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
2.3.1 Connecting end node or hub or switch
1. Place the Switch on a smooth surface or fasten the mounting brackets with the provided screws in a
standard 19” rack.
2. Connect switch or PC to one port of the Switch using Category 3/4/5 UTP/STP cabling.
3. Connect another switch or PC to the other port of Switch by following the same process as described in
Step2.
Notice:
Cable distance for Switch
The cable distance between Ethernet Switch and hub/PC should not exceed 100 meter for UTP/STP
cable, 2km for 62.5/125 and 50/125 fiber cable on 100Base-FX module, 220m for 62.5/125 fiber cable
and 500m for 50/125 fiber cable on 1000Base-SX module, 550m for 62.5/125 and 50/125 fiber cable
and 10km for 9/125 fiber cable on 1000Base-LX module.
Make sure the wiring is correct
It can be used Category 3/4/5 cable in 10 Mbps operation. To reliably operate your network at 100Mbps
and 1000Mbps, you must use an Unshielded Twisted-Pair (UTP) Category 5 cable, or better Data
Grade cabling. While a Category 3 or 4 cable may initially seem to work, it will soon cause data loss.
2.3.2 Connecting to Network Backbone or Server
Connect to the Gigabit Ethernet ports with Category 5 copper cable or fiber optic cable for uplinking to a
network backbone or network server. These ports operate at 1000Mbps in full-duplex mode. A valid
connection is indicated when the Link LED is light.
2.4 Terminal Setup
To configure the system, connect a 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:
5
♦ Baud : 38400
♦ Parity : None
♦ Data bits : 8
♦ Stop bits : 1
♦ Flow Control: none
Once the terminal has connected to the device, power on the device. The terminal will display that it is
loading the firmware. Then, the screen as below will show up:
Press “Enter” and input the password. The default password is “admin”.
2.5 IP Configuration
Once log on to the console, the “Command>” prompt will be shown. You can type “help” for all available
commands.
6
To setup the IP address, please use “sys set ip” command in the following format:
sys set ip <IP Address> <Subnet Mask> <Default Gateway>
For example, to configure the switch with the following IP settings:
IP Address: 192.168.0.2
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.254
Press input the following command and press <Enter> button:
sys set ip 192.168.0.2 255.255.255.0 192.168.0.254
If the IP is successful configured, the switch will automatically restart as the following window. You can
then configure the switch through its web interface.
7
3.WEB-BASED MANAGEMENT
3.1 Configuration
As well as the menu-driven system configuration program, the agent module provides an embedded
HTTP Web agent. This agent can be accessed by any computer on the network using a standard Web
browser (Internet Explorer 5.0 or above, or Netscape Navigator 4.5 or above).
Using the Web browser management interface you can configure a switch and view statistics to monitor
network activity. The Web interface also provides access to a range of SNMP management functions with
access to the switch's MIB and RMON database.
Prior to accessing the switch from a Web browser, be sure you have first performed the following tasks:
Configure it with a valid IP address, subnet mask, and default gateway using an out-of-band serial
connection.
For Internet Explorer 5.0 or later version user, please check the Java setting below before startup.
1. Click on Tools
2. Pick Internet Options
3. Select the Security tab
4. Select Local Intranet (click on the icon)
5. Click on Sites, click Advanced and add the IP address of the switch to the zone
6. Click on Custom Level
7. Scroll down and set Java Permissions to Custom
8. Press the Java Custom Settings button
9. Select the Edit Permissions tab
10. Set Run Unsigned Content to Enable
11. Press OK for all open dialog windows
NOTE
For IE5.0 or later version, if you can not find the Java option in point 7, please make sure your
Ethernet Explorer is installed with “Microsoft VM” JAVA virtual-machine plug-in.

