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 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 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.
