Gateway status lights - NVG510

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



NVG510 status lights

Light	Status	Indicates
Power	Off	The unit has no AC power.
	Solid Green	The device is powered on.
	Flashing Green	Power-On Self-Test (POST) is in progress.
	Flashing Red	A POST failure (not bootable) or device malfunction occurred. When the device encounters a POST failure, all indicator lights on the front of the device continuously flash.
Ethernet	Off	The gateway power is off, There are no powered devices connected to the Ethernet 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).
Wireless	Off	The gateway power is off. There are no powered devices connected to Wi-Fi.
	Solid Green	Wi-Fi is powered on.
	Flickering Green	Activity seen from devices connected via Wi-Fi (the flickering of the light is synchronized to actual data traffic).
Wi-Fi Setup	Off	Wi-Fi is not in use or not broadcasting.
	Flickering Green	Indicates WPS is broadcasting.
Broadband	Off	The gateway power is off.
	Solid Green	There is a good broadband connection (i.e., good DSL Sync).
	Flashing Green	The gateway is attempting a broadband connection (i.e., DSL attempting sync).
	Flashing Green and Red	If the broadband connection fails to be established for more than three consecutive minutes the LED switches to Flashing Green when attempting or waiting to establish a broadband connection alternating with a five second steady Red. This pattern continues until the broadband connection is successfully established.
	Flashing Red	There is no DSL signal on the line. This is only used when there is no signal, not during times of temporary no tone during the training sequence.
Service	Off	The gateway power is off, or the broadband connection is not present.
	Solid Green	IP connected (i.e., the device has a WAN IP address from DHCP or 802.1x authentication and the broadband connection is up).
	Flashing Green	The gateway is attempting PPP connection, attempting IEEE 802.1X authentication, or attempting to obtain DHCP information.
	Solid Red	The gateway attempted to become IP connected and failed (no DHCP response, no PPPoE 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 is not in use, line is not registered, or the gateway power is 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.

Status lights during firmware upgrades
Firmware updates keep your Wi-Fi gateway running smoothly.  During the software installation, you’ll lose internet and phone service.
The lights will function as follows:

• As firmware is being loaded into flash, the lights will operate normally as described above.
  
• The installation may take a few minutes. During this phase, the Power light will be Solid Green, the Ethernet light will be Solid Green, and the rest of the lights (Wireless to Phone 2) will flash Solid Green one after the other moving from top to bottom and then bottom to top.

The gateway will restart automatically. As the device reboots, the POWER ON light behavior will happen.
