INTRODUCTION
This chapter describes the features of the Switch and some
background information about Ethernet/Fast Ethernet
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 have been proposed to provide greater
bandwidth and improve client/server response times. Among
them, 100BASE-T (Fast Ethernet) provides a non-disruptive,
smooth evolution from the current 10BASE-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. Some of the 100Mbps Fast Ethernet products
(10/100Mbps dual-speed) are compatible with 10Mbps
Ethernet environments; they provide a straightforward upgrade
and take 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 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
dividing a local area network into different segments, which
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, without interfering with any
other segments, automatically forwards traffic that needs to go
from one segment to another. By doing this the total network
capacity is multiplied, while still 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 “two-
repeater 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 100BASE-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 a marked improvement over the

6
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, the
setup and maintenance required make routers relatively
impractical. Today, switches are an ideal solution to most
kinds of local area network 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 small, compact size was specifically designed for
small to mid size workgroups. This Switch can be installed where
space is limited; moreover, they provide immediate access to a rapidly
growing network through a wide range of user-reliable functions.
The Switch is ideal for deployment with multiple high-speed 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. As 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 site planning to upgrade 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 Switches or reconfigure the network.
The Switch combine dynamic memory allocation with store-and-
forward switching to ensure that the buffer is effectively allocated for
each port, while controlling the data flow between the transmit and

7
receive nodes to guarantee against all possible packet loss.
The Switch is an unmanaged 10/100 Fast Ethernet Switch that offers
solutions in increasing small Ethernet/Fast Ethernet workgroup
bandwidth. Other key features are:
?? 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-MDI function supports automatic MDI/MDIX crossover
detection function gives true ‘plug and play’ capability without
the need of confusing crossover cables or crossover ports.
?? Auto-negotiation for any port. This allows for auto-sensing of
speed (10/100Mbps) thereby providing you with automatic and
flexible solutions in your network connections.
?? Flow control for any port. This minimizes dropped packets by
sending out collision signals when the port’s receiving buffer is
full. Note that flow control is only available in half duplex
mode.
?? Data filtering rate eliminates all error packets, runts, etc., per
port at wire-speed for 100Mbps speed.
?? Data filtering rate eliminates all error packets, runts, etc., per
port at wire-speed for 10Mbps speed.

DC Power Jack: Power is supplied through an external
AC/DC power adapter. Check the technical specification
section for information about the DC power input voltage.
Since the switch does not include a power on/off switch,
plugging its power adapter into a power outlet will
immediately power on the Switch.
Auto MDI-X Jacks:
These ports support automatic MDI-II/MDI-X crossover
detection function, gives the Switch true ‘plug and play’
capability.
With the Auto-MDI function, you just connect the network
cable to the port and there is no need to worry about if the end
node is NIC (Network Interface Card) or switch or hub.

CONNECTING THE SWITCH
This chapter describes how to connect the Switch to your Fast
Ethernet network.
PC to Switch
You can connect a PC to the Switch via a two-pair
Category 3, 4, 5 UTP/STP cable. You can connect the PC
(equipped with a RJ-45 10/100Mbps jack) to any of the
ports. When connecting PC to the Switch, the Switch’s Port
LED indicator will light according to the network adapter’s
connection speed. If the port LED indicator does not light
after making a proper connection, check the PC network
card, the cable, and the Switch’s functionality.
Hub to Switch
A hub (10BASE-T or 100BASE-TX) can be connected to the
Switch via a two-pair Category 3, 4, 5 UTP/STP cable (use
Category 5 for 100Mbps connection). The connection is
accomplished from the any RJ-45 port on the hub to any RJ-45
port on the Switch. After connecting the hub to the Switch, the
Switch’s Port LED indicator will light according to the hub’s
connection speed. If the port LED indicator does not light after
making a proper connection, check the hub, the cable, and the
Switch’s functionality. Each port on the Switch has auto-MDI
function; you can make the connection using crossover or
straight through cable with uplink port or regular port from the
hub.

14
Switch to switch (or other Ethernet devices)
You can connect a switch or other Ethernet devices (10BASE-
T or 100BASE-TX) to this Switch via a two-pair Category 3, 4,
5 UTP/STP cable (use Category 5 for 100Mbps connection).
The connection is accomplished from the any RJ-45 port on the
device to any RJ-45 port on the Switch. After connecting the
hub to the Switch, the Switch’s Port LED indicator will light
according to the hub’s connection speed. If the port LED
indicator does not light after making a proper connection,
check the device, the cable, and the Switch’s functionality.
Each port on the Switch has auto-MDI function; you can make
the connection using crossover or straight through cable with
uplink port or regular port from the device.
Port Speed & Duplex Mode
After a connection is made the Switch uses auto-negotiation to
determine the transmission mode for this 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 half-
duplex.
Note: Only the 5-port model has Full-Duplex LED indicators.
