I NTRODUCTION
This chapter describes the features of the Switch and some
background information about Ethernet/Fast Ethernet switching
technology.
Fast Ethernet Technology
{xe " astEthernetTechnology”"}The growing importance of LANs
and the increasing complexity of desktop computing applications are
fueling the need for high performance networks. A number of highspeed LAN technologies have been proposed to provide greater
bandwidth and improve client/server response times. Among them,
100BASE-TX (Fast Ethernet){xe "“100Base-T”"} provides a nondisruptive, 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{xe " EEE802.3LAN”"} 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{xe "
SMA/CDEthernetprotocol”"}. Since the Switch is compatible with
all 10Mbps Ethernet environments, it provides a straightforward
upgrade and takes advantage of the existing investment in hardware,
software, and personnel training.

Switching Technology
{xe " witchingTechnology”"}Another approach to pushing beyond
the limits of Ethernet technology is the development of switching
technology. A switch{xe " witch”"} bridges and transmits Ethernet
packets at the MAC address level{xe " ACaddresslevel”"} of the
Ethernet protocol, 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{xe " egments”"}. Each segment
has its own bandwidth and it does not compete with others for
network transmission capacity.
A switch acts as a high-speed selective bridge between the individual
segments. The switch forwards traffic from origin segment to
destination segment, without interfering with any other segments. 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 uplinking Fast Ethernet 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. The switch
supports both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet,
which is also ideal for bridging between the existing 10Mbps
networks and the new 100Mbps networks.

LAN Switching technology{xe " witchingLANtechnology”"} is a
marked improvement over the previous generation of network bridges,
which were criticized by their higher latencies. Routers have also
been used to segment local area networks. But, the router expensive,
difficult to setup, and maintenance intensive, these make it relatively
impractical for the network. Switch, on the other hand, is less
expensive, easier to setup, and practically maintenance free, which
make it an ideal solution to today’s local area network congestion
problems.
Features
{xe " eatures”"}This high performance Switch was designed for a
network environment where traffic and the number of users increase
continuously.
The Switch, with their small, desktop size, was specifically design for
small to middle workgroups. It provides immediate access to a rapidly
growing network through a wide range of user-reliable functions.
The Switch is ideal for shared bandwidth 10Mbps or 100Mbps
workgroups with multiple high-speed servers. With the highest
bandwidth at 200Mbps (100Mbps full-duplex mode), each port can
provide workstation with congestion-free data-pipe for simultaneous
access to the server.
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 10Mbps network site that could be
upgraded to Fast Ethernet in the future. Ethernet workgroups can
connect to the Switch now, and change adapters and hubs anytime
5
later without changing the Switch or reconfiguring the network.
The Switch combines dynamic memory allocation with store-andforward switching method to ensure that the buffer is effectively
allocated for each port. It also controls the data flow between transmit
and receive nodes to guarantee against all possible packet loss.
This Switch is an unmanaged 10/100Mbps Fast Ethernet Switch that
offers solutions to increase Ethernet workgroup bandwidth. Other key

I NSTALLATION
This chapter provides unpacking and setup information for the Switch.
Unpacking
{xe " npacking”"}Open the shipping cartons and carefully unpacks
its contents. The carton should contain the following items:
u One the 16-port 10/100Mbps Fast Ethernet Switch
u One external power{xe "power"} adapter
u Four rubber feet to be used for shock cushioning

If any item is found missing or damaged, please contact your local
reseller for replacement.
Installation
The site where you install the Switch may greatly affect its
performance. When installing, consider the following pointers:
§
§
§
§
Install the Switch{xe "stack"} in a fairly cool and dry place. See
Technical Specification for the acceptable operating temperature
and humidity ranges.
Install the Switch{xe "stack"} in a site free from strong
electromagnetic source, vibration, dust, and direct sunlight.
Leave at least 10cm of space at the left and right hand side of the
Switch for ventilation.
Visually inspect the DC power jack and make sure that it is fully
secured to the power adapter.

Twisted-Pair Ports
These ports supports automatic MDI/MDIX crossover detection
function gives true ‘plug and play’ capability without the need of
confusing crossover cables or crossover ports.
With the Auto-MDI function, you just need to plug-in the network
cable to the hub directly and no need to care if the end node is NIC
(Network Interface Card) or switches and hubs.
DC Power Jack:
Power{ XE "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.
