NATI Boards showing streaming red lights

[Nortelshop]

What does it mean when the red lights are populating from right to left in a sequence fashion on the logger? i relaize it is an NATI board error, but do I need to replace those (NATI boards) as they have gone bad. the logger states reboot system as NATI board channel errors showing up, I reboot, but it doesn't help. Can someone tell me if I need to replace the NATI boards? And if not, then what do I need to do to test them or correct this issue. Thanks in advance for your help!!!!!

What error shows in Supervision? The red lights on the NATI board itself just means there's a channel error on the channels. There's one LED for each group of 8 channels.
