First and second inputs are associated with a port. Logic produces
indications to software to cause the first input and second input to
appear as a single input to the software. The logic produces an
indication that no signal is present on either the first input or the
second input. When a port bypass controller is coupled to the port, the
logic produces an indication that both the first and second inputs are
bypassed. When the port bypass controller is coupled to a Fibre Channel
arbitrated loop, the logic produces a first signal to control whether the
first input is included on the Fibre Channel arbitrated loop or bypassed,
and a second signal to control whether the second input is included in
the Fibre Channel arbitrated loop or bypassed.
