[. . . ] A collision is occurring on the segment when the port is operating in half-duplex mode. (Note that some collisions are normal. ) Description Power is supplied to the switch. Data is being received or transmitted at 10 Mbps. Vista RJ-45 Network Ports with Built-in LEDs All of the ports on the switch are 10/100 Mbps capable autosensing Ethernet ports. Each port supports only unshielded twisted pair (UTP) cable using an 8pin RJ-45 plug. [. . . ] To install the switch on a wall, measure the distance between the mounting holes on the back of the switch and mark the wall to match the location of the mounting holes on the switch. At the marked location, screw into the wall the two screws that you received with the mounting kit included in your package contents. Be sure to choose a location that is near the devices to be connected, is close to an electrical outlet, and provides at least 2 inches of space all around the switch for ventilation. Model FS308 Fast Ethernet Switch Installation Guide Connect Devices to the Switch Before connecting the switch, be sure you review "Applications" for information about determining the appropriate configuration for your networking needs. Connect the devices to the 10/100 Mbps ports on the switch, using Category 5 UTP cable and an RJ-45 plug. Note: Ethernet specifications limit the cable length between your PC or server and the switch to 328 feet (100 meters) in length. Set the FDX/AUTO toggle switches on the rear panel for the selected duplex mode (the default setting is AUTO). Connect one end of the DC power adapter cable to the power outlet on the rear panel of the switch and the other end of the power adapter cable to the wall outlet. Refer to the following illustration when connecting the Model FS308 switch. Each of the preceding steps has a corresponding reference number in the illustration.

" 8935FA Model FS308 Fast Ethernet Switch Installation Guide Twisted Pair Cables For two devices to communicate, the transmitter of each device must be connected to the receiver of the other device. The crossover function is usually implemented internally as part of the circuitry in the device. Most ports on switches and repeaters have media-dependent interfaces with crossover ports. Computer and workstation adapter cards are usually media-dependent interface ports referred to as MDI or uplink ports. These two figures illustrate the use of straight-through and crossover twisted pair cables. Uplink or MDI port Tx 1 2 Straight-through twisted pair cable Normal or MDI-X port 1 2 Rx Rx 3 6 Crossover twisted pair cable 3 6 Tx Normal or MDI-X port Rx 1 2 Normal or MDI-X port 1 Rx 2 Tx 3 6 3 Tx 6 8146EC RJ-45 Connector The RJ-45 connector (shown in the illustration with an RJ-45 plug) is used to connect workstations, hubs, and switches through unshielded twisted pair cable. The RJ-45 connector accepts four-pair Category 3 or Category 5 UTP cable. Make sure the duplex switch on the Model FS308 Fast Ethernet Switch is set for fullduplex operation. Make sure the connected device is capable of full-duplex transmission. 100 Link/Act LED Port is operating in is off when 10 Mbps mode. 10 Link/Act LED is on and bicolor FDX LED is off when operating in a Fast Ethernet network. Data collision is occurring on the port. The port and switch might be functioning correctly. Data collisions are normal on Ethernet networks and occur when two or more computers transmit data on the network simultaneously. Computers that caused the collision retry transmission at different intervals until the transmission succeeds. Excessive collisions can result when multiple switches are connected and when many computers are connected on the network. [. . . ] This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · Reorient or relocate the receiving antenna. · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
