Chapter 2
System Safety
2-1Overview
This chapter provides a quick setup 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. 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 fields 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 outlets.
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.
2-1
SC836 Chassis Manual
2-4 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SC836 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 (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.
2-2
Chapter 2: System Safety
•Handle used batteries carefully. Do not damage the battery in any way; a dam-
aged battery may release hazardous materials into the environment. Do not
discard a used battery in the garbage or a public landfill. 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 unconventional 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.
2-3
SC836 Chassis Manual
•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.
•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.

5-5 Installing the Motherboard
Permanent and Optional Standoffs
Standoffs prevent short circuits by creating 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 securing within the chassis. Optional standoffs are included to
these motherboards. To use an optional standoff, you must place it into the desired
position in the chassis and secure it with a screw.
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.
Motherboard Installation
Installing the Motherboard
1. Review the documentation that came with your motherboard. Become familiar
with component placement, requirements, and precautions.
2. Confirm that the power supply is disconnected and lay the chassis on a flat
surface.
3. Open the chassis cover.
5-5
SC836 Chassis Manual
4. Remove any packaging from the chassis. If the rear fans (set of two fans
nearest the I/O slots) or the air shroud are in place, remove them.
5. If required by your motherboard, install standoffs in any areas that do not
have a permanent standoff. To do this, place an optional hexagonal standoff
into the chassis and secure it with a screw. Compare the holes in the motherboard to those in the chassis and add or remove standoffs as needed.
6. Lay the motherboard in the chassis, aligning the permanent and optional
standoffs.
7. Secure the motherboard to the chassis using the rounded, Phillips head
screws. Do not exceed eight pounds of torque per square inch when tightening down the motherboard.
8. Secure the CPU(s) and heatsinks to the motherboard.

Explanation of Jumpers
Connector
Pins
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.

C-13Failover with RAID Cards and Multiple HBAs
The SAS-836EL backplane may be configured for failover with multiple HBAs using
either RAID controllers or HBAs to acheive failover protection.
RAID Controllers: If RAID controllers are used, then the failover is accomplished
through port failover on the same RAID card.
HBAs: If multiple HBAs are used to achieve failover protection and load balancing,
Linux MPIO software must be installed and correctly configured to perform
the load balancing and failover tasks.

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.

The activity LED headers, designated JP26
and JP47, are used to indicate the activity
status of each SAS drive. These activity LED
headers are used by the host controller for
the SATA drives that previously had no activity status output. If using a SAS drive, and
for most SATA drives, these activity headers
are not required.The Activity LED Header is
located on the front panel. For the Activity
LED Header to work properly, connect using a
10-pin LED cable.

The activity LED headers, designated JP26
and JP47, are used to indicate the activity
status of each SAS drive. These activity LED
headers are used by the host controller for
the SATA drives that previously had no activity status output. If using a SAS drive, and
for most SATA drives, these activity headers
are not required.The Activity LED Header is
located on the front panel. For the Activity
LED Header to work properly, connect using a
10-pin LED cable.

To avoid personal injury and property damage, carefully follow all the safety steps
listed below when accessing your system or handling the components.
F-1 ESD Safety Guidelines
Electrostatic 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 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.
F-1
SC836 Chassis Manual
F-2 General Safety Guidelines
•Always disconnect power cables before installing or removing any components
from the computer.
•Disconnect the power cable before installing or removing any cables from the
card.
•Make sure that the card is securely and properly installed on the motherboard
to prevent damage to the system due to power shortage.
F-3 An Important Note to Users
•All images and layouts shown in this user's guide are based upon the latest PCB

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.

Installing Hard Drives in the Rear Hard Drive Carriers
The 2.5" hard drives which are to be installed in the rear of the SC836B are
hot-swappable and may be installed without powering-down the server.
Note that only enterprise level hard drives are recommended for use in Supermicro
chassis.
Installing the Hard Drives in the Carrier
1. Remove the screws securing the dummy drive to the hard drive carrier and
remove the dummy drive from the carrier.
2. Insert a hard drive into the carrier with the PCB side facing down and the
connector end toward the rear of the carrier.
3. Allign the mounting holes in the drive with those in the carrier. Note that there
are holes in the carrier marked "SAS" or “SATA” to aid in correct installation.
4. Secure the drive to the carrier with four screws. Use the four M3 flat-head
screws included in the HDD bag of your accessory box. Note that the screws
used to secure the dummy drive to the tray cannot be reused to secure the
hard drive.
