1. PRODUCT OVERVIEW This chapter provides the following information: • Product Description • Features • Front and Rear Panel Component Descriptions • Feature Summaries • Application Example Description This installation guide describes Enterasys Networks’ Vertical Horizon VH-8TX1UM/VH-8TX1MF Fast Ethernet switch. The switch provides 7 fixed 10Base-T/100Base-TX ports, plus an eighth port which can be selected between 10/100Base-TX and 100 Base-FX multi-mode or single-mode fiber.
The VH-8TX1UM/VH-8TX1MF switch is desktop mountable. LEDs on the front panel provide information about the operating status of the switch. The rear panel contains the power connector and serial console port. Features • Ports: - 7 fixed dual-speed 10/100Base-TX ports using RJ-45 connectors (MDI-X) - 1 port which can be selected between dual-speed 10/100Base-TX and 100Base-FX multi-mode or single-mode fiber - 1 serial console port • Switch Architecture: - 1 controller with 8 10/100 ports - IEEE 802.

fails for any reason, a disabled alternative is activated, thereby maintaining the connection. This prevents network traffic from circulating in an endless loop formed by multiple connections to the same LAN segment. Spanning Tree parameters are configurable using the Spanning Tree Configuration Menu of the console menus, the on-board Web agent, or via SNMP (see Appendix B, “Spanning Tree Concepts,” in the Management Guide for more information).
An RS-232 connection, using a DB-9 connector, is included on the rear panel for system management. Serial console management can be performed out-of-band using a terminal or computer running communications software. You can connect directly to the RS-232 port on the rear panel, or make a connection via a modem. See the Management Guide for information on managing the VH-8TX1UM/ VH-8TX1MF switch via the serial console.
• Event: a function that operates with the Alarm group to define an action that will be taken when an alarm condition occurs. The event may write a log entry and/or send a trap message. Note that RMON statistics and other information can only be viewed using a connection to the on-board Web agent or via other compatible SNMP management applications.
address that matches one in the authorized list will be forwarded, all other packets will be dropped. Note that port security is disabled on all ports by default, but can be enabled on a per-port basis by using the console interface menus, the on-board Web agent, or via SNMP. Broadcast Suppression Broadcast suppression is a system that prevents a high level of broadcast traffic from overwhelming the network.
that could add to a congestion condition. The VH-8TX1UM/VH-8TX1MF switch supports flow control per the IEEE 802.3x standard. Note that flow control is disabled on all ports by default but can be enabled on a per-port basis by using the console interface menus, the on-board Web agent, or via SNMP. See Appendix B, “Flow Control,” for more information on this feature. NOTE: If flow control is desired for one port, it is recommended that it be enabled on all ports.
Factory Defaults Table 1-3 lists the default settings for switch configuration parameters. Each parameter can be changed via the console menus or Telnet. Table 1-3.
Parameter Default Value Virtual LANs Acceptable VLAN Frame Type All Configurable PVID Tagging Yes GVRP Disabled Untagged VLAN Group Assignment 1 VLAN Ingress Filtering False VLAN Learning IVL Application Examples The exploding popularity of the Internet and of corporate intranets, as well as new, high-bandwidth desktop applications, are driving the demand for Fast Ethernet.
Client/Server Network Application To improve workstation performance in a client/server environment, the VH-8TX1UM/VH-8TX1MF switch can be configured to provide 200 Mbps full-duplex Fast Ethernet connections to servers by connecting each to a dedicated switch port (Figure 1-3). Users can be accommodated through connections to hubs, both at 10 Mbps and 100 Mbps speeds, through 10 Mbps switches with 100 Mbps uplinks, or through direct connections.
Local Backbone Application The VH-8TX1UM/VH-8TX1MF switch can be used in a local backbone application, connecting network segments together and providing fileserver access (Figure 1-4). Workgroup hubs are provided with a single connection to the switch while servers are put on dedicated 100 Mbps ports. Routers and other networking devices can connect off of the switched backbone as well.

