Result
101 FAIL The SNC circuit pack has on-board microcontroller failure.
1. Replace the SNC circuit pack.
128 FAIL The SNC circuit pack has a problem with its clock. Firmware has
detected a phase-locked loop failure, an inability to lock, or a failure of
the clock drivers.
1. Replace the SNC circuit pack.
129 FAIL The SNC circuit pack has a problem with the SNC on-board Stratum-3
oscillator.
1. Replace the SNC circuit pack.
130 FAIL The SNC circuit pack has a problem with the TPN microcontroller.
1. Replace the SNC circuit pack.

TPN Test (#779)
Description / Recommendation
PASS No problems exist with the on-board functions verified by this test.
No board was detected by the test.
2. Check that SNC board is properly translated and inserted.
3. Run the test again. If it fails, reset the board. An SNC should be
reset instead of reseating the circuit pack. The reset board
command should almost never be used on an SNC. It may be
necessary to use reset board if the SNC circuit pack gets into
a mode where it cot communicate with software. If an SNC with
active errors and alarms is reset, the errors and alarms may take
a while to come back, therefore reset board can mask real
problems.
4. Run the test again. If it fails, the ID chip on board may be bad.
Replace the board and retest.
This test queries the SNC circuit pack for the status of the ROM and internal RAM background
tests for the TPN microcontroller.
