Gateway status lights - NVG599

The following chart explains each status light and what it means.



NVG599 status lights 

Status Light	State	Description
Power	Off	The unit has no AC power. If the battery is in use, the Battery LED will indicate battery status, and all other LEDs will be off.
	Solid Green	The device is powered on.
	Flashing Green	A Power-On Self-Test (POST) is in progress.
	Flashing Red	A POST failure (not bootable) or device malfunction occurred.
	Flashing Amber	Firmware upgrade in progress (see below).
All during Boot process		Power light = Flashing Green All other lights = Off If the device does not boot and fails its self-test or fails to perform initial load of the bootloader: Power light = Flashing Red ALL other lights = Off If the device boots and then detects a failure: Power light = Flashing Green starting POST, and then all lights will flash red, including Power light.
Battery	Off	No battery or battery has no charge.
	Solid Green	Battery in place but not being used.
	Flashing Green	Battery charging.
	Solid Red	Battery backup mechanism has a fault.
	Flashing Red	Battery needs to be replaced.
	Solid Amber	Battery in use.
	Flashing Amber	Low battery.
	Cycle between all colors	Battery conducting self-test.
Ethernet	Off	The device is not powered, or no cable or no powered devices are connected to the associated ports.
	Solid Green	Powered device connected to the associated port (includes devices with wake-on-LAN capability where a slight voltage is supplied to the Ethernet connection).
	Flickering Green	Activity seen from devices associated with the port. The flickering of the light is synchronized to actual data traffic.
Wi-Fi	Off	The device is not powered, or no powered devices are connected to the associated ports.
	Solid Green	Wi-Fi is powered.
	Flickering Green	Activity seen from devices connected via Wi-Fi. The flickering of the light is synchronized to actual data traffic.
HomePNA	Off	The device is not powered, or no cable or powered devices are connected to the associated ports.
	Solid Green	Powered device connected to the associated port (includes devices with wake-on-LAN capability where a slight voltage is supplied to the Ethernet connection).
	Flickering Green	Activity seen from devices associated with the port. The flickering of the light is synchronized to actual data traffic.
Broadband 1, 2	Off	The device is not powered.
	Solid Green	Good broadband connection (good DSL sync or Gigabit Ethernet).
	Flashing Green	Attempting broadband connection (DSL attempting sync).
	Flashing Green & Red	If, after three consecutive minutes, the broadband connection fails to be established, the LED switches to Flashing Green alternating with a five second steady Red while attempting or waiting to establish a broadband connection. This pattern continues until the broadband connection is successfully established.
	Flashing Red	No DSL signal on the line. This display is not used during times of temporary no tone during the training sequence.
Broadband 1	Broadband 1 LED is also the Gigabit Ethernet WAN LED when that is in play (and DSL is not).
Service	Off	The device is not powered or the broadband connection is not present.
	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.
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.
	Flashing Green	Indicates a telephone is off-hook on the associated VoIP line.
USB	Off	The device is not powered, no cable or no powered devices connected to the associated ports.
	Solid Green	Powered device connected to the associated port (includes devices with wake-on-LAN capability where a slight voltage is supplied to the Ethernet connection).
	Flashing Green	Activity seen from devices associated with the port. The flickering of the light is synchronized to actual data traffic.
WPS (appears after using WPS button)	Off	The device is not powered, or no cable or no powered devices are connected to the associated ports.
	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.

Status lights during firmware upgrades
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.
