Hi, I have an observation that I would I want to clarify if it's normal or not.

On the HG630b, the LAN ports flash once a second and send out 512 bytes to the LAN.

I'm not sure why. Does it do this on other units people have or do I have a faulty onboard switch?

It seems to function perfectly fine. Except all the LAN ports flash exactly every second. I've disconnected everything and just hung a switch of the ports and they still flash every second.

I'm guessing the Spark firmware is polling the ports every second for some reason.
