Use these on ethernet. They ground all 8 pins, clamps voltage at 60v,
and provides bidirectional protection.. Never had one fail in 7
months. I live in the state of Michigan. 2nd worse for lightning. It
something protects here, it should protect anywhere else. http://www.demarctech.com/products/reliawave-poe/dt-poe-sp01.html Jeff Mabry wrote: You might try running a continuity test with your voltage meter.

Is there an easy/cheap way to test of the grounds are connected underground?-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of JohnnyO Sent: Tuesday, August 02, 2005 5:06 PM To: WISPA General List Subject: Re: [WISPA] Grounding questions/help Unless all of your grounds are bonded together - You stand the risk of causing your own nightmares due to the difference in potential across the 2 different grounding systems. Make sure everything is bonded together as 1 single grounding system.

Last night it took a hit, although it appears it came through the electrical and not the tower, but I'm not sure, the UPS was off, I reset it and it came back online --- but the POE injector did NOT, it was completely shot. Replaced the POE unit and the wireless gear came online, but started rebooting after about 15minutes (although it didn't this before, I just changed the POE from a 12v to 15v) tried a 24v POE, and the radio was still rebooting... Called the tower climber.. Anyways I looked over the ground and the tower appears to 3 ground rod off each tower leg and then the building has a separate ground rod - (unless its connected underground) Any thoughts?
