Maintenance Objects

3-709IO-PROCR (I/O Processor)

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.
