INTRODUCTION
This chapter describes the features of the 16-Port 10/100Mbps
Fast Ethernet Smart Switch and some background
information about Ethernet/Fast Ethernet and
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

4
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

5
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 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
VLANs 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 sixteen VLAN.

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 16-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 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 hub stack may greatly affect its
performance. When installing, consider the
following pointers:
 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 at the front and rear of the
hub 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 .
 When installing the Switch on a level surface, attach
the rubber feet to the bottom of each device. The
rubber feet cushion the hub and protect the hub 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 front panel (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-MDI type port. The Switch can auto
transform to MDI-II or MDI-X type, so you can
just make an easy connection that without
worrying if you are using a standard or crossover
cable.
AC Power
The Switch can be used with AC power supply 100~240V AC,
50~60 Hz. The power switch is located at the rear
of the unit adjacent to the AC power connector
and the system fan. The switch’s power supply
will adjust to the local power source

11
automatically and may be turned on without
having any or all 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.

Ethernet 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
These ports support network speeds of either 10Mbps or
100Mbps, and can operate in half- and full- duplex transfer
modes. These ports also supports automatic MDI/MDIX
crossover detection function gives true “plug and play”
capability, just need to plug-in the network cable to the hub
directly and don’t care if the end node is NIC (Network Interface
Card) or switch and hub.

 Console Port
An RS-232 DCE console port is set up and managed the switch
via a connection to a console terminal or PC using
a terminal emulation program.
