The Reset Button Details on the Reset button are found on page 7.

The Crossover Switch The Crossover Switch (X II) toggles the LAN port between crossover mode (X) and straight-through mode (II).

If you are connecting the Router’s LAN Port directly to a PC or an uplink port on a hub or switch, choose the crossover (X) mode.

If you are connecting the Router’s LAN port to a standard port on a hub or switch, choose the straight-through (II) mode.

Note: If you’re not sure which mode to use on the Crossover Switch, check the LAN port’s Link LED on the front panel of the Router.

If the Link LED does not light up after the Router is fully installed and config- ured, try switching the Crossover Switch to the other side. If the Link LED lights up, you know that your mode setting is correct.

When“uplinking,” or connecting two pieces of network hardware together, such as a router and a switch, a general rule of thumb is to plug one end of a network cable into a straight-through port, and the other end into a crossover port.

Standard ports are straight-through ports, and uplink ports are crossover ports.

The 1-Port Router’s Front Panel LEDs

BEFSR11 shown above

The LAN Indicators

Power	Green. The Power LED lights up green when the Router is
	powered on.

EtherFast Cable/DSL Routers

Link/Act	Green. The Link/Act LED serves two purposes. If the LED
	is continuously lit up, the Router is successfully connected
	to a device through the LAN port. If the LED is flickering,
	the Router is actively sending or receiving data through the
	LAN port.
Full/Col	Green. The Full/Col LED also serves two purposes. If this
	LED remains lit, a LAN port connection is being success-
	fully maintained. If the LED flickers, the connection is
	experiencing collisions. Infrequent collisions are normal.
	If this LED flickers too often, there may be a problem with
	your connection. See Troubleshooting on page 56 if you
	encounter problems.
10/100	Orange. The 10/100 LED lights up when a successful
	100Mbps connection is made through the corresponding
	port.
	If a connection is running at 10Mbps, the 10/100 LED will
	not light up.

The WAN Indicators

Link	Green. The Link LED lights up when a successful connec-
	tion is made between the Router and your Broadband
	device or network.
Act	Green. The Act LED flickers when the Router is sending or
	receiving data over the broadband WAN port.
Diag	Red. The Diag LED lights up when the Router goes through
	its self-diagnostic test during boot-up. It will turn off upon
	successful completion of the diagnosis. The Diag LED also
	lights up when you press the Reset button or click Apply to
	save any changes made in the Web-based Utility.
	If this LED stays on for an abnormally long period of time,
	see the Troubleshooting section.
