Recently undergoing a lounge renovation, the audio system was dismantled including the EtherRegen. I found with great difficulty to unplug the Ethernet cable, the jack had a distorted plastic case and wouldn't disconnect. Spent several minutes trying to dislodge, but eventually came out. The rj45 case felt brittle, most likely due to the heat.
The next rj45 goes in will have to cope with an ambient of 80C to avoid the same drama. I just wonder how the tiny connections hold up...
