SNC-BD (Switch Node Clock Circuit Pack)
Issue 1 June 2005 2031
SNC On-Board Test (#778)
This test is nondestructive.
This test queries the SNC circuit pack for status of the background tests run on-board. These
background tests include an SNC on-board microcontroller test, clock test, an SNC on-board
Stratum-3 oscillator test, and TPN microcontroller test.
0NO
BOARD
No board was detected by the test.
1. Check that SNC board is properly translated and inserted.
2. 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
cannot 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.
3. Run the test again. If it fails, the ID chip on board may be bad.
Replace the board and retest.
