On some systems Ethernet is also fused (I once blew
the Ethernet fuse on
a SPARCstation 1(+)... can't remember how).
That fuse (it's a resettable circuit breaker on some DEC machines)
protects the power to the transcier circuit. It's commonly present on
machiens with AUI connectors (DA15s for an external transceiver) so that
a short in the transceiver or drop cable doesn't do any damage.
Since it's on the machine side of the isolation barrier, I don't think
the eterhkiller would bbow it. I am not going to test that practically,
though.
