System Technician-Demanded Tests: Descriptions
and Error Codes
When inspecting errors in the system, always investigate tests in the order listed
below. By clearing error codes associated with the Control Channel Loop Around
Test, for example, you may also clear errors generated from other tests in the
testing sequence.
Control Channel Loop Around Test (#52)
Refer to the repair procedure described in the
‘‘XXX-BD (Common Port Circuit
Pack)’’
section.
NPE /NCE Audit Test (#50)
Refer to the repair procedure described in the
‘‘XXX-BD (Common Port Circuit
Pack)’’
section.
SAKI Sanity Test (#53)
This test is destructive.
Refer to the repair procedure described in the
‘‘XXX-BD (Common Port Circuit
Pack)’’
section. This test is only run as a part of a reset board procedure.
LAN Receive Parity Error Counter Test (#595)
This test is nondestructive. The test reads and clears the circuit pack’s LAN
Receive Parity Error Counter. This counter increments when it detects a parity
error from the Packet Bus. These errors may indicate problems with a circuit pack,
Packet Bus, or with another circuit pack on the bus. Use this test to verify the
repair.
