Where "several thousand Volts" is 1500V minimum according to IEEE 802.3.
Since more isolation costs more money, don't count on any normal product to
have more than 1500V isolation. In fact, given that it's all made as
cheaply as possible, I'm not sure you should really even count on 1500V.
What amazed me is that none of the NICs blew,
none of the machines failed
or died. Once the cabling was sorted, it was OK. Who knew that BNC Ethernet
ports could handle 100V or more flowing through them and mostly work?
They are galvanically isolated, good for several thousand Volts.
