[LUNI] Networking question -SOLVED ( I think )

[Mike Scott]

I quit buying Linksys switches as they were too quirky.
Sometimes plugging and unplugging a cable while powered would knock out
the port and the only way to get it back was to power cycle the switch.

I had this problem over the weekend with my only remaining Linksys
switch (will soon be relegated to the junk box as I lost half a day on
it before remembering the problem).  I had connected a 10/100/1000 BT
port on a server to it which it couldn't handle it, even though other
100M switches worked and the card was happy to run at 100M.  After 
switching to the 10/100 port, it still didn't work.  Powering down the
server and plugging into another port on the switch "fixed" the issue.

I'm still scratching my head as to why this is but atleast I have it working. Here's what I do know:
