Serial LED.

Ready LED
The Ready LED (green) blinks once per second if the system is operating
correctly. If the LED is off, it indicates the system is not operating correctly (or
that it is in Console Mode).
Ethernet LED
The Ethernet LED illuminates if the Ethernet port is connected and blinks
when data is transmitted or received.
Serial LED
The serial port has an associated LED. The Serial Port LED blinks (green)
when data is being transmitted or received on the serial port. When the LED is
On, it indicates that the serial port is open.
