While troubleshooting a connection issue on my home network, I noticed that there was a device connected to my 10/100/1,000 Mbps Ethernet switch that was connecting at less than 1,000 Mbps. It was the Insteon Hub model 2245-222 that I had installed a few months ago.
Was there something wrong with the connection that prevented it from connecting at a gigabit per second, or was the interface on the hub not gigabit capable? My gigabit switch only indicates if the connection is 10/100 or 1,000 Mbps. The hub’s manual didn’t say what the interface speed was. An Internet search seemed to indicate that the interface may only be capable of 10 Mbps, but I had to know for sure!
I dug a 10 Mbps hub and a 100 Mbps switch out of my box of antiquities and did some testing. The hub was able to connect at 10 or 100 Mbps, but not at 1,000 Mbps. Mystery solved!
For posterity, here is what the LEDs on the Insteon Hub model 2245-222 Ethernet interface mean:
|Left LED Blank||10 Mbps|
|Left LED Amber||100 Mbps|
|Right LED Blank||No Link|
|Right LED Green||Link|
I finished off the testing by printing my own labels for the hub!
