  • Page 21: Chapter 1: Introduction

    Figure 1-1. Front and Rear Panels Switch Architecture The Matrix V-Series V2H124-24P 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 22: Power-Over-Ethernet Capability

    With a comprehensive array of LEDs, this switch provides “at a glance” monitoring of network and port status. The switch can be managed over the network with a web browser or Telnet application, or via a direct connection to the console port. The switch includes a built-in network management agent that allows it to be managed in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols.

  • Page 23: Description Of Hardware

    Note: The 1000BASE-T RJ-45 ports do not support PoE capability. Port and System Status LEDs The switch base unit also includes a display panel for key system and port indications that simplify installation and network troubleshooting. The LEDs, which are located on the front panel for easy viewing, are shown below and described in the following tables.

  • Page 24: System Status Leds

    Powered device is receiving power. Port has detected a power overload or short circuit and shut down the port’s power. The power budget for the switch has been exceeded and the port's power shut down. No powered device is connected to the port.

  • Page 29: Chapter 2: Network Planning

    Fast Ethernet, the maximum is two; and for Gigabit Ethernet the maximum is one. This is known as the hop count. However, a switch turns the hop count back to zero. So subdividing the network into smaller and more manageable segments, and linking them to the larger network by means of a switch, removes this limitation.

  • Page 30: Application Examples

    Network Planning Application Examples The Matrix V-Series V2H124-24P switch 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 Matrix V-Series V2H124-24P switch is an excellent choice for mixed Ethernet and Fast Ethernet installations in which significant growth is expected in the near future.

  • Page 31: Network Aggregation Plan

    V-Series PoE switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. When up to eight switch units are stacked together, they form a single “virtual” switch containing up to 200 ports. The whole stack can be managed through the Master unit using a single IP address.

  • Page 32: Remote Connections With Fiber Cable

    550 m. A 1000BASE-LX single-mode fiber (SMF) link can run up to 5 km. A 1000BASE-LH single-mode fiber (SMF) link can run up to 70 km. This allows the switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

  • Page 34: Application Notes

    Application Notes 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. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem.

  • Page 35: Chapter 3: Installing The Switch

    Chapter 3: Installing the Switch Selecting a Site Matrix V-Series V2H124-24P units can be mounted in a standard 19-inch equipment rack or on a flat surface.

  • Page 46: Cabling Guidelines

    Figure 4-1. Making Twisted-Pair Connections If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet. (See the section “Network Wiring Connections.”) Otherwise, attach the other end to an available port on the switch.

  • Page 47: Network Wiring Connections

    Instructions for making connections in the wiring closet with this type of equipment follow. Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel.

  • Page 48: Fiber Optic Devices

    Connect one end of the cable to the LC port on the switch and the other end to the port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation.

  • Page 49: Connectivity Rules

    However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.

  • Page 50: 100 Mbps Fast Ethernet Collision Domain

    For each piece of equipment, identify the devices to which it is connected. • Note the length of each cable and the maximum cable length supported by the switch ports. • For ease of understanding, use a location-based key when assigning prefixes to your cable labeling.

  • Page 51: Appendix A: Troubleshooting

    • Internal power supply may be disconnected. Check connections between the switch, the power cord and the wall outlet. • The system has detected a fault. Power cycle the switch to try and clear the condition. • If the condition does not clear, contact your dealer for assistance.

    IP address. Also, be sure the port through which you are connecting to the switch has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the switch.

  • Page 53: Appendix B: Cables

    In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable. When using any RJ-45 port on this switch, you can use either straight-through or crossover cable.

  • Page 54: 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 this switch, you can use either straight-through or crossover cable to connect to any device type.)

  • Page 55: 1000Base-T Pin Assignments

    End A 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.
