges coming into contact with each other. An electrical discharge is created to

neutralize this difference, which can damage electronic components and printed

circuit boards. The following measures are generally sufcient to neutralize this

difference before contact is made to protect your equipment from ESD:

Do not use mats designed to decrease electrostatic discharge as protection from •

electrical shock. Instead, use rubber mats that have been specically designed

as electrical insulators.

2-3

SC743 Chassis Manual

Use a grounded wrist strap designed to prevent static discharge.•

Keep all components and printed circuit boards (PCBs) in their antistatic bags •

until ready for use.

Touch a grounded metal object before removing any board from its antistatic •

bag.

Do not let components or PCBs come into contact with your clothing, which may •

retain a charge even if you are wearing a wrist strap.

Handle a board by its edges only; do not touch its components, peripheral chips, •

memory modules or contacts.

When handling chips or modules, avoid touching their pins.•

Put the backplane and peripherals back into their antistatic bags when not in •

use.

For grounding purposes, make sure your computer chassis provides excellent •

conductivity between the power supply, the case, the mounting fasteners and

the serverboard.

Chapter 5

Rack Installation

5-1 Overview

This chapter provides instructions on installing the chassis into a rack. Following

these steps in the order given should enable you to have the system installed in a

minimal amount of time.

5-2 Unpacking the System

You should inspect the box the chassis was shipped in, and note if it was damaged

in any way. If the chassis itself shows damage, you should le a damage claim with

the carrier who delivered it.

Decide on a suitable location for the rack unit that will hold your chassis. It should

be situated in a clean, dust-free area that is well ventilated. Avoid areas where

heat, electrical noise and electromagnetic elds are generated. You will also need

it placed near a grounded power outlet. Be sure to read the Rack and Server Pre-

cautions in the next section.

5-3 Preparing for Setup

The box your chassis was shipped in should include four mounting screws, which

you will need if you intend to install the system into a rack. Read this section in

its entirety before you begin the installation procedure outlined in the sections that

follow.

Choosing a Setup Location

Leave enough clearance in front of the rack to enable you to open the front •

door completely (~25 inches).

Leave approximately 30 inches of clearance in back of the rack to allow for •

sufcient airow and ease in servicing.

5-1

SC743 Chassis Manual

!

!

This product is only to be installed in a Restricted Access Location (dedicated •

equipment rooms, service closets and similar environments).

Warnings and Precautions!

Rack Precautions

Ensure that the leveling jacks on the bottom of the rack are fully extended to •

the oor with the full weight of the rack resting on them.

In single rack installation, stabilizers should be attached to the rack.•

In multiple rack installations, the racks should be coupled together.•

Always make sure the rack is stable before extending a component from the •

rack.

You should extend only one component at a time. Extending two or more simul-•

taneously may cause the rack to become unstable.

General Server Precautions

Review the electrical and general safety precautions that came with the com-•

ponents you are adding to your chassis.

Determine the placement of each component in the rack.•

Install the heaviest server components on the bottom of the rack rst, and then •

work up.

Use a regulating, uninterruptible power supply (UPS) to protect the server from •

power surges, voltage spikes and to keep your system operating in case of a

power failure.

Allow the hard drives and power supply modules to cool before touching •

them.

Always keep the rack's front door, all panels and all components on the servers •

closed when not servicing, in order to maintain proper cooling.

5-2

Chapter 5: Rack Installation

Rack Mounting Considerations

Ambient Operating Temperature

If installed in a closed or multi-unit rack assembly, the ambient operating tempera-

ture of the rack environment may be greater than the ambient temperature of the

room. Therefore, consideration should be given to installing the equipment in an

environment compatible with the manufacturer’s maximum rated ambient tempera-

ture (TMRA).

Reduced Airow

Equipment should be mounted into a rack so that the amount of airow required

for safe operation is not compromised.

Mechanical Loading

Equipment should be mounted into a rack so that a hazardous condition does not

arise due to uneven mechanical loading.

Circuit Overloading

Consideration should be given to the connection of the equipment to the power

supply circuitry and the effect that any possible overloading of circuits might have

on overcurrent protection and power supply wiring. Appropriate consideration of

equipment nameplate ratings should be used when addressing this concern.

Reliable Ground

A reliable ground must be maintained at all times. To ensure this, the rack itself

should be grounded. Particular attention should be given to power supply connec-

tions other than the direct connections to the branch circuit (for example, the use

of power strips, and other devices).

Explanation of Jumpers

To modify the operation of the backplane,

jumpers can be used to choose between

optional settings. Jumpers create shorts

between two pins to change the function

of the connector. Pin 1 is identied with

a square solder pad on the printed circuit

board.

Note: On two pin jumpers, "Closed" means

the jumper is on and "Open" means the

jumper is off the pins.
