Determining Whether or Not a PCI-6528 is Receiving 3.3 Volt Power

Hardware: Digital I/O (DIO)>>Isolated>>PCI-6528

Problem:
I have a PCI-6528 in an Industrial PC (IPC), but I don't know if the IPC supports universal PCI by providing a 3.3 V line for my PCI bus.

Solution:
On the PCI-6528 there is a small LED (DS1) at the top of the board near the middle. If this LED is lit, then the 3.3 V line has power; otherwise, the 3.3 V line does not have power and the PCI-6528 will not function properly in that IPC.

When plugged in to a computer with the proper power rails the LED is clearly visible as seen below.
