1. Indicates that an alarm was raised but an associated error was not entered into the hardware error
log due to a momentary overload condition caused by a burst of hardware or software error reports.
Run the long test sequence. Refer to the appropriate test descriptions for any failures and follow the
recommended procedures.
2. An I/O Processor can only be reset if it has been taken out of service by background maintenance
software.
Notes:
a. Error 1 occurs when background maintenance software has reset the I/O
Processor as a fault recovery action. It is used to track the number of IOP
resets, independent of whether or not the Reset test passed. Once three of
these errors have occurred in the last 15 minutes, maintenance places the
I/O Processor in the out-of-service state, and a MAJOR on-board alarm is
raised on the I/O Processor. When the I/O Processor has been taken
out-of-service, the Packet Interface and Data Channels are also taken
out-of-service.
1. Check to see if error codes 257 or 513 are present in the hardware
2. If no other I/O Processor errors appear in the error log, and if the I/O
