Fiber Type Optical Maximum Cable Length Wavelength Multimode 1300 nm 2 km (1.24 miles) See “Cable Specifications” on page 30 for further information. Note: As a general rule, the length of fiber optic cable for a single switched link should not exceed 2 kilometers (1.24 miles) for multimode fiber.
  • Page 24 NSTALLING THE WITCH 6. Connecting to a 1000BASE-T Port: The 1000BASE-T module operates at 1000, 100 and 10 Mbps and supports IEEE 802.3x flow control. Auto-negotiation is used to select the optimal transmission speed and communication mode for each connection. Use Category 5 or 5e cable of maximum length 100m (328 feet).

  • Page 25: Sample Application

    NSTALLING THE WITCH Sample Application In the figure below, the EZ Switch 10/100 is operating as a collapsed backbone for a small LAN. It is providing dedicated 20 Mbps full-duplex connections to workstations and 200 Mbps full-duplex connections to power users and servers. An optional Gigabit fiber module installed in the front panel is used to provide a 2 Gbps full-duplex link to a switch up to 550 m away.

  • Page 26: Configuring The Switch From The Console Port

    ROM THE ONSOLE Configuration The SMC-EZ1026DT can be configured, via a console cable, from a PC using Windows 95, Windows 98 or Windows NT 4.0. First, connect a PC to the switch using an RS232 null-modem cable. Then install and run the utility program to configure the switch.

  • Page 27: Program Description

    ONFIGURING THE WITCH ROM THE ONSOLE Program Description Main Window From this window you can read the current configuration of the switch, set a new configuration and write this configuration into the device. The parts of the main window are summarized as follows: Device Type Select the device type that you wish to configure.
  • Page 28 ONFIGURING THE WITCH ROM THE ONSOLE RS232 COM Port Select the console port to connect to the switch. File: Open Browse for an existing configuration file and open it to configure the switch. File: Save Save the current configuration to a switch configuration file. Properties This opens up the three-page properties window from which new configuration settings may be entered.

  • Page 29: Properties Window

    ONFIGURING THE WITCH ROM THE ONSOLE Properties Window Port Page Use this page to configure the parameters of the ports. Click on a radio button in the “Port Selection” section to select the port to be configured and then select the properties from the configuration section.
  • Page 30 ONFIGURING THE WITCH ROM THE ONSOLE Full-Duplex Flow Control (802.3X) This eliminates frame loss by “blocking” traffic from end stations or segments connected directly to the switch. IEEE 802.3x Flow Control is used for full duplex. Auto-Negotiation Auto-negotiation for data rate and duplex mode may be enabled. If auto-negotiation is disabled, data rate and duplex mode must be specified.

  • Page 31: Trunk Assignment

    ONFIGURING THE WITCH ROM THE ONSOLE Trunk Assignment On this page you can configure port trunks. Ports can be combined into an aggregate link to increase the bandwidth of a network connection or ensure fault recovery. You can group ports into trunks that consist of two to eight ports.
  • Page 32 ONFIGURING THE WITCH ROM THE ONSOLE • All the ports in a trunk have to be treated as a whole when moved from/to, added or deleted from a VLAN. • Configure the trunk prior to connecting any cable between the switches to avoid creating a loop.
  • Page 33 ONFIGURING THE WITCH ROM THE ONSOLE Load Balancing Method: Port Based The port-based load-balancing method is an explicit port assignment scheme. Each port that does not belong to a particular trunk must be assigned to a port in that trunk. When the switch receives a packet with a DA that is associated with a trunk , it will automatically forward the packet to the trunk port that the receiving port has been assigned to.
  • Page 34 ONFIGURING THE WITCH ROM THE ONSOLE After selecting a trunk, click the “Port Based” button under “Load Balancing Mapping” to invoke the dialog box “Port Balanced Trunk Port Mapping for Trunk X.” Then click the radio buttons to configure the port-based load-balancing mapping, as shown below.
  • Page 35 ONFIGURING THE WITCH ROM THE ONSOLE VLAN On this page you can configure the membership of VLAN groups. A VLAN group is basically a broadcast domain, but ports and trunks may belong to more than one VLAN group. Any individual trunk or port can be a member of a VLAN group.
  • Page 36 ONFIGURING THE WITCH ROM THE ONSOLE Click on the “Add” button to invoke the dialog box “Add a new VLAN Group.” click on the “Trunk” and “Individual Port” checkboxes to configure the VLAN group, then click “OK.” Note: Once a VLAN group has been added, all other unselected ports will be gathered into one implicit VLAN group.

Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive. Use 100-ohm Category 5 or 5e unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for 1000BASE-T connections.

    ABLES 1000BASE-T Cable Requirements All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) cable should be used.
