Chapter 1 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 new 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 the 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 local area network. A

7
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
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 Switches were designed for easy installation and high
performance in an environment where traffic on the network
and the number of user increase continuously.
The Switches with their small, compact size were specifically
designed for small to middle workgroups. These Switches can
be installed where space is limited; moreover, they provide

8
immediate access to a rapidly growing network through a wide
range of user-reliable functions.
The Switches are 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 Switches are expandable by cascading two or more
switches together. As all ports support 200Mbps, the Switches
can be cascaded from any port and to any number of
switches.
The Switches are a perfect choice for site planning to upgrade
to Fast Ethernet in the future. Ethernet workgroups can
connect to the Switches now, and change adapters and hubs
anytime later without needing to change the Switches or
reconfigure the network.
The Switches 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 receive nodes to guarantee
against all possible packet loss.
The Switches are an unmanaged 10/100 Fast Ethernet Switch
that offers solutions in accelerating small Ethernet workgroup
bandwidth.
Other key features are:
•Uplink/ MDI-II (media dependent interface) port for Uplink
to another switch, hub or repeater.
•Store and forward switching scheme capability. As the
result of complete frame checking and error frame filtering,

9
this scheme prevents error packages from transmitting
among segments.
•N-Way 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 while the port’s receiving
buffer is full. Note that flow control is only available in
half-duplex mode.
•Data forwarding rate per port is at wire-speed for
100Mbps speed.
•Data forwarding rate per port is at wire-speed for 10Mbps
speed.
•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.
•Up to 1K active MAC address entry table per port with
self-learning and table-aging for the Switch

jack, which means you can connect the hub to a
device with a MDI-
X port using an ordinary
straight-
through cable, making a crossover cable
unnecessary.
Note:
1.The Hub is a power-required device, it means, the Hub
will not work until it is powered. If your networked PCs
will need to transmit data all the time, please consider
use an UPS (Uninterrupted Power Supply) for your Hub.
It will prevent you from network data loss.
2.In some area, installing a surge suppression device
may also help to protect your Hub from being damaged
by unregulated surge or current to the Hub or the power
adapter.

while Speed LED off for hookup to 10Mbps speed.
2. The FDX/COL indicator depends upon LAN card
capabilities for full-duplex or half-duplex.
Hub to Switch
A hub (10 or 100BASE-TX) can be connected to the Switch
via a two-pair Category 3, 4, 5 UTP/STP straight cable. The
connection is accomplished from the hub Uplink (MDI-II) port
to any of the Switch (MDI-X) ports: 1 –5/8 for the Switch.
A. 10BASE-T Hub
For a 10BASE-T hub, the Switch LED indicators should
light up as the following:
FDX /COL 100 LED indicator is OFF.
LINK/ACT LED indicator is light green.

16
B. 100BASE-TX Hub
For a 100BASE-TX hub, the Switch LED indicators
should light up as the following:
FDX /COL LED indicator is OFF.
LINK/ACT,100 Speed LED indicators are light green.
Hub without Uplink (MDI-II) port
If a hub is not equipped with an Uplink (MDI -II) port,
connection can be made using either straight cable 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 ports of the Switch to any port of the Hub.

17
Switch to Switches (other devices)
The Switch can be connected to another switch or other
devices (routers, bridges, etc.) via a two-pair Category 3, 4, 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 10Mbps
or 100Mbps (MDI-X) port of the other switch (switch B) or
other devices.
B Using crossover cable
When using crossover cable, this is done from any (MDI -X)
port of the Switch (Switch A) to any of the 10Mbps,
100Mbps (MDI-X) port of the other switch (switch B) or
other devices.
1. The LINK/ACT, 100 Speed LED indicators light green
for hookup to 100Mbps speed or only LINK/ACT light
green for hookup to 10Mbps speed.
2. The FDX 10/100,COL indicator depends upon LAN
card capabilities for full-duplex or 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
half-duplex.