Mounting the Switch on a Table or Shelf You can mount the switch on a table or shelf. Locate the switch in a position that allows access to the front panel RJ-45 ports, visibility of the port LEDs, and access to the rear-panel modules and power cord. Make sure that the mounting surface can safely support the switch and that there is adequate space around the switch for ventilation and cooling. 1. The switch ships with four (4) rubber feet.
Mounting the Switch in a Rack The switch ships with two (2) multi-position mounting ears and four (4) mounting screws. NOTE: The mounting screws are used to attach the mounting ears to the switch. Once the ears are attached to the switch, you will need to provide appropriate screws to mount the switch in a rack. Figure 2.1 shows the orientation of the mounting ears for attaching the ears to the switch for a rack mount application. Mount the switch with the front panel facing forward. Do the following: 1.
Connecting a Terminal to the Console Port The console port is a serial RS-232 interface port that enables a connection to a terminal for performing switch monitoring and configuration functions. The terminal may be a PC or workstation running terminal emulation software, or a terminal configured as a Data Terminal Equipment (DTE) connection. Alternatively, this port can be connected to an external modem to enable remote dial-in management.
2. Connect one end of the interface cable directly to the switch’s console port and tighten the retaining screws. 3. Connect the other end of the interface cable to a terminal (in some instances, an adapter may be required to make this connection). 4. From your terminal, start the terminal emulation program. 5. Configure the terminal to the following communication settings: VT100 emulation, 19200 baud, no parity, 8 data bits, 1 stop bit, no flow control, ASCII character set.
Powering the Switch To supply power to the switch, connect the power cord to the switch and to a grounded three-prong wall outlet (Figure 2-3). See Appendix A, “Technical Specifications” on page 25 for more information regarding specific international power cord requirements. Figure 2-3. Connecting the Power Cord The Power LED lights green (see Figure 1-1). If it does not, check to make sure that the power cable is plugged in correctly and that the power source is good.
Network Cable Requirements Copper Table 2.1 specifies the cable types and length constraints for the various copper interfaces on the VH-8TX1UM/VH-8TX1MF. Table 2-1. Copper Cable Specifications Interface Type Cable Requirement Maximum Length 10Base-T Category 3 or 5 Unshielded Twisted Pair (UTP) 100 m (328 ft.) 100Base-TX Category 5 UTP 100 m (328 ft.) Fiber Table2.2 specifies the fiber type, bandwidth requirement, and length constraint for the Fast Ethernet fiber interface. Table 2-2.
10Base-T/100Base-TX Ports The 10Base-T/100Base-TX ports use RJ-45 connectors. Figure 2-4 shows an RJ-45 connector being inserted into a port. Figure 2-4. Inserting an RJ-45 Connector into a Port The ports on the base unit are wired with the MDI-X function implemented. These ports interface to UTP cabling for connection to 10Base-T or 100Base-TX network segments or end-stations. These UTP connections meet the requirements of ISO 8877, specified by 10Base-T, Section 14 of the IEEE 802.3 specification.
100Base-FX Fiber Port The 100Base-FX fiber port uses an SC connector. Figure 2-5 shows an SC fiber connector being inserted into the fiber port on the VH-8TX1UM/VH8TX1MF. Figure 2-5. Inserting an SC Fiber Connector into the Fiber Port The fiber uplink on the VH-8TX1MF supports multi-mode 62.5/125µm fiber with SC connectors. The fiber connectors are configured as a receive (RX) / transmit (TX) pair. The fiber uplink on the VH-8TX1UM supports single-mode 10/125 µm fiber with SC connectors.

APPENDIX B. FLOW CONTROL Flow control is a mechanism which allows you to protect the switch from overload conditions and to keep additional traffic off the network when excessive congestion will result. Figure B-1 illustrates flow control for both half- and full-duplex applications. Figure B-1. Flow Control for Half- and Full-Duplex Applications Each port of the switch has a transmit queue which buffers frames to be sent out on that port.
