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, famailiar 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, file 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 venilated. Avoid areas where heat,

electrical noise and eletromagnetic fields are generated.

You will also need it placed near at least one grounded power outlet. When config

-

ured, the SC503 chassis includes one power supply.

2-3 Preparing for Setup

The SC503 Chassis bolts directly to a rack and includes the 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.

SC503 Chassis Manual

2-2

2-4 Electrical Safety Precautions

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

and the SC503 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 floppy drives (not necessary for hot swappable drives).

When disconnecting power, you should first 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 specifically 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.

Chapter 2: System Safety

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 sufficient 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 specifically 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.

•

•

•

•

•

•

•

SC503 Chassis Manual

2-4

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.

The SC503 Chassis has a 200 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.

The SC503 chassis has one power supply. In the unlikely event that the power

supply unit fails, the system will shut down and you will need to change the power

supply unit.

New units can be ordered directly from Supermicro (see contact information in the

Preface).

Replacing the Power Supply

Unplug all power leading to the chassis.

Disconnect all wiring from the power supply.

Remove the four screws which hold the power supply in the chassis. The two

rear mounting screws are located on the back of the power supply. The two

bottom mounting screws are accessed on the underside of the chassis and

Rack Installation

5-1 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 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 file 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 fields 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. 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

sufficient airflow and ease in servicing.

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

equipment rooms, service closets and similar environments).

Rack Precautions

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

the floor 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 first, 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.

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 Airflow

Equipment should be mounted into a rack so that the amount of airflow 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).

Front Panel to the Motherboard

The SC503 chassis includes a cable to connect the chassis front panel to the

motherboard. If your motherboard uses a different connector, use the following list

to find a compatible cable.

The SNK-P00A4 active heatsink may only be used on specific motherboards, due

to its larger 4" x 4" size. This is particularly important in systems utilizing Intel

Celeron 400 series platforms. To ascertain which heatsink is appropriate for your

motherboard, refer to the Supermicro Web site at http://www.supermicro.com.

Extending Power Cables

Although Supermicro chassis are designed with to be efficient and cost-effective,

some compatible motherboards have power connectors located in different areas.

To use these motherboards you may have to extend the power cables to the mother

boards. To do this, use the following chart as a guide.

1U Active Heatsink (SNK-P0032A4)

It is critical to choose the correct heatsink for your motherboard, that will fit in the

SC503 chassis.

Intel Celeron 400 seriew (35W) platform: Active heatsink SNKP0032A4

Low power platforms under 20W: Passive heatsink SNKP0016P
