Intelligent Network Device (iNID) Power Supply Unit

Use the following table to interpret the indicator lights on your Intelligent Network Device (iNID) power supply:

Status lights for iNID Power Supply Unit

Light	Status	Indicates
Power	Off	Power supply is not receiving power from either AC or the battery.
	Solid Green	Power supply is running on AC power.
	Flashing Red	Power is provided by the backup battery or the outside unit is not yet communicating with the iPSU.
Battery	Off	No battery installed.
	Solid Green	Battery is installed and functioning properly.
	Flashing Red	Battery needs to be replaced.

Button functions for iNID Power Supply Unit

Button	Location	Function
Reset Button	Upper left side panel, identifiable by a surrounding red circle	When pressed for up to 9 seconds, the Reset button reboots the outside unit. If the button is pressed for 10 or more seconds, it resets the outside unit to the factory settings. Do not press the Reset button unless you are instructed to do so. Doing so may reset the outside unit to the factory default settings, and you will lose your personal settings.
Silence Alarm Button	Between the Power and Battery indicators	If AC power is interrupted for any reason, a continuous tone indicates that the power supply is running on the backup battery. Pressing the Silence Alarm button within 15 seconds immediately silences the audio alert. (The tone stops automatically after 15 seconds). When the battery needs to be replaced, a chirp sounds intermittently unless you press the button to silence it for 12 hours. The chirp resumes after 12 hours if the battery is not replaced.

Intelligent Network Device (iNID) Outside Unit
Use the following table to interpret the indicator lights on your Intelligent Network Device (iNID) outside unit:


Status lights for iNID Outside Unit

Status Light	State	Description
Power The Power indicator turns red when the power is first applied, and changes to green within two minutes of power application.	Solid Green	Power is on and initialization has been completed successfully.
	Flashing Green	The iNID is booting.
	Solid Red	A Power-On-Self-Test (POST) failure (unbootable) or another malfunction (for example, alarm) has occurred during self initialization.
VDSL 1 and VDSL 2 These two indicators flash after 60 seconds of power application for 1 to 2 minutes and cycle three times. The Broadband indicator on the 2WIRE 3801 HGV-B mirrors one or both of the VDSL indicators, whichever is in the best state.	Solid Green	The broadband connection is trained.
	Flashing Green	The broadband connection is being attempted (DSL attempting to synchronize).
	Alternating Flashing Green and Steady Red	The broadband connection failed to establish for more than three consecutive minutes. This pattern continues until the broadband connection is successfully established.
	Flashing Red	No DSL signal on the line.
Data	Solid Green	A device is connected (such as a 2WIRE 3801 HGV-B).
	Flickering Green	There is inbound activity associated with the data port (that is, the green Line 1 connection) - the flickering of the light is synchronized to the actual data traffic.
	Solid Red	A device failed to be authenticated or successfully connected.
Coax	Solid green	A device is connected (such as a Set Top Box).
	Flickering Green	There is inbound activity associated with the COAX port (the flickering of the light is synchronized to the actual data traffic).
		A device failed to be authenticated or successfully connected.
Line 1 and Line 2 These two indicators mirror Line 1 and Line 2 indicators on the i38HG	Solid Green	The associated VoIP line has been registered with the network and ready for use.
	Flashing Green	A telephone is in use on the associated VoIP line.
Ethernet	Solid Green	A device (such as a computer) is connected to the Ethernet port.
	Flickering Green	Data traffic from devices connected to the Ethernet port (the flickering of the light is synchronized to the actual data traffic).
Battery	Solid Green	The AC power is connected and healthy.
	Flashing Red	The backup battery is used for power.
