We lost power for hours on March 2nd, and after power was restored, the FIOS internet/voice never returned. Battery Backup showed drained battery (red blink on BBU), and steady green LED on 47V Power Supply (PSU).\, and ONT LEDs dark.
After I replaced the BBU battery, the internet/voice returned, but internet failed after about 5 minutes. Rinse and repeat. :-)
Internet goes out when "link" goes dark on the Ethernet port of the ONT (and corresponding Ethernet on Actiontek router also goes dark).
I determined that the 47V PSU is faulty and needs replacement (this, despite steady green on PSU). Battery Back Up shows orange/orange, indicating battery not charging.
I cannot get through the support to request service to replace the PSU. We spent hours on hold!!
Please help.
Thanks!
