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.
technologies have been proposed to provide greater bandwidth
and improve client/server response times. Among them,
A
number of high-speed LAN
100BASE-T (Fast Ethernet) provides a non-disruptive, smooth
evolution from the current 10BASE-T technology. The non-
disruptive and smooth evolutionary nature, and the dominant
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
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.
3
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.
4
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 in 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 features include:
¾
Security
Security is increased with the reduction of opportunity for
eavesdropping on a broadcast network because data will be
switched only to those users within the particular VLAN.
¾
Cost Reduction
VLANs can be used to create multiple broadcast domains, thus
eliminating the need for expensive routers.
Port-based (or port-group) VLAN is the common method of
implementing a VLAN, and is the one implimented in this Switch.
Each Switch port can belong to one or more of up to sixteen
VLANs.

Installation
The site where you install the hub stack may greatly affect its
performance. When installing, consider the following pointers:
¾
Install the Switch in a fairly cool and dry place. See
Technical Specifications for the acceptable temperature
and humidity operating ranges.
¾
Install the Switch in a site free from strong
electromagnetic field generators (such as motors),
vibration, dust, and direct exposure to sunlight.
¾
¾
Leave at least 10cm of space at the front and rear of 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 .
¾
When installing Switches on a level surface, attach the
rubber feet to the bottom of each device. The rubber
feet cushion the Switch and protect the case from
scratching.
8
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 each side), and secure them with the screws provided.
Figure 1. Combine the Switch with the provided screws
Then, use screws provided with the equipment rack to mount
each switch in the rack.
Figure 2. Mount the Switch in the rack

This Switch is an unmanaged, but “smart” Switch because
programmable administration parameters make it operate more
effectively than regular unmanaged (dumb) switches. This
chapter describes how to configure the Switch.
Console Port (RS-232 DCE)
The console configuration requires connecting a terminal, such as
a Workstation or a PC running a terminal emulation program
(such as HyperTerminal, which is automatically installed with
Microsoft Windows) to the RS-232 DCE console port of the
Switch.
The console port is set at the factory for the following
configuration:
„

Configuring Setup Menu
Note that there are two items, Port Configuration and VLAN, in
Setup menu as shown in Figure 12.
Figure 12. Setup Menu
¾
Port Configuration
In the Port Configuration menu (Figure 13), each port’s (inc. port
17: Fibre port) Speed, Flow Control, and QoS can be controlled.
Link Status is automatically determined by the Switch and can’t
be shifted.
21
Figure 13. Port Configuration
(1) Speed
There are five modes— Auto, 100M Full, 100M Half, 10M Full,
and 10M Half—for speed selections. To change the speed setting,
highlight Port and enter the port number to select the desired port,
next highlight Speed, click Enter, and use Space Bar to switch
between the five different options.
(2) Flow Control
This setting determines whether or not the Switch will be
handling flow control. To change the flow control setting,
highlight Port and enter the port number to select the desired port.
Set FlowCtrl to ON for avoiding data transfer overflow, or set it
to OFF where there is either no flow control, or this is handled
by other hardware/software management.
(3) QoS
If some ports need to have priority for data management transfer,
then QoS can be changed. QoS has two settings to choose from,
22
High and Low. The default setting for QoS on all ports is High.
To change the QoS setting, highlight Port and enter the port
number to select the desired port. Set QoS as required to
determine which ports will always transfer their data first.
(4) Link Status
This value is automatically determined by the Switch and can’t
be changed. If there is a valid connection to the Switch through
the indicated port, the Link Status will show the connection speed.
The status will be Down if there is no connection through that
port.
¾
VLAN (Virtual Local Area Network)
Grouping of individual ports into a small “virtual” network of
their own being independent of all other ports. To change the
VLAN, locate the port that needs to be set, select “V” for joining
the VLAN group and “-” for not joining. The default setting of
VLAN is shown as Figure 14.
Figure 14. VLAN Configuration
23
For example, there are five computers (PC1~PC5) connected to
the Switch’s port 1~5. They had been divided into two VLAN
groups: VLAN1 (PC1~PC4) and VLAN2 (PC2~PC5). There is
no way to connect PC1 and PC5, as shown in Figure 15. If PC1
has to connect to PC5, it should with it in the same VLAN.

Figure 15. There is no connection between PC1 and PC5
Using VLAN, the Switch can be divided into many independent
small switches. For example, in Figure 16, the Switch has been
divided into two VLAN groups. Both VLAN groups are
independent and there’s no link between these VLAN groups.
The Switch can be regarded as two smaller switches.
