Back in the day, waaaay back say around 1995, cold plugging was more
the norm. This was back when most everything ran on 10base2 and hubs
were a shared collision domain. Many 10base2 cards would do some
freaky things every once in a while, like pump +5 volts down the wire
Today I can't imagine why one would go with the cold plugging outside
of PoE, which you mentioned, or for high security networks.
