SNI Destructive Facility Test (#757)
This test is destructive.
The SNI runs a destructive loop around of the on- and off-board loop arounds.
This test returns the result of the on-board loop around, while Test 756 returns the
result of the off-board loop around.
For SNI-to-SNI fiber links, this test is run on both SNI circuit pack endpoints of the
fiber link.
227
FAIL
The data is not correctly looped around on Endpoint 2 of the fiber link (list
fiber-link can be used to display fiber link endpoints).
1. Check the lightwave transceiver.
2. Replace the lightwave transceiver. If a fiber out-of-frame condition exists
and lightwave transceivers are used, check that the lightwave transceivers
are of the same type (both are 9823a or both are 9823b). If they are not
the same type, replace one of the lightwave transceivers.
3. Replace the SNI circuit pack.
PASS
No problems associated with this test are detected on the SNI(s).
