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.
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.
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.
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.
System diagnostic test has detected a fault. Cannot receive packet from stacking port. This switch is acting as the master unit in the stack. Initial state of stacking configuration to determin whether the switch will act as a master or slave unit.
The unit also includes a Stack Master button that is shown in the following diagram. Stack Master Button Figure 1-4. Stack Master Button The Stack Master button enables one switch in the stack to be selected as the master. Mode PoE/Link Button The Mode PoE/Link button is located on the front panel.
(One stacking cable is included with each optional stacking transceiver.) The push button on the switch’s front panel (see "Stack Master Button" on page 1-6) enables one switch in the stack to be selected as the master.

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.
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.
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.
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.

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.
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. 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.
Installing the Switch Figure 3-1. RJ-45 Connections Equipment Checklist After unpacking this switch, check the contents to be that sure you have received all the components. Then, before beginning the installation, be sure that you have all other necessary installation equipment.
• A screwdriver (Phillips or flathead, depending on the type of screws used) 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. Rack Mounting Before rack mounting the switch, pay particular attention to the following factors: •...
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.
Set the device on a flat surface near an AC power source, making sure there are at least two inches of space on all sides for proper air flow. If installing a single switch only, go to “Connecting to a Power Source” at the end of this chapter.
Installing the Switch Stacking Switches The switch supports stacking up to eight units through an optional SFP stacking transceiver. The stacking transceiver must be installed in the port 25 slot. Each stacking transceiver has two connectors, Tx and Rx, for attaching stacking cables.
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.
LED is lit. If not, check that the power cable is correctly plugged in. Connecting to the Console Port The DB-9 serial port on the switch’s front panel is used to connect to the switch for out-of-band console configuration. The command-line configuration program can be accessed from a terminal or a PC running a terminal emulation program.

Chapter 4: Making Network Connections Connecting Network Devices The Matix V-Series V2H124-24P switch is designed to be connected to 10 or 100 Mbps network cards in PCs and servers, as well as to other switches and hubs. It may also be connected to remote devices using the optional 1000BASE-SFP transceivers.
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.
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.
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.
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.
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.
• 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.
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.
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.)
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.
Cables Cable Testing for Existing Category 5 Cable Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in the ANSI/TIA/EIA-TSB-67 standard. Cables must also pass test parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT).
