During the Boot process, the Power light will be Flashing Green while all the other lights will be Off.
However:
• If the device does not Boot and fails its self-test or fails to perform initial load of the bootloader:
The Power light will be Flashing Red, while all the other lights will be Off.
• If the device Boots and then detects a failure:
The Power light will be Flashing Green starting POST, and then all the lights will Flash Red, including Power light.

Solid Green | IP connected. The device has a WAN IP address from DHCP or 802.1x authentication and the broadband connection is up. | |
Flashing Green | Attempting connection, attempting IEEE 802.1X authentication, or attempting to obtain DHCP information. | |
Solid Red | Device attempted to become IP connected and failed (no DHCP response, 802.1x authentication failed, no IP address from IPCP, etc.). The Red state times out after two minutes, and the Service indicator light returns to the Off state. |
Status light | State | Meaning |
Phone 1,2 | Off | VoIP not in use, line not registered, or gateway power off. |
Solid Green | The associated VoIP line has been registered with a SIP proxy server. | |

Solid Green | Wi-Fi Protected Setup has been completed successfully. LED should stay on for 5 minutes or until push button is pressed again. | |
Flashing Green | Continues for 2 minutes, indicating when WPS is broadcasting. | |
Flashing Red | Continues for 2 minutes, indicating a Session overlap was detected (possible security risk). | |
Solid Red | Error unrelated to security, such as failure to find a partner, or WPS is disabled. LED should stay solid Red for 5 minutes or until push button is pressed again. |
During the software installation, you will lose internet and phone service. The status lights will function as follows:
1. As firmware is being loaded into flash, the status lights will operate normally as described.
2. The installation will take a few minutes. During this phase, the Power light will flash Orange/Amber during firmware upgrade (flash writing to memory) and all other lights will be off.
3. The gateway will restart automatically. As the device reboots, the POWER ON status light behavior will happen.
