2-1

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 order given should enable you to have your chassis setup and

operational within a minimal amount of time. This quick set up 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.

You will also need it placed near at least one grounded power outlet. When cong-

ured, the SC818G chassis includes one power supply.

2-3 Preparing for Setup

The SC818G chassis includes a set of rail assemblies, including mounting brackets

and mounting screws you will need to install the systems into the rack. Please read

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

2-4 Electrical Safety Precautions

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

and the SC818G 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.•

SC818G Chassis Manual

2-2

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 onboard •

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.

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.

2-3

Chapter 2: System Safety

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.

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

in use.

SC818G Chassis Manual

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

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

the serverboard.

Permanent and Optional Standoffs

Standoffs prevent short circuits by securing space between the motherboard and

the chassis surface. The SC818G chassis includes permanent standoffs in loca-

tions used by most motherboards. These standoffs accept the rounded Phillips head

screws included in the SC818G accessories packaging.

Some motherboard require additional screws for heatsinks, general components

and/or non-standard security. Optional standoffs are included to these mother-

boards. To use an optional standoff, you must place the hexagonal screw through

the bottom of the chassis and secure the screw with the hexagon nut (rounded

Eight heavy-duty fans provide cooling for the chassis. These fans circulate air

through the chassis as a means of lowering the chassis' internal temperature.

The chassis includes counter-rotating fans. Each fan unit is actually made up of two

fans joined back-to-back, which rotate in opposite directions. This counter-rotating

action generates exceptional airow and works to dampen vibration levels.

Fan Numbering in the BIOS

In the unlikely event of a fan failure, the failed system fan can be identied through

the BIOS, by utilizing the fan numbering system shown below. These numbers are

also imprinted on the oor of the chassis.

Chapter 6

Rack Installation

6-1 Overview

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

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

operational within a minimum amount of time.

6-2 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

Precautions in the next section.

6-3 Preparing for Setup

The box your chassis was shipped in should include two sets of rail assemblies,

two rail mounting brackets and the mounting screws you will need to install the

system into the rack. Please 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 the back of the rack to allow for •

sufcient airow and ease in servicing.

This product is for installation only in a Restricted Access Location (dedicated •

equipment rooms, service closets and the like).

SC818G Chassis Manual

6-2

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 si-•

multaneously 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 • before you install the

rails.

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 hot plug hard drives and power supply modules to cool before touch-•

ing them.

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

closed when not servicing to maintain proper cooling.

Chapter 6: 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 (i.e. the use of power

strips, etc.).

SC818G Chassis Manual

6-4 Rack Mounting Instructions

This section provides information on installing the SC818G chassis into a rack unit

with the quick-release rails provided. There are a variety of rack units on the market,

which may mean that the assembly procedure will differ slightly. You should also

refer to the installation instructions that came with the rack unit you are using.

NOTE: This rail will t a rack between 26" and 33.5" deep.

Identifying the Sections of the Rack Rails

The chassis package includes two quick-release rail assemblies in the rack mounting

kit. Each assembly consists of two primary sections: an inner xed chassis rail and

inner rail extention that secure directly to the chassis, and an outer rail assembly

that secures directly to the rack itself.

Installing the Inner Rail Extensions

The SC818G chassis includes a set of inner rails in two sections: inner rails (A)

and inner rail extensions (B), which are attached to the chassis. The inner rails are

preattached and do not interfere with normal use of the chassis if you decide not

to use a server rack. Attach the inner rail extensions stabilize the chassis within

the rack.

Installing the Inner Rail Extensions

Place the inner rail extensions (B) over the preattached inner rails (A) which 1.

are attached to the side of the chassis. Align the hooks of the inner rail with

the rail extension holes. Make sure the extension faces "outward" just like the

inner rail.

Slide the extension toward the front of the chassis.2.

Secure the chassis with screws as illustrated.3.

Repeat steps 1-3 for the other inner rail extension.4.

To install the chassis into a Telco (post) type rack, use two L-shaped brackets (Op-

tional with the MCP-290-00016-0N) on either side of the chassis (four total). First,

determine how far follow the chassis will extend out the front of the rack. Larger

chassis should be positioned to balance the weight between front and back. If a

bezel is included on your chassis, remove it. Then attach the two front brackets to

each side of the chassis, then the two rear brackets positioned with just enough

space to accommodate the width of the Telco rack. Finish by sliding the chassis

into the rack and tightening the brackets to the rack.

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.
