FIBER-LK (Fiber Link)

SNI Off-Board Destructive Facility Test (#756)

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 off-board loop around, while Test 757 returns the

result of the on-board loop around. For SNI-to-SNI fiber links, this test is run on

both SNI circuit pack endpoints of the fiber link.

Description / Recommendation

The system will not allow this test to be run because the fiber link has not been

busied out. Busyout the fiber link with busyout fiber-link F P. Repeat the test

fiber-link F P long command.

Could not allocate the necessary system resources to run this test.
