Electrostatic Discharge (ESD) Precautions Electrostatic charges can damage the integrated circuits on printed circuit boards. To prevent such damage from occurring, observe the following precautions when unpacking and installing the board. D Stand on a static-free mat. D Wear a static strap to ensure that any accumulated electrostatic charge dis- charges from your body to ground. D Connect all equipment together, including the static-free mat, static straps, routing nodes, and peripheral units. D Keep uninstalled printed circuit boards in their protective antistatic bags. D Handle printed circuit boards by their edges, once you have removed them from their protective antistatic bags. Laser Safety Statement (For U.S.A. Only) (For workstations that have a CD-ROM drive installed.) The CD-ROM mass-storage system is certified as a Class-1 laser product under the U.S. Department of Health and Human services (DHHS) Radiation Performance Standard according to the Radiation Control for Health and Safety Act of 1968. This means that the mass-storage system does not produce hazardous laser radiation. Because laser light emitted inside the mass-storage system is completely confined within protective housings and external covers, the laser beam cannot escape from the machine during any phase of user operation. vii

Electrostatic Discharge (ESD) Precautions
Electrostatic charges can damage the integrated circuits on printed circuit boards. To
prevent such damage from occurring, observe the following precautions when un-
packing and installing the board.
D
Stand on a static–free mat.
D
Wear a static strap to ensure that any accumulated electrostatic charge dis-
charges from your body to ground.
D
Connect all equipment together, including the static–free mat, static straps,
routing nodes, and peripheral units.
D
Keep uninstalled printed circuit boards in their protective antistatic bags.
D
Handle printed circuit boards by their edges, once you have removed them
from their protective antistatic bags.
