PoE cable run limits by length and cable category

Whether a given run length is within the ANSI/TIA-568 Ethernet channel limit, and what to do about a run that is longer than the standard allows.

The 100 metre channel limit is a signal timing constraint, not a power one, and it rarely fails cleanly when exceeded.
