Cat5 cable, running through a buried conduit. Normally this has been<br>
working fine, but after yesterday's thunderstorm I found that the<br>
switch port on one end of this connection had been fried. (The rest<br>
of that switch was fine, as was the one on the other end of the link.)<br>
I've had one other switch completely fail after a storm, too.<br>
<br>
So, for any of you EEs out there: am I right in assuming that the long<br>
run of cable picked up a voltage spike during the storm? If so, is<br>
there any kind of isolation or lightning protection I can use on the<br>
inter-building link that won't cost more than simply replacing the<br>
switch every couple of years?<br>
