Lost power this weekend (it was connected to an APC UPS) and after reboot the SB8200 steady blinks (all 4 LEDs and the Ethernet ports). There doesn't seem to be any decernabIe pattern. I also can't get DHCP directly connected to a computer or communicate with a static IP. Did the 10 sec hold several times on the reset button to do a factory reset. Behavior continues and is persistent regardless of what's attached to the modem. Device is still under warranty per this site.

If all the LED lights on the front panel of the SB8200 are flashing, first try connecting the modem to a different power outlet. If the issue persists, try using an alternate power cord.
Next, perform a factory reset by holding the reset button for 20 seconds.
If all the LED lights continue to blink after these steps, please reach out to our support team for further assistance by visiting www.arris.com/consumersupport.

Tried it for 20s this time and the lights just strobe, although they did go off after about 10s. I’ll have to call for support, my serial number doesn’t show up in the warranty checker...
