Sounds suspiciously like the BOFH's EtherKiller, the mains cord with a
BNC plug on the other end.>
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).
I know my DELQA cable kit has a fuse in it, but I think it's for the AUI-supplied
power instead of any signal lines.
Yep, that's what the onboard Ethernet fuse is for on earlier Sun systems.
