LED behaviour
4.1
Main LED behaviour
The GW2020 Series router has single colour LEDs for power, config and signal strength.
When the router is powered on, the LED is green.
Figure 2: Power and config LED activity on a GW2021 model: power and config are on
The possible LED states are:
•
Off
•
Flashing slowing
•
Flashing quickly
•
On
Booting
The GW2020 router takes approximately 2 minutes to boot up.
During this time, the power LED is SOLID.
Other LEDs display different diagnostic patterns.
When start up is complete all LED activity will stabilise,
indicating the unit is ready.

LEDs
None
PPP not connected or signal strength <= -113dBm
1
PPP connected and signal strength <= -89dBm
2
PPP connected and signal strength between -89dBm and -
69dBm
3
PPP connected and signal strength >-69dBm

Note: When PPP is not connected, none of the signal LEDs will light regardless of signal
strength.
