		temperature range of 0 ºC to 50 ºC (32 ºF to 122 ºF), with
		adequate airflow around the router and its vents.
PIC0	Green	A port interface card (PIC) is correctly installed and has
PIC1		been detected by the router.
ETH0 / ETH1	Green	The Eth port has a 100 Mbps link.
L/A
	Amber	The Eth port has a 10 Mbps link.
	Flashing	Data is being transmitted on the Eth port.
ETH0 / ETH1	Green	The Eth port is operating at full duplex.
