This indicator is green when power is supplied to the device. The Power
LED lights when you connect the power cable to the power receptacle at
the rear of the device, and then plug it in to a power outlet.
•
Link/Act LED
This indicator is green when the respective port is properly connected to
a powered-on device and blinks green when packets are being
transmitted or received. If the AUI or BNC connector of port 1 is used,
this LED will not light to indicate the connection, but it will blink to
indicate packet transmission and reception.
