Chapter 1: Product Description Ethernet Switching Basics An Ethernet switch interconnects network devices, such as workstations, printers, routers, and other Ethernet switches, so that they can communicate with each other by sending and receiving Ethernet frames. MAC Address Table Every hardware device on your network has a unique MAC address. This address is assigned to the device by the device’s manufacturer.
AT-GS900/16, AT-GS900/24 Fanless Gigabit Ethernet Switches Installation Guide Duplex Mode Duplex mode refers to how an end-node receives and transmits data. If an end-node can either receive or transmit data, but not both simultaneously, the end-node is operating in what is referred to as half-duplex mode. If an end-node can both receive and transmit data simultaneously, the endnode is said to be operating in full-duplex mode.
Chapter 1: Product Description Network Topologies This section illustrates two network topologies that you can create with the AT-GS900/16 and AT-GS900/24 switches: a power workgroup and collapsed backbone. Both types of topologies are described below. Power Workgroup Topology The topology shown in Figure 4 is commonly referred to as a power workgroup topology. Each workstation or end-node is connected directly to a port on the switch.
AT-GS900/16, AT-GS900/24 Fanless Gigabit Ethernet Switches Installation Guide Collapsed Backbone In the topology illustrated in Figure 5, an AT-GS900/16 switch connects Fast Ethernet switches that have Gigabit Ethernet uplinks. This type of topology is often referred to as a collapsed backbone topology.

AT-GS900/16, AT-GS900/24 Fanless Gigabit Ethernet Switches Installation Guide Reviewing Safety Precautions Please review the following safety precautions before you begin to install the switch or any of its components. Refer to the “Translated Safety Statements” document for translated safety statements in your language. The indicates that a translation of the safety statement is available in a PDF document titled “Translated Safety Statements” (613-000405) on the Allied Telesis website at www.
Chapter 2: Installation Selecting a Site for the Switch Observe the following requirements when choosing a site for your switch: If you plan to install the switch in an equipment rack, ensure that the rack is safely secured and that it will not tip over. Devices in a rack should be installed starting at the bottom, with the heavier devices near the bottom of the rack. If you are installing the switch on a table, ensure that the table is level and secure.
