Checking the LED Indicators
The card provides three bi-color LED indicators to show the state of the
system. The LEDs are located on the mounting bracket of the 1784-PM16SE
card. The LED on the top, marked by OK, indicates the present health of the
card. Just below the OK LED is the SERCOS Ring Status LED. This is
marked with a ring icon and displays the status of the SERCOS network.
