System LEDs	Indication
Fault	• When lit, one or more of the ports has failed or the internal temperature has
(yellow LED)	exceeded acceptable levels.
	• When flashing, all ports are operational but another error has occurred. Errors
	appear in an event log. The level of error severity that will cause flashing to start
	can be controlled using the config sys fault command in the CLI. The default is
	level 3, Critical.
	Note: Whether lit or flashing, the switch will continue to operate. Switch
	functionality may be impaired depending on the event that triggered the
	Fault LED. Regardless of the cause, the switch requires immediate
	attention.
Power	When lit, the switch is plugged in and the internal power supply is functional.
(green LED)
2 Gb/s	When lit, the switch is set to operate at a speed of 2 Gb/s. When off, the switch is
(green LED)	set to 1 Gb/s.
Switch	• When lit, indicates that the switch has completed initialization for ports with
Operational	inserted SFPs and that the switch is operational.
(green LED)	• When flashing, the switch has been configured for multiple zones, and one or
	more zones are up with at least one zone down.
	If no zones (excluding hard zones) are operational, the LED turns off.
