Chapter 2: System Safety
Chapter 2
System Safety
2-1Overview
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, 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 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 ventilated. Avoid areas where heat,
electrical noise and electromagnetic fields are generated.
You will also need to place the chassis near at least one grounded power outlet.
When configured, the SC118G chassis includes one primary and in R-model chassis, one primary and one redundant power supply.
2-3 Preparing for Setup
The SC118G chassis includes a set of rail assemblies, including mounting brackets
and mounting screws you will need to install the system into the rack. Please read
this manual in its entirety before beginning the installation procedure.
2-4 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SC118G 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.
2-1
SC118G Chassis Manual
•Power should always be disconnected from the system when removing or install-
ing main system components, such as the serverboard and memory modules
(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 one grounded electrical outlet on standard chassis, two grounded
outlets with rudundant power supply R-model chassis.
•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. (CR2032) 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.
2-5 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.
2-2
Chapter 2: System Safety
•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.
•Handle the backplane 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.
2-3
SC118G Chassis Manual
•For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and
the serverboard.

5-7 System Fans
Figure 5-15: System Fan
Eight heavy-duty fans provide cooling for the chassis. These fans circulate air
through the chassis as a means of lowering the chassis' internal temperature.
The chassis includes counter-rotating fans. Each fan unit is actually made up of two
fans joined back-to-back, which rotate in opposite directions. This counter-rotating
action generates exceptional airflow and works to dampen vibration levels.
Fan Numbering in the BIOS
In the unlikely event of a fan failure, the failed system fan can be identified through
the BIOS, by utilizing the fan numbering system shown below. These numbers are
also imprinted on the floor of the chassis.

5-8 Power Supply
The SC118G chassis includes either one or two 1400 Watt power supplies. This
power supply is auto-switching capable. The power supply automatically sense and
operates at a 100v to 240v input voltage.
Power Supply Replacement
If the power supply unit fails, the system will shut down and you will need to replace
the unit. Replacement units can be ordered directly from Supermicro (see contact
information in the Preface). If there is only one power supply unit in the SC118G
chassis, power must be completely removed from the server before removing and
replacing the power supply unit. "R" model chassis with redundant power supplies
are hot-swappable and the power supply may be replaced without powering down
the server.

Chapter 6
Rack Installation
6-1Overview
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.
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 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.
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 (twenty-five inches).
•Leave approximately thirty 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).

Warnings and Precautions!
!
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-swapable hard drives and power supply modules 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.
6-2
Chapter 6: Rack Installation
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.).

SC118G Chassis Manual
6-4 Rack Mounting Instructions
This section provides information on installing the SC118G chassis into a rack unit
with the quick-release 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 32.5" deep.
Identifying the Sections of the Rack Rails
The chassis package includes two quick-release rail assemblies in the rack mounting
kit. Each assembly consists of two primary sections: an inner fixed chassis rail and
inner rail extention that secure directly to the chassis, and an outer rail assembly
that secures directly to the rack itself.

6-5 Installing the Server into a Telco Rack
To install the chassis into a Telco (post) type rack, use two L-shaped brackets (Optional with the MCP-290-00016-0N) on either side of the chassis (four total). First,
determine how far follow the chassis will extend out the front of the rack. Larger
chassis should be positioned to balance the weight between front and back. If a
bezel is included on your chassis, remove it. Then attach the two front brackets to
each side of the chassis, then the two rear brackets positioned with just enough
space to accommodate the width of the Telco rack. Finish by sliding the chassis
into the rack and tightening the brackets to the rack.
