Static Electricity can damage or decrease the reliability of electrical and optical equipment. While
unpacking and handling electrical and optical equipment, wear a grounding wrist strap to dis-
charge the static buildup. The grounding wrist strap is designed to prevent equipment damage
caused by static electricity. Before unpacking and installing equipment or making system intercon-
nections, connect the grounding wrist strap.
