GW2020 Series router LED behaviour
3.1
Main LED behaviour
The GW2020 Series router has single colour LEDs for Power, Config, SIM1, SIM2 and
signal strength. When the router is powered on, the LED is green.
Figure 3: Example of power and config LED activity: power and config are on
The possible LED states are:
•
Off
•
Flashing slowing
•
Flashing quickly
•
On
The following table describes the possible LED behaviour and meanings.
Booting
The GW2020 takes approximately 2 minutes to boot up. During this
time, the power LED flashes.
Other LEDs display different diagnostic patterns during boot up.
Booting is complete when the power LED stops flashing and stays on
steady.
Power LED
On
Power connected.
Off
No power/boot loader does not exist.
Config LED
On
Unit running a valid configuration file.
Flashing slowly
Unit running in recovery mode (5 Hz).
Flashing quickly
Unit running in factory configuration (2.5 Hz).
SIM LEDs
On
SIM selected and registered on the network.
Off
Not selected or SIM not inserted.
Flashing
SIM selected and data connection is being established.
Signal LEDs
None
Not connected or signal strength <= -113dBm.
1
Connected and signal strength <= -89dBm.
2
Connected and signal strength between -89dBm and -69dBm.
3
Connected and signal strength >-69dBm.
Table 6: LED behaviour and descriptions
Note: when a data connection does not exist, none of the signal LEDs will light
regardless of signal strength.
