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.

supermicro.com/support/rma/).

Whenever possible, repack the chassis in the original Supermicro carton, using the

original packaging material. If these are no longer available, be sure to pack the

chassis securely, using packaging material to surround the chassis so that it does

not shift within the carton and become damaged during shipping.

This warranty only covers normal consumer use and does not cover damages in

-

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

maintenance of products.

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

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 con

-

figured, the SC846 chassis includes one power supply. "R" models (i.e. SC846S-

R650V Chassis) include a redundant power supply and require two grounded

outlets.

2-3 Preparing for Setup

The SC846 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 SC846 from damage:

SC846 Chassis Manual

2-2

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.

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.

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 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.

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.

SC846 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.

Chapter 3 System Interface

Chapter 3

System Interface

3-1 Overview

There are several LEDs on the control panel as well as others on the drive carriers

to keep you constantly informed of the overall status of the system as well as the

activity and health of specific components. Most SC846 models are two buttons

on the chassis control panel: a reset button and an on/off switch. This chapter ex-

plains the meanings of all LED indicators and the appropriate response you may

need to take.

SC846 Chassis Manual

3-2

3-3 Control Panel LEDs

The control panel located on the front of the SC846 chassis has five LEDs. These

LEDs provide you with critical information related to different parts of the system.

This section explains what each LED indicates when illuminated and any corrective

action you may need to take.

Power: The main power button is used to apply or remove power from the power

supply to the server system. Turning off system power with this button removes

the main power but keeps standby power supplied to the system. Therefore, you

must unplug system before servicing.

Reset: The reset button is used to reboot the system.

3-2 Control Panel Buttons

There are two push-buttons located on the front of the chassis. These are (in order

from left to right) a reset button and a power on/off button.

Overheat /Fan Fail:

When this LED flashes, it indicates a fan failure. When con-

tinuously on (not flashing) it indicates an overheat condition, which may be caused

by cables obstructing the airflow in the system or the ambient room temperature

being too warm. Check the routing of the cables and make sure all fans are pres-

ent and operating normally. You should also check to make sure that the chassis

covers are installed. Finally, verify that the heatsinks are installed properly. This

LED will remain flashing or on as long as the overheat condition exists.

3-3

Chapter 3 System Interface

Power: Indicates power is being supplied to the system's power supply units. This

LED should normally be illuminated when the system is operating.

HDD: Indicates IDE channel activity. SAS/SATA drive, SCSI drive, and/or DVD-

ROM drive activity when flashing.

NIC1:

Indicates network activity on GLAN1 when flashing.

NIC2:

Indicates network activity on GLAN2 when flashing.

!

Power Failure: When this LED flashes, it indicates a failure in the power supply.

SC846 Chassis Manual

3-4

3-4 Drive Carrier LEDs

Your chassis uses SAS/SATA or SCSI drives, but not both.

SAS/SATA Drives

Each SAS/SATA drive carrier has two LEDs.

Green: Each Serial ATA drive carrier has a green LED. When illuminated, this

green LED (on the front of the SATA drive carrier) indicates drive activity. A

connection to the SATA backplane enables this LED to blink on and off when

that particular drive is being accessed.

Red: The red LED to indicate an SAS/SATA drive failure. If one of the SAS/SATA

drives fail, you should be notified by your system management software.

SCSI Drives

Each SCSI drive carrier has two LEDs.

Green: When illuminated, the green LED on the front of the SCSI drive carrier

indicates drive activity. A connection to the SCSI SCA backplane enables this

LED to blink on and off when that particular drive is being accessed.

Red: The SAF-TE compliant backplane activates the red LED to indicate a drive

failure. If one of the SCSI drives fail, you should be notified by your system

management software.

The SC846 Chassis has a 900 watt, high-efficiency redundant 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 supplies can be changed without powering down the system.

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

Preface).

Chapter 5

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 within a minimum 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 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

sufficient airflow and ease in servicing.

•

•

SC846 Chassis Manual

5-2

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

equipment rooms, service closets and the like).

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

-

ing them.

Warnings and Precautions!

!

!

5-3

Chapter 5 Rack Installation

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

closed when not servicing 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 (i.e. the use of power

strips, etc.).

5-4 Rack Mounting Instructions

Rack Rails Assembly

This section provides information on installing the SC846 chassis into a rack unit

with the 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 fit a rack between 26" and 33.5" deep.

Identifying the Inner Rack Rails

The chassis package includes a rack rail assembly in the rack mounting kit. Each

assembly consists of an inner rail that secures to the chassis and an outer rail that

is attached directly to the rack.

Safety Guidelines

To avoid personal injury and property damage, carefully follow all the safety
steps listed below when accessing your system or handling the compo

-

nents.

D-1 ESD Safety Guidelines

Electric Static Discharge (ESD) can damage electronic components. To prevent dam-

age to your system, it is important to handle it very carefully. The following measures

are generally sufficient to protect your equipment from ESD.

Use a grounded wrist strap designed to prevent static discharge.

Touch a grounded metal object before removing a component from the antistatic

bag.

Handle the RAID card by its edges only; do not touch its components, peripheral

chips, memory modules or gold contacts.

When handling chips or modules, avoid touching their pins.

Put the card and peripherals back into their antistatic bags when not in use.

D-2 General Safety Guidelines

Always disconnect power cables before installing or removing any components

from the computer, including the backplane.

Disconnect the power cable before installing or removing any cables from the

backplane.

Make sure that the backplane is securely and properly installed on the mother

-

board to prevent damage to the system due to power shortage.

D-6 Front Jumper Locations and Pin Definitions

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 identified 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.

Cascading allows the system to access data at a faster rate by allowing several

backplanes to share resources to reduce latency time.

The first backplane in a cascaded system requires a motherboard and HBA. Other

servers require a power control card with no motherboard and no HBA. For more

information, see the SC846 Chassis Manual available at www.supermicro.com.
