I checked the poles and the only ground is coming from the electrical sub panel. Which the goes uo to the lamp itself which housing is metal and is bolted on the metal post. So it is grounded to an extent but it does not have its own ground rod to earth ground next to the pole. Sorry im not an electrician, dont know how to properly ground a post. My data cables are not shileded and do not have lightning or surge protectors on them.
Also not sure what you meant about a protected enteance in the building. Protected how?
