System Technician-Demanded Tests:
Descriptions and Error Codes
When inspecting errors in the system, always investigate tests in the order listed
below. 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.
Control Channel Loop-Around Test (#52)
See the repair procedure described in ‘‘XXX-BD (Common Port Circuit Pack)’’ on
page 8-1872.
NPE /NCE Audit Test (#50)
See the repair procedure described in ‘‘XXX-BD (Common Port Circuit Pack)’’ on
page 8-1872.
SAKI Sanity Test (#53)
This is a destructive test.
See the repair procedure described in ‘‘XXX-BD (Common Port Circuit Pack)’’ on
page 8-1872. 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.
