Stack ports
There are two stack ports on the front panel. One is IN and the other is OUT. When
stacked, the IN port should connect to the other switch’s OUT port and the OUT port
should connect to other switch’s IN out. You can just use normal Cat 5 or better cable with
RJ-45 connector to stack. Only straight-through UTP/STP cable can be used. There is no
Duplex Mode issue and the maximum distance between first and last switch is 800m.
SWITCH ID
Each switch on a stack must have a unique switch ID. There are eight degrees (0~7) in
the rotary switch. The switch with least switch ID will become master switch and the
others become slave. If master switch is fail or disconnected to the switch by stack port,
the switch with least switch ID will become master.
Every device in the management stack should have a unique “Switch ID”. In the
meanwhile, a “Switch ID” which has been using by a device, reused by another, the
management stack will fail.
Reset button
At the middle of front panel, the reset button is designed for reboot the switch without turn
off and on the power.
10/100Mbps Ethernet ports
There are 24 10/100Mbps RJ-45 (copper) ports with one 100Mbps fiber optic slide-in slot.
The slot is shared with port 1 which means if a fiber module is installed in this slot, the first
RJ-45 port will be disabled. The following pictures show the available module for this
slot.

Console Port
The RS-232 console is an interface for connecting a terminal directly. Through the
console port, it provides rich diagnostic information includes network statistics, link status
and system setting. The operating mode of the console port is:
♦ DCE
♦ 9600 (Fix baud rate)
♦ n (No parity checking)
♦ 8 (8 Data bits)
♦ 1 (1 stop bit)
♦ None (No flow control)
You can use a normal RS-232 cable and connect to the console port on the device. After
the connection, you can run any terminal emulation program (Hyper Terminal, Winterm,
Telix, and so on) to enter the startup screen of the device.
Power Receptacle
For compatibility with electric service in most areas of the world, the switch’s power supply
automatically adjusts to line power in the range 100-240 VAC and 50-60 Hz.
Plug the female end of the power cord firmly into the receptacle on the rear panel of the
switch. Plug the other end of the power cord into an electric service outlet then the power
will be ready.
Power Notice:
1. The device is a power-required device, it means, it will not work till it is powered. If your
networks should active all the time, please consider using UPS (Uninterrupted Power
Supply) for your device. It will prevent you from network data loss or network downtime.
2. In some area, installing a surge suppression device may also help to protect your switch
from being damaged by unregulated surge or current to the Switch or the power
adapter.
2.3 Hardware Installation
This switch can be placed directly on your desktop, or mounted in a rack. If you install the
device in a normal-standalone standard, the switch is an managed Switch, and users can
immediately use most of the features simply by attaching the cables and turning the
power on. In this case, any managerial proceedings are effective only in the range of the
switch. After management stacking, you can enjoy the powerful management functions
and control the whole system.
Desktop Installation
For desktop installation, the switch needs to put on a clean, flat desk or table close to a
power outlet. Plug in all network cables and the power cord, then the system is ready.
Before installing the switch, you must ensure:
1. It is accessible and cables can be connected easily.
- 8 -
2. Cabling is away from:
w Sources of electrical noise such as radios, transmitters and broadband amplifiers
w Power lines and fluorescent lighting fixtures.
3. Keep water or moisture off.
4. Airflow around the unit and through the vents in the side of the case is great for heat
radiation (company recommend that you provide a minimum of 25 mm clearance).
To prolong the operational life of your units:
1. Never stack unit more than eight sets high if freestanding.
2. Do not place objects on top of any unit or stack.
3. Do not obstruct any vents at the sides of the case.
Rack-mount Installation
The switch may standalone, or may be mounted in a standard 19-inch equipment rack.
Rack mounting produces an orderly installation when you have a number of related
network devices. The switch is supplied with rack mounting brackets and screws. These
are used for rack mounting the unit.
Rack Mounting the Switch in the 19-inch rack:
1. Disconnect all cables from the switch before continuing.
2. Place the unit the right way up on a hard, flat surface with the front facing toward
you.
3. Locate a mounting bracket over the mounting holes on one side of the unit.
4. Insert the screws and fully tighten with a suitable screwdriver.
5. Repeat the two previous steps for the other side of the unit.
6. Insert the unit into the 19" rack and secure with suitable screws (not provided).
7. Reconnect all cables.
Installing Network Cables
Station Connections -
Refer to the wiring statement of the previous section; connect each station with correct
type of cables.
