The LED colors and patterns give you a quick reading of the router’s status.
To reduce the router’s power consumption, you can turn off the LEDs by going to System > LEDs > LED Powersaver Mode and clicking ENABLE.

Patterns
Solid: Single color, always on
Fast flashing: One color on for 0.2 s, then off or another color for 0.2 s
Slow Flashing: One color on for 0.25 s, then off or another color for 0.75 s
Pulse: One color on for 0.5 s, then a 0.2 s pulse off or another color
Chase: All LEDs on for 0.2 seconds in sequence from left to right, continuously
You can adjust the timing of the Fast Flashing, Slow Flashing and Chase patterns under System > LEDs > LED Pattern.
GNSS
Solid Green
Satellite fix is available and Dead Reckoning is enabled and calibrated (Dead Reckoning calibration occurs occasionally during driving and takes several minutes to complete) or
Satellite fix is available and Dead Reckoning is disabled
Solid Yellow
Satellite fix is available and Dead Reckoning is enabled but not calibrated
Solid Red
Searching for a satellite fix
Fast Flashing Red
GNSS antenna is open or shorted.
Note: Antenna may appear to be connected but is drawing either more electrical current or less electrical current than considered normal or expected.
Slow Flashing Red
GNSS antenna is disconnected.
Note: Electrical current is drawing below predefined threshold.
Off
GNSS is off or disabled
WI-FI
Solid Green (pulse off with activity)
Connected in client mode (good signal) with traffic
Note: If AP has traffic at the same time, LED displays the client status (i.e. displaying a connected depot is the priority)
Slow Flashing Green
Wi-Fi client is enabled but not connected, and no AP is enabled
Solid Yellow (pulse off with activity)
Connected in client mode (fair signal) with traffic
Note: If AP also has traffic at same time, LED displays the client status (i.e. displaying a connected depot is the priority)
Solid Red (pulse off with activity)
Connected in client mode (poor signal) with traffic
Note: If AP also has traffic at same time, LED displays the client status (i.e. displaying a connected depot is the priority)
Solid Purple (pulse off with activity)
AP with traffic, and Wi-Fi client enabled but no connection or
AP with traffic, and Wi-Fi client disabled
Slow Flashing Purple
AP enabled but not connected
Off
No Wi-Fi enabled (no AP, no Wi-Fi client)

Solid Green (pulse off with activity)
Connected to a 4G/3G network with a good connection (equivalent to 4–5 bars)
Slow Flashing Green
Connecting to a 4G/3G network
Solid Purple (pulse off with activity)
Connected to a 5G network with a good connection (equivalent to 4–5 bars)
Slow Flashing Purple
Connecting to a 5G network
Solid Yellow (colored pulse with activity)
Connected to a network with a fair connection (equivalent to 2–3 bars). During activity, RAT (5G or 3G/4G) is indicated by a pulse color:
Green pulse: 4G/3G
Purple pulse: 5G
Solid Red (colored pulse with activity)
Connected to a network with a poor connection (equivalent to 1 bar). During activity, RAT (5G or 3G/4G) is indicated by a pulse color:
Green pulse: 4G/3G
Purple pulse: 5G
Slow Alternating Flashing Red/Yellow
Network Operator Switching is enabled, but the required radio module firmware is not currently available on the router. For more information, see Radio Module Firmware Image Management.
Slow Flashing Red
No network connection
Off
No expansion cartridge installed
LPWA
Solid Green (pulse off with activity)
LPWA connected to a network and ALMS with a good connection (equivalent to 4–5 bars)
Slow Flashing Green
Connecting to a network
Solid Yellow (pulse off with activity)
Connected to a network and ALMS with a fair connection (equivalent to 2–3 bars)
Solid Red (pulse off with activity)
Connected to a network and ALMS with a poor connection (equivalent to 1 bar)
Slow Flashing Red
No network connection
Off
LPWA module powered off
POWER
Solid Green
Router operating normally with ignition on
Fast Flashing Green
Router is rebooting after Reset button pressed for <5 seconds (or reset from AirLink OS)
Solid Yellow
Router is booting or
the router is thermally throttled — one or more of CPU, cellular radio, and Wi-Fi radio has exceeded threshold. When operating temperature returns to normal, LED returns to solid green.
Fast Flashing Yellow
Router is rebooting and being reset to factory defaults, after Reset button is pressed for 20–40 seconds
Solid Red
Power is present, but the router is not running (e.g. ignition is off, router is in standby mode, etc.)
Note: If the router is in standby mode, the Power LED will be solid red only if the AirLink OS Standby LED setting is enabled (System > MCU > Power Management), otherwise the LED will be Off. (By default, the setting is enabled.)
Fast Flashing Red
Router is rebooting and being reset to the specified Reset Configuration Type, after Reset button pressed for 5 to 20 seconds.
Slow Flashing Red
Router is not operating because operating temperature range is exceeded (i.e. thermal shutdown)
Fast Alternating Flashing Yellow/Red
Reset button held > 40 seconds, canceling the reset action and rebooting normally when released. (i.e. if pressing the reset button for more than 5 seconds, and you decide that the router should do a regular reboot [not a reset to default template or factory defaults] continue pressing Reset until the LED flashes Yellow and Red)
Off
No power or the router is in standby mode and the AirLink OS Standby LED setting is disabled (System > MCU > Power Management)
All LEDs
A yellow LED chase pattern indicates a software update in progress (a XR router firmware update, radio module
firmware update, etc.)
Important: Do not turn off the power while the update is in progress.
A green LED chase pattern indicates a radio module firmware update or radio module firmware switch in progress. For more information, see Radio Module Firmware Image Management.
