ESD Precautions
Before you begin any of the procedures, consider the following precautions and preventive measures.
Preventing ESD
To prevent electrostatic discharge (ESD) from damaging the system, be aware of the precautions to
consider when setting up the system or handling parts. A discharge of static electricity from a finger
or other conductor may damage system boards or other static-sensitive devices. This type of damage
may reduce the life expectancy of the device.
