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, 100BASETX (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.
1
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 and/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,
2
making it possible to expand your Fast Ethernet
network beyond the 100BASE-TX network’s 205-meter
network diameter limit.
Switches support both
traditional 10Mbps Ethernet and 100Mbps Fast
Ethernet. They are also ideal for bridging between the
existing 10Mbps networks and the 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 router costs more, is difficult to setup, and
maintenance intensive, all these 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 increases
continuously.
The Switch with their small, desktop size was
3
specifically designed for small to middle 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 highspeed servers for shared bandwidth 10Mbps or
100Mbps workgroups.
With the 200Mbps high
bandwidth (100Mbps full-duplex mode), any port can
provide workstations with a congestion -free data pipe
to access the server/workstation.
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
changing the Switch or reconfigure the network for
migrating to Fast Ethernet.
The Switch combine dynamic memory allocation with
store-and-forward switching scheme to ensure that the
buffer is effectively allocated for each port, while
4
controlling the data flow between transmit and receive
nodes to guarantee against all possible packet loss.
The Switch is an unmanaged 10/100Mbps Fast
Ethernet Switch that offers solutions for increasing
Ethernet workgroup bandwidth. The Switch’s other
key feature including the following:
?? Uplink/ MDI-II (media dependent interface)
port for uplinking to another switch, hub or
repeater.
?? Store and forward switching scheme. As the
result of complete frame checking and error
frame filtering, this scheme prevents error
packages from transmitting among segments.
?? NWay Auto-negotiation for each port. This
allows each port to auto-sense connection
speed (10/100Mbps), which provides automatic
and flexible connection for the network.
?? IEEE 802.3x flow control for full-duplex connections
and Back Pressure flow control for half-duplex
connections.
?? Data forwarding rate per port is at wire-speed
(100Mbps).
5
?? Data filtering rate eliminates all error
packets, runts, etc., per port at wire-speed for
100Mbps speed.
?? Up to 8K active MAC address entry table per
port with self-learning and table-aging.
?? 512 Kbytes RAM buffers per device.
?? Broadcast storm protection.

DC Power Jack: Power is supplied through an
external AC power adapter.
Check the technical
specification section for information about the AC
power input voltage.
Since the switch does not include a power switch,
plugging its power adapter into a power outlet will
immediately power on the device.
MDI-X Jacks: Use these jacks to connect
workstations to the Switch. These are MDI-X
(Medium-Dependent Interface, Cross-wired) jacks;
you can use ordinary straight-through twisted-pair
cables to connect network computers and network
9
servers to the Switch. If you need to connect another
device with an MDI-X jack, such as another hub or
Ethernet switch, you should use a crossover cable, or
make the connection using the MDI-II jack (described
below). For more information about crossover
connections.
Uplink Jack (MDI-II): Use this jack to connect other
hub or switch to the Switch. This is MDI-II (Mediumdependent Interface, straight-wired) jack, which
means you can connect the Switch to a device’s MDI-X
port using an ordinary straight-through cable.
LED Indicators

When connecting the Switch to a 10BASE-T hub, the
Switch’s port LED indicators should light up as the
following:
FDX/COL LED indicator is OFF.
Link/ACT LED indicator is light amber.
B. 100BASE-TX Hub
When connecting the Switch to a 100BASE-TX hub,
the Switch’s port LED indicators should light up as the
following:
FDX/COL LED indicator is OFF.
Link/ACT LED indicator is light green.
Hub without Uplink (MDI-II) port
If a hub is not equipped with an uplink (MDI-II) port,
the connection can be made using either straight cable
13
or crossover cable.
A. Using straight cable
When using straight cable, the connection can be made
from the uplink (MDI-II) port of the Switch to any port
of the Hub.
B. Using crossover cable
When using crossover cable, the connection can be
made from any port of the Switch to any port of the
Hub.
Switch to Switch (or other Ethernet device)
The Switch can be connected to another switch or
other Ethernet device (routers, bridges, etc.) via a twopair Category 5 UTP/STP straight or crossover cable.
A. Using straight cable
When using straight cable, this is done from the
uplink (MDI-II) port of the Switch (Switch A) to any of
the MDI-X port of the other switch (switch B) or other
device.
B. Using crossover cable
When using crossover cable, the connection is made
from any MDI-X port of the Switch (Switch A) to any of
14
the MDI-X port of the other switch (switch B) or other
device.
1.
The Link/ACT LED indicator lights green for
connecting to 100Mbps speed. The LED lights
amber for connecting to 10Mbps speed.
2.
The FDX/COL LED indicator lights green for
full-duplex connection. The LED remains off
for half-duplex connection.
Port Speed & Duplex Mode
After plugging the cable to a specific port, the system
uses auto-negotiation to determine the transmission
mode:
If the attached device does not support autonegotiation or has auto-negotiation disabled, an
auto-sensing process is initiated to select the proper
connection speed and the duplex -mode is set to halfduplex.
