network applications have increased in speed, power and the ability to  
process information. To meet the demands of these more bandwidth-  
intensive applications, this switch device provides significant increase  
in performance for your Ethernet and Fast Ethernet network. The switch  
comes with high number of 10/100 Fast Ethernet switched ports, each  
capable of transferring information simultaneously at full wire speed to  
control and allocate the network bandwidth. It also provides two Gigabit  
Ethernet slots for migration to Gigabit network smoothly.  
The key features of the switch units are:  
High Port-count and High Bandwidth : Combining large number of 10/  
100Mbps-based Fast Ethernet switched ports and two Gigabit ports,  
the switches deliver a tremendous aggregated bandwidth for your net-  
work.  
Easy Migration : With 10BASE-T, 100BASE-T, 1000BASE-X support,  
the switch provides a non-disruptive and smooth migration path from  
Ethernet to Fast Ethernet, and even to Gigabit Ethernet network.  
Easy Installation : With the functions of auto-speed-sensing and  
auto-negotiation on each port, the switches support plug-and-play  
installation by default which eliminates configuration problems.  
Network Management : With the built-in SNMP and web manage-  
ment software agent, the switch provides network management func-  
tion for advanced applications. It allows you to control and monitor  
the switch remotely from anywhere in the network.

Gigabit Ethernet Slots  
Two Gigabit Ethernet slots are provided for Gigabit connections. Each  
can accommodate one Gigabit Ethernet module. A variety of optional  
modules is available for selection. Refer to section 3.3 for more infor-  
mation.  
-14-  
 
3.2 10/100BASE-TX Fast Ethernet Ports  
The switch can support connections to the following devices:  
10BASE-T or 10/100BASE-TX network cards  
10BASE-T hub ports  
100BASE-TX hub ports  
10/100BASE-TX dual speed hub ports  
10/100BASE-TX switch ports  
Auto-negotiation Capable  
The ports support auto-negotiation function when establishing a link  
connection with any auto-negotiation capable device. The connection  
speed and duplex mode are determined through the negotiation process  
with the connected device.  
Auto-speed-sensing  
When connecting to a non-auto-negotiation device, half duplex mode is  
used. However, the ports can auto-detect the connection speed.  
Manual Configuration  
The ports are configured to be enabled for auto-negotiation as factory  
default. However, it also can be changed and stick to one of the follow-  
ing configurations through network management operation:  
10M Half-duplex  
10M Full-duplex  
100M Half-duplex  
100M Full-duplex  
Trunking Function  
The ports are configured as normal data ports instead of trunking ports  
as factory default. In order to support trunking function, any port can be  
configured as a trunking port manually through network management  
operation. As configured, it is no longer a data port. For more details  
about trunking, refer to section 3.4.  
-15-  
 
Flow Control  
Half-duplex mode uses back pressure flow control to prevent the receiv-  
ing buffer from being overrun by data from a source node. Full-duplex  
mode uses the 802.3X flow control standard to prevent fast Physical  
Ports data traffic from overrunning slow data traffic.  
UTP Cable Connections  
When making a connection to another device using straight-through  
UTP cable, make sure MDI-X to MDI connection rule is followed. The  
following figure illustrates the pin assignments of a straight-through  
UTP and a crossover UTP cable:  
Straight-through and Crossover UTP Cable  
It is suggested to use straight-through UTP cables for all UTP connec-  
tions. The maximum length and UTP cable categories used for the con-  
nections to a 10BASE-T device and 100BASE-TX device are:

3.4 Making Trunk Connections  
Two switch units can be cascaded together through any regular switched  
data port on each unit when a port expansion is required. However, the  
transfer bandwidth between the two cascaded ports is limited to 200Mbps  
full duplex. To increase the bandwidth for the connection between two  
switch units, a trunking function is implemented on the switch unit for  
this purpose. Normal data ports can be configured optionally as trunking  
ports through the network management operation.  
Two or more trunking ports composes one trunk. Two switch units can  
be cascaded through one trunk. The aggregated bandwidth of one trunk  
can be up to 1.6Gbps, if 8 trunking ports are used for one trunk.  
Refer to the software operation manuals in the supplied CD-ROM for  
more information about how to configure a data port as a trunking port.  
The following figure illustrates an example of 4-port trunk connection  
between switch A and switch B. The Port 3, 4, 5 and 6 of switch A are  
configured as trunking ports and compose one trunk. The Port 5, 6, 7, and  
8 of switch B are configured as trunking ports and compose one trunk.  
The aggregated bandwidth of the trunk is 800Mbps.  
-19-  
 
Rules :  
1. One switch can be configured to have up to 4 trunks and each trunk  
can be composed of up to 8 trunking ports. All port members of one  
trunk must locate in same group, either in group [port 1-port 12] or in  
group [port 13 - port 24].  
2. One trunking port can only belong to one trunk.  
3. Only one trunk can exist between two switch units.  
4. Crossover UTP cables should be used at the same time for one trunk  
connection. The length of each cable can be up to 100 meters.  
5. When the switched data ports are enabled as trunking ports, they  
can only serve trunking function, but no other data function.  
6. Since the trunking is proprietary, the switches do not support trunk  
connection to other brand’s switches.  
The following figure illustrates a typical example of trunk connections  
between more than two switch units. Each trunk is a 2-port trunk.  
There are four trunks existing in this example. Each has 400Mbps band-  
width. The top switch is configured to have four trunks and is cascaded  
to four lower switch units.  
-20-  
 
