1.6.2 Perform a Terminal Loopback on a Source-Node FC_MR Port
The terminal loopback test is performed on the node source FC_MR muxponder or transponder port. For
the circuit in this example, the test port is the source FC_MR port in the source node. Completing a
successful terminal loopback to a node source port verifies that the circuit is good to the source port.
