Introduction
This chapter describes the features of the Switch and some background information about Ethernet and Fast Ethernet switching technology.
Fast Ethernet Technology
The growing importance of local area networks (LANs) and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times. Among them, 100 BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution from the current 10 BASE-T technology. The non-disruptive and smooth evolution nature, and the dominating potential market base, virtually guarantee cost effective and high performance Fast Ethernet solutions in the years to come.
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 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.
Switching Technology
Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A

switch bridge 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 LAN. A switch increases capacity and decreases network loading by dividing a LAN into different segments that 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 automatically forwards traffic that needs to go from one segment to another without interfering with any other segments. This multiplies the total network capacity while maintaining the same network cabling and adapter cards.
For Fast Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs beyond the “two­repeater limit.” A switch can be used to split parts of the network into different collision domains, making it possible to expand your Fast Ethernet network beyond the 205-meter network diameter limit for 100 BASE-TX networks. Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between the existing 10Mbps networks and the new 100Mbps networks.
Switching LAN technology is an improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment LANs, 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 LAN congestion problems.

Features
The Switch was designed for easy installation and high performance in an environment where traffic on the network and the number of user increase continuously.
The Switch, with its rack size, is specifically designed for middle- to large-sized workgroups. The Switch provides immediate access to a rapidly growing network through a wide range of user-reliable functions.
The Switch is ideal for deployment with multiple high­speed servers for shared bandwidth 10Mbps or 100Mbps workgroups. With the highest bandwidth 200Mbps (100Mbps full-duplex mode), any port can provide workstations with a congestion-free data pipe for simultaneous access to the server.
The Switch is expandable by cascading two or more switches together. Since all ports support 200Mbps, the Switch can be cascaded from any port and to any number of switches.
The Switch is a perfect choice for systems that will be upgraded to Fast Ethernet in the future. Ethernet workgroups can connect to the Switch now, and change adapters and hubs anytime later without needing to change the Switch or reconfigure the network.
The Switch combine dynamic memory allocation with store­and-forward switching to ensure that the buffer is effectively allocated for each port, while controlling the data flow between the transmit and receive nodes to guarantee against all possible packet loss.

The Switch is an unmanaged 10/100Mbps Fast Ethernet Switch that offers solutions in accelerating small Ethernet workgroup bandwidth. Other key features are:
Auto MDI/MDIX feature automatically detects and corrects for crossover cables and allows direct switch­to-switch connection.
Store and forward switching scheme capability. As the result of complete frame checking and error frame filtering, this scheme prevents error packages from transmitting among segments.
Auto-negotiation for any port. This allows for auto­sensing of speed (10/100Mbps) and duplex-mode (half or full-duplex) thereby providing you with automatic and flexible solutions in your network connections.
IEEE 802.3x flow control for full-duplex.
Back pressure flow control for half-duplex.
Data forwarding rate per port is at wire-speed for both
10Mbps and 100Mbps speed.
Data filtering rate eliminates all error packets, runts, etc., per port at wire-speed for both 10Mbps and 100Mbps speed.
4K active MAC address entry table with self-learning and table ageing.
1,024-KBytes RAM of buffer per device.

Connecting the Switch
This chapter describes how to connect the Switch to your Fast Ethernet network.
Connecting a PC to the Switch
A PC can be connected to the Switch via a two-pair Category 3, 4, 5 UTP/STP cables. Connect the PC (equipped with a RJ-45 10/100Mbps phone jack) to any of the 32 ports (1 to 32)
18 AirLink+
Page 19
32-Port 10/100Mbps Ethernet Switch User Guide
The LED indicators for the PC connection depend on the LAN card capabilities. If LED indicators are not lit after making a proper connection, check the PC LAN card, the cable, the Switch conditions, and connections.
Connecting a Hub or Switch to the Switch
You can connect the Switch to another switch or other devices (i.e., routers, bridges, etc.) via a two-pair Category 3, 4, 5 UTP/STP cable.
The following are LED indicator possibilities for a PC or other devices to Switch connection:
1. The LINK/ACT LED indicator lights green when connected at 100 Mbps or lights amber when connected at 10 Mbps.
2. The COL LED indicator lights green when a collision happens.
3. The FDX LED indicator lights green when operating at full duplex. This LED is off when it the switch is operating at half duplex.
Port Speed & Duplex Mode
After plugging the selected cable to a specific port, the system uses auto-negotiation to determine the transmission mode for any new twisted-pair connection:
If the attached device does not support auto-negotiation or has auto-negotiation disabled, an auto-sensing process is initiated to select the speed and set the duplex mode to half­duplex.
