• processor detects a runtime error
• an I/O chassis backplane fault occurs
• you select program or test mode
• you set a status file bit to reset a local rack
2. If an EEPROM module is not installed and processor memory is valid, the processor's PROC LED indicator blinks,
and the processor sets S:11/9, bit 9 in the major fault status word.
