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.

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

Connecting Network Cable  
The Switch supports 10Mbps Ethernet or 100Mbps Fast Ethernet  
and it runs both in half and full duplex modes.  
The Switch ports are Auto-MDI types. The Switch can  
automatically change all ports between MDI-II & MDI-X types  
alleviating any worry about using standard or crossover type  
cables.  
AC Power  
The Switch can be used with an AC power supply of 100~240V  
AC, 50~60 Hz. The Switch’s power supply will adjust to the  
local power source automatically and may be turned on without  
having any, or having some/all, LAN segment cables connected.

CONFIGURATION  
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:  
Baud rate:  
Data width:  
Parity:  
9,600  
8 bits

In the System screen, Factory Reset, Change Password, Confirm  
Password, Refresh Time, and Login Timeout, can be viewed and  
changed. System Uptime can’t be altered and is governed by the  
Switch.  
¾
File  
The Switch can have its configuration file uploaded or  
downloaded by using Upload Configuration or Download  
Configuration settings in the File setting screen.  
¾
Statistics  
In the Statistics menu screen, each port’s data transmit and  
receive status can be viewed, but not changed.  
18

First execute the terminal emulation program on the remote  
workstation, and turn on the Switch. When logging into the  
Switch, the following screen (Figure 10) prompt appears:  
Password:  
Figure 10. Login  
Insert the password into the blank space and then press Enter to  
log in to the Main Menu. If you are managing the Switch for the  
first time, you should input the factory default password “admin”  
to log in to the Switch. To change the password, first highlight  
System Change Password to input your new password, and then  
highlight Confirm Password to input your new password again  
for confirmation.

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.