Switch-to-Switch Connections –
In making a switch-to-switch connection, use Gigabit ports to connect another switch or
backbone is strongly recommended. The Gigabit ports provide the fat pipe to the server or
backbone connectivity for boosting the total system performance. Refer to the wiring
statement of the previous section; connect each station to the switch with correct type of
cables.
Module Installation
The two slide-in slots on the rear panel are purposed for installing optional modules. They
can be used as a network backbone or connect to a server. Follow the steps as described
to install a module:
1. Power off the switch.
2. Removing the two screws on the face plate of slide-in slot with a flat-head
screwdriver.
- 9 -
3. Push the module gently into the slot along the slide tracks.
4. Ensuring that it firmly engages with the connector then tighten the screws to secure
the module.
CAUTION: The slide-in slots are not hot swappable, power off the switch before installing
modules.
2.4 Stack Installation
There are two RJ-45 ports on the front panel for proprietary management stack. Only
straight-through UTP/STP cable can be used.
Plug one end of the cable in the “IN” port and the other end to the ”OUT” port of next
device. Repeat the step for every device in the stack cluster, then ending at last switch.
NOTE:Before management stacking, be sure of every device uses a unique “SWITCH
ID”, or the management stack will not work. The switch with least SWITCH ID
will become Master. Only Master switch’s management interface (console,
telnet, web and SNMP) is accessible.
Please find the following picture for sample connection. Please note the stack port is for
management only. For data packets to be transmitted between switches, you will still
need to connect their network ports.
- 10 -
Chapter 3 CONSOLE AND TELNET MANAGEMENT
3.1 Connect To PC by RS-232 serial Cable
NOTE: If you have stacked several switches together, make sure you are working on
Master switch (switch with least Switch ID). Other slave switches’ management
interface allows only viewing the configuration by “guest” account.
To configure the system, connect the provided serial cable to a COM port on a PC or
notebook computer and to serial (console) port of the device. The console port of the
device is DCE already, so that you can connect the console port directly through PC
without the need of Null Modem.
A terminal program is required to make the software connection to the device. Windows'
Hyper Terminal program may be a good choice. It can be accessed from the Start menu.
Click START, then Programs, Accessories and then Hyper Terminal.
MS-DOS based terminal program such as PC-PLUS, PROCOMM, can also make the
connection with the device built-in software. The COM port should be configured as:
♦ Baud : 9600
♦ Parity : None
♦ Data bits : 8
♦ Stop bits : 1
♦ Flow Control : None
If you are using Windows 95/NT/98/2000/XP, launch “HyperTerminal”, create a new
connection, and adjust settings as below:
Please then power on the switch; launch the new terminal program you just set up. Press
“Enter” key, then login screen appears. Please check chapter 3.3 for detail on console
management.
3.2 Telnet
To access the switch through a Telnet session:
1. Be Sure of the switch is configured with an IP address and the switch is reachable
from a PC.
- 11 -
2. Start the Telnet program on a PC and connect to the switch.
The management interface is exactly the same with RS-232 console management except
the “root” privilege is not supported.
3.3 Main Menu
After you enter the switch’s console interface by RS-232 cable or telnet, the following
page is shown. Please enter username and password to access WGSW-2403.
There are three system default accounts for different privilege levels:
“root”: root can do any configuration includes changing password and enable/disable
management capability via console port. The default password of root is
“superuser”. Note that this account is not workable on telnet and web
management interface.
“admin” admin can do any configuration except changing password. The default
password of admin is “admin”.
“guest”: guest can view the whole switch information only, moreover, access to Web
management interface is not allowed. The default password is “guest”.
Main menu appears after successfully login WGSW-2403. To enter any of the submenus,
simply type the number after the command prompt. When select further options, you
may be asked for the device ID which you want to configure. Please just input the
SWITCH ID which you have configured on the switch front panel.

CHAPTER 4 WEB MANAGEMENT
4.1 Start A Web Browser Session
The Web Interface of WGSW-2403 is coded by Java Applet and running on the JavaTM
Virtual Machine (JVM) version 1.3.1 platform. You should configure the management
station with an IP address and subnet mask compatible with WGSW-2403 for accessing
it. Also, the management station should be well configured and connected to Internet for
automatically downloading (upgrading) the suitable JVM through Internet from
http://java.sun.com. Or you can download from
http://java.sun.com/j2se/1.3/download.html and manually install it.
Note: Usually the newer JavaTM Virtual Machine is not backward compatible. JVM version
1.3.1 is strongly recommended to ensure properly operation.
