Grounding a POE-powered device
If you let user touch grounded chassis of the screen, or step onto the metallic plate with bare feet, it may cause shock or at least unpleasant feelings if user will appear highly charged (e.g.

How to handle chassis ground on DC powered system without
Adding POE PD is pretty easy. I''m using the SI3404 without an isolation transformer because POE is automatically SELV so isolation isn''t required. Because the device is powered by 24V DC, earth

PoE+ grounding/isolation conundrum
It is best to connect the shielding to earth ground as it will present to lowest resistance path for unwanted energy (ESD etc) from reaching any circuitry inside the enclosure and might damage it.
