The Crossover Switch

When“uplinking,” or connecting two pieces of network hardware together, such as a hub 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

The LAN Indicators

Power	Green. The Power LED lights up green when the Router is
	powered on.
Link/Act	Green. The Link/Act LED serves two purposes. If the LED

EtherFast® Cable/DSL Routers

is continuously lit, 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 successful- ly maintained. If the LED flickers, the connection is experi- encing collisions. Infrequent collisions are normal.

If this LED flickers too often, there may be a problem with your connection. See the Troubleshooting section if you encounter this problem.

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 mode. It will turn off upon successful
	completion of the diagnosis.
	If this LED stays on for an abnormally long period of time,
	see the Troubleshooting section.
