FC Port Status LEDs
During runtime operation, each Fibre Channel port's LED indicates real-time status for
the port.
-
Green link or activity (LNK/ACT) LED indicates physical and logical-layer
connectivity and the presence of FC frames on the link.
-
Green speed (SPD) LED indicates the data rate of traffic on the link, 4 Gbps,
8 Gbps, or 16 Gbps.
Each port's SPD and LNK/ACT LEDs
work together to indicate the port's current status.
