Connecting the Network Cables
Dual-Homed Station
Dual homing is a double or redundant SAS connection providing a backup link
to an FDDI concentrator on the ring, either the same concentrator or a
different concentrator, so that only one link is active at a time. In the example
configuration shown below, traffic is sent and received over MIC B of the FDDI
Module during normal operation. MIC A is used only if the cable or
concentrator attached to MIC B fails.
