[. . . ] The nondisruptive and smooth evolution nature, and the dominating potential market base, virtually guarantee cost-effective and high performance Fast Ethernet solutions. 100Mbps Fast Ethernet is a standard specified by the IEEE 802. 3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is compatible with all other 10Mbps Ethernet environments, it provides a straightforward upgrade and takes advantage of the existing investment in hardware, software, and personnel training. 1 AirLive Ether-FSH2402NT User's Manual Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802. 3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet. Since it is compatible with all 10-Mbps and 100-Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company's existing investment in hardware, software, and trained personnel. The increased speed and extra bandwidth offered by Gigabit Ethernet are essential to coping with the network bottlenecks that frequently develop as computers and their busses get faster and more users using applications that generate more traffic. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as significantly speed up the traffic between your subnets. Gigabit Ethernet supports video conferencing, complex imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC's are able to perform 10 times the number of operations in the same amount of time. The phenomenal bandwidth delivered by Gigabit Ethernet was the most cost-effective method to take advantage of today's rapidly improving switching and routing internetworking technologies. And with expected advances in silicon technology and digital signal processing that enabled Gigabit Ethernet to eventually operate over unshielded twisted-pair (UTP) cabling, outfitting your network with a powerful 1000-Mbps-capable backbone/server connection creates a flexible foundation for the next generation of network technology products. 2 AirLive Ether-FSH2402NT User's Manual Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A switch increases capacity and decreases network loading by dividing a local area network into different segments, which don't compete with each other for network transmission capacity. The switch acts as a high-speed selective bridge between the individual segments. The switch, without interfering with any other segments, automatically forwards traffic that needs to go from one segment to another. By doing this the total network capacity is multiplied, while still maintaining the same network cabling and adapter cards. Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router, the setup and maintenance required make routers relatively impractical. Today switches are an ideal solution to most kinds of local area network congestion problems. 3 AirLive Ether-FSH2402NT User's Manual Features 24×10/100BASE-TX Fast Ethernet ports + 2×1000BASE-T Gigabit Ethernet ports Auto MDI-X for each port Full/half duplex transfer mode for 10/100Mbps Fast Ethernet ports Full duplex transfer mode for Gigabit Ethernet ports Wire speed reception and transmission Store-and-Forward switching method Integrated address Look-Up Engine, supports 8K MAC addresses Supports 2. 5Mbit RAM for data buffering Extensive front-panel diagnostic LEDs IEEE 802. 3x flow control for full-duplex Back pressure flow control for half-duplex Standard 19" Rack-mount size 4 AirLive Ether-FSH2402NT User's Manual UNPACKING AND INSTALLATION This chapter provides unpacking and installation information for the Switch.
