	Figure 3-2: The Router’s LEDs
POWER	Green. The POWER LED lights up and will stay on while the Router is powered on. When the
	Router goes through its self-diagnostic mode during every boot-up, this LED will flash. When
	the diagnostic is complete, the LED will be solidly lit.
ETHERNET
1, 2, 3, 4	Green. These numbered LEDs, corresponding with the numbered ports on the Router’s back
	panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected
	to a device through that port. If the LED is flashing, that port is actively transmitting or
	receiving data.
WIRELESS	Green. The WIRELESS LED lights up whenever there is a successful wireless connection. If the
	LED is flashing, the Router is actively sending or receiving data over the wireless network.
DMZ	Green. The DMZ LED indicates when the DMZ function is being used. This LED will remain lit
	as long as DMZ is enabled.
INTERNET	Green. The INTERNET LED lights up when there is a connection made through the Internet
	port. If the LED is flashing, that port is actively transmitting or receiving data.