3.5 Virtual LAN (VLAN)  
Each port of the switch unit connects to one individual LAN segment.  
There can be many Ethernet nodes located on each segment. The switch  
performs network data forwarding between different LAN segments. It al-  
lows Ethernet nodes located on different segments to communicate with  
each other. Basically, all Ethernet nodes are in one single LAN.  
A Virtual LAN (VALN) is a logical, independent workgroup within a net-  
work. The member in this workgroup communicate as if they are sharing  
the same physical LAN segment. VLANs are not limited by the hardware  
constraints that physically connect traditional LAN segments to a net-  
work. As a result, VLANs can define a network into multiple logical  
configurations.  
Because VLANs are self-contained, only the devices within the same  
VLAN can communicate with each other. If a device in one VLAN  
wants to communicate with a device in another VLAN, the traffic must  
go through a router. This would enhance the security of the network. In  
addition, broadcasts from servers within each group would go to the  
members of its own VLAN. This ensures that broadcasts cannot cause a  
network meltdown due to traffic volume.  
Implementation  
The VLAN implementation of this switch allows up to 256 VLANs in one  
switch. By using explicit or implicit VLAN tagging and the GARP/GVRP  
protocol (IEEE 802.1p and 802.1Q), VLANs may span across multiple  
switches. A MAC address can belong to multiple VLANs, and a switched  
port may be associated with multiple VLANs.  
Static Definitions of VLAN Membership  
The switch defines VLAN membership based on ports. Port based VLANs  
are organized by physical port numbers. The definitions are configured  
through the supported network management console.  
-21-  
 
Dynamic Learning of VLAN Membership  
While port based VLAN only defines static binding between a VLAN  
and its port members, the MAC address database associated with each  
port number and VLAN is learned and built up dynamically by the switch  
at run time.  
Dynamic Learning of Remote VLAN  
In addition to adding and deleting VLAN member ports through network  
management console software statically, the switch also supports GVRP  
(GARP VLAN Registration Protocol). GVRP allows for dynamic registra-  
tion of VLAN port numbers within a switch and across multiple switches.  
It is also used to communicate VLAN registration information to other  
VLAN-aware switches, so that a VLAN member can be covered by a wide  
range of switches in a network. GVRP allows both VLAN-aware worksta-  
tions and switches to issue and revoke VLAN memberships. The switches  
register and propagate VLAN membership to all ports belonging to the  
active topology of the VLAN.  
VLAN Configuration  
The switch currently provides a Local/Remote Management Console  
Interface for VLAN configuration and management. An SNMP-based  
VLAN MIB is also provided. Combining the hardware and software func-  
tions, the switch supports Intra-VLAN Communication and Inter-VLAN  
Communication.  
-22-  
 
4. LED Indicators

5.3 Setting IP Address  
Before performing any management operation over network, the most  
important thing is to learn the detailed information about the TCP/IP  
network where the managed unit is located. The information includes the  
network address, subnet mask, broadcast IP, IP of the default router. The  
second thing is to assign an IP address to the managed unit when it is  
received for the installation. A unique IP address is used to identify each  
managed device from others. No factory default IP address is assigned.  
Assign a unique IP address to the managed switch using direct console  
management before performing any in-band management operation.  
When you log on to the switch console port for the first time, a sign-on  
string appears and you are prompted for a console login name and pass-  
word. The factory default login name is admin and password is 123456.  
If you desire, you can change this password after you log on.

>t e l ne t xxx. xxx. xxx. xxx  
to connect to the managed switch. The specified xxx.xxx.xxx.xxx is the IP  
address of the managed switch.  
-28-  
 
5.7 SNMP and RMON Management  
SNMP management and RMON activities are performed at a network  
management station running SNMP network management application  
manager software with graphical user interface.  
The switch serves as an SNMP agent and provides RMON capabilities  
that allows network administrators to set parameters and view statistical  
counters defined in the MIB-II, Bridge MIB, private MIB and RMON  
MIB.  
The supported MIBs are available in the supplied CD-ROM of the switch.  
Use the SNMP management application software to compile the MIB file  
first before performing any management operation.  
5.8 Software Upgrade  
The device supports a Software Upgrade feature through TFTP protocol  
and Kermit protocol. TFTP file transfer functions allow you to perform  
software upgrade over network and Kermit file transfer functions allow  
you to perform software upgrade via console port.  
If you select File transfer command from the Advanced Management  
screen, specify the following information for software upgrade opera-  
tion:  
File name : file name of the new software version  
IP address : from where the software upgrade will be obtained. The ad-  
dress consists of numbers separated by periods. For example: 129.32.0.11  
After you finish the upgrade operation, reboot the switch using the  
supported command within the console or telnet.

Note: The TFTP protocol is used to download updated software to the  
switch. A VLAN with the proper IP address and routing path to the TFTP  
server must be configured for the switch to access the specified TFTP  
server. TFTP is an embedded function supported in the DOS window of  
any Windows NT system.  
Contact your dealer for any new available software version.
