Solutions

The solutions are listed in order: the solution most likely to fix the problem is listed first. Work through each solution until the problem is resolved.

• Check if you have exceeded the total I/O Bus addressing power limits. For more information, see Power Budget .

• If the power limit has been exceeded, insert another power supply in a suitable position among the devices to reduce the power load on the original power supply. See the illustration below.

• If you have NOT exceeded the power limits, inspect for failed I/O modules. A failed module could be drawing too much current and sending the power supply into overcurrent protection mode.

• Remove/replace failed or less important I/O modules until power consumption has decreased to an acceptable level.
