curred in shipping or from failure due to the alteration, misuse, abuse or improper

maintenance of products.

During the warranty period, contact your distributor rst for any product problems.

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-

gured, the SC825 chassis includes one power supply. "R" models (i.e. SC825S-

R700V Chassis) include a redundant power supply and require two grounded

outlets.

2-3 Preparing for Setup

The SC825 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.

SC825 Chassis Manual

2-2

2-4 Electrical Safety Precautions

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

and the SC825 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 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.

2-3

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.

SC825 Chassis Manual

2-4

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 serverboard 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.

Permanent and Optional Standoffs

Standoffs prevent short circuits by securing space between the motherboard and

the chassis surface. The SC825 chassis includes permanent standoffs in locations

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

screws included in the SC825 accessories packaging.

Some motherboards 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 the chassis and secure the screw with the hexagon nut (rounded side

Chapter 5: Chassis Setup and Maintenance

Depending on your chassis model, the SC825 Chassis has a 560, 700, 710 or 720

Watt power supply. This power supply is auto-switching capable. This enables it to

automatically sense and operate at a 100v to 240v input voltage. An amber light

will be illuminated on the power supply when the power is off. An illuminated green

light indicates that the power supply is operating.

Power Supply Failure

SC825 chassis models have either one or two (redundant) power supplies. In the

unlikely event that the power supply unit fails, if you have a single power supply, the

system will shut down and you will need to replace the power supply unit.

SC825 chassis models which include a redundant power supply, will allow for the

power supply to be replaced without powering down the system.

Replacement units can be ordered directly from Supermicro (see contact informa-

tion in the Preface).

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 Pre-

cautions 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).

SC825 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.).

6-4 Rack Mounting Instructions

This section provides information on installing the SC825 chassis into a rack unit

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

which may mean 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.

Separating the Sections of the Rack Rails

The chassis package includes two rail assemblies in the rack mounting kit. Each

assembly consists of two sections: an inner xed chassis rail that secures directly

to the server chassis and an outer xed rack rail that secures directly to the rack

itself.

C-7 FrontJumperLocationsandPinDenitions

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.
