CAUTION
•
Install or remove modules from the shelf only when the power is off.
If you install a module in the shelf with the power on, the internal
circuitry may suffer damage and the product warranty will be void.
•
Remove and install circuit boards only in a static-safe environment
(use antistatic wrist straps, smocks, footwear, etc.).
•
Keep circuit boards in their antistatic bags when they are not in use.
•
Do not ship or store circuit boards near strong electrostatic, electromag-
netic, magnetic, or radioactive fields.
