Fluke One Touch - High Voltage
Hello, I have a question that stemmed from troubleshooting a system on my network here at the school that I work for. The system was reporting 'a network cable is unplugged.'. The cable was clearly plugged in, so I ran and got my handy Fluke One Touch analyzer, and tested the patch cable. It tested fine. So I thought maybe there was a problem in the cat-6 between the outlet and our patch panel. When I tried to run the test on that, the Fluke device reported:
'Danger: High Voltage detected on RJ45 network, please reset device' [paraphrasing here].
I have used this same Fluke tester multiple times and had never come across this message. I tried all 4 jacks in the classroom, all of them said that. So I went across the hall to that particular teacher's office, and tried the jack in there. It worked fine. No trouble at all.
So I was wondering if anyone here has come across this message. I did not cable the building, nor have I been up in the ceiling, so I don't know the proximity of the cabling to the power lines. The building is only 2 years old, and the cabling was done by contractors as it was built, so I cannot imagine that they would have run the cable along side high voltage lines. Stranger things have happened though. He has another system plugged into one of the outlets that gave me this warning that is functioning on the network. Though I am wondering if the excess voltage may have damaged the card in the other machine, hence the network cable unplugged problem.
I haven't done too much to troubleshoot [ie plugging the machine into another outlet etc], I was mainly concerned with the high voltage message.
Thoughts??
Thanks for any help.
