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 set up

and operational within a minimal amount of time. This quick setup 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, 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 venilated. Avoid areas where heat,

electrical noise and eletromagnetic elds are generated.

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

ured, the SC808 chassis includes one power supply.

2-3 Preparing for Setup

The SC808 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 SC808 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.•

SC808 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.

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.

2-3

Chapter 2: System Safety

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.

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.

SC808 Chassis Manual

2-4

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 I/O shield holds the motherboard ports in place. The I/O shield does not require

installation, however, the motherboard must match up with the I/O shield.

Permanent and Optional Standoffs

Standoffs prevent short circuits by securing space between the motherboard and

the chassis surface. The SC808 chassis includes permanent standoffs in locations

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

included in the SC808 accessories packaging.

Some motherboards require additional screws for heatsinks, general components

and for stability. Optional standoffs are used for these motherboards.

To use an optional standoff, you must place a hexagonal screw through the bottom

the chassis and secure the screw with the hexagonal nut (rounded side up).

Depending upon the conguration of the motherboard being used, it is also pos-

sible that some of the optional standoffs which are pre-installed in the chassis, may

need to be removed.

Six fans provide cooling for the chassis. These fans circulate air through the chassis

as a means of lowering the chassis internal temperature. The SC808 system fans

are hot-swappable. There is no need to power-down the system when switching

fans.

5-7 System Fans

Figure 5-10: System Fan

Changing a System Fan

If necessary, open the chassis while the power is running to determine which 1.

fan has failed. (Never run the server for an extended period of time with the

chassis open.)

Remove the failed fan's power cord from the serverboard. 2.

Lift the fan from the chassis.3.

Place the new fan into the vacant space in the housing while making sure the 4.

arrows on the top of the fan (indicating air direction) point in the same direc-

tion as the arrows on the other fans. Make sure all four of the fan's rubber

feet are in place.

Conrm that the fan is working properly before replacing the chassis cover.5.

Depending on your chassis model, the SC808 Chassis has a 780, 980 or 1200

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 Replacement

The SC808 chassis utilizes one power supply. In the unlikely event that the power

supply unit must be replaced, the system will shut down. Replacement units can be

ordered directly from Supermicro (see contact information in the Preface).

Chapter 6

Rack Installation

6-1 Overview

This chapter provides a quick setup checklist to install the chassis into a rack. Fol-

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

within a minimal 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).

SC808 Chassis Manual

6-2

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 • 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-swappable hard drives and the power supply module to cool •

before touching them.

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

closed when not servicing to maintain proper cooling.

6-3

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 SC808 chassis into a rack unit

with the 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.

Identifying the Sections of the Rack Rails

The chassis package includes two rack 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.

Chapter 6: Rack Installation

Figure 6-2: Installing the Inner Rail Extension

Installing the Inner Rail Extension

The SC808 chassis includes a set of inner rails in two sections: Inner rails and inner

rail extensions. 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 extension

to stabilize the chassis within the rack.

Installing the Inner Rails

Place the inner rack extensions on the side of the chassis aligning the hooks 1.

of the chassis with the rail extension holes. Make sure the extension faces

"outward" just like the preattached inner rail.

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

Secure the chassis with two screws as illustrated.3.

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

Installing the Outer Rails to the Rack

Attach the short bracket to the outside of the long bracket. You must align the 1.

pins with the slides. Also, both bracket ends must face the same direction.

Adjust both the short and long brackets to the proper distance so that the rail 2.

ts snugly into the rack.

Secure the long bracket to the front side of the outer rail with two M5 screws 3.

and the short bracket to the rear side of the outer rail with three M5 screws.

Repeat steps 1-4 for the left outer rail.4.
