Chapter 1: Product Description Maximum Distance Each twisted pair port has a maximum operating distance of 100 m (328 feet). Type of Cabling For 10 Mbps operation, Category 3 or better 100 ohm shielded or unshielded twisted pair cabling is required. For 100 or 1000 Mbps operation, Category 5 and Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted pair cabling is required.
eco-friendly The eco-friendly switch on the front panel is multi-functional and shown in Figure 3. It may be used to enable all the port LEDs (out position) or Switch conserve power by turning off the port LEDs (in position). The switch functions are described in Table 2.
Chapter 1: Product Description Table 3 describes the system and port LEDs on the AT-GS900/16 and AT-GS900/24 switches. POWER AC Power Both the AT-GS900/16 and AT-GS900/24 switches have a single AC power supply socket on the back panel. To power ON or OFF the switch, Connector you connect or disconnect the power cord.
AT-GS900/16, AT-GS900/24 Gigabit eco-friendly Ethernet Switch Installation Guide 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 Every hardware device on your network has a unique MAC address.
Chapter 1: Product Description 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. Naturally, an end-node capable of operating in full-duplex can handle data much faster than an end-node that can only operate in half-duplex mode.
