Figure 4-1: Status LED Locations
Two large LEDs on the front of the main board indicate the general health of the module.
LOCAL FAULT: This Red LED indicates poor module health and will be ON during the absence of a
valid input signal or if a local input power fault exists (i.e.: a blown fuse). The
LOCAL FAULT indication can also be reported to the frame through the FRAME
STATUS jumper.
MODULE OK: This Green LED indicates good module health. It will be ON when a valid input
signal is present on all inputs, and the board power is good.
These four surface mount LEDs indicate valid signal presence on the respective inputs.
