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

2
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 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 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

5
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, this scheme prevents error
packages from transmitting among segments.
NWay 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.

6
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 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 4K active MAC address entry table per port
with self-learning and table-aging for 5-port model,
up to 8K active MAC address entry table per port
with self-learning and table-aging for 8-port model.
1 MB RAM buffer per device for 5-port model, 512
KB RAM buffer per device for 8-port model.

UNPACKING AND SETUP
This chapter provides unpacking and setup
information for the Switches.
Unpacking
Open the shipping cartons of the Switch and carefully
unpacks its contents. The carton should contain the
following items:
One 5-port or 8-port 10/100M NWay Fast Ethernet
Switch
One external power adapter
This User’s Guide
If any item is found missing or damaged, please
contact your local reseller for replacement.
Setup
The setup of the Switch can be performed using the
following steps:
The surface must support at least 1.5 Kg for the
Switch.

The power outlet should be within 1.82 meters (6
feet) of the Switch.
Visually inspect the DC power jack and make sure
that it is fully secured to the power adapter.
Make sure that there is proper heat dissipation
from and adequate ventilation around the Switch.
Do not place heavy objects on the Switch.

IDENTIFYING EXTERNAL COMPONENTS
This section identifies all the major external
components of the hub. Both the front and rear panels
are shown, followed by a description of each panel
feature. The indicator panel is described in detail in
the next chapter.
Front Panel
The figure below shows the front panels of the
switches.
5-port 10/100M NWay Fast Ethernet Switch
8-port 10/100M NWay Fast Ethernet Switch
LED Indicator Panel
Refer to the LED Indicator section for detailed
information about each of the hub’s LED
indicators.

10
Rear Panel
5-port 10/100M NWay Fast Ethernet Switch
8-port 10/100M NWay Fast Ethernet Switch
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 it on.
MDI-X Jacks: Use these jacks to connect stations
to the hub. These are MDI-X(Medium-Dependent
Interface, Cross-wired) jacks, which mean, you can
use ordinary straight-through twisted-pair cables

11
to connect user machines and servers to the hub
through them. If you need to connect another
device with an MDI-Xjack, such as another hub or
an 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(s) (MDI-II): Use this jack to connect
stations to the hub. This is MDI-II (Medium-
dependent Interface, straight-wired) jack, which
means you can connect the hub to a device with a
MDI-Xport using an ordinary straight-through
cable, making a crossover cable unnecessary.
