Can anyone think of a reason why a company would go through 3 switches in 3 months? 1 Netgear and 2 D-Link switches have burned out and they can't figure out why. I've never been to the place, but a CG I know does work for them and is baffled by these incidents. I told him to remove all unnecessary cabling from the switches and I will come out to test the working cables. In the meantime, I'm looking for any insight or anyone who has experienced this issue. TIA!

Do they have DC adapters? If not, i would check the your power source. Also, its not unreasonable to assume a bad nic card causing these problems, which will be a royal pain to determine; especially if you have a ton of nodes connected to the switch.

Does it kill all the ports on the switch? a bad NIC might be it. It could be bad power too. Do they have a UPS on the switch?
