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.

NO
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 the reset
board command 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 the
reset board command 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.
