Safety Precautions
Be sure to follow all safety precautions when you replace components in
the system. To avoid electric shocks, burns, or equipment damage, read
and follow these warnings:
WARNING:
When the system is on, never insert a metal object, such as a
screwdriver or a finger with jewelry, into open module slots.
WARNING:
When the system is on, do not touch any connections inside
the chassis with your hands or fingers.
ESD Safety
Information
Electrostatic discharge (ESD) can damage components on the module.
ESD, which occurs when the module is improperly handled, can cause
complete or intermittent failures. To prevent ESD-related damage:
■
Always wear an ESD wrist strap connected to proper ground. Ensure
that the wrist strap makes good skin contact.
■
Keep the module in its antistatic shielded bag until you are ready to
install it.
■
Always handle the module by its edges.
■
Do not touch the components, pins, leads, or solder connections.
