Have run this to a 5G Modem device for MONTHS without issue. Finally the modem got tagged by some EMI during a nasty storm with lots of lightning. Took out the LAN port on the router and the network side of this device, but only on the device side. So it sacrificed itself at the switch to protect everything downline.
Swapped with a new unit / used a different LAN port and we're back in business. Only so much you can do with lightning!
We've been finding other uses for them, like retrofits for old TimeClocks that don't have PoE capability. Impressed with the reliability.
