10/100 Fast Ethernet Switch User’s Guide P REFACE Congratulations on your purchase of the 10/100 Fast Ethernet Switch. This device integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in a highly flexible desktop package. Usage/Scope This manual discusses two 10/100 Fast Ethernet Switch models (ten port and eighteen port). Where necessary, the text distinguishes between them, otherwise all information provided is applicable to either model.
• Understanding of how to install local area networks (LANs). Manual Organization Chapter 1 Overview Describes the product, its features, packing list, and the front and rear panels. Chapter 2 Installation Provides detailed instructions on installing the 10/100 Fast Ethernet Switch. Chapter 2 includes information on installation, connecting power, network connections, setting the communications mode, and provides some network configuration examples.
10/100 Fast Ethernet Switch User’s Guide 1 2 O VERVIEW Introduction The DES-810 and DES-818 Fast Ethernet Switches are ideal for network managers who want to boost workgroup performance easily by microsegmenting a 10Mbps LAN while adding 100Mbps links. They are also excellently suited to provide dedicated Fast Ethernet connections to key network servers. Each switch integrates 100Mbps Fast Ethernet with 10Mbps Ethernet networks seamlessly.
LAN while preserving your initial investment and use of 10Mbps Ethernet LANs. 100Mbps Fast Ethernet Introduction Computers today have become increasingly powerful, with the capability to accommodate very sophisticated uses such as multimedia applications, video-conferencing, and CAD/CAM. To utilize these technologically advanced applications more efficiently, there is also a growing demand for faster networks that can handle heavy network traffic.
10/100 Fast Ethernet Switch User’s Guide in the same configuration. Please note that the punch-down blocks in the wiring closet must also be Category 5 certified. If these blocks do not meet the standard, an upgrade is necessary. Topology A Fast Ethernet workgroup is configured in a star topology and is built around a maximum of two repeaters.
Hubs Unlike 10BASE-T hubs which are all functionally identical, Fast Ethernet hubs are divided into two distinct types: Class I and Class II. A Class I hub repeats all incoming signals on one port to the other ports by first translating them to digital signals and then retranslating them back to line signals. These translations are necessary when connecting various network media to the same collision domain, such as when combining two wire-pair 100BASE-TX media with four wire-pair 100BASE-T4 media.
10/100 Fast Ethernet Switch User’s Guide Switching Technology Switching is fast becoming the industry standard for pushing the limits of existing Ethernet networks. A switch bridges Ethernet packets between Ethernet and Fast Ethernet LAN segments at the MAC address level of the Ethernet protocol. The difference between switched Ethernet (10Mbps, 100Mbps, or both) and traditional Ethernet is analogous to the difference between a private phone line and a party line.
installed base. Compatibility with 10Mbps Ethernet ensures that users will be able to migrate to Fast Ethernet at a pace appropriate to their installation and needs. 10/100 Switching Technology An integral extension of Fast Ethernet, 10/100 switching provides not only a 100Mbps high-speed connection for carrying aggregated 10Mbps traffic, it also handles the necessary conversion of MAC between 10BASE-T and 100BASE-TX.
10/100 Fast Ethernet Switch User’s Guide • High-speed uplink port for connecting to a higher tier switch or other device. • Flexibility of application: from segmentation of a large LAN to clientserver maximization to dedicated connections for high-priority single users. • Support for IEEE 802.3, 10BASE-2, 10BASE-T, IEEE 802.3u and 100BASE-TX standards. • Εxtensive LED indicators to facilitate troubleshooting and monitoring of the product’s operating status.
Front Panel The 10/100 Fast Ethernet Switch front panel includes network connectors and LED indicators for ease-of-use. Figure 1 10/100 Fast Ethernet Switch Front Panel Ports The product comes with twisted-pair ports. These ports can be used to connect to individual stations in need of faster access, to segment heavily utilized LANs, and/or to provide higher bandwidth access to a key server in a client-server environment.
10/100 Fast Ethernet Switch User’s Guide • Connect single users either to provide power users with greater access and thus speed, or multiple users for high bandwidth access to a shared network server. • Uplink connections for lower-tier switches. 10/100Mbps Ports The 10/100Mbps twisted-pair ports are standard RJ-45 connectors for use with unshielded or shielded twisted-pair (UTP/STP) wiring.
Note: Full-duplex mode can only be used for connections to other switches or to network stations. Connections to hubs must use halfduplex mode only. Uplink Port The uplink port is used for higher-tier connections to more advanced switches or other network devices. Please note that if you are using the uplink port, you will be unable to use port one as these two ports are logically linked.
10/100 Fast Ethernet Switch User’s Guide The following section describes these indicators in detail. • Power LED This indicator is green when power is supplied to the device. The Power LED lights when you connect the power cable to the power receptacle at the rear of the device, and then plug it in to a power outlet. • Link/Act LED This indicator is green when the respective port is properly connected to a powered-on device and blinks green when packets are being transmitted or received.
Duplex Mode Switch The 10/100 Fast Ethernet Switch supports full duplex operation on all 10 and 10/100 ports. When operating in full duplex mode, ports can transmit and receive simultaneously. Each 10Mbps port must be manually set to the proper duplex mode (half or full), but the switch can be set to auto-detect the duplex mode for ports 1 and 2 (the two 10/100Mbps ports). To change the duplex mode, change the Duplex Mode DIP switch setting on the back of the 10/100 Fast Ethernet Switch.
10/100 Fast Ethernet Switch User’s Guide 2 3 I NSTALLATION This chapter describes the installation procedure for the 10/100 Fast Ethernet Switch. The chapter includes information on installation, connecting power, connecting network cables, setting the port duplex mode, and some network configuration examples. Installation Site When installing the switch, choose a sturdy, level surface in a ventilated area that is dust free and away from heat vents, warm air exhaust from other devices and direct sunlight.
For a detailed list of the product’s technical specifications, refer to Appendix A, Specifications. Installing on a Desktop or Shelf When installing the product you need to attach the rubber feet included with the device. Attach these cushioning feet on the bottom at each corner of the device. Allow enough ventilation space between the device and the objects around it.
10/100 Fast Ethernet Switch User’s Guide Connecting Power Power is supplied to the 10/100 Fast Ethernet Switch through an AC power cord. The AC power input voltage ranges from 100 to 240 VAC. A power cable is included with the device. Figure 5 Connecting Power Network Connections If any port on the 10/100 Fast Ethernet Switch is set for full-duplex operation, the device (or LAN) connected to that port should also be set for full-duplex operation.
Switch. When connecting a workstation or a server running at 100Mbps, a standard 100BASE-TX adapter must be installed. When running at 10Mbps, ports 1 and 2 are functionally identical to the 10Mbps ports described below. 10Mbps Ports These ports require Category 3, 4, or 5 unshielded twisted-pair or shielded twisted-pair (UTP/STP) cable. They can be used to connect to individual workstations, servers or other 10BASE-T devices.

switch up. To set for half-duplex, set the duplex switch down. To set either or both ports 1 and 2 to auto duplex mode detect, set the corresponding switch down. Figure 6 Setting the Duplex Mode Note: Full-duplex mode can only be used for connections to other switches, network servers, or network stations. Connections to hubs must use half-duplex mode only. Network Configuration Examples This section provides sample configurations showing ways you might use the 10/100 Fast Ethernet Switch.
10/100 Fast Ethernet Switch User’s Guide LAN Microsegmentation Perhaps the principal purpose for the 10/100 Fast Ethernet Switch is to microsegment an existing LAN to improve network latency rates and increase overall performance. The 100Mbps ports on the switch can be used to connect those segments which require greater throughput.
