INTRODUCTION
This chapter describes the features of the 24-Port 10/100Mbps
Fast Ethernet Smart 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.
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. 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
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.
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.
VLAN (Virtual Local Area Network)
A VLAN is a group of end-stations that are not constrained by
their physical location and can communicate as if a common

5
broadcast domain, a LAN. The primary utility of using VLAN is
to reduce latency and need for routers, using faster switching
instead. Other VLAN utility include:
Security
Security is increased with the reduction of opportunity in
eavesdropping on a broadcast network because data will be
switched to only those confidential users within the VLAN.
Cost Reduction
VLAN can be used to create multiple broadcast domains, thus
eliminating the need of expensive routers.
Port-based (or port-group) VLAN is the common method of
implementing a VLAN, and is the one supplied in the Switch.
Each Switch port can belong from one to twenty four VLANs.

UNPACKING AND INSTALLATION
This chapter provides unpacking and setup information for the
Switch.
Unpacking
Open the shipping cartons of the Switch and carefully unpacks its
contents. The carton should contain the following items:
 One 24-Port 10/100Mbps Fast Ethernet Smart
Switch
 One AC power cord, suitable for your area’s
electrical power connections
 Four rubber feet to be used for shock cushioning
 Screws and two mounting brackets
 One console serial cable
 This User’s Guide
If any item is found missing or damaged, please contact your
local reseller for replacement.
Installation
The site where you install the Switch stack may greatly affect its
performance. When installing, consider the following pointers:

8
 Install the Switch in a fairly cool and dry place. See
Technical Specifications for the acceptable
temperature and humidity operating ranges.
 Install the Switch in a site free from strong
electromagnetic field generators (such as motors),
vibration, dust, and direct exposure to sunlight.
 Leave at least 10cm of space around the Switch for
ventilation.
 Install the Switch on a sturdy, level surface that can
support its weight, or in an EIA standard-size
equipment rack. For information on rack
installation, see the next section, Rack Mounting.
 When installing the Switch on a level surface, attach
the rubber feet to the bottom of each device. The
rubber feet cushion the Switch and protect the
Switch case from scratching.
Rack Mounting
The switch can be mounted in an EIA standard-size, 19-inch
rack, which can be placed in a wiring closet with other
equipment. Attach the mounting brackets at the switch’s side
panels (one on each side), and secure them with the provided
screws.

Connecting Network Cable
The Switch supports 10Mbps Ethernet or 100Mbps Fast Ethernet
and it runs both in half and full duplex mode.
These ports are Auto-MDIX type port. The Switch can auto
transform to MDI-II or MDI-X type, so you can make a
connection using a standard or crossover cable.

10
AC Power
The Switch requires AC power supply of 100~240V AC, 50~60
Hz. The Switch does not come with a Power ON/OFF switch, so
the Switch will automatically power on when it is connected to
an electrical outlet. The switch’s power supply will adjust to the
local power source automatically and may be turned on without
having any LAN segment cables connected.
IDENTIFYING EXTERNAL COMPONENTS
This chapter describes the front panel, rear panel, and LED
indicators of the Switch.
Front Panel
The figure below shows the front panels of the Switch.

LED Indicator
Comprehensive LED indicators display the status of the switch
and the network (see the LED Indicators chapter below).
10/100BASE-T Twisted-Pair Ports

11
These ports support network speeds of either 10Mbps or
100Mbps, and can operate in half- and full- duplex transfer
modes. These ports also support automatic MDI-II/MDI-X
crossover detection function gives true “plug and play”
capability.
Console Port
An RS-232 DCE console port is used to setup and manage the
Switch via a connection to a console terminal or PC using a
terminal emulation program (e.g. Windows HyperTerminal).
Rear Panel
AC Power Connector

CONFIGURATION
This Switch is a “smart” Switch. The programmable
administration parameters allow the Switch to operate more
effectively than unmanaged (dumb) switches. This chapter will
describe how to configure the Switch.
Console Port (RS-232 DCE)
The console configuration requires connecting a Workstation or a
PC running a terminal emulation program (such as
HyperTerminal, which comes with Microsoft Windows) to the
RS-232 DCE console port of the Switch.
Below is the console port configuration:
 Baud rate: 9,600
 Data width: 8 bits
 Parity: none
 Stop bits: 1
 Flow control: None
Make sure the terminal or PC you are using to make this
connection is configured to match these settings.
Configuring the Switch
The 24-Port 10/100Mbps Fast Ethernet Smart Switch has a
menu-driven console interface. The Switch can be configured
through the serial port. A network administrator can manage,
