The correct support structure should be used to resolve the problem. The 'Trap Error Guidelines' document on the DIAL-IBM database will help the servicer with detailed fault resolution. There are a maximum of 255 possible Traps. An interrupt is an event external to the processor that can occur at random times during system operation. An exception is a special condition which is detected by the processor during the execution of instructions.
Exceptions only occur when the processor is executing instructions.
Traps 0 thru 16, with the exclusion of Trap 2, are special exceptions that are detected by the processor. Trap 2 is a non-maskable interrupt error indicating a catastrophic system failure.
