Chapter 1-Safety Information and Technical
Specifications
1-1 Electrical Safety Guidelines
Warning: To avoid electrical shock, check the power
cords as follows:
Checking the Power Cords
zUse the exact type of power cords as required.
zBe sure to use power cord(s) that came with safety certifications.
zThe power cord(s) must be compliant with the AC voltage requirements in your
region.
zThe power cord plug cap must have an electrical current rating that is at least
125% of the electrical current rating of this product.
zThe power cord plug cap that plugs into the AC receptacle on the power
supply must be an IEC 320, sheet C13, type female connector.
zBe sure to disconnect the power supply before accessing the SC743 or its
components.
zPlug the Power cord(s) into a socket that is properly grounded before
turning on the power.
Warning: Follow the guidelines below to avoid possible
damage to the system or injury to yourself:
General Electrical Safety Guidelines
zBe aware of the locations of the power switches on the chassis and in the
room, so you can disconnect the power supply if an accident occurs.
zTake extra precautionary measures when working with high voltage
components. It is not recommended to work alone.
zBefore removing or installing main system components, be sure to
disconnect the power first. Turn off the system before you disconnect
the power supply.
Use only one hand when working with powered-on electrical equipment to
avoid possible electrical shock.

Chapter 1: Safety Information and Technical Specifications
Use rubber mats specifically designed as electrical insulators when working
with computer systems.
The power supply or power cord must include a grounding plug and must
be plugged into grounded outlets.
Motherboard Battery: CAUTION -Make sure not to install the onboard battery
upside down to avoid possible explosion. Make sure that the positive side
is facing up on the motherboard. 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.
CD-ROM Laser: CAUTION - Do not open the enclosures of power supplies
or CD ROM to avoid injury.
1-2 General Safety Guidelines
Warning!! Follow the guidelines below to avoid
possible damage to the system or injury to yourself:
Keep the area around the SC743 clean and free of clutter.
To avoid injuries to your back, be sure to use your leg muscles, keep your
back straight, and bend your knees, when lifting the system.
Avoid wearing loose clothing to preventing it from coming into contact with
electrical circuits or being pulled into a cooling fan.
The handles are for sliding the chassis in and out of the
racks only. Do not carry the chassis by the handles.
After removing the components or chassis covers from the system, place
them on a table for safeguard.

1-3 ESD Safety Guidelines
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 the board from the 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.
Touch a grounded metal object before removing the board from the antistatic
bag.
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 motherboard 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
fasteners and the motherboard.
Electric Static Discharge (ESD) can damage electronic com-
ponents. To prevent damage to your system board, it is
important to handle it very carefully. The following measures are
generally sufficient to protect your equipment from ESD.
1-4 Operation Safety Guidelines
Warning: For proper cooling, make sure to install all
chassis covers before turning on the system. If this rule is
not strictly followed, warranty may become void. Do not open
the casing of a power supply. Power supplies can only be
accessed and serviced by a qualified technician of the manufacturer.

Chapter 1: Safety Information and Technical Specifications
To avoid personal injury and property damage, please carefully
follow all the safety steps listed below:
Before accessing the chassis:
1. Turn off all peripheral devices connected to the SC743.
2. Press the power button to power off the system.
3. Unplug all power cords from the system or the wall outlets.
4. Disconnect all the cables and label the cables for easy identification.
5. Use a grounded wrist strap designed to prevent static discharge when
handling components.
Removing the chassis covers:
After completing the above steps, you can remove the covers and install
components/peripheral devices into the chassis as described in Chapter 2.
1. Unlock and remove the screws and fasteners to remove the cover or
components.
2. Save all the screws and fasteners for later use. (If necessary, label these
screws or fasteners for easy identification.)
3. Follow the instruction given in Chapter 2 to remove the chassis covers.
Reinstalling the chassis covers:
To maintain proper system cooling and airflow, do not operate the system
without installing all chassis covers back to the chassis. To reinstall the chassis
covers, please follow the steps listed below:
1. Make sure that all components and devices are securely fastened
on the chassis and there are no loose parts/screws inside the chassis.
2. Make sure that all cables are properly connected to the connectors and ports.
3. Use the original screws or fasteners to install the covers to the chassis.
4. Be sure to lock to the chassis or the system to prevent unauthorized access.
5. For proper cooling, enclose the chassis with covers before operating the
system.

SC743 Chassis User’s Guide
Before installing the chassis into a rack:
1. Make sure that the rack is securely anchored onto an unmovable surface or
structure before installing the chassis into the rack.
2. Unplug the power cord(s) of the rack before installing the chassis into the
rack.
3. Make sure that the system is adequately supported. Make sure that all the
components are securely fastened to the chassis to prevent components
falling off from the chassis.
4. Be sure to install an AC Power Disconnect for the entire rack assembly and
this Power Disconnect must be clearly marked.
5. The rack assembly shall be properly grounded to avoid electrical shock.
6. The rack assembly must provide sufficient airflow to the chassis for proper
cooling.

(*Note: This driver is not necessary for other Operating Systems. If
you have two SCA backplanes, you will need to install the driver
twice.)
The driver is located on the Super Micro motherboard driver CD or is
available for download from our FTP site: ftp://ftp.supermicro.com/driver/

Follow the procedure below to install this driver to your system.
Installing the driver:
1) Right click on “My Computer” and choose “Property”.
2) Select “Hardware” tab and click on “Device Manager”.
3) Open “Other Devices” or wherever “GEM318” is on.
4) Right click on this device and choose “Property”.
5) Click on “Driver” tab and choose “Update Driver”.
6) Click “Next” 2 times, uncheck both “Floppy disk drives” and “CD-ROM
drives”. Then, select the item- “Specify a location,” and choose
“Next”.
7) Click on “Browse” and choose D drive or wherever Supermicro Setup
CD is in.
8) Choose “Qlogic” folder and click on “Open”.
9) System will automatically detect GEM318 and install the drive from this
point on.
or,
1) Right click the "My Computer" icon on your desktop and choose
Properties.
2) Click on the Hardware tab and click on "Device Manager" to bring up
the list of system devices.
3) You may see one or two yellow question marks (?) that read QLogic
GEM354 or GEM318 SCSI Processor Device. Right click on these, and
choose to uninstall. If two such question marks are present, uninstall
both.
4) Click on Action tab and choose "Scan for Hardware Changes". The
Hardware Wizard program should start up. Click "Next".
5) At the first prompt, choose “Display a list of known device drivers for
the device so that I can choose a specific driver” and click "Next".
6) Choose “Other Devices” and click Next.
7) Choose “Have Disk”, and specify your floppy drive location in the
options box. Then, click "Next".
