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. These instructions assume 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, file a damage claim with the carrier
who delivered your system.
Decide on a suitable location for the rack unit that will hold the chassis. It should
be situated in a clean, dust-free area that is well ventilated. Avoid areas where
heat, electrical noise and electromagnetic fi elds are generated.
You will also need it placed near at least two grounded power outlets. The SC836
chassis includes two redundant power supplies which require two grounded out-
lets.
2-3 Preparing for Setup
The SC836 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 SC836 from damage:
lBe 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 electri-
2-1

2-2
cal outlet. If an electrical accident occurs, you can then quickly remove
power from the system.
lDo not work alone when working with high voltage components.
lPower should always be disconnected from the system when removing or
installing main system components, such as the serverboard, memory mod-
ules and the DVD-ROM and floppy drives (not necessary for hot swappable
drives). When disconnecting power, you should fi rst power down the
system with the operating system and then unplug the power cords from all
the power supply modules in the system.
lWhen 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.
lUse 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.
lDo 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.
lThe power supply power cord must include a grounding plug and must be
plugged into grounded electrical outlets.
lServerboard 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.
lDVD-ROM Laser: CAUTION - this server may have come equipped with a
DVD-ROM drive. To prevent direct exposure to the laser beam and hazard-
ous radiation exposure, do not open the enclosure or use the unit in any
unconventional way.
2-5 General Safety Precautions
lKeep the area around the chassis clean and free of clutter.
Page 17
2-3
Chapter 2: System Safety
lPlace the chassis top cover and any system components that have been
removed away from the system or on a table so that they won’t accidentally
be stepped on.
lWhile 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.
lRemove 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.
lAfter 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:
lDo 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.
lUse a grounded wrist strap designed to prevent static discharge.
lKeep all components and printed circuit boards (PCBs) in their antistatic
bags until ready for use.
lTouch a grounded metal object before removing any board from its anti-
static bag.
lDo not let components or PCBs come into contact with your clothing, which
may retain a charge even if you are wearing a wrist strap.
lHandle a board by its edges only; do not touch its components, peripheral
chips, memory modules or contacts.
Page 18
SC836 Chassis Manual
lWhen handling chips or modules, avoid touching their pins.
lPut the serverboard and peripherals back into their antistatic bags when
not in use.
lFor grounding purposes, make sure your computer chassis provides excel-
lent conductivity between the power supply, the case, the mounting fasten-
ers and the serverboard.

4-2 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.
l Reset: The reset button is used to reboot the system.
l Power: The main power switch is used to apply or remove power from
the power supply to the server system. Turning off system power with this but-
ton removes the main power but keeps standby power supplied to the system.
Therefore, you must unplug system before servicing.
4-3 Control Panel LEDs
The control panel located on the front of the SC836 chassis has 6 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.
lPower Failure: When this LED flashes, it indicates a power failure in the
power supply.
Page 23
4-3
Chapter 4: System Interface
l Power: Indicates power is being supplied to the system's power supply
units. This LED should normally be illuminated when the system is operating.
lOverheat/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 tem-
perature 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.
l NIC2: Indicates network activity on LAN2 when flashing.
l NIC1: Indicates network activity on LAN1 when flashing.
l HDD: Indicates IDE channel activity. SAS/SATA drive, SCSI drive, and/or
DVD-ROM drive activity when flashing.

Chapter 5: Chassis Setup
5-5 Installation Step 3: Installing the Motherboard
Permanent and Optional Standoffs
Standoffs prevent short circuits by securing space between the motherboard and
the chassis surface. The SC836 chassis includes permanent standoffs in locations
used by most motherboards. These standoffs accept the rounded Phillips head
screws included in the SC836 accessories packaging.
Some motherboard 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 secure a hexagonal post by screwing
it into the necessary spot.
Standoffs Labeling
Standoff locations are labeled on the bottom of the SC836 chassis with the letters:
P, D, and A.
P = Most compatible motherboards have a processor or CPU located here. If
necessary, place standoffs here for the CPU's heatsink.
D = Place optional standoffs here if your motherboard requires additional posts to
hold the unit in place.
A = A number of older motherboards have processors or CPUs located in areas
designated "A". Place standoffs here for the CPU's heatsink.
To install the motherboard:
1. Review the documentation that came with your motherboard. Become familiar
with component placement, requirements, and precautions.
2. Confi rm that the power supply is disconnected and lay the chassis on a flat
surface.
3. Open the chassis cover.

Dual Host Bus Adapter
In a Dual Host Bus Configuration, the
backplane connects to two Host Bus
Adapters (HBA).
Dual Host Bus Adapter Failover
If the Expander or data path in Port A
fails, the system will automatically fail
over to Port B. This maintains a full
connection to all drives.
6-4 Cascading Backplanes
The SC 836 chassis supports cascading when coupled with an 836EL series
backplane or other Supermicro backplane with Expander capabilities.
Power Control Card
In a cascaded configuration, backplanes can be linked to create "Just a Bunch of
Drives" or JBOD. The primary server requires a Host Bus Adapter (or motherboard).
The other servers require a Control Card or Power Card.

Chapter 7
Rack Installation
7-1 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.
7-2 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 fi elds 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.
7-3 Preparing for Setup
The box your chassis was shipped in includes one set of rail assemblies (two in-
ner and 2 outer) 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.
- This product is for installation only in a Restricted Access Location (dedicated
equipment rooms, service closets and the like).
7-1
Page 48
SC836 Chassis Manual
7-2
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 compo-
nents 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 fi 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.
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating tem-
perature 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.
Warnings and Precautions!
Page 49
7-3
Chapter 7: Rack Installation
Reduced Airfl ow
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.).

2. Attach a short bracket to the front side of the right outer rail and a long bracket
to the rear side of the right outer rail.
3. Adjust both the short and long brackets to the proper distance so that the rail
can fit snugly into the rack.
4. Secure the short bracket to the front side of the outer rail with two M4 screws
and the long bracket to the rear side of the outer rail with three M4 screws.
5. Repeat these steps for the left outer rail.

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.
1-2 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.

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 identifi 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.

Cascading allows the system to access data at a faster rate by allowing several
backplanes to share resources to reduce latency time.
The fi rst backplane in a cascaded system requires a motherboard and HBA. Other
servers require a power control card, not a motherboard and HBA. For more infor-
mation, see the SC836 Chassis Manual.

Other Considerations:
l Cascading supports up to 122 hard drives
