IO-PROCR (I/O Processor)
The I/O Processor includes the I/O Processor CPU, memory, a real-time
operating system, and a driver. Together they support the Data Channel data
scanners and Packet Interface functions. The I/O Processor resides on the single
TN798 Processor circuit pack in the system.
Error Log Entries and Test to Clear Values
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
error log. If one or more of those error codes are present, refer to
the information associated with those errors for the appropriate
repair procedures.

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.
