Introduction
This section provides you with useful Fast Ethernet, hub and switching technology background.
Fast Ethernet Technology
In July 1993, the Fast Ethernet Alliance was formed by a group of networking companies with the goal of drafting the 802.3u
100BaseT specifications of the Institute of Electrical and Electronics Engineers (IEEE). This group recognized that existing
applications and the flood of new multimedia, GroupWare, imaging, and database products could easily overwhelm a traditional
10BaseT Ethernet. In order to ensure a cost effective, simple migration from 10BaseT Ethernet to 100BaseT Fast Ethernet, the
group determined to maintain the Ethernet transmission protocol Carrier Sense Multiple Access Collision Detection (CSMA/CD),
support popular cabling schemes and to maintain the upper-layer protocols and software that already ran on LAN workstations.
Because it is compatible with all other 10Mbps Ethernet environments and uses your company’s existing investment in hardware,
software, and personnel training, Fast Ethernet technology is regarded as being the inevitable market dominator. This means
that you can now start to make a cost effective, incremental migration to Fast Ethernet and rest assured that the future will offer a
vast array of low cost products to keep pace with your growing LAN needs.
Cables and Connectors
Fast Ethernet supports category 5 unshielded twisted-pair (UTP) cable and category 5 shielded twisted-pair (STP) cable.
These cables use the same RJ-45 connector as used with 10BASE-T cables wired in the same configuration.
Topology
Star topology is the fundamental structure of a Fast Ethernet LAN.
A single collision domain LAN is sufficient for users with a small number of end stations and servers.
Within a single collision domain LAN, you can use one class I repeater hub or two class II repeater hubs to connect your end
stations and servers. You can use stackable hubs to increase the total number ports within each collision domain.
A switch is used to create other collision domains within your overall LAN. These collision domains are separate LANs within
your overall LAN.
A switch allows all of these collision domains to communicate with each other.
A switched line is a separate collision domain that allows you to use one Class I repeater hub or two Class II repeater hubs to
connect your end stations and servers. You can use stackable hubs to increase the total number ports within each collision
domain.
You can also dedicate a separate collision domain to heavily used servers or end stations with large bandwidth needs.
Network Diameter
The network diameter is the total length of cable between two end stations within the same collision domain.
Because of the high speed of Fast Ethernet and adherence to the EIA/TIA 568 wiring rules, the maximum diameter of a Fast
Ethernet collision domain is 205 meters.
The maximum 10Base-T Ethernet collision domain diameter is 500 meters.
Fast Ethernet Hub Technology
Class I Fast Ethernet Hubs
Class I hubs must be used when connecting differing network media such as two wire-pair 100BASE-TX media with four wirepair 100BASE-T4 media within the same collision domain.
The hub receives line data from any port, translates it into a digital signal, retranslates the signal back into the appropriate line
data and repeats it to all other ports.
If a Class I hub is used in a collision domain, no other hubs may be used within that collision domain.
Class II Fast Ethernet Hubs
Class II hubs are used when all media within the collision domain is the same (all TX, for example).
The hub receives line data from any port and directly repeats it to all other ports.
A maximum of two Class II hubs can be used within one collision domain.
Stackable Class II Fast Ethernet Hubs
You can increase the port density within a collision domain by using stackable Class II hubs.
When hubs are stacked, they function as one hub. Consequently, you can have up to two stacks of Class II hubs within one
collision domain.
The stacked hubs receive line data from any port and directly repeat it to all other ports within the stack.
Dual-Speed Ethernet Hub Technology
Dual-Speed Ethernet hubs are an indispensable step in the migration of your existing 10Mbps Ethernet to 100Mbps Fast Ethernet.
This type of hub accommodates both 10Mbps Ethernet and 100Mbps Fast Ethernet on the same LAN.
A Dual-Speed Ethernet hub contains two separate repeaters within the same unit: one 10Mbps repeater and 100Mbps repeater.
The unit automatically detects the speed of the signal and routes it to the corresponding repeater. The repeater then sends the
signal to all other ports using that signal speed.
Dual-Speed Ethernet Hub with Built-in Bridge Module
A dual-speed Ethernet hub with bridging capabilities retains the structure of a regular dual-speed hub with the addition of an
embedded bridge module. This allows your 10Mbps devices and 100Mbps devices to seamlessly exchange data
Switching Technology
A switch creates a separate collision domain by dedicating a full 100Mbps line through each port. This allows you to use one
class I repeater hub or two class II repeater hubs to connect your end stations and servers within that domain. You can use
stackable hubs to increase the total number ports within each collision domain.
