Fibre Channel Port LEDs

Fibre Channel Port LEDs are adjacent to each Fibre Channel port. They indicate port status and activity. Each port has a one bi-color, green/yellow, LED to indicate port status. When you enable a Fibre Channel interface module, and a Fibre Channel device is already connected, the run light (LED) of the Fibre Channel interface port changes from yellow to green, indicating that a connection has been established between the Fibre Channel device and the port.

Table 5-12explains the Fibre Channel port status LED.

LED State		Indication
Off		Optic module or cable is not attached.
Solid yellow		A cable is attached, but the port is offline.
