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 is essential to coping with the network bottlenecks that frequently develop as computers and their busses get faster and more users use 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. 6 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. Switching Technology Another key development pushing the limits of Ethernet technology is in the field 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 making it possible for a local area network to be divided into different segments which don't compete with each other for network transmission capacity, giving a decreased load on each. The switch acts as a high-speed selective bridge between the individual segments. Traffic that needs to go from one segment to another is automatically forwarded by the switch, without interfering with any other segments. This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards. 7 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 and the setup and maintenance required make routers relatively impractical. Today's switches are an ideal solution to most kinds of local area network congestion problems. Features The 24-Port 1000BASE-T Gigabit Ethernet Switch was designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously. 24 1000BASE-T Gigabit Ethernet ports Supports Auto-Negotiation for speed and duplex mode Supports Auto-MDIX for each port Full/half duplex transfer mode for 10Mbps and 100Mbps Full duplex transfer mode for 1000Mbps Wire speed reception and transmission Store-and-Forward switching method IEEE 802. 3x flow control for full-duplex mode Integrated address Look-Up Engine, supports 32K absolute MAC addresses Supports 2M Bytes data buffer per device Extensive front-panel diagnostic LEDs 8 Unpacking and Setup This chapter provides unpacking and setup information for the Switch. Unpacking Open the shipping carton of the Switch and carefully unpack its contents. The carton should contain the following items: One 24-Port 1000BASE-T Gigabit Ethernet Switch Accessory pack: 2 mounting brackets and screws Four rubber feet with adhesive backing One AC power cord This User's Guide If any item is found missing or damaged, please contact your local reseller for replacement. Setup The setup of the Switch can be performed using the following steps: The surface must support at least 5 kg. The power outlet should be within 1. 82 meters (6 feet) of the device. 9 Visually inspect the power cord and see that it is secured fully to the AC power connector. Make sure that there is proper heat dissipation from and adequate ventilation around the Switch.
