Active Indicator
The ACTIVE indicator lights when the module has started up and
successfully initialized.
The module also has 16 indicators (on the right side of the display)
that display a blown-fuse condition at the respective output
regardless of the state of the output. These indicators are driven by
your ac power supply. The FUSE blown indicators will reset after the
fuse has been replaced and chassis power has been cycled.
