SNC-BD (Switch Node Clock Circuit Pack)
Issue 1 June 2005 2029
Failure Audit (#777)
This test is nondestructive.
This test queries an SNC for any existing failures and any unacknowledged “cleared failure”
messages. Each failure generates an error and alarm entry against SNC-BD, SNC-LINK, or
SNC-REF. A “cleared failure” message is a message an SNI circuit pack sends to software
indicating the resolution of a previous failure. This message is “unacknowledged” if the SNI
circuit pack never receives a response from software indicating it’s own receipt of the original
“cleared failure” message.
If no failures are detected by the SNC circuit pack, this test will pass.
If this test reports failures, the test board screen shows FAIL with no FAIL code. Use
display errors pnc to show the error log and view SNC-related errors: SNC-BD,
SNC-LINK, and SNC-REF.
