Notes

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, 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 it placed near at least one grounded power outlet. When con-
figured, the SC745 chassis includes one power supply. "R" models (i.e. SC745S-
R650V Chassis) include a redundant power supply and require two grounded
outlets.
2-3 Preparing for Setup
The SC745 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.

SC745 Chassis Manual
2-2
2-4 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SC745 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 electri-
cal 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
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 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.

2-3
Chapter 2: System Safety
DVD-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
Keep the area around the chassis clean and free of clutter.
Place 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.
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.

SC745 Chassis Manual
2-4
Touch a grounded metal object before removing any board from its anti-
static 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 excel-
lent conductivity between the power supply, the case, the mounting fasten-
ers and the serverboard.

Chapter 3:
Chassis Components
3-1 Overview
This chapter describes the most common components included with your chassis.
Some components listed may not be included or compatible with your particular
chassis model. For more information, see the installation instructions detailed later
in this manual.
3-2 Components
Chassis
Chassis include three 5.25" peripheral drive bays and eight hard drive bays. For the

This chassis accepts three hot-swappable system cooling fans and one (sometimes
two) power supplies. SC745 models come in beige and black.
Backplane
Each SC745 chassis comes with a 4U backplane. Depending on your order, your
backplane will accept SAS/SATA or SCSI. For more information regarding compat-
ible backplanes, view the appendices found at the end of this manual. In addition,
visit our Web site for the latest information: http://www.supermicro.com.
Fans
The SC745 chassis accepts three system fans and two rear exhaust fans. System
fans for SC745 chassis are powered from the serverboard. These fans are 4U high
and are powered by 3-pin connectors.
