4.2 Working with Electrostatic Discharge (ESD) Sensitive Parts
When holding or exchanging ESD-sensitive parts, use the ESD kit, IBM part
6428316 or similar.
Read the instructions inside the top cover of the
carrying case.
Note:
The ESD kit must be used correctly during maintenance procedures to
maintain system availability.
All 3514 logic cards and disk drives are sensitive to electrostatic
discharge (ESD).
To prevent damage to these ESD-sensitive parts, follow
these instructions:
Before exchanging any part, control the electrical power to the part
as instructed in the procedure you are using.
Keep the ESD-sensitive part in its original shipping container until
you install the part in the machine.
When holding the ESD-sensitive part, 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 part, discharge any static
electricity in your body by touching the metal frame of the machine.
If possible, keep one hand on the frame when you are installing or
exchanging a ESD-sensitive part.
Hold the ESD-sensitive part by the edge or connector shroud cover.
not touch any connector or test point pins.
field-replaceable module, use the correct tool.
Return the part to its special container when it is not being used.
Do not place the ESD-sensitive part on the machine cover or on a metal
table.
Machine covers and metal tables are electrical grounds.
complete a discharge path from the ESD-sensitive part through your
body to ground, increasing the risk of damage to the card.
metal objects can be discharge paths without being grounded.
Prevent ESD-sensitive parts from being accidentally touched by other
persons.
Reinstall machine covers when you are not working on the
machine.
Do not place unprotected ESD-sensitive parts on a table.
Be careful when working with ESD-sensitive parts during cold weather
heating.
Cold weather heating causes low humidity and increases the
risk of static electricity.
