LED patterns

Module Status LED patterns during normal operation and Port link status LED patterns summarize LED color, and meaning, and any recommended user response.

Module status LED patterns

The system and power LED patterns are shown in Module Status LED patterns during normal operation.

Module Status LED patterns during normal operation

LED name	LED color	Status of hardware	Recommended action
Module Status	No light	Switch is off, boot is not complete, or boot failed.	Verify that switch is on and completed booting.
	Steady green	Switch is on and functioning.	No action required.
	Flashing green (on 1 second, off 1 second)	One or both of the following are true: One or more environmental ranges are exceeded. Error log contains one or more port diagnostic error messages.	Check environmental conditions, error log, Port Status LEDs, transceivers, cables, and loopback plugs. Correct error condition. Clear error log. Rerun diagnostics to verify fix.
	Amber	Boot-up state; switch is disabled or offline.	Needs attention.

Port link status LED patterns

Port link status LED patterns shows the LED color, meaning, and recommended action.

Port link status LED patterns

LED name	LED color	Status of hardware	Recommended action
Port Status	No light	Port is offline. No light or signal carrier (transceiver or cable) detected.	Check transceiver and cable.
	Steady green	Port is online (connected to external device) but has no traffic.	No action required.
	Slow-flashing green (on 1 second, off 1 second)	Port is online but segmented, indicating a loopback cable or incompatible switch.	Verify the correct device is connected to port and the switch and port settings are correct.
	Fast-flashing green (on 1/2 second, off 1/2 second)	Port is in internal loopback (diagnostic).	No action required.
	Flickering green	Port is online with traffic flowing through port.	No action required.
	Steady amber	Port is receiving light or signal carrier, but is not yet online.	No action required.
	Slow-flashing amber (on 1 second, off 1 second)	Port is disabled as a result of diagnostics or portDisable command. If the LEDs for all ports are slow-flashing amber, the switch could be disabled.	Enable the port using the portEnable command; If the LEDs for all ports are slow-flashing amber, enable the switch by entering the switchEnable command.
	Fast-flashing amber (on 1/2 second, off 1/2 second)	Port is faulty.	Check the Port Status LEDs, error log, transceiver, and cable or loopback plug. Clear the error log. Rerun the diagnostics to verify the error condition is fixed.
