Cam plus Base station Off line after firmware update

Cam plus Base station went offline after latest firmware update. All cameras are now offline. Tried unplugging base station, resetting base station, another Ethernet cable but still in blue flashing light no connection status. Not sure what else to try.

Ok, I fixed it. Had to hold the reset button down at least 30 seconds while it was flashing blue and then I had to add back in my cameras as new.
