Ethernet LEDs
The Ethernet connector has two LEDs that indicate speed and activity. When
looking into the connector:
• Activity— The right LED is solid yellow when a link is detected (the cable is
plugged in) and blinks when there is activity.
• Connection Speed—The left LED is green to indicate a 100 Mbps connection
and orange to indicate a 10 Mbps connection. It is off when no cable is
connected.