The default network configurations are as follows:
IP: 192.168.0.1
Subnet Mask:255.255.255.0
Default Gateway: 192.168.0.254
1. Activate a web browser and enter the IP address you have configured in the address
field. A screen pops up and asks for username/password. Use system default users

4.8 SNMP
Simple Network Management Protocol (SNMP) is a communication protocol for managing
devices on a network. It is commonly used for network administrators to communicate
with multiple devices (hub, switch, router ……) for configuring and monitoring while
convenient for troubleshooting but no miscellaneous platform consideration.
The built-in SNMP is an agent, which watches the status of it self. The Network
Management Station (A computer attached to network with SNMP management program
well installed) can be used to access it.
Community
A valid entry of Community String and IP Address is for authentication to login to the
SNMP agent for configuration. Moreover, the community capacity can up to 3 sets and
only by the way of specified IP address here will be allowed to access the agent. One
entry consist of IP address “0.0.0.0” will allow the ones who know the community string to
access the agent (with Read-Only access right) without limitation.
To Add a community
1. Input a name as a community string for authentication in the “Community String”
field (ex: administrator).
2. Enter the IP address in the “IP address” field you allow to access from (ex:

4.9 VLAN
The VLAN is a group of ports that may spread around the network but communicate as
though they belong to one subnet. By using VLAN, all ports can be reorganized into
separate broadcast domains for security reasons and reduce bandwidth occupation
instead of using routers to divide whole network into subnets. It produces cleaner network
environment by reducing broadcast traffic and simplify network management by allowing
you to move devices to another VLAN without changing physical connections. The
switch support 2 VLAN type: 802.1Q VLAN and Port Group VLAN.
802.1Q VLAN:
Before enabling 802.1Q VLAN, pay attention to:
w All ports are default to VLAN 1 and assigned PVID 1.
w Though you can configure VLAN group with VLAN ID from 1 to 4094. Due to
hardware’s restriction, the maximum PVID supported on this switch is 255.
VLAN Static List
This screen is used to Add / Remove / Modify VLAN and up to 255 groups is supported on
this switch. The VLAN groups that have been created are all listed here.
To create a new VLAN group
1. Specify the name for the new VLAN group (VLAN name is only used for
identification).
2. Enter a number (VLAN ID) for the new VLAN group. The VLAN ID can be set from
1 to 4094.
3. Check the “Active” box to activate the VLAN or leave it blank and activate it
afterward.
4. Click <<Add button to create the new VLAN.
- 27 -
To remove a VLAN group
1. Select a VLAN group you want to remove from the “Current” list.
2. Click Remove>> button to remove it.
Attention:
1. If a removed port is no longer belonged to any other group, it is temporarily
disabled because no one can communicate with it.
2. If one port’s PVID is equal to this VLAN ID, removing this VLAN group will not
allow until you change it.
To modify a VLAN group
1. Select a VLAN group you want to modify from the current list
2. Modify parameters in “New” column
3. Click Modify button to submit the new parameters
VLAN Static Table
This screen is used to Add/Remove member ports of a VLAN.
To add member port
1. Click the “VLAN ID” combo box and select a VLAN you want new ports to join in
2. Select ports (press Shift/Ctrl key for selecting multi ports) in the “Non-Member”
column
3. Click <<Add button to join selected ports in
To remove member port
1. Click the “VLAN ID” combo box and select a VLAN you want to remove ports
2. Select ports (with Shift/Ctrl key to select multi ports) in the “Member” column
3. Click Remove>> button to delete selected ports
NOTE:
1. If a removed port is no longer belonged to any other group, it is temporarily disabled
because no one can communicate with it.
2. The port which is assigned a PVID and the PVID is equal to VLAN ID, removing the
port will not allow until you change it.
- 28 -
VLAN Port Configuration
When the VLAN-enabled switch receives an untagged packet, the packet will be sent to
the port’s default VLAN according to the PVID (port VLAN ID) of the receiving port.
To change the PVID
1. Double click the “PVID” column of a port.
2. Input a new VLAN ID (1~255).
3. Press “Enter” to submit the value.
4. Click Apply button to apply it.
NOTE:
1. All the ports are default as members of VLAN 1 and assigned PVID 1.
2. Though you can configure a VLAN group with VLAN ID from 1 to 4094, the
supported PVID on this switch is only from 1 to 255.
3. The port which was assigned a PVID and the PVID is equal to VLAN ID, removing
the port will not allow until you change it.
4. Automatically, a port will join the VLAN of its PVID, and if the VLAN does not exist,
system will create it.
