power connector.
Ready LED

not flashing, it indicates that something is wrong (e.g. another device on the
network at the same IP address).

The Ethernet Speed LED illuminates (green) if the Ethernet connection is
operating at 100Mbit/sec. The LED is off if the connection is operating at
10Mbit/sec.

The Ethernet Link LED illuminates when a connection has been made. It
flashes when there is data traffic on the Ethernet link.
Serial Port LEDs (P1, P2, P3 & P4)
Each serial port has an associated LED. Serial Port LEDs flash (green) when
data is being transmitted or received on the serial ports. When the LED is
illuminated it indicates the serial port is open.
