Checking the modem indicator lights and modem power…
If you can get physical access to the 3100-iSIC, underneath the iSIC mounting plate is an Airlink
Raven modem. This modem has status lights that indicate if the modem has power, signal, etc.
The light on the far right is the power light, indicating that the iSIC is powering the modem. If
this is not on try cycling power to the iSIC by removing the two fuses and putting them back in.
Make the fuses are not blown and that the iSIC is still receiving power. You can verify this by
watching for the green blinking light in the LED hole as described in the “First Steps” section.
The three lights to the far left should be solid green. They represent the Channel, Link, and
Register lights. You will notice after power is cycled to the modem that first the Channel light will
come on, then the Link light, and then the Register light. If all three lights are blinking, or the
Register light never becomes solid then the modem is unable to register to the network. Make
sure the modem was provisioned and that you have proper signal strength.
The remaining lights in the center may occasionally blink and represent data communication
happening between the modem and the network.
