SISTF10xx-141-LR(T) Industrial Unmanaged Switch Transition Networks

Light Emitting Diodes (LEDs)

LEDsThe Industrial Switch has LED indicators located on its front panel. The LEDs present at-a- glance network status, and provide real-time connectivity information. Figure 16 shows the LEDs and a chart that explains the function of each.

LED	Description
PWR	Green = input power present on either
	of the power inputs
PWR1	Green = input power present on PWR1
	input
PWR2	Green = input power present on PWR2
	input
LNK/ACT	Green = fiber link
(Fiber port)	Green (blinking) = fiber port is receiving
	link pulses or data from a
	100Base-FX compliant port
FDX/COL	Orange = Full duplex
(Fiber port 5)	Off = Half duplex or no device attached
	Orange (blinking) = Collisions occurring
LNK/ACT	Green = UTP link
(UTP ports 1-4)	Green (blinking) = UTP port is receiving
	link pulses or data from a
	10/100Base-TX compliant port
	Off = No device attached
FDX	Orange = Full duplex
(UTP ports 1-4)	Off = Half duplex or no device attached
	Orange (blinking) = Collisions occurring
