Installing the Hardware
4. Caution should be taken for any cable connected to any outdoor device, not only on the device
grounding, but to ensure that any outdoor device cables that could carry surge currents, do not pass
those surge currents to upstream Ethernet switches.
Caution - Category 5e, Category 6, and Category 6a cables can store large amounts of static
electricity due to the dielectric properties of their construction materials in addition, this build up
of electricity could lead to a Cable Discharge Event (CDE). A CDE can occur due to the differential in
charges on the cable and the equipment it's being connected to. It is recommended that installers
momentarily ground all copper Ethernet cables (especially in new cable runs) to a suitable and safe
earth ground before connecting them to the port.
