OK LED: Blink Pattern Error Indication
When the TGW-100 is powered up, the OK LED should be constantly “on” to indicate
the proper device operation.
If this LED is flashing or off, it indicates an exception. Different “blinking codes” can
indicate different problems as shown in the table below:
Blink Pattern

Controller (CPU sub-module) fault or the modem is not in
"Ready" state.
