System Technician-Demanded Tests:
Descriptions and Error Codes
Always investigate tests in the order presented in the following tables when
inspecting errors in the system. For example, by clearing error codes associated
with the Control Channel Loop Around test (#52), you may also clear errors
generated from other tests in the testing sequence.
NPE Audit Test (#50)
See the repair procedure described in XXX-BD (Common Port Circuit Pack) as
‘‘NPE Connection Audit Test (#50)’’ on page 8-1733 .
Control Channel Loop Around Test (#52)
See the repair procedure described in XXX-BD (Common Port Circuit Pack) as
‘‘Control Channel Loop-Around Test (#52)’’ on page 8-1734 .
SAKI Sanity Test (#53)
Refer to the repair procedure described in XXX-BD (Common Port Circuit Pack)
as
‘‘SAKI Sanity Test (#53)’’ on page 8-1735 .
LANBIC Receive Parity Error Counter Test (#595)
This test is destructive.
The test reads and clears the LANBIC Receive Parity Error Counter on the circuit
pack. This counter is incremented by the circuit pack when it detects a parity error
in data received from the packet bus.
These errors may indicate a circuit-pack problem, packet-bus problem, or a
problem with another circuit pack on the bus. This test is useful for verifying the
repair of the problem.
