2 – General Description Fibre Channel Ports

S

Each port is served by a small form-factor pluggable (SFP) optical transceiver and is capable of 1-Gbps or 2-Gbps transmission. SFPs are hot-pluggable. FC ports can self-discover both the connection type and transmission speed when connected to public devices or switches. The port LEDs are located to the right of their respective ports and provide status and activity information.

Fibre Channel Port LEDs

Each port has three LEDs:

„The amber LED (top) shows activity (data is passing through the port).

„The green LED (middle) shows the logged-in or initialization status of the connected devices. This LED flashes off to show the link rate, once for 1-Gbps speed, and twice for 2-Gbps speed.

„The yellow (bottom) LED shows an alert (port fault) condition.

Table 2-2describes the LED blink patterns and their meanings.
