FC port status LEDs

On the SAN64B-7 switch, you find 48 LEDs (green/amber) for the first 48 SFP+ ports and 8 tri-color LEDs (green/amber/light-blue) for the last 8 SFP+ ports 48, 50, 52, 54, 56, 60, and 62. The tri-color LEDs pulse once in light-blue, before indicating the FC port status in green or amber. All functions pertaining to the green/amber colors for the last set of 8 LEDs remain the same as the first 48 LEDs.

Use the following table to interpret the FC port status LEDs.

Table 1. FC Port Status LED Patterns during Normal Operation
LED Color	Status of Hardware	Recommended Action
No light	Indicates one of the following: No signal or light carrier (media or cable) detected. The device may be currently initializing. The connected device is configured in an offline state.	Verify that the power LED is on, and check the SFP+ and cable. Verify that the device is not currently being initialized. Verify the status of the connected device.
Steady green	The port is online (connected to an external device) but has no traffic.	No action is required.
Slow-flashing green (on for 1 second; then off for 1 second)	The port is online but is segmented because of a loopback cable or incompatible device connection.	Verify that the correct device is attached to the switch.
Fast-flashing green (on for 1/4 second; then off for 1/4 second)	The port is online, and an internal loopback diagnostic test is running.	No action is required.
Flickering green	The port is online, and frames are flowing through the port.	No action is required.
Steady amber	The port is receiving light or signal carrier, but it is not online yet.	No action is required.
Slow-flashing amber (on for 2 seconds; then off for 2 seconds)	The port is disabled because of diagnostics or the `portDisable` command.	Reset the port. The `portCfgPersistentDisable` command is persistent across reboots.
Fast-flashing amber (on for 1/2 second; then off for 1/2 second)	The SFP+ or port is faulty.	Reset the port. Replace the SFP+. Must be a Brocade-branded SFP+.
