User manual TRENDNET TE100-S88FX

[. . . ] Expensive routing equipment was used in the past to reduce the congestion under heavy loads. The new wave of object-oriented client and server applications demands higher bandwidth and tighter integration of client work stations with servers. The old shared-access Ethernet technology provides neither enough bandwidth nor predictable response time for this new wave of workgroup computing. Fast Ethernet switching not only satisfies both technical and business requirements, but also preserves the user's existing investment in the huge 10BASE-T Ethernet installed base. [. . . ] A 10BASE-T network may range up to 100 meters with Category 3, 4, or 5 STP/UTP cable. As for the length of FX fiber link between a switch and Data Terminal Equipment, FX is capable to span at least 2 Kilometers using 62. 5/125-micron fiber-optic cable in full-duplex mode and 412 meters in half-duplex mode. The following table summarizes the port and cable specifications for this switch.

Figure 2: LED & Button Indicators Port Status 10/100BASE-TX Ports Each port has an array of three LEDs to show status information. The LEDs are identified by a corresponding array of captions located below the LEDs on the front panel. LNK/ACT: The link indicator is the top LED. It is illuminated whenever the port is connected to another working networked device. The LED flashes when the port is transmitting or receiving data. 100: The middle LED comes on whenever the switch detects that the corresponding port is connected to a 100BASE-TX segment. 10 FastEthernetSwitch User'sGuide FastEthernet Switch FDX/COL: The lower LED is illuminated when the port is operating in full-duplex mode. When this LED is off, the port is operating in half-duplex mode. The LED flashes when the switch detects packet collisions on the port. Power This LED comes on when the switch is connected to a power supply and turned on. Auto MDIX If connecting to an uplink port of a hub or another switch, any of the switch's RJ-45 ports can be used. FastEthernetSwitch User'sGuide 11 Fast Ethernet Switch Port Status 100BASE-FX Ports Each port has an array of three LEDs to show status information. The LEDs are identified by a corresponding array of captions located beside the LEDs on the front panel. LNK/ACT: The link indicator is the top LED. It is illuminated whenever the port is connected to another working networked device. The LED flashes when the port is transmitting or receiving data. 100: The middle LED shines whenever the switch detects that the corresponding port is connected to a 100BASE (100Mbps) segment. FDX/COL: The lower LED is illuminated when the port is operating in full-duplex mode. When this LED is off, the port is operating in half-duplex mode. The LED flashes when the switch detects packet collisions on the port. Power This LED comes on when the switch is connected to a power supply and turned on. Activity Status TX: Transmit Data RX: Receive Data 12 FastEthernetSwitch User'sGuide FastEthernet Switch Dip Switch Full-Duplex: Toggle up to enable Full-Duplex mode for 100BASE-FX ports (Default setting). Half-Duplex: Toggle down to enable Half-Duplex mode for 100BASE-FX ports. There is no auto MDIX for fiber 100BASE-FX ports; thus the auto MDIX status does not apply to 100BASE-FX ports. FastEthernetSwitch User'sGuide 13 Fast Ethernet Switch Installation This chapter presents step-by-step installation instructions for this eight-port Ethernet Switch. Selecting a Site for the Switch As with any electronic device, you should place the Switch where it will not be subjected to extreme temperatures, humidity, or electromagnetic interference. Specifically, the site you select should meet the following requirements: The room temperature should be between 32 and 104 degrees Fahrenheit (0 to 40 degrees Celsius). The relative humidity should be less than 90 percent, non-condensing. Surrounding electrical devices should not exceed the electromagnetic field (RFC) standards for IEC 801-3, Level 2 (3V/M) field strength. Make sure that the switch receives adequate ventilation. [. . . ] Hub, also called repeater, only allows users to share Ethernet. Individuals of a shared network can only get a percentage of the available network bandwidth, therefore, a network of repeaters also named "Shared Ethernet". FastEthernetSwitch User'sGuide 21 Fast Ethernet Switch Switches The function of a switch is to connect separate networks together. A Switch maps the Ethernet addresses of the nodes residing on each network segment and then allows only the necessary traffic to pass through. When a packet is received by the switch, the switch determines the destination and source segments of a packet and forward it to the right direction or drop it if the destination and the source are originated from the same network.