A switch uses store and forwarding technology to transfer data between collision domains at the MAC address level of the
Ethernet protocol. This means that data is transferred only to the data’s destination collision domain. The data is not
transferred to other collision domains, which allows your total LAN capacity to be increased without the need to invest in new
media infrastructure.
By creating separate collision domains and communicating between them, a switch allows you to overcome the two-hub limit of
Fast Ethernet topology.
You can also use a switch to dedicate a full 100Mbps line to power workstation users and servers.
Switches with bridging technology are ideal for facilitating data transfer between your 10Mbps legacy devices and your new
100Mbps devices.
Switches have lower latencies than the previous generation of network bridges; they use your existing network and do not require
the use of software for installation.
These factors make switches the best solution for most of your LAN congestion problems.
Gigabit Technology
Gigabit Ethernet is an extension to highly successful 10Mbps and IEEE 802.3 Ethernet standards. Offering a raw data bandwidth
of 1000Mbps, Gigabit Ethernet maintains full compatibility with the huge installed base of Ethernet node. The 1000Base-X
Gigabit Ethernet standard was ratified In June 1998 after more than two years of intense effort Within the IEEE 802.3 Ethernet
Committee .The key objective of the 802.3z Gigabit Ethernet Task Force was to develop a Gigabit Ethernet standard that
encompassed the following:
u Utilized the IEEE 802.3 Ethernet frame formats
u Utilized the CSMA/CD assess method
u Addressed backward compatibility with 10Base-T and 100Base-T technologies
u Allowed half-and full-duplex operation
Gigabit Ethernet common Cabling:
u 1000Base-SX (“S” for short wavelength)
u 1000Base-LX (“L” for long wavelength)

About Ethernet Switch
The Ethernet Switchs are multi-speed network devices combining Ethernet, Fast Ethernet and Gigabit Ethernet capabilities in a
single compact, rack-mountable cabinet. Combining 10Mbps Ethernet, 100Mbps Fast Ethernet and Gigabit Ethernet interfaces in
one unit allows these switches to unclog existing LANs and provide a path to efficient, high-speed networking.
The Ethernet Switch provides 16 10/100Base-TX ports, plus 2 slots for 3 optional different slide-in modules. It can consist of 8
port 10/100Base-Tx module, 4 x 100Base-FX module, and one 1000Base-SX/LX Gigabit module. Any of the above modules can
be integrated to give up to many different configurations. Only choose the right combination of port types to fit your network
needs. This Switch can bring a high performance, easy upgrade and cost-effectively network.

Planning your Network
Before you install your Switch, you should review the guidelines for setting up Ethernet networks. Further, you should plan
your network to take maximum advantage of its switching capabilities.
10Base-T Ethernet Network Guidelines
♦ The maximum length of a 10Base-T cable segment is 100 meters (328 feet).
♦ The maximum number of nodes on a 10Base-T segment is one (1) for regular 10Base-T.

♦ The maximum network diameter is 500 meters (1,640 feet) for Ethernet networks.
♦ The maximum number of segments between any two nodes in the network is five.
♦ The maximum number of hubs or repeaters between any two nodes in the network is four.
100Base-TX Ethernet Network Guidelines
♦ The maximum length of a 100Base-TX cable segment is 100 meters (328 feet).
♦ The maximum number of hubs on a 100Base-TX segment is one if using Class I hubs and two if using Class II hubs.
♦ The recommended cable type is EIA/TIA Category 5 untwisted-pair.
♦ The maximum network diameter is 200 meters (656 feet) when using Class I hubs and 205 meters (672.5 feet) when using
Class II hubs.
100Base-FX Network Guidelines
♦ In half duplex mode, the fiber optic segment cannot exceed 412m (1,135ft) in length.
♦ In full duplex mode, the fiber optic segment cannot exceed 2km (6562 ft) in length.
1000Base-SX and LX Network Guideline
1000Base-SX
♦ In Multi-mode, the fiber optic segment cannot exceed 220m (62.5/125µm) or 500m (50/125µm) in length, or 275m
for the ISO/IEC 11801 building wiring standard which specifies 200/500 Mhz*km multimode fiber.
1000Base-LX
♦ In Multi-mode, the fiber optic segment cannot exceed 550m(62.5/125µm) or 550m(50/125µm) in length.
