THat would do suprisignly little damage I think. Ethernet conencotrs are
isolated from the rest of the machine (the traceiver chip is on the
conencotr side of the isolation barrier), so applyging mains to the BNC
connector (or indeed the 8p8c [1] of twisted-pair ethernet) will kil lthe
transciver chip, possibly the isolation transformern and DC-DC converter,
but will dont get much further.
On some systems Ethernet is also fused (I once blew the Ethernet fuse on
a SPARCstation 1(+)... can't remember how).

At least one. I call it my "serial killer".
Supplies mains voltage to every alternate pin on a DB25.
Sounds suspiciously like the BOFH's EtherKiller, the mains cord with a
BNC plug on the other end.>
[1] It's not RJ45 damnit!
Applying mains to na RS23 2connecotr could end up blowing out chips all
over the machine....
And while both D-seires nad BNC connectors are rated for votlages bove
mains, I do have a problem with having one side of the mains connected ot
the metal shell of a BNC plug.
