Chapter 1: Introduction Overview The Matrix V-Series V2H124-24P switch contains 24 10BASE-T/100BASE-TX RJ-45 ports and two combination ports—10/100/1000BASE-T ports that operate in combination with Small Form Factor Pluggable (SFP) transceiver slots. An optional SFP stacking transceiver is available for connecting up to eight units to a 1 Gbps stack backplane. All the 10BASE-T/100BASE-TX ports on this switch support IEEE 802.3af draft standard (802.3af) Power-over-Ethernet capabilities.
1 Introduction This switch includes two Gigabit combination ports with RJ-45 connectors and associated SFP slots. The optional SFP stacking transceiver enables up to eight units to be connected together through a 1 Gbps stack backplane. The switch stack can be managed from a master unit using a single IP address. Power-over-Ethernet Capability The switch’s 24 10/100 Mbps ports support the IEEE 802.
1 Description of Hardware Description of Hardware 10/100BASE-T Ports The PoE switch base unit contains 24 10BASE-T/100BASE-TX RJ-45 ports. All 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. (See "10/100BASE-TX Pin Assignments" on page B-1.
1 Introduction The port status LEDs have two display modes: Link and PoE. The Link mode displays the link status and network activity on each port. The PoE mode displays the PoE power status on each port. Use the Mode Link/PoE button (see "Mode PoE/ Link Button" on page 1-6) on the front panel to toggle between the two display modes. The current mode is indicated by the Link/Act and PoE system LEDs. Table 1-1.

1 Introduction Features and Benefits Connectivity • 24 dual-speed ports for easy Fast Ethernet integration and for protection of your investment in legacy LAN equipment • All 10/100 RJ-45 ports support IEEE 802.
Chapter 2: Network Planning 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. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology.
2 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.
2 Application Examples Network Aggregation Plan With 24 parallel bridging ports (i.e., 24 distinct collision domains), the Matrix 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.
2 Network Planning Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. Using a 1000BASE-SX multimode fiber (MMF) SFP transceiver, you can run a link up to 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.
2 Application Examples Making VLAN Connections This switch supports VLANs which 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. VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs.
2 Network Planning 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. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub. 3.
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.
3 Installing the Switch RJ-45 Connector 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.
Mounting 3 Optional Rack-Mounting Equipment If you plan to rack-mount the switch, be sure to have the following equipment available: • Four mounting screws for each device you plan to install in a rack—these are not included • 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.
3 Installing the Switch 2. Mount the device in the rack, using four rack-mounting screws (not provided). 25 26 Link/A ct PW R PoE Diag V2H 25 26 124 -24 Stac king P Mo PoE/de Link Figure 3-3. Installing the Switch in a Rack 3. If installing a single switch only, turn to “Connecting to a Power Source” at the end of this chapter. 4. If installing multiple switches, mount them in the rack, one below the other, in any order.
3 Installing an SFP Transceiver 2. 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. 3. If installing a single switch only, go to “Connecting to a Power Source” at the end of this chapter. 4. If installing multiple switches, attach four adhesive feet to each one. Place each device squarely on top of the one below, in any order.
3 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. Figure 3-7 shows how stacking cables are connected between switches in a stack. Note: The stacking transceiver must only be installed in the port 25 SFP slot.

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. If 802.3af-compliant PoE devices are connected to the switch’s 10/100 Mbps ports, the switch automatically supplies the required power.
4 Making Network Connections Cabling Guidelines The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs). See Appendix B for further information on cabling. Caution: Do not plug a normal phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with RJ-45 connectors that conform to FCC standards.
Twisted-Pair Devices 4 Network Wiring Connections Today, the punch-down block is an integral part of many newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follow. 1. Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel. 2.
4 Making Network Connections Fiber Optic Devices An optional slide-in 1000BASE-SX, 1000BASE-LX, or 1000BASE-LH SFP transceiver may be used for backbone or remote connections, or for connecting to a high-speed server. Each single-mode fiber optic port requires 9/125 micron single-mode fiber optic cabling with an LC connector at both ends. Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends.
Connectivity Rules 4 Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed in the manuals for these products. 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.

A Troubleshooting Installation Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly. In-Band Access You can access the management agent in the switch from anywhere within the attached network using Telnet, a web browser, or other network management software tools.
Appendix B: Cables Twisted-Pair Cable and Pin Assignments Caution: DO NOT plug a normal phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards. For 10/100BASE-TX connections, the 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.
