Checking the connection status of user devices
When EARU 111X is power-fed, the Green and Yellow LEDs should be on.
The green LED is the data indicator. It blinks when data is being transmitted or
received. The Yellow LED is the link indicator. It lights up with a 100Mbps
connection. If there is a 10Mbps connection (a 10BaseT connection), the Yellow
LED is off.
