2. If no other I/O Processor errors appear in the error log, and if the I/O
Processor is not in a held reset state as indicated by the absence of
a MAJOR alarm with a Service State of OUT, no action should be
taken.
b. Error 257 indicates that an in-line error (IOP System Error) has been
reported by I/O Processor firmware. When this error counter is active, the
error count is decremented by 1 every 15 minutes, but only if the I/O
Processor has not been reset three times by background maintenance. If
the threshold is exceeded, a MAJOR alarm is raised. Execute a demand
reset by entering
reset io-processor
and refer to the repair procedures
for Test # 704.
c. Error 513 indicates that an in-line error (IOP Handshake Failure) has been
reported by I/O Processor driver when the driver is unable to check the
sanity of the firmware. When this error counter is active, the error count is
decremented by 1 every 15 minutes, but only if the I/O Processor has not
been reset three times by background maintenance. If the threshold is
exceeded, a MAJOR alarm is raised. Execute a demand reset by entering
reset io-processor
and refer to the repair procedures for Test # 704.
System Technician-Demanded Tests:
Descriptions and Error Codes
The I/O Processor support both the Data Channel data scanners and Packet
Interface functions. Running the I/O Processor Reset Test is as though both the
Data Channel Reset Test and Packet Interface Reset Test are executed along
with a reset of the I/O Processor CPU, memory, and real time operating system.
Demand Reset Test (#704)
This test is destructive.
This action initializes the I/O Processor, and the firmware runs a comprehensive
set of diagnostic tests. This action will abort if the I/O Processor is in the
in-service state. The I/O Processor is put in the out-of-service state automatically
if it has been reset three times by background maintenance within the last 15
minute, independent of the reset action.
