When holding or installing electrostatic discharge-sensitive (ESD)
parts, use the ESD handling kit (IBM® part 6428316) or similar. Read the instructions
inside the top cover of the carrying case.
All system logic cards are sensitive to electrostatic discharge. To prevent
damage to ESD-sensitive logic cards, follow these instructions:
- Switch off power to the system or device before removing logic cards.
- Keep the ESD-sensitive card in the original shipping container until you
install the card in the machine.
- When holding logic cards, move your body as little as possible to prevent
an increase of static electricity from clothing fibers, carpet fibers, and
furniture.
- Just before touching the ESD-sensitive card, discharge any static electricity
in your body by touching the metal frame or cover of the machine. If possible,
keep one hand on the frame when, for example, you are installing or removing
a logic card.
- Hold the ESD-sensitive card by the edge or connector shroud cover. Do
not touch the pins. If you are removing a field-replaceable module, use the
correct tool.
- Return the card to the special container when it is not being used. Do
not place the ESD-sensitive card on the machine cover or on a metal table.
Machine covers and metal tables are electrical grounds. They make a discharge
path from the ESD-sensitive card through your body to ground, increasing the
risk of damage to the card. Large metal objects can be discharge paths without
being grounded.
- Prevent ESD-sensitive cards from being touched accidentally by other persons.
Reinstall machine covers when you are not working on the machine. Do not place
unprotected ESD-sensitive cards on a table.
- Be careful when working with ESD-sensitive cards during cold weather heating.
Cold weather heating causes low humidity and increases the risk of static
electricity.
