4.1 Anti-static Precautions

WARNING:
Failure to take ESD precautions during the installation of the WSB-G41A may result in permanent damage to the WSB-G41A and severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components, including the WSB-G41A. Dry climates are especially susceptible to ESD. It is therefore critical that whenever the WSB-G41A or any other electrical component is handled, the following anti-static precautions are strictly adhered to.
Wear an anti-static wristband: Wearing a simple an ti-static wristband can
WSB-G41A CPU Card
help to prevent ESD from damaging the board.
Self-grounding: Before handling the board, touch any grounded conducting
material. During the time the board is handled, frequently touch any conducting materials that are connected to the ground.
Use an anti-static pad: When configuring the WSB-G41A, place it on an
antic-static pad. This reduces the possibility of ESD damaging the WSB-G41A.
Only handle the edges of the PCB: When handling the PCB, hold the PCB
by the edges.

Before and during the installation please DO the following:
Read the user manual:
o The user manual provides a complete description of the WSB-G41A
installation instructions and configuration options.
Wear an electrostatic discharge cuff (ESD):
o Electronic components are easily damaged by ESD. Wearing an ESD cuff
removes ESD from the body and helps prevent ESD damage.
Place the WSB-G41A o n a n antistatic pad:
o When installing or configuring the motherboard, place it on an antistatic
pad. This helps to prevent potential ESD damage.
Turn all power to the WSB-G41A off:
o When working with the WSB-G41A, make sure that it is disconnected
from all power supplies and that no electricity is being fed into the system.
Before and during the installation of the WSB-G41A DO NOT:
Remove any of the stickers on the PCB board. These stickers are required for
warranty validation.
Use the product before verifying all the cables and power connectors are
properly connected.
