For EI-EI fibers that connect an EPN to the PPN, the EI on the EPN is reset first
followed by the EI on the PPN. For EI-EI fiber links that connect two EPN s, one EI
is reset first followed by the other.
For an EI-SNI fiber link in which the EI is on the PPN, the SNI is reset first followed
by the EI.
For an EI-SNI fiber link in which the EI is on an EPN, the SNI is reset first followed
by the EI.
For an SNI-SNI fiber link, the SNI farthest from the PPN is reset first followed by
the SNI nearest to the PPN.
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 t ests a re de scri bed in the EXP- INTF and SNI-B D sec tions .
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 indic ation of how the
other reset tests are running, use the reset board UUCSS c ommand on each
individual fiber link endpoint.
Failure Audit (#777)
This test is non-destructive.
This test queries the SNI (s) on the fiber link for any existing failures and any
unacknowledged cleared failure messages. Each failure g enerates an error and
alarm entry against SNI-BD, SNI-PEER, or FIBER-LK. An unacknowledg ed
cleared failure message is a messag e the SNI circuit pack sent to software
indicating a p revious failure is now gone and the SNI circuit p ack did not recei ve

Error
Code Test
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 a maximum of 3 times.
PASS The reset of both fiber endpoints successfully completed.
