Understanding the Front Panel Indicators

Indicator charts

Normal operations (power up)

The following chart illustrates the sequence of steps and the corresponding appearance of the modem front panel LED status indicators during power up, calibration, and registration on the network when AC power is applied to the modem.. Use this chart to troubleshoot the power up, calibration, and registration process of your modem..

Note

After the modem completes Step 7 (Data Network Registration Complete), the modem proceeds immediately to Normal Operations.. See Normal Operations below..

Understanding the Front Panel Indicators

Normal operations (AC power applied)

The following chart illustrates the appearance of the modem front panel LED status indicators during normal operations when AC power is applied to the gateway..

Front panel LED status indicators during normal conditions
Front panel		Normal operations
indicator
1	POWER	On
2	DS	On
3	US	On
4	ONLINE	On
		ON - When a single device is connected to the Ethernet port and no data is
		being sent to or from the modem..
5	LINK	BLINKS - When only one Ethernet device is connected and data is being
		transferred between the consumer premise equipment (CPE) and wireless
		home gateway..
		OFF - When no devices are connected to the Ethernet ports

Note

In addition to the above indicators, some service providers use color-coded LEDs to indicate detailed channel bonding and data link status.. For additional information about color-coded LEDs, check with your service provider..

Special conditions

The following table describes the appearance of the modem front panel LED status indicators during special conditions to show that you have been denied network access..

Front panel LED status indicators during special conditions

Front Panel Indicator		Network Access Denied
1	POWER	Slow blinking (once per second)
2	DS	Slow blinking (once per second)
3	US	Slow blinking (once per second)
4	ONLINE	Slow blinking (once per second)
5	LINK	Slow blinking (once per second)
