Internet Battery Backup (Reliability Plus Feature)

In this article, you’ll learn about GFiber’s Internet Battery Backup in general, including how it works, how to purchase it, and other helpful details.

How it Works

GFiber uses light rather than electrical impulses to deliver internet, making the fiber network itself highly reliable during power outages. However, your router and Fiber Jack still require electricity to function.

The Internet Battery Backup (a Reliability Plus feature) automatically kicks in during a power outage to provide up to 2 hours of full-bandwidth uptime with no internet slowdowns.¹

Important Note: The battery backup only powers your primary internet connection (router and Fiber Jack). It will not power your Mesh Extenders, meaning they will go offline unless you have a separate backup power source for them. It also may not function during widespread outages that affect centralized networking facilities.

Pricing & Eligibility

Internet Battery Backup is available only for specific residential plans and is restricted in buildings with five or more units.

Plan	Eligibility & Cost	How to Get It
Edge 8 Gig	Included at no additional cost (must opt-in)	Select during signup (new) or upgrade via account/phone (existing).

Installation Process

GFiber requires professional installation for this device.

New Customers: Schedule your installation appointment during service signup.
Existing Customers: After upgrading your plan and opting into the backup, you will be prompted to schedule a technician visit.
Multiple Units: If your Fiber Jack and router are in separate rooms, the technician may install two separate sets of battery backups.

Setup Verification (Testing the Backup)

Once installed, the device works automatically. However, you can verify it is running correctly using these steps:

Check Cables: Ensure the battery is connected to its power supply unit. You should have one power cable running from the wall to the power supply, and another cable with two connectors attached to your router and Fiber Jack.
Verify Power: Check that the lights on your router and Fiber Jack are on. (Note: There is a physical power button on the bottom of the Fiber Jack if it needs to be turned on manually).
Simulate an Outage: Unplug the AC wall outlet cable from the power supply module for a few seconds. The router and Fiber Jack should remain powered on.
Plug Back In: Reconnect the power cable to the wall so the battery stays fully charged.

Visual Indicators & Control Switches

Status Lights

Label	Light Status	Summary
Battery	Red	Confirm whether the Internet Battery Backup is properly connected to the power supply and the ONT. Check for signs of damage to confirm if the Internet Battery Backup needs to be serviced or replaced. Stop using the Internet Battery Backup and immediately disconnect it and move to a safe area if you notice any of the following: an odor, a change in color, excessive heat, a change in shape, leaking, or odd noises. If it is safe to do so, move the device away from anything that can catch fire. Call 911 if the battery is smoking, extremely hot, or has burst or leaked.
Mute	Yellow	Flashing: The audible alarm is silenced for 24 hours. Solid: The audible alarm is silenced indefinitely.
DC	Green	A power outage is active, and the battery is currently supplying power to your Fiber Jack and router.
System Status	Green	The backup is receiving enough AC power to operate under normal conditions.

Physical Switches

Label	Action
Alarm Silence	Disables audible alerts. Press and release to mute for 24 hours. Press and hold for 15 seconds to mute indefinitely. Hold for another 15 seconds to re-enable the alarm.
Cold Start	Allows the device to turn on without being plugged into a wall outlet (used when there is no AC power and a new battery pack is being installed). Press and hold for 3 seconds.
N.I.R. Reset	This allows you to reboot your Fiber Jack. Press and hold the switch for 3 seconds to reset it.

Safety, Warnings, & Disposal

Stop using the battery backup and immediately disconnect it from the wall if you notice an odor, color change, excessive heat, shape change (swelling), leaking, or odd noises. If safe, move it to a well-ventilated area away from fire hazards. Call 911 immediately if the battery is smoking, extremely hot, burst, or leaking.

Operational Warnings

Indoor Use Only: Install in a dry location. Do not expose to damp or wet environments to prevent fire or electrical shock.
No User-Serviceable Parts: Do not remove the device cover for any reason.
Battery Replacement: Risk of explosion if an improper battery pack is used. Refer to the manufacturer's user manual and use only approved PowerTec battery packs.
Do Not: Disassemble the pack, dispose of it in a fire, or store it in temperatures of 65°C (149°F) or higher.

Disposal & Account Cancellation

Never throw lithium-ion batteries in the trash or leave them in discarded piles. Always dispose of the battery per your local hazardous waste management guidelines from your municipality and contact us to get a replacement. Keep your power supply and power cords – if you decide to change or cancel your plan in the future, you will need to return these to us following these instructions.
Contact GFiber to get a replacement battery if yours is damaged.
Note on Plan Changes: If you cancel your GFiber plan or downgrade in the future, you must return the power supply and power cords to GFiber. Keep these components safe!
