Correct.  There is no LAN activity at all on the device.  The OS is not booting.  Red light on back just blinks and the only green light that is lit and blinking is on the NIC, but there is no traffic going over the wire.  I'm pretty sure the firmware went terribly wrong.  After clicking to flash the device, I walked away and when I came back I had page not found in the browser.

After repeated emails, still haven't heard back from Bitmain.

I did that, nothing happened

Unfortunately I upgraded the firmware and have gotten the same result.  System won't boot.  Red light blinks every second and green light on ethernet blinks in bursts.  Factory reset did nothing.  Neither did moving the cables..which was a long shot.  I think the firmware update bricked the unit.
