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.

This indicator is green when the respective port is properly connected to
a powered-on device and blinks green when packets are being

this LED will not light to indicate the connection, but it will blink to
indicate packet transmission and reception.
