If the self-test failed, the red LED will flash three times and then remain lit.

See the 8400B Plus Data Module User Guide to resolve configuration

• Check the connections and wiring.

• Check the data module optioning.

• Test the data module from the DEFINITY system

using the “Status Data” switch command. You must

enter the data module extension number.
