Chapter 2 Preparing for Installation Electrostatic Discharge If you will be using your switch as a PoE source, the following warning applies: Warning Voltages that present a shock hazard can exist on inline power circuits if interconnections are made by using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods unless the exposed metal parts are in a restricted access location and users and service people who are authorized to access the loc

Chapter 2 Preparing for Installation Electrostatic Discharge Sometimes, voltage is discharged to some of the pins of the connector and not others, or to some pins on the connector before others. This is known as a differential discharge event, which can damage the networking equipment being connected. You can take the following measures to prevent ESD cable damage: • Ground the cable before connecting the networking equipment. You can create a grounding cable using an RJ-45 patch cable by d
