Failure Conditions, Fail-safe, and Fail-through

During any failure condition of the 7110/7115, unprocessed data packets can either pass through or not, depending on whether Fail- safe or Fail-through mode is enabled. The Fail-through switch is by default in Fail-safe mode, meaning that during a failure no data packets will pass from one side of the 7110/7115 to the other. For details, see “Failure/Bypass Modes” in Appendix B.
