Symptom Link LED does not light after connection is made. Front-Panel Ports The front-panel ports are dual-speed RJ-45 ports with built-in wiring crossovers. PCs can be connected to these ports with straight-through cable. Each port supports Auto-Negotiation, so the optimum communication mode (half or full duplex) and data rate (10 Mbps or 100 Mbps) are selected automatically. Port 8 on the switch doubles as a crossover port and a straight-through daisy-chain port. The daisy-chain port makes it convenient to connect straight-through cable from the EZ Switch 10/100 to a crossover port on another device. Probable Causes Switch port, network card or cable may be defective. Possible Check that the switch and attached device are both powered on. Be sure the network cable is connected to both devices. Verify that Category 5 cable is used for 100 Mps connections and that the length of any cable does not exceed 100 meters (328 feet). Check the network card and cable connections for defects. Replace the defective card or cable if necessary. Solutions COPYRIGHT Information furnished by SMC Networks, Inc. [. . . ] Each wire pair must be attached to in a specific orientation.
