Safety considerations
Before performing service procedures, review all the safety information.
Preventing electrostatic discharge
To prevent damaging the system, be aware of the precautions you must 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 static-sensitive 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 static-free workstations.
•
Place parts on a grounded surface before removing them from their containers.
•
Avoid touching pins, leads, or circuitry.
•
Always be properly grounded when touching a static-sensitive component or assembly.
