  • Page 18: Switch Architecture

    GSW-1676 BOUT 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.

  • Page 19: Description Of Hardware

    ESCRIPTION OF ARDWARE Description of Hardware 10/100/1000BASE-T Ports The switch contains 16 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.

    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.

    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.
