connected the
BNC on the back of a VT220 to a thinwire ethernet
network.
We had a secretary do that once on an early Novel network, didn't
bring it down, just made it VERY SLOW. (The only thing we could
figure was that it allowed data during the re-trace(?).
When I got my first real job, being an IT monkey at Saxon Publishers, I
didn't know a thing about computer networks. I was expected to learn on
the job. One morning, I decided to change my cube's ethernet port from 10
Mbps to 100 Mbps. I located the corresponding cable in The Closet,
unplugged it from a 10 Mbps hub, plugged it into a 100 Mbps hub, and left
for class.
The problem was that I had plugged into port 16, which was shared with the
hub's uplink port. The hub dutifully provided service to my computer at
port 16 and forgot about the uplink, thus separating itself (and all the
Very Important Things connected to it) from the rest of the company
network. Business stopped, for 2.5 hours, until I returned gave my
frantic co-wokers the clue they needed.
I was not fired.
