Status Indicators and Module Label
After the module has been inserted into a terminal base (and power
is applied), the green POWER indicator turns on and the
FP-DO-400 informs the network module of its presence. When
the network module recognizes the FP-DO-400, it sends initial
configuration information to the FP-DO-400. After receiving this
initial information, the green READY indicator turns on and the
FP-DO-400 is in its normal operating mode. In addition to the
green POWER and READY indicators, each channel has a
numbered, green, output state indicator which lights when the
channel is in the ON state.
