RE: CAT5 surge/lightning strike protection recommendations?

  • From: Wallace Keith
  • Date: Tue Sep 13 16:48:52 2005

I've had good luck with Oneac products, such as RJELP100. That being
said, it's probably not a good idea to connect switches and/or pc's  in
different buildings with  copper. I'd use fiber between buildings if at
all possible . Differences in ground potential between buildings
(especially during electrical storms) can not only wipe out a switch
port or nic card, but could be lethal to the poor soul with one hand on
a mouse and the other on some nearby grounded object...
Regards,
Keith

Subject: CAT5 surge/lightning strike protection recommendations?


I have a bunch of cat5 buried about 1 ft below the surface connecting
multiple buildings on a campus (short runs) and lightning strikes nearby
have caused surges along one or more of the cables and burnt out switch
ports. I would like to protect the switch ports -- there seem to be lots
of products on the market.

Anyone have recommendations (tested/practical is best :-)?

The APC Protectnet PNET1 and PRM24 seem quite nice and not too expensive
-- if they work....pros? cons?

Thanks,
Adi
