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 indic ated 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 fir mware. 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 b ackground 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 bee n
reported by I/O Processor d river when the driver is unable to c heck the
sanity of the firmware. When this error counter is active, the error c ount is
decremented by 1 every 15 minutes, but only if the I/O Processor has not
been reset three times by bac kground maintenance. If the threshold is

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 firmw are runs a comprehensive
set of diagnostic tests . This action will abort if the I/O Processor is in the

if it has been reset three times by b ackground maintenance wit hin the last 15
minute, independent of the reset action.
