Connecting the Switches which offers 6Kv surge protections to Earth ground

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper

operation, All the Switches must be adequately grounded before power is connected. To ground the

switch, you must connect a grounding cable to earth ground and then attach it to the rack grounding

points.

Systems that do not use electrical grounding components can experience either complete system

failures or intermittent problems that are hard to diagnose. The surges and spikes can cause

permanent damage, like how a nearby lightning strike can burn electronics and wires. They may also

cause small latent failures that erode equipment and cause permanent damage over time.

Please see below images about grounding connections from switch. If without grounding cable then

the lighting or surge will damage the chip or protection components.

illustrates how a grounding cable connect to the PoE Switches.
