ESD prevention
To prevent the electronic components from being damaged by the electrostatic discharge (ESD), follow these guidelines:
Ground the switch correctly. For how to ground your switch, see "Installing the switch."
Always wear an ESD wrist strap when installing components, especially the electronic printed circuit boards.
Hold a PCB by its edges. Do not touch any electronic components or printed circuit.
Check the resistance of the ESD wrist strap for safety. The resistance reading should be in the range of 1 to 10 megohm (Mohm) between human body and the ground.
To attach the ESD wrist strap:
Wear the wrist strap on your wrist.
Lock the wrist strap tight around your wrist to keep good contact with the skin.
Insert the ESD wrist strap into the ESD socket on the switch chassis.
Make sure the ESD wrist strap is correctly grounded.
