Thank you for your assistance. It is greatly appreciated. We have called Lennar for support phone numbers, but they only have the number to contact Ruckus.
Response to your question:
1-On your switch while it's plugged into the outlet, do you see any lights on? (Amber or green) Please let us know which lights are on?
On the ICX7150-C12P it is plugged into a good power source and there are green lights on under the STAT, SYST and PWR.
We have two R510 units. The first one has four green lights on (no AIR light is on). On the other unit, has a solid green on PWR and a blinking green on CTL. Tried the reset on this unit - no change.
We are trying to determine is in one of the R510 units or the ICX7150-C12P switch.
Thanks again for your assistance!
