Fiber Link Reset Test (#768)
This test is destructive.
This test resets both endpoints of the fiber link and is executed via the reset
fiber-link F P command. Any DS1 CONV circuit packs on the fiber link are not
reset. The reset fiber-link command should almost never be used. It may be
necessary to use it when the endpoint circuit packs enter a mode in which they
cannot communicate with software. When necessary, always reset fiber
endpoints with the command instead of reseating the endpoint circuit packs.
For EI-to-EI fibers that connect an IPSI PN, the EI on the PN is reset first followed
by the EI on the IPSI PN. For EI-to-EI fiber links that connect two PNs, one EI is
reset first followed by the other.
For an EI-SNI fiber link in which the EI is on the PN, the SNI is reset first followed
by the EI.
For an EI-SNI fiber link in which the EI is on an PN, the SNI is reset first followed
by the EI.
For an SNI-to-SNI fiber link, the SNI farthest from the PN is reset first followed by
the SNI nearest to the PN.
When an EI endpoint is reset, the Expansion Interface Reset test (#336) is
executed. When an SNI endpoint is reset, the SNI Reset test (#761) is executed.
These tests are described in the EXP-INTF and SNI-BD sections.
This test starts the other reset test mentioned above and returns PASS without
waiting for the results of the other reset test. For a better indication of how the
other reset tests are running, use the reset board UUCSS command on each
individual fiber link endpoint.

Error Test
Code Result Description / Recommendation
1703 ABORT Both fiber endpoints are in the hardware path for INLs to their respective switch
node carriers and, thus, cannot get a response from this test because the INLs
response should come on will go down as a result of the reset.
1. Reset the individual fiber-link endpoints via the reset board command.
2500 ABORT Internal system error
1. Retry the command at 1-minute intervals up to 3 times.
PASS The reset of both fiber endpoints successfully completed.
