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 AirLink101 5-Port 10/100/1000Mbps Gigabit Ethernet Switch User Guide 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. 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. AirLink101 5-Port 10/100/1000Mbps Gigabit Ethernet Switch User Guide Features The 5-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. • Five 1000BASE-T Gigabit Ethernet ports • Supports Auto-Negotiation for 10/100/ 1000Mbps and duplex mode • Supports Auto-MDIX for each port • Support Full/Half duplex transfer mode for 10 and 100Mbps • Support Full duplex transfer mode for 1000Mbps • Full wire speed reception and transmission • Store-and-Forward switching method • Supports 4K absolute MAC addresses • Supports 3.5Mbit RAM for data buffering • Extensive front-panel diagnostic LEDs • IEEE 802.3x flow control for full-duplex • Back pressure flow control for half-duplex AirLink101 5-Port 10/100/1000Mbps Gigabit Ethernet Switch User Guide Unpacking & Installation This chapter provides unpacking and setup information for the Switch. Unpacking Open the shipping carton and carefully unpack the contents. The carton contains the following items: • One 5-port 10/100/1000Mbps Gigabit Ethernet Switch • One external power adapter • Four rubber feet to be used for shock cushioning • This User's Guide If any item is missing or damaged, contact your local reseller for replacement. Installation The site where you install the Switch may greatly affect its performance. When installing, consider the following pointers: • Install the Switch in a fairly cool and dry place. See Technical Specification for the acceptable operating temperature and humidity ranges. • Install the Switch in a site free from strong electromagnetic source, vibration, dust, and direct sunlight. • Leave at least 10cm of space at the left and right hand side of the Switch for ventilation. • Visually inspect the DC power jack and make sure that AirLink101 5-Port 10/100/1000Mbps Gigabit Ethernet Switch User Guide it is fully secured to the power adapter. External Components This section identifies all the major external components of the switch. Both the front and rear panel is shown, followed by a description of each panel's feature. Figure 1.
