Chapter 1: Introduction Overview The Matrix V-Series V2H124-24FX switch is a stackable Fast Ethernet switch with 24 100BASE-FX multimode MT-RJ ports and two slots for 100BASE-FX, 1000BASE-T, or combination 1000BASE-T/SFP uplink modules, or a stacking module. The V2H124-24FX also includes an SNMP-based management agent, which provides both in-band and out-of-band access for managing the switch.
With a comprehensive array of LEDs, the V2H124-24FX 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.
Port and System Status LEDs The V2H124-24FX 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.
Introduction Condition 25~26 On/Flashing Green Port has established a valid 1000 Mbps network connection. (Link/Activity) On/Flashing Amber Amber and Green Alternate Table 1-2. Module LEDs Status Flashing indicates activity. Port has established a valid 10/100 Mbps network connection. Flashing indicates activity. The port has been administratively disabled.
Amber 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).
Introduction Optional Media Extender Modules 100BASE-FX Multimode Module 100BASE-FX Multimode Module Figure 1-5. 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.
Using Category 5, 5e, or 6 twisted-pair cable you can connect to another device up to 100 m (328 ft) away. The 1000BASE-T module operates at 10, 100, and 1000 Mbps. At 1000 Mbps it operates at full duplex and supports auto-negotiation of speed and flow control.
The module allows up to eight switches to be linked together using stacking cables. The push button on the module enables one switch in the stack to be selected as the master. Features and Benefits Connectivity •...
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.
100 Mbps fiber connections to workstations and servers. When the time comes for further expansion, just connect to another switch using one of the Fast Ethernet ports built into the front panel or a Gigabit Ethernet port on a slide-in expansion module.
The 100BASE-FX multimode fiber (MT-RJ) ports enable you to run links of up to 2 km. This allows the switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.
100BASE-FX multimode fiber (MMF) slide-in module, you can run additional links of 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.
Testing VLAN 3 VLAN 4 Figure 2-4. Making VLAN Connections Note: When connecting to a switch that does not support IEEE 802.1Q VLAN tags, use untagged ports. 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).
Page 38
Network Planning As a general rule the length of fiber optic cable for a single switched link should not exceed: • 1000BASE-SX/LX: 550 m (1805 ft) for multimode fiber or 5 km (3.2 miles) for single-mode fiber. • 100BASE-FX: 2 km (1.24 miles) for multimode fiber or 20 km (12.43 miles) for single-mode fiber.
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.
• 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. Installing Optional Modules: Before mounting the switch, you may want to install optional modules.
Mount the device in the rack, using four rack-mounting screws (not provided). Figure 3-2. 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.
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.
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.
Note: The stacking feature requires that all stacking module ports be connected and the switches powered on. If one stack link is not connected, or if a switch is powered off, the stack will not function. Connecting to a Power Source...
Installing the Switch 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-driven configuration program can be accessed from a terminal or a PC running a terminal emulation program. The pin assignments used to connect to the serial port are provided in the following table.
Chapter 4: Making Network Connections Connecting Network Devices The V2H124-24FX switch is designed to be connected to 100BASE-FX network cards in PCs and servers, as well as to other switches. It may also be connected to remote devices using optional 100BASE-FX or 1000BASE-T/SFP modules.
Network Connections Instructions for making patch-panel connections in the wiring closet follow. Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel. If not already in place, attach one end of a cable segment to the back of the patch panel, and the other end to a modular wall outlet.
Attach one end of a multimode cable segment to the device’s MT-RJ connector. Figure 4-3. Making MT-RJ Fiber Port 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 an MT-RJ modular wall outlet that is connected to the wiring closet.
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.
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 has failed. Contact your local dealer for assistance. • Indicates the switch's self test has failed. Power cycle the switch to try and clear the condition. • If the condition does not clear, contact your local 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.
Appendix B: Cables Fiber Standards The current TIA (Telecommunications Industry Association) 568-A specification on optical fiber cabling consists of one recognized cable type for horizontal subsytems and two cable types for backbone subsystems. Horizontal 62.5/125 micron multimode (two fibers per outlet). Backbone 62.5/125 micron multimode or single-mode.
Cables 10/100BASE-TX Pin Assignments Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).
Crossover Wiring If the twisted-pair cable is to join two ports and either both ports are labeled with an “X” (MDI-X) or neither port is labeled with an “X” (MDI), a crossover must be implemented in the wiring. (When auto-negotiation is enabled for an RJ-45 module port, you can use either straight-through or crossover cable to connect to any device type.) EIA/TIA 568B RJ-45 Wiring Standard...
