No, not talking about 2 different rules. My point was that if you have to do that anyway, then put the POE there and extend the link however they want past that. Fiber sounds like it would make the most sense.

Yeah, we're supposed to ground cables going from outside to in. Also the outdoor cable is only supposed to go so many feet into the building and then transition to an indoor cable. Here it's 50ft. This is supposedly a fire code thing, because outdoor cable doesn't have the same rules for smoke and flammability. This rule is commonly ignored, but it's a real thing.

Secondary ground rods are a no no here.

Seems like if you have to ground it anyway within 20 feet of entry, put the POE there and then they can have their extender wherever they want along the rest of the run.

Sometimes we get a win.

It might just work without any faffing around.

If it does manage to keep the radio powered i see it burning out the poe circuit. hes fighting me on putting the cambium PSU at the midspan point and using his own POE to power the extender. Ive been overruled about telling the customer no, so its happening, but I want to make sure my math is correct using https://www.rapidtables.com/calc/wire/voltage-drop-calculator.html 24guage, 30v, .5 amp, 400 feet shows 10v drop. but im not sure about the resistivity field this is a guy who runs constant latency monitoring and initiates tickets on every blip, so i see this radio move just becoming a nightmare with this midspan extender in play -- AF mailing list [email protected]<mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com ________________________________ Total Control Panel Login<https://portal.reflexion.net/login?domain=litewire.net> To: [email protected]<https://portal.reflexion.net/address-properties?aID=242260993&domain=litewire.net> From: [email protected]<mailto:[email protected]> You received this message because the domain afmug.com<http://afmug.com> is on your allow list. -- AF mailing list [email protected]<mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com ________________________________ Total Control Panel Login<https://portal.reflexion.net/login?domain=litewire.net> To: [email protected]<https://portal.reflexion.net/address-properties?aID=242260993&domain=litewire.net> From: [email protected]<mailto:[email protected]> You received this message because the domain afmug.com is on your allow list. -- AF mailing list [email protected]<mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com ________________________________ Total Control Panel Login<https://portal.reflexion.net/login?domain=litewire.net> To: [email protected]<https://portal.reflexion.net/address-properties?aID=242260993&domain=litewire.net> From: [email protected]<mailto:[email protected]> You received this message because the domain afmug.com is on your allow list. ________________________________ -- AF mailing list [email protected]<mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com ________________________________ Total Control Panel Login<https://portal.reflexion.net/login?domain=litewire.net> To: [email protected]<https://portal.reflexion.net/address-properties?aID=242260993&domain=litewire.net> From: [email protected]<mailto:[email protected]> You received this message because the domain afmug.com is on your allow list.
