AT-GS900/xE Gigabit Ethernet Switch Installation Guide Key Features The AT-GS900/xE Series switch has the following key features: Five or eight 10/100/1000 Mbps twisted pair ports with RJ-45 connectors System and port LEDs Auto MDI/MDI-X on all 10/100/1000 Mbps twisted pair ports Support half- or full-duplex mode on all 10/100/1000 Mbps twisted pair ports Auto-Negotiation (IEEE 802.3u-compliant) Flow control (IEEE 802.
Chapter 1: Product Description Hardware Feature Description The below sections describe the hardware features of the AT-GS900/xE Gigabit Ethernet switch: 10/100Base-TX Twisted Pair Ports Five or eight 10/100/1000 Mbps twisted pair ports System and port LEDs DC power jack The AT-GS900/xE Gigabit Ethernet switch features sixteen twisted pair ports. The features of the twisted pair ports are explained in the following sections.
AT-GS900/xE Gigabit Ethernet Switch Installation Guide Type of Cabling For 10 Mbps operation, Category 3 or better 100 ohm shielded or unshielded twisted pair cabling is required. For 100 Mbps operation, Category 5 and Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted pair cabling is required. Maximum Distance Each twisted pair port has a maximum operating distance of 100 meters (328 feet). Auto MDI/MDI-X All of the twisted pair ports on the switch are auto-MDI and IEEE 802.3abcompatible.
Chapter 1: Product Description DC Power Connector The AT-GS900/xE Gigabit Ethernet switch has a single DC power jack on the back panel. Refer to Appendix A, “Technical Specifications” on page 34, for the input voltage specifications. To power ON or OFF the switch, you connect or disconnect the power adapter.
AT-GS900/xE Gigabit Ethernet Switch Installation Guide A Few 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.
Chapter 1: Product Description Duplex Mode Duplex mode refers to how an end node receives and transmits data. If an end node can 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 end node is said to be operating in full-duplex mode.
AT-GS900/xE Gigabit Ethernet Switch Installation Guide Back Pressure and Flow Control To maintain the orderly movement of data between the end nodes, an Ethernet switch may periodically need to signal an end node to stop sending data. This can occur under several circumstances.
Chapter 1: Product Description Network Topologies This section illustrates two network topologies that you can create with the AT-GS900/xE switches: a power workgroup and collapsed backbone. Both types of topologies are described below. Power Workgroup Topology The topology shown in Figure 5 is commonly referred to as a power workgroup topology. Each workstation or end node is connected directly to a port on the AT-GS900/8E switch.
AT-GS900/xE Gigabit Ethernet Switch Installation Guide Collapsed Backbone In the topology illustrated in Figure 6, an AT-GS900/8E connects Fast Ethernet switches that have Gigabit Ethernet uplinks. This type of topology is often referred to as a collapsed backbone topology.
