1-1 Safety Information
Electric Static Discharge (ESD) can damage electronic components.
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.\
Static-Sensitive Devices
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing the board from the antistatic
bag.
• Handle the board 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 motherboard 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 motherboard.
• Use only the correct type of onboard CMOS battery as specified by the manu-
facturer. Do not install the onboard battery upside down to avoid possible explo-
sion.
An important note to the user
All images and graphics shown in this manual were based upon the latest chas-
sis Revision available at the time of publishing. The chassis you’ve received may
or may not look exactly the same as the ones shown in this manual.

1. Turn off all peripheral devices connected to the SC742.
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 compo-
nents/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.
Using the Chassis Handles properly:
The chassos handles are for sliding the chassis in and out of the
racks only. Do not carry the chassis by the handles.
