1-5 Returning Merchandise for Service
A receipt or copy of your invoice marked with the date of purchase is required before 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.

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 configured, the SC846 chassis includes one power supply. "R" models 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:
2-1
SC846 Chassis Manual
•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 unconventional way.
2-2
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.
2-3
SC846 Chassis Manual
•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 have two buttons
on the chassis control panel: a reset button and a power on/off switch. This chapter
explains the meanings of all LED indicators and the appropriate responses you
may need to take.
3-1
SC846 Chassis Manual
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.
Reset: The reset button is used to reboot the system.
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.
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.
Overheat/Fan Fail: When this LED flashes, it indicates a fan failure. When continuously 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 present 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.

activity when flashing.
Power: Indicates power is being supplied to the system's power supply units. This
LED should normally be illuminated when the system is operating.
!
Power Failure: When this LED flashes, it indicates a failure in the power supply.
3-3
SC846 Chassis Manual
3-4 Drive Carrier LEDs
Your chassis uses SAS/SATA.
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 SAS/SATA drive carrier) indicates drive activity.
A connection to the SAS/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.

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.
Redundant power supplies are hot-swappable, and can be changed without powering down the system. New units can be ordered directly from Supermicro (see
contact information in the Preface).

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 Precautions 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. 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.
5-1
SC846 Chassis Manual
!
Warnings and Precautions!
!
•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 simultaneously may cause the rack to become unstable.
General Server Precautions
•Review the electrical and general safety precautions that came with the components 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 touching them.
5-2
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 temperature 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 temperature (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 connections 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 components.
D-1 ESD Safety Guidelines
Electriostatic Discharge (ESD) can damage electronic components. To prevent damage 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 motherboard to prevent damage to the system due to power shortage.

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.

SC846 Chassis Manual
D-11 Supported Cascading Configurations
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.
