Full/Col Green. The Full/Col LED also serves two purposes. If this LED
is lit up solidly, the connection made through the corresponding
port is running in Full Duplex mode. If the LED flickers, the
connection is experiencing collisions (when two PCs send data
at the same time). Infrequent collisions are normal.
If this LED flickers continuously, there may be a problem with
your connection. See "Appendix A: Troubleshooting" if you
encounter this problem.
100 Orange. The 100 LED lights up when a successful 100Mbps
connection is made through the corresponding port.
If this LED does not light up, then your connection speed is 10
Mbps.
The WAN Indicators
Link Green. The Link LED lights up when a successful connection is

receiving data over the WAN port.

self-diagnosis mode during every boot-up. It will turn off upon
successful completion of the diagnosis.

Chapter 3: Connect the Router

Overview

Unlike a hub or a switch, the Router's setup consists of more than simply plug-
ging hardware together. You will have to configure your networked PCs to
accept the IP addresses that the Router assigns them (if applicable), and you
will also have to configure the Router with setting(s) provided by your Internet
Service Provider (ISP).
An example of this setup is shown in Figure 3-1.
The installation technician from your ISP should have left the setup informa-
tion for your modem with you after installing your broadband connection. If
not, you can call your ISP to request the data.
Once you have the setup information you need for your specific type of Internet
connection, you can begin installation and setup of the Router.
