The front panel of your module contains one green, module active
indicator, 16 red status indicators and one red fuse-blown indicator.
The 1771-OMD/B performs diagnostics in a handshaking mode
when first powered up. Upon successful completion of the
diagnostics, the green module active indicator lights. It turns off if a
fault occurs in the data paths or the opto-isolators.

The red status indicators are provided for system logic side
indication of individual outputs. When a red status indicator lights,
voltage is present on the terminal.

The red fuse-blown indicator is lit when the fuse in the module has
cleared or been removed.
