  • Page 23: Chapter 1: Introduction

    Chapter 1: Introduction Overview The Matrix V-Series V2H124-24 switch is a stackable Fast Ethernet switch with 24 10BASE-T / 100BASE-TX ports and two ports for 100BASE-FX, 1000BASE-T, or combination 1000BASE-T/SFP uplink modules, or a stacking module. The V2H124-24 also includes an SNMP-based management agent, which provides both in-band and out-of-band access for managing the switch.

  • Page 24: Network Management Options

    With a comprehensive arrange of LEDs, the V2H124-24 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.

  • Page 25: Port And System Status Leds

    Port and System Status LEDs The V2H124-24 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 26: Power Supply Receptacles

    (Link/Activity) On/Flashing Green Power Supply Receptacles There are two power receptacles on the rear panel of the switch. The standard power receptacle is for the AC power cord. The receptacle labeled “RPU” is for the optional Redundant Power Unit (RPU).

Single-Port 100BASE-FX Multimode Module Using multimode fiber optic cable, the 100BASE-FX port can be connected to a remote site up to 2 km (1.24 miles) away. The 100BASE-FX module is fixed to operate at 100 Mbps full duplex, and supports auto-negotiation for flow control.

  • Page 31: 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 32: Application Examples

    When the time comes for further expansion, just connect to another hub or switch using one of the Fast Ethernet ports built into the front panel or a Gigabit Ethernet port on a slide-in expansion module.

  • Page 33: Network Aggregation Plan

    In the figure below, the 10BASE-T/100BASE-TX ports on the switch are providing 100 Mbps connectivity for up to 24 segments. In addition, the switch is also connecting several servers at 1000 Mbps. Server Farm 10/100 Mbps Segments Figure 2-2.

    100BASE-FX multimode fiber (MMF) slide-in module, you can run a link up to 2 km. A 100BASE-FX single-mode fiber (SMF) link can run up to 20 km. This allows the switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

  • Page 36: 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 37: Chapter 3: Installing The Switch

    Chapter 3: Installing the Switch Selecting a Site Switch units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location. • The site should: • be at the center of all the devices you want to link and near a power outlet.

    Mounting This switch can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting instructions for each type of site follow. Installing Optional Modules: Before mounting the switch, you may want to install optional modules. If you have purchased optional slide-in 100BASE-FX, 1000BASE-T, 1000BASE-T/SFP, or stacking modules, install these modules now, following the instructions “Installing an Optional Module into the Switch”...

  • Page 40: Desktop Or Shelf Mounting

    Mount the device in the rack, using four rack-mounting screws (not provided). Figure 3-3. Installing the Switch in a Rack If installing a single switch only, turn to “Connecting to a Power Source” at the end of this chapter. If installing multiple switches, mount them in the rack, one below the other, in any order.

  • Page 41: Installing An Optional Module Into The Switch

    Remove the blank metal plate (or a previously installed module) from the appropriate port by removing the two screws with a flat-head screwdriver. With the module still in the anti-static bag, touch the metal frame of the switch to prevent damage caused by static electricity discharge. Also, it is recommended to use an ESD wrist strap during installation.

  • Page 42: Installing An Sfp Transceiver

    Slide the SFP transceiver into the port until it clicks into place. Note: SFP transceivers are hot-swappable. The switch does not need to be powered off before installing or removing a transceiver. However, always first disconnect the network cable before removing a transceiver.

  • Page 43: Figure 3-7. Connecting Switches In A Stack

    Only one switch in the stack can operate as the Master, all other units operate in slave mode. If more than one switch in the stack is selected as Master, or if no switches are selected, the stack will not function.

    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.

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

    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.

    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 58: 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.)

    EIA/TIA 568B RJ-45 Wiring Standard 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.
