Fibre Channel Ports
Each I/O blade has eight Fibre Channel ports that are interconnected with all other
I/O blades through the backplane. Fibre Channel ports are numbered according to
the slot in which the I/O blade resides. Each port is served by a Small Form-Factor
Pluggable (SFP) transceiver. A Port Status LED, located to the left of each port as
shown in Figure 2-5, provides port login and activity status information. Port
modes configure the ports to communicate with public devices, private devices,
and other switches.
