Preventing electrostatic discharge To prevent damaging the system, be aware of the precautions you need to follow 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 staticsensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage: • Avoid hand contact by transporting and storing products in static-safe containers. • Keep electrostatic-sensitive parts in their containers until they arrive at staticfree workstations.
