TIP For combination I/O modules 1746-IO4, 1746-IO8, 1746-IO12 and 1746-IO12DC):
The first several seconds of any powerup or when power is applied to a rack that is
not under processor control, the output LED indicators of the combination input and
output modules in the rack will be illuminated.
Racks are not under processor control if one of the following conditions exist:
• Modular Hardware Style (only): Processor is absent from the rack or the rack
interconnect cable is not properly connected.
• Modular Hardware Style and Fixed Hardware Style: The processor does not have the
firmware PROM installed or the processor is not functioning properly.
