1 INTRODUCTION
This section describes the features of the Switch, as well as giving some background information about Ethernet/Fast Ethernet, Gigabit Ethernet, and switching technology.
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speed LAN technologies are proposed to provide greater bandwidth and improve client/server response times. Among them, Fast Ethernet, or 100BASE-T, provides a non -disruptive, smooth evolution from the current 10BASE-T technology. The dominating market position virtually guarantees 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 Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Ethernet protocol.
Introduction 1
Stackable NWay Ethernet Switch User’s Guide
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 100Mbps Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps 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 Ether net 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.
Gigabit Ethernet enables fast optical fiber connections to support 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.
In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today and tomorrow’s rapidly improving switching and routing internetworking technologies. And with expected advances in the coming years in silicon technology and digital signal processing that will enable Gigabit Ethernet to eventually operate over unshielded twisted-pair (UTP) cabling, outfitting your network with a powerful 1000Mbps­capable backbone/server connection creates a flexible foundation for the next generation of network technology products.
2 Introduction
Stackable NWay Ethernet Switch User’s Guide
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 pr otocol transmitting among connected Ethernet, Fast Ethernet, or Gigabit 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 (from one port to another) is automatically forwarded by the switch, without interfering with any other segments (ports). This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards.
For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs beyond the “two-repeater limit.” A switch can be used to split parts of the network into different collision domains, for example, making it possible to expand your Fast Ethernet network beyond the 205 meter network diameter limit for 100BASE-TX networks. Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between existing 10Mbps networks and new 100Mbps networks.
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 TEG-S224 series of Switches can include one master (either a TEG-S224M or a TEG-S224MF) and up to three clients (TEG-S224S or TEG-S224SF). They are designed for easy installation and high performance in an environment where traffic on the network and the number of users increases continuously.
Switch features include:
Ports
? ?20 high performance NWay ports all operating at 10/100 Mbps
for connection to servers and hubs (19 ports 10/100 fixed Ethernet TP interface and one MDI-II/MDI-X jack connection are supported) (TEG-S224M and TEG-S224MF) or 22 high performance NWay ports all operating at 10/100 Mbps for connection to servers and hubs (20 ports 10/100 fixed Ethernet TP interface and two MDI-II/MDI-X jack connections are supported) (TEG-S224S and TEG-S224SF).
? ?All ports can be auto-negotiated between 10Mbps/100Mbps,
half-duplex or full duplex connections.
? ?Gigabit uplink/MDI-II (media dependent interface) slide-in
module in the rear panel for uplink to another Switch. One­port or two-port models are available (TEG-S224M and TEG­S224MF only).
4 Introduction
Stackable NWay Ethernet Switch User’s Guide
? ?RS-232 DCE console port for diagnosing the Switch via a
connection to a PC and Console/Out-of-band management (TEG-S224M or TEG-S224MF only).
? ?One slide-in module interface in the front panel for 1 or 2 ports
10/100M Ethernet connection. Three optional modules are available: 2-port TX, 2-port FX (MT -RJ), and 1-port FX (SC).
? ?Stacking Input/Output port slide-in module in the rear panel
for stacking to another device to implement a high-port count, manageable switch. Three-port module for master device and one-port module for a client device.
Performance features
? ?Store and forward switching scheme capability to support rate
adaptation and protocol conversion.
? ?Full and half-duplex for 10Mbps and 100Mbps connections. The
1000BASE-SX module operates at full-duplex only. Full-duplex allows the switch port to simultaneously transmit and receive data, and only works with connections to full-duplex capable end stations and switches. Connections to hubs must take place at half-duplex.
? ?Auto polarity detection and correction of incorrect polarity on
the receive twisted pair at each port.
? ?Data forwarding rate 14,880 pps per port at 100% of wire-speed
for 10Mbps speed.
? ?Data forwarding rate 148,800 pps per port at 100% of wire-
speed for 100Mbps speed.

? ?All LED indicators will momentarily blink. This blinking of
the LED indicators represents a reset of the system.
? ?The power LED indicator will blink while the Switch loads
onboard software and performs a self-test. After approximately 40 seconds, the LED will light continuously to indicate the Switch is in a ready state.
? ?The console LED indicator will remain ON if there is a
connection at the RS-232 port, otherwise this LED indicator is OFF.
? ?The 100M LED indicator may remain ON or OFF depending
on the transmission speed.
Power Failure
As a precaution, the Switch should be unplugged in case of power failure. When power is resumed, plug the Switch back in.

? ?Comprehensive LED indicators display the conditions of the
Switch and status of the network. A description of these LED indicators follows (see LED Indicators).
? ?An RS-232 DCE console port is used to diagnose the Switch via
a connection to a PC and Local Console Management (TEG­S224M and TEG-S224MF only).
? ?Nineteen or 20 high performance NWay ports all operate at
10/100 Mbps for connection to servers and hubs. All ports can be auto-negotiated between 10Mbps or 100Mbps.
? ?A slide-in module slot (labeled Slot1) for 10/100 Mbps Ethernet
ports can accommodate the following modules: 2-port TX, 2­port FX (MT -RJ), or 1-port FX (SC).
? ?One or two MDI-II uplink jacks are supported. Port numbers 1
and 2 on the TEG-S224S and the TEG-S224SF are equipped with MDI-X jacks for normal end-node connections and MDI-II jacks for uplink connections. Port number 1 on the TEG­S224M and TEG-S224MF are equipped with an MDI-X jack for normal end-node connection and an MDI-II jack for uplink connection.
Rear Panel
The rear panel of the TEG-S224S and the TEG-S224SF consist of a slot (labeled Slot2) for a Stacking input/output port and an AC power connector. The rear panel of the TEG-S224M and TEG-S224MF consist of two slots (labeled Slot2 and Slot3). Slot2 is for Stacking input/output ports Sio1, Sio2, and Sio3.

? ?The optional Gigabit Ethernet slide-in module is an
uplink/MDI-II (media dependent interface) port for uplink to another Switch (TEG-S224M and TEG-S224MF only). Two models are available, one-port and two-port.
? ?The Stacking input/output port slide-in module in the rear
panel is for stacking to another device to implement a high­port count, manageable Switch. The three-port module is for a master device and a one-port module is for a client device.
? ?The AC power connector is a three-pronged connector that
supports the power cord. Plug in the female connector of the provided power cord into this connector, and the male into a power outlet. Supported input voltages range from 100 ~ 240 VAC at 50 ~ 60 Hz.
Side Panels
The right side panel of the Switch contains two system fans (see the bottom part of the diagram below). The left side panel contains heat vents.

? ?The system fans are used to dissipate heat. The sides of the
system also provide heat vents to serve the same purpose. Do not block these openings, and leave adequate space at the rear and sides of the Switch for proper ventilation. Be reminded that without proper heat dissipation and air circulation, system components might overheat, which could lead to system failure.
Stack Operation
The TEG-S224M and the TEG-S224MF are intelligent Switches capable of acting as a master for up to three client Switches (TEG­S224S and TEG-S224SF). Each port is referred to by unit ID and port number in your TEG-S224 Series stack.
To set up a stack, a one-port Stacking input/output module is needed for each client Switch and a three-port Stacking input/output module is needed for the master Switch. Once the modules have been installed, use a cascade cable to connect each client Switch to the master Switch.
