Safety Precautions
Before getting started, please read the following important safety precautions.
1. Be sure to ground yourself to prevent static charge when installing any internal
components. Use a grounding wrist strap and place all electronic components in any
static-shielded devices. Most electronic components are sensitive to static electrical
charge.
2. Disconnect the power cord from the GOT321W-502-PCT/FR series prior to any
installation. Be sure both the system and all external devices are turned off. Sudden
surge of power could ruin sensitive components. Make sure the GOT321W-502-PCT/FR
Series is properly grounded.
3. Do not open the system’s back cover. If opening the cover for maintenance is a must,
only a trained technician is allowed to do so. Integrated circuits on computer boards are
sensitive to static electricity. To avoid damaging chips from electrostatic discharge,
observe the following precautions:
Before handling a board or integrated circuit, touch an unpainted portion of the
system unit chassis for a few seconds. This will help to discharge any static
electricity on human body.
When handling boards and components, wear a grounding wrist strap available
from most electronic component stores.

NOTE: Always turn off your computer and unplug the power cord from the power outlet
before clearing the CMOS values. After system restart, go to BIOS Setup to load
factory defaults (select Load Optimized Defaults) or manually configure the BIOS
settings.
