How to get back online after a power outage It’s possible that after electrical power is restored, you may still be without FiOS TV service. Sometimes resetting your Battery Backup Unit (BBU) is needed.

To reset your Battery Backup Unit:

1. Unplug the electrical power cord of your BBU from the wall outlet.
   
   
2. Wait one minute and then plug the cord back into the wall and see if the Optical Network Terminal (ONT) resets itself.
   
   If the ONT resets itself then your FiOS TV service should come back online. If it doesn't you can try to reconnect the battery.

To reconnect the battery in your BBU:

1. Unplug the electrical power cord of your BBU from the wall outlet.
   
   
2. Open the battery cabinet on the BBU (you may need a screwdriver to do this).
   
   
3. Disconnect the batter leads and wait 10 seconds. Reconnect the battery leads.
   
   
4. Put the battery cabinet back on and then plug the power cord back into the wall and see if the ONT resets itself.
   
   If the ONT resets itself then your FiOS TV service should come back online.
