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.

For more complete information on electrostatic discharge safety

precautions, refer to Bellcore