♦ In single mode the fiber optic segment cannot exceed 10km(9/125µm).
Network Planning
Using a switch can expand network topologies and enhance network performance.
Each port on a switch connects to a separate network with its own collision domain. Separating networks with these switches
allows you to expand 10Base-T networks past the four-hub limit and expand 100Base-TX networks past the one or two hub limit.
These switches also filter incoming traffic. On standard hubs and repeaters, any data received on a port is forwarded to all of the
other ports. On switches, data received on one port is forwarded only to the port of the destination device, and if the traffic is
local, the data is not forwarded at all. Also, switches can forward multiple data transaction at once.
To expand your network topology or enhance network performance, use the Switch as collapsed backbone or to increase file
server performance, to segment large networks, to interconnect 10Mbps networks with 100Mbps networks, or to overcome the
limitations of 10Base-T and 100Base-TX networks.
Expanded Networks
You can expand your 10Base-T or 100Base-TX or 1000Base-SX/LX network beyond its hub limit by adding a Switch.
10Base-T Networks
10Base-T Networks are limited to four hubs between any two nodes. By adding your Switch to a network, you can divide that
network into segments with their own collision domains. In other words, you can connect one 10Base-T network with four hubs
to your Switch. Then you can connect another 10Base-T network with four hubs to your Switch. You will then have one network
with two collision domains, allowing four hubs on each port.
Figure 3-1. Expanding your 10Base-T Network
100Base-TX Networks
The hub limit of a 100Base-TX network depends on the class of the hub in the network. With a Class I hub, the network is
limited to one hub. With a Class II hub, the network is limited to two hubs.
However, you can expand your 100Base-TX network that includes either class of hub by adding a Switch. With the Switch
added to your 100Base-TX network, you can separate that network into individual segments with their own collision domains.
In other words, you can connect one 100Base-T network with one or two hubs to the Switch, and you can connect another
100Base-TX network with one or two hubs to the Switch. You will then have one network with two collision domains.
Figure 3-2. Expanding your 100Base-TX network (Class I)
Collapsed Backbone Link
Traditionally, bridges and routers have been used to link local area networks into one interconnected network. But these devices
involve difficult management and long traffic delays.
The Switch provides multi-port bridges with short delays, easy setup and maintenance, making it ideal for backbone links. Also,
the Built-in filtering on this hub decreases network traffic, while the multiple ports that communicate simultaneously increases
network performance.
One or more of your hub's 100Mbps or 1000Mbps ports can be used as a high-speed backbone link to other hubs serving as
collapsed backbones.
Figure 3-3. Switch 100/1000 Hub in a collapsed backbone link
File server Link
100Base Solution
With a fileserver link, you can increase file server performance by increasing the Hub's bandwidth between one or more
fileservers and the workgroups they serve.
If you connect 10Mbps workgroup hubs to the 10Mbps ports on the Switch, traffic in one workgroup will not interfere with the
performance of another workgroup.
Figure 3-4. Fileserver Link
Connecting servers through 100Base-TX ports increases performance to the clients, even if the clients are on 10Base-T segments.
Because multiple 10Base-T devices can access the file server at the same time through a 100Base-TX connection, performance
increases to beyond the performance of standard 10Base-T or 100Base-TX hubs. Operating the Switch at full duplex further
increases performance
1000Base Solution
You can upgrade your server with a Gigabit Ethernet NIC, and introduce a Gigabit backbone switch too. This contain several
switch ports which provides much faster access to your server with minimum disruption. See Figure 3-5.
Multiport Bridge with High-Bandwidth Backbone
With a Switch, you can divide large network to ease congestion, and connect 10Base-T networks to 100Base-TX or 100Base to
1000Base networks for more flexibility. Adding your Switch to a large network creates more segments in that network. The
Switch built-in filtering function separates a segment's local traffic from network traffic, reducing the amount of network traffic
and easing congestion.
Figure 3-5. Used as a Multi-port Bridge
Using your hub, you can also connect 10Base-T networks and 100Base-TX and 1000Base-SX/LX networks together for more
flexibility in your network topology. As in the Figure 3-5 shown above, the Switch can connect through one port to a 10Base-T
network, and through another port, connect to a 100Base-TX port, creating one network. This switch can also connect to a
1000Base-LX or SX port.
Chapter 4
Installation
The Ethernet Switch can be installed quickly and easily. However, for an installation with minimum impact on the existing
network, please read this chapter carefully.
