Demand test descriptions and error codes - Avaya Support

Maintenance Demand Tests
For SNC circuit packs, this test determines if the circuit pack can communicate with the other
SNC, and which SNIs the SNC can talk to over the serial communication chel.
This test is run by entering test board or test board long for SNI or SNC circuit packs,
or test fiber-link for fiber links with SNI or EI endpoint(s).
Failures of this test cause entries in the error and alarm logs against Switch Node Configuration
(SN-CONF) with the board location of the SNI or SNC.
For descriptions of result codes for this test, see:
● FIBER-LK Error codes and recommended actions for fiber links.
● SNC-BD Error codes and recommended actions when the circuit pack tested is a Switch
Node Clock (circuit pack slots 10 or 12).
● SNI-BD Error codes and recommended actions when the circuit pack tested is a Switch
Node Interface (circuit pack slots 2–9 or 13–20).
Incorrectly Connected Administered Fibers
Some physically connected fibers that do not match fiber administration can cause port network
problems that are not detected and alarmed by this test. The symptoms will usually be phone
calls not working correctly, and port network component alarms due to translation mismatches.
This test is unable to detect the case where an SNI is connected to the same type of board (EI
or SNI) as administered but located in a different cabinet with the same carrier and same slot as
the administered fiber endpoint. Enter list fiber-link to view the administered fiber
endpoint. This test detects if the fiber endpoint connected to the SNI is in a different carrier and
slot location than the administered fiber endpoint.
Incorrectly Connected SNI-to-EI Fibers
If the SNI is connected to the same type of fiber endpoint as the administered fiber endpoint, but
the location is the same as administered except for the cabinet, every phone call will work
incorrectly; some phone calls will not go through and others will ring the wrong phone.
To check connectivity:
1. Enter test led port-network for each administered port network and verify that the
LEDs on the correct port network are lit.
2. If the LEDS are not lit, enter list fiber-link. Check that the fiber connections to the
port network are consistent with the administered fibers connections of the port network
that does not light the LEDs as expected.
3. Run test led switch-node on each administered switch node carrier and verify that
the LEDs on the correct carrier are lit.
4. If they are not, check the connectivity to the switch node carrier that does not light the
LEDs as expected.
