Instant Broadband™ Series Chapter 2: Getting to Know the 4Port EtherFast® Cable/DSL Router The 4-Port Router's Rear Panel The Router's ports, where network cables are connected, are located on the rear panel of the Router, as shown in Figure 2-1. WAN Ports 1-4 Uplink Power 8 Figure 2-1 The WAN (Wide Area Network) port is where you connect your cable or DSL modem through an Ethernet cable. Your modem connection will not work from any other port. These four LAN (Local Area Network) ports connect to network devices, such as PCs, print servers, and remote hard drives. If Port 1 is being used, the Uplink port will not work because these two shared ports have internally shared wiring. The Uplink port is used to expand your network by connecting to another switch or hub. To uplink to a switch or a hub, simply run a cable from the Uplink port to the other device. See the "Uplinking: Connecting More Devices to the Router" section for more on uplinking. If the Uplink port is being used, Port 1 will not work. The Power port is where you will connect the power adapter. EtherFast® Cable/DSL Routers The 4-Port Router's Front Panel LEDs Power Link/Act Full/Col 100 Figure 2-2 Green. The Power LED lights up when the Router is powered on. Green. The Link/Act LED serves two purposes. If the LED is continuously lit, the Router is successfully connected to a device through the corresponding port (1, 2, 3 or 4). If the LED is flickering, the Router is actively sending or receiving data over that port. Port 1 is lit when using the Uplink port. Green. The Full/Col LED also serves two purposes. If this LED is lit up continuously, the connection made through the corresponding port is running in Full Duplex mode. 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 "Appendix A: Troubleshooting" if you encounter this problem. 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. 9
