The next table lists the failure rate calculation (FIT) and the MTBF (Mean Time
Between Failures) of the different option cards (calculated according to RIN8.0 with
confidence level of 60 %). Note that the failure rates of packs in this document may
differ from rates of similar packs in previous documents. This is due to differences in
parameters that match design specifications and applications such as electrical stress
level.
