Chapter 1: Introduction Switching Technology The Ethernet Switch allows simultaneous transmission of multiple packets via an internal high-speed data channel. This means that it can partition a network more efficiently than bridges or routers. The Ethernet Switch is therefore fast being recognized as one of the most important building blocks for today’s networking technology.
Fast SwitcHub-2se User’s Guide Accton’s Smart Extender Accton’s Fast SwitcHub-2se can boost network bandwidth fourfold (i.e., if running at 100 Mbps and using full-duplex operation for both ports). It provides one 10/100 Mbps RJ-45 port for 10BASE-T or 100BASE-TX media attachment (which is automatically detected by the switch), and one 100 Mbps fiber optic port for 100BASE-FX media attachment via an SC or ST type connector.
Fast SwitcHub-2se User’s Guide speed 100BASE-TX or conventional 10BASE-T networks to the newer generation of 100BASE-FX devices; or can be used to significantly extend a 100BASE-TX or 10BASE-T network with an intermediate fiber optic link (i.e., by chaining two or more switches). Moreover, by breaking your network into smaller and more manageable segments, each linked to the larger network with a switch, the maximum distance for communications between end-nodes is unlimited.
Fast SwitcHub-2se User’s Guide dynamically changes the way it handles data passing through the switch based on the current error rate. These switching alternatives start at standard cutthrough for a clean data environment, change to fragment-free cut-through for a moderate error rate, and then progress to store-and-forward for a highly contentious environment. By using this method, the Fast SwitcHub-2se delivers the best networking performance under any environment.
Fast SwitcHub-2se User’s Guide • Uses “on the fly” cut-through technique to transport packets • Transparent bridging function supported • Address learning function to build the routing information database • Operates at maximum packet filtering and forwarding rate • Supports multimode fiber optic backbone of up to 2 kilometers for a dedicated link (i.e., a full-duplex connection) or 180 meters for a shared collision domain (i.e.
Chapter 2: Setup and Configuration This chapter provides information on pre-installation requirements, establishing network connections, and configuring the system. Pre-Installation Requirements Before you start making network connections to the SwitcHub, make sure you can provide the right operating environment, including power requirements, and proximity to other network devices that are to be connected. Verify the following installation requirements: • Power requirements: 100 to 240 VAC at 50 to 60 Hz.
Fast SwitcHub-2se User’s Guide Making RJ-45 Connections 1. Prepare a straight-through twisted-pair cable with RJ-45 plugs at both ends. 2. If you are making a connection to a server or workstation (i.e., a dedicated connection to an end-node device), be sure that it has a properly installed 100BASE-TX or 10BASE-T network interface card. Attach one end of the cable to the MDI-X station port on the switch and the other end to the RJ-45 port of the device’s network interface card.
Fast SwitcHub-2se User’s Guide Making Fiber Optic Connections 1. Prepare a pair of fiber optic cables with SC or ST type connectors at both ends. SC-Type Connector ST-Type Connector 2. If you are making a connection to a server or workstation, be sure that it has a properly installed 100BASE-FX network interface card. Connect the Rx/Tx jacks on the target device to the Tx/Rx jacks on the switch. - When using fiber optic cabling, the maximum length between two switches can be up to 2 kilometers.
Fast SwitcHub-2se User’s Guide For a sample calculation, assume the following values: • cable gauge - 62.5/125 mm, which means a 13 dB power budget, • 2 patch panels between the switches, each with 0.5 dB power loss, and 1 splice with 0.4 dB power loss (i.e., 2 * 0.5 + 0.4 = 1.4 dB power loss for intervening devices), and • inherent power loss in the cable is 4.5 dB/km The maximum cable length is therefore: m ≤ 13 dB - 1.4 dB ≤ 2.58 km 4.
Fast SwitcHub-2se User’s Guide Providing Power to the SwitcHub 1.