Installing a Ethernet Switch involves three steps:
1. Choosing a location
2. Supplying power
3. Connecting the switch
Choosing A Location
The location of the switch is based on the following criteria:
u Avoid dusty locations.
u Avoid electromagnetic noisy areas, such as locations close to power transformers or radio transmitters.
u Avoid temperatures below 32 Degrees Fahrenheit and over 122 Degrees Fahrenheit.
u Allow a clear view of the front panel LED indicators.
u Allow easy access to the front panel ports and the rear panel switches.
After choosing an appropriate location, you can install the switch on a desktop or in a rack.
Figure 4-1. Attaching self-adhesive feet for desktop installation
Rack Installation
Your switch comes with two rack mounting brackets. You can use these brackets to mount the switch on an EIA standard 19"
rack. Attach the brackets to the switch, using the screws provided.
Figure 4-2. Attaching the mount brackets for rack installation
Next, install the switch in the rack using the screws provided to attach the brackets to the rack.
Supplying Power
The Ethernet Switch is equipped with a universal switching power supply that accepts AC input voltages from 100 to 240VAC
and 50 to 60 Hz.
To supply power to your switch:
u Plug the connector of the power cord into the power port on the rear panel of your switch.
u Plug the other end of the power cord into an AC wall outlet.
u Set the power switch to ON and verify that the Power LED is lit. If it is not, check the following:
1. The power switch is in the ON position.
2. The power cord is properly connected to the wall outlet and to the power connection on the switch.
3. The wall outlet is functional.
Note: Network cable segments can be connected or disconnected from the switch while the power is on, without interrupting the
operation of the switch.
Connecting the Switch
You can connect your switch to network devices such as desktops and workgroups or to other hubs.
Before connecting your switch to a desktop or workgroup make sure that:
u The 10Base-T twisted pair Ethernet cabling is Category 3 or above.
u The 100Base-TX Fast Ethernet cabling is tested Category 5.
u The 100Base-FX fiber cabling is 62.5/125 micron multi-mode fiber.
u The 1000Base-SX/LX fiber cabling is 50/125, 62.5/125 or 9/125 micron multi-mode fiber.
Power Failure
In the event of an AC power failure, your Ethernet Switch should be turned off. When power is restored, you may turn the
Ethernet Switch back on.
To prevent costly equipment damage and downtime, please consider installing a surge suppression
device or a UPS (un-interrupted power supply).
Chapter 5
Module Installation and Removal
WARNING:
Before installing the Modules into a Switch, you must disconnect the Switch from the main
power supply.
Handling the Modules
The Module can be easily damaged by electrostatic discharge. To prevent damage, please observe the following:
u Do not remove Modules from their packaging until you are ready to install it into a Switch.
u Do not touch any of the pins, connections or components on the Modules.
u Handle the Modules only by its edges and front panel.
u Always wear an anti-static wristband connected to a suitable grounding point.
u Always store or transport Modules in appropriate anti-static packaging.
Module Setup and Installation
1. Ensure that the Switch is disconnected from the main power supply and that you are wearing an anti-static wrist-band
connected to a suitable grounding point.
2. Place the Switch on a flat surface. Using a small cross-bladed screwdriver, remove the blanking plate from the rear of the
Switch. Do not remove any other screws from the rear of the Switch.
3. Keep the blanking plate and screws in a safe place. If you remove the Module at any time, you must replace the blanking

interface.
c. Power up the Switch.
Installing 100Base-FX Modules
a. Remove the protective plastic covers from the fiber connectors on the Module.
b. Ensure that the Switch is powered up.
c. Plug the ST (or SC) connector on the fiber cable into the fiber socket on the Module.
d. Connect the other end of the fiber optic segment to an appropriate device fitted with a 100Mbps adapter.
Check the LED indicators on the front of the Switch to ensure that the Module is operating correctly.
Installing 1000Base-SX/LX Modules
a. Remove the protective plastic covers from the fiber connectors on the Module.
b. Ensure that the Switch is powered up.
c. Plug the SC connector on the fiber cable into the fiber socket on the Module.
d. Connect the other end of the fiber optic segment to an appropriate device fitted with a 1000Mbps adapter.
Check the LED indicators on the front of the Switch to ensure that the Module is operating correctly.
Removing the Modules
a. Ensure that the power supply and the backbone connection cables are disconnected from the Switch.
b. Place the Switch on a flat surface. Undo the two captive thumbscrews securing the Module into the Switch. Do not remove
any other screws from the rear of the Switch.
