Gigabit slot2 1000BASE-FX Slot GIGABIT2

-13-

 10/100BASE-TX Fast Ethernet Switched Ports

Each switched port supports one connection to a LAN segments. Each
segment is an independent shared network in one collision-domain.
The connection can be to either a 10BASE-T or a 100BASE-TX device.

 MDI-X and MDI RJ-45 Connectors

MDI-X jack is labeled [X] normally to indicate the jack is designed
with internal crossover function. It allows a connection to an end
station using straight-through UTP cable. MDI RJ-45 connector is
provided for easy uplink via standard straight-through UTP to
other device that supports MDI-X RJ-45 connector. The following
table shows the pin assignments of MDI-X and MDI RJ-45
connector respectively:

PIN# MDI-X Jacks MDI Jack

1 Rx+ T x +
2 Rx- Tx­3 Tx+ Rx+
6 Tx- Rx-

4,5,7,8 NC NC

 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 infor­mation.

-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 follow­ing 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 receiv­ing 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 connec­tions. The maximum length and UTP cable categories used for the con­nections to a 10BASE-T device and 100BASE-TX device are:

CONNECTED DEVICE UTP CABLE USED & MAXIMUM LENGTH

10BASE-T device Cat. 3, 4, 5 UTP (100 meters)
100BASE-TX device Cat. 5 UTP (100 meters)

-16-

only operates on 1000M full-duplex mode. This function makes sure
the system operates with maximum performance when it is connected
to an auto-negotiation capable Gigabit Ethernet device.

Duplex Mode Full duplex

Fiber cable MM 50/125mm, 62.5/125mm recommended

Module Installation

1. Turn off the power to the switch unit.

2. Open the cover of Gigabit slot.

3. Insert the module into slot until it is seated properly.

4. Screw the module onto the chassis securely.

-18-

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 band­width. 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 al­lows 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 net­work. 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 net­work. 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 registra­tion 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 worksta­tions 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 func­tions, 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 pass­word. The factory default login name is admin and password is 123456.
If you desire, you can change this password after you log on.

-26-

5.4 Console Management

Any PC running Windows 95/98/ or NT can be used as a console. Use
the supplied RS232 cable and connect the console port to the COM port
of your console PC. Use Windows Hyper Terminal program to perform
this out-of-band management operations.

Factory default settings of the Console port

Baud rate : 115200, N, 8, 1, 1
Flow control : disabled

5.5 Web Management

Use any web browser with JAVA script support like Netscape Communi­cator 4.x or Microsoft Internet Explorer 4.0 or later on any platform. Con­nect to the managed unit using the IP address as URL address.

http://xxx.xxx.xxx.xxx

5.6 T elnet Management

Use Telnet software to perform the management operation. The most
convenient solution is using the built-in Telnet function in a Windows
95/98/ or NT PC. Enter into DOS window and invoke telnet command :

>telnet 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 opera­tion:

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.

-29-

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.

5.9 Support

This guide covers the basic information about the management func­tions supported by the managed switch. The detailed operation guides
for all management functions are available in the software operation
manual in the supplied CD-ROM. However, more features may be in­cluded into future new software upgrade. Contact the dealer where you
purchased the switch for the availability of new software and/or techni­cal support.
