PI-PT (Processor Interface Port)
Issue 4 May 2002
10-1249555-233-123
Notes:
a. PI-LINK raised this alarm against PI-PT. The Processor Interface Loop
Around test failed on one of the ports. Refer to PI-LINK Maintenance
documentation for details on resolving this alarm. If this error resulted in an
SPE-interchange, then issue the test interface PCS sh command on the
Standby Processor Interface to try to resolve the alarm.
b. This error type indicates that the circuit pack has been removed or has
been insane for more than 11 minutes. To clear the error, reinsert or
replace the circuit pack.
System Technician-Demanded Tests: Descriptions
and Error Codes
PI-PT can be tested by issuing the test interface PCS command on the Standby
Processor Interface circuit pack. If the Active TN765 Processor Interface circuit
pack is tested, then the active test sequence is run (which is DESTRUCTIVE).
[Refer to PI-SCI (System Communication Interface) Maintenance documentation
for details on these tests]. Only the Standby Processor Interface test sequence
runs tests directly on PI-PT.
Always investigate tests in the order presented in the table below when inspecting
errors in the system. By clearing error codes associated with the Standby
Processor Interface Port Test, for example, you may also clear errors generated
from other tests in the testing sequence.
Notes:
a. Refer to “XXX-BD (Common Port Circuit Pack)” for information about these
tests.
b. Refer to “PI-BD” for information about this test.