To Enable/Disable Ingress Filtering
When one packet comes in from Port X to VLAN Y, but Port X is not a member of VLAN Y:
Ingress Filter Enabled - The filter checks the packet and detects Port X does not
belong to the VLAN Y, the Ingress Filter discards the
packet.
Ingress Filter Disabled - All the packets destined to VLAN Y are all unobstructed.
Click the “Ingress Filtering” column of a port and select ‘Enable’ to activate Ingress Filter.
Port Group VLAN
The Port Group VLAN (Port-based VLAN) is concentrate on definite ports. The packets
forwarding policies are based on destination MAC addresses or related ports by voluntary
learning relationship of MAC addresses and its related ports.
- All Together
- 29 -
Click All Together button then all the ports of the switch will be added to VLAN
group 1.
- All Independent
Click All Independent button then all the ports will be divided into separated
subnets (totally 18 subnets).
Every port can belong to different Port Group VLANs simultaneously without limitation.
4.10 IGMP Snooping
Multicasting is widely used to support multi-media applications such as video
conferencing. The multicasting simply broadcasts its services to the group of a network
instead of establishing connections separately with every host that subscribed the
services. With no Multicast Filtering-aware switches, a multicast server may floods
broadcast-data overall the broadcast domain and wastes a lot of bandwidth.
The Internet Group Management Protocol (IGMP) snooping uses the protocol to make
switches join/leave multicast group and interacts switches to optimize the network
performance by monitoring the IGMP packets and forward to the ports containing
multicast hosts or switches. This will efficiently reduce the multicast traffic rather than
flooding overall network. IGMP snooping is more and more important especially when the
multi-media demand is booming.
NOTE: As IGMP Snooping only operates under 802.1Q VLAN mode, please change
VLAN mode from Port Group VLAN to 802.1Q VLAN before enabling IGMP
Snooping.
4.11 Port Aggregation
Port Aggregation (Port Trunk) is used to increase the bandwidth of a switch-to-switch
connection and backup. This switch provides 7 port aggregation groups, which consist of
4 ports and create bandwidth up to 800Mbps per group (the group 6 consists of 2 slide-in
slots and creates bandwidth up to 4Gbps) at full duplex mode. Check the box of
Aggregation Group in the Status Enable column and press “Apply” then the selected
Aggregation Group is activated.
- 30 -
However, before making connections between switches, pay attention to:
w The ports at both ends of a Port Aggregation connection must be configured as
Aggregation Ports.
w The ports at both ends of a Port Aggregation connection must have the same port
properties, including Speed, Duplex mode.
w All the ports of a Port Aggregation must be treated as an integer when added
to/deleted from a VLAN.
w Spanning Tree Algorithm (STA) treats all the ports of a Port Aggregation as an
integer.
w Before connecting cables between switches, enable the Pot Aggregation to avoid
looping.
w Before disabling Port Aggregation, remove the connecting cables between switches
to avoid looping.
w Both two slide-in slots should use the identical modules (two coppers/two fibers)
otherwise the Port Aggregation connection is invalid.
4.12 STA
The Spanning Tree Algorithm (STA) outlined in IEEE 802.1D can avoid network looping
but coexist with linking backup. This feature permits STA-aware switches interact with
each other. This can ensure only one route exists between any two devices on the
network. If looping is detected (maybe implements on purpose for linking backup), looping
ports will be blocked to discard additional route. If one using route fails, this Spanning
Tree Algorithm automatically releases the blocking port and establishes connection with
other devices.
Since a STA network has been established, all devices listen for Hello BPDUs (Bridge
Protocol Data Units) sent from the Root Bridge. After the Max Age maximum time is up,
the device supposes that the route to the Root Bridge is down. The devices initiate
negotiations with each other to reconfigure the network for a valid topology.

4.13 Priority
This switch supports IEEE802.1p CoS with 2-level priority. There are 8 traffic classes and
8 Service Rules in the Priority Map. When one packet carries with priority-tag, which has
specified a CoS (Class of Service) comes into the switch, the specified CoS tag will
determine what priority (Low/High) will it get according to the Priority Map in the switch.
The available Service Rules are:
- 34 -
FIFO The first in packet, the first out packet (No priority)
1：1 Send 1 high priority packet, then 1 low priority packet
2：1 Send 2 high priority packets, then 1 low priority packet
3：1 Send 3 high priority packets, then 1 low priority packet
4：1 Send 4 high priority packets, then 1 low priority packet
5：1 Send 5 high priority packets, then 1 low priority packet
6：1 Send 6 high priority packets, then 1 low priority packet
7：1 Send 7 high priority packets, then 1 low priority packet
