LED and Power Light Meanings on GFiber Devices

The tables in this article provide detailed information about the possible appearances of the LED lights on each device, the possible causes of each state, and what you should do.

Ensure your Fiber Jack is connected to the network and the LED lights are connected and working properly before moving on to troubleshoot your router. Likewise, your router will have to be connected and working properly before you can troubleshoot your other Google Fiber devices.

Models GFLT100, GFLT110, & GFLT300 (1 Light)

Light Status	Cause	Action
Solid red	Powering up or trying to connect to the network.	Wait for the process to complete. If the LED doesn't advance to solid blue within 2 minutes, power cycle the device.
Blinking red	Connecting to the network.	Wait for the process to complete. If the LED doesn't advance to solid blue within 2 minutes, powercycle the device.
Blinking blue	Upgrading device firmware.	Wait for the process to complete. Your service will continue to work during this time, but there may be a brief outage when the device restarts to complete the upgrade. (Firmware updates are usually scheduled in the middle of the night.)
Solid blue	The device is connected to the network and online.	No action required.
No light	No power.	If the device is fitted with a power cable, check the cable and the outlet to be sure it has power. If the device has no power cable, check the Ethernet cable connections and power to the Network Box .

Model GFLT132, GOGP220C, & GOGP222C (4 Lights)

Power LED:

Light Status	Cause	Action
Solid green	Powered on.	No action required.
No light	Power off.	Disconnect the power source from the wall. Then, disconnect the Ethernet cord from the device to which your Fiber Jack is connected. Wait 30 seconds, and plug the Ethernet cord back in. Then reconnect your Fiber Jack to the power source. Wait three minutes for the Fiber Jack to fully reboot.

Alarm LED:

Light Status	Cause	Action
No light	No issues detected.	No action required.
Red light	Loss of signal.	Disconnect the power source from the wall. Then, disconnect the Ethernet cord from the device to which your Fiber Jack is connected. Wait 30 seconds, and plug the Ethernet cord back in. Then reconnect your Fiber Jack to the power source. Wait three minutes for the Fiber Jack to fully reboot.

Optical LED:

Light Status	Cause	Action
Blinking green	Starting up.	No action required.
Solid green	Successfully connected and authenticated.	No action required.
No light or will not stop blinking green	No optical connection or Fiber Jack is ranged but not authenticated.	Disconnect the power source from the wall. Then, disconnect the Ethernet cord from the device to which your Fiber Jack is connected. Wait 30 seconds, and plug the Ethernet cord back in. Then reconnect your Fiber Jack to the power source. Wait three minutes for the Fiber Jack to fully reboot.

Network LED:

Light Status	Cause	Action
Blinking green	Traffic is passing successfully.	No action required.
Solid green	A device is connected but not passing traffic.	Disconnect the power source from the wall. Then, disconnect the Ethernet cord from the device to which your Fiber Jack is connected. Wait 30 seconds, and plug the Ethernet cord back in. Then reconnect your Fiber Jack to the power source. Wait three minutes for the Fiber Jack to fully reboot.
No light	LAN Port is not connected to a device.	Make sure that the Ethernet cable is securely connected.

Confirm that your Fiber Jack is solid blue before moving on to this step.

Light Status	Cause	Action
Solid red or purple	Powering up.	Normal for a several seconds during power-up. If the LED does not advance to solid blue within 2 minutes, power cycle the device. If either the red or purple LED remain solid for an extended period, contact GFiber customer support.
Blinking red	Disconnected from the network.	If the LED does not advance to solid blue within 2 minutes, check to make sure the Ethernet cable between the Network Box and Fiber Jack is connected.
Slow blinking blue (1 second on, 500ms off)	Connecting to the network or upgrading device firmware.	Wait for the process to complete. If the LED does not advance to solid blue within 2 minutes, check that the Fiber Jack has a solid blue LED.
Fast blinking blue (500ms on, 500ms off)	Connected to the network but unable to reach Google Fiber servers.	Wait for the process to complete. If the LED does not advance to solid blue within 2 minutes, power cycle the Network Box. If the Network Box continues to blink quickly, contact Google Fiber customer support.
Solid blue	The device is connected to the network and online.	No action required.
No light	No power.	Check the power cord and the outlet to be sure it has power.
