DIAGNOSTIC LED(S)
LED	Color	Status	Condition
L1	Yellow	Blinking	Data is being transmitted or received
L1	Yellow	Off	Data is not being transmitted or received
L2	Green	On	Twisted pair network connection is good
L2	Green	Blinking	Twisted pair wire polarity reversed
L2	Green	Off	Twisted pair network connection is broken
Note: Reversed polarity is automatically corrected for but this may impede performance. It is suggested that reversed polarity wires be corrected to attain maximum performance.
