  • Page 24: About The Ez Switch 10/100/1000

    EZ S 10/100/1000 BOUT THE WITCH Switch Architecture The switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. The switch uses store-and-forward switching to ensure maximum data integrity.

  • Page 25: Description Of Hardware

    ESCRIPTION OF ARDWARE Description of Hardware 10/100/1000BASE-T Ports The switch contains 24 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. Because all ports on the switch support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.

  • Page 29: Network Planning

    HAPTER ETWORK LANNING Introduction to Switching A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. Switches have, therefore, been recognized as one of the most important building blocks for today’s networking technology.

  • Page 30: Application Examples

    ETWORK LANNING Application Examples The EZ Switch 10/100/1000 is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below. Collapsed Backbone The EZ Switch 10/100/1000 is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future.

  • Page 31: Central Wiring Closet

    PPLICATION XAMPLES Central Wiring Closet With 24 parallel bridging ports (i.e., 24 distinct collision domains), this switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 1000BASE-T RJ-45 ports on the switch are providing 1 Gbps full-duplex connections for up to 24 local segments.

  • Page 32: Remote Connections With Fiber Cable

    ETWORK LANNING Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-ZX link up to 100 km.

  • Page 33: Making Vlan Connections

    PPLICATION XAMPLES Making VLAN Connections The switch supports VLANs that can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment.

  • Page 34: Application Notes

    ETWORK LANNING Application Notes 1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. 2.

    PPENDIX ABLES Twisted-Pair Cable and Pin Assignments For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes.

    ABLES 10BASE-T/100BASE-TX Pin Assignments Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).

  • Page 97: Straight-Through Wiring

    WISTED ABLE AND SSIGNMENTS Straight-Through Wiring If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through. (When auto-negotiation is enabled for any RJ-45 port on the switch, you can use either straight-through or crossover cable to connect to any device type.) You must connect all four wire pairs as shown in the following diagram to...

  • Page 98: Crossover Wiring

    ABLES Crossover Wiring If the twisted-pair cable is to join two ports and either both ports are labeled with an “X” (indicating MDI-X) or neither port is labeled with an “X” (which indicates MDI), a crossover must be implemented in the wiring.

    WISTED ABLE AND SSIGNMENTS 1000BASE-T Pin Assignments All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports require that all four pairs of wires be connected.

    ABLES Note that when testing your cable installation, be sure to include all patch cables between switches and end devices. Adjusting Existing Category 5 Cabling to Run 1000BASE-T If your existing Category 5 installation does not meet one of the test parameters for 1000BASE-T, there are basically three measures that can be applied to try and correct the problem: 1.