3.2 Web Pages
To access the Web-browser interface you must first enter the password. The default password is "admin"
You will see the following screen comes out on the Web browser program:
Figure 3-1 : Password Screen
After the password is entered you will see the main menu screen.
Figure 3-2: The start up screen of SGSW-2402 Web Page
3.3 Port Config
This section allows you to have an easy access in configuring the ports of the management Switch. Notice
that the “Link state” option indicates “Up”. This shows that the port is connected to the network. It can
either be in “Up” (Connected) or “Down” (No connection) state.
9
Figure 3-3 The Port Config screen
Choose Port
You can choose a port either by clicking on the picture or by selecting it at the “Choose Port” field.
Speed/ Duplex
Speed/ Duplex is to select the operation mode of chosen port. The options are as:
‘Auto’: Auto negotiation
‘10Mbps HD’: 10 Base-T Half Duplex
‘10Mpbs FD’: 10Base-T Full Duplex
‘100Mpbs HD’: 100Base-TX Half Duplex
‘100Mbps FD’: 100Base-TX Full Duplex
Broadcast Rate Limit
This function sets broadcast limit to the desired rate for the specified port. It controls the reception of
broadcasting packets. The ranging for Broadcast rate limit varies from 0% to 100%. The higher the rate
is, the more broadcast packets can pass through the port. Rate is the percent of the traffic to allow before
throttling. That is, if you configure this value to 10% and current connected speed is 100M, Only 10M
broadcast data can pass through the port.
Port Priority
In a tagged VLAN application, you can specify the VLAN priority to expedite the VLAN traffic. There are
8 levels of priority, namely ‘0’, ‘1’, ‘2’, ‘3’, ‘4’, ‘5’, ‘6’ and ‘7’ in ascending priority.
Port VLAN ID
VLAN ID is the sequence number of a VLAN. The setting of the VLAN ID depends on ‘Belongs to
VLANs’ option. Thus, you should first configure the VLAN table through “VLAN config” option and then
specify this value.
Port State
Port state is for enabling or disabling the switch operation of the chosen port. If it is ‘enabled’, the chosen
port will receive and forward the packets, and learns the respective source MAC Addresses. If it is
‘disable’, the chosen port will not receive or forward any packets or learn source MAC Addresses.
It should be noted that if the cpu port (i.e. the switch port connected to the management workstation) is
disabled, without doubt, the communication link between user and the switch will not proceed further. It
10
is recommended to locate the link your PC used before disable the port state.
Flow Control
This feature enables or disables the Flow Control function of the port. Flow control can eliminate frame
loss by "blocking" traffic from end stations or segments connected directly to the switch when its buffers
fill. IEEE 802.3x flow control is used for full duplex. Note that flow control should not be used if a port is
connected to a hub.
3.4 VLAN Config
The management switch supports Virtual LAN, which logically group the connection into VLANs for traffic
isolation and security purposes. Both tagged and untagged based VLAN are supported with a total
maximum of 32 groups. Each VLAN group only forwards traffic within its member ports. For tagged VLAN,
each port can be a member of more than one VLAN group and it also supports priority with eight levels.
There is also provision for creating an untagged VLAN which support a connection with a legacy untagged
port. The VLAN configuration feature also allows you to build, delete and view tagged / untagged VLAN
groups and setting priority for tagged VLANs. The range of VID starts from 2 to 4094, as
default for Group 1.
VID 001 is the
Figure 3-4 The VLAN config Page
Setup Procedures
Step 1: Decide which Group you want to set for monitoring using mirror port. Click status column for that
particular group and key in the VLAN ID.
Step 2: Next, click on the dashed line’-‘ to select either “T” for Tagged or “U” for Untagged.
Step 3: Hit on “Apply” button after you satisfied with the setup. Click “Save” button to update the latest
configuration.
11
3.5 Trunk config
Port Trunking is the ability to group together several switch ports to increase the bandwidth between the
management switch and other switch. This is an inexpensive method to increase throughput between
switches (or to servers). We define the Port Trunking as the ability to group a set of ports into a single
logical link. The port trunk acts as single link between switches. It doesn’t create a loop even though it is
physically connected as such.
Figure 3-5 The Port Trunk config Page
Port Trunking Setup Procedures
Step 1: You can choose up to 4-port for Trunking by selecting ‘-‘ as “T”
Step 2: Click on “Apply” button to make the configuration effective.
Step 3: Click “Save” button to save the latest setting.
NOTE
Click “OK” button and select the ports again
If you select more than 4 ports for trunking, the following error message will appear:

The Aging Control Setup Screen
3.7 STP Config
STP Config provides two menu page to configure: STP Port and STP Bridge
3.7.1 STP Port
Bridge Port
This option shows the port of the bridge that connects to the root bridge.
Path Cost
This parameter is used by the STA algorithm to determine the best path between devices. Therefore,
lower values should be assigned to ports attached to faster media, and higher values assigned to
ports with slower media. (Path cost takes precedence over port priority.)
The default and recommended range is: Ethernet: 100 (50~600) Fast Ethernet: 19 (10~60) Gigabit
Ethernet: 4 (3~10). The allowed range is 0 - 65535.
Priority
Defines the priority for the use of a port in the Spanning Tree algorithm. If the path cost for all ports on
a switch are the same, the port with the highest priority (i.e., lowest value) will be configured as an
active link in the Spanning Tree. Where more than one port is assigned the highest priority, the port
with lowest numeric identifier will be enabled. The range is 0 - 255.
Setup Procedures
Step 1: Select any one of the ports, from 1 to 26, to connect to the root bridge.
Step 2: Key in the value for Path Cost.
Step 3: Set the priority level.

3.7.2 STP Bridge
This page lets you to have a clearer view in Spanning Tree parameters for whole switch.
Figure 3-6 The Spanning Tree Screen
Description of Parameters
STP State
When STP is enabled, it will dynamically detect network looping owing to mis-configuration of the
network topology. The redundant connectors will be disabled to avoid looping of packets. Looping
would often result in flooding of broadcast packets, halting the normal traffic.
Root Priority
Device priority is used in selecting the root device, root port, and designated port. The device with the
highest priority becomes the STA root device. However, if all devices have the same priority, the
device with the lowest MAC address will then become the root device.
Hello Time
The Hello time of the Spanning Tree field shows the number of seconds between the transmissions of
Spanning Tree protocol configuration messages.
Forward Delay
The Forward Delay field shows the number of seconds a port waits before changing from its Spanning
Tree Protocol learning and listening states to the forwarding state. This waiting is necessary so that
other switches on the network ensure no loop is formed before they allow other port to forward
packets.
Max Age
The maximum age time of the Spanning Tree shows the number of seconds the bridge waits without
receiving Spanning Tree Protocol configuration message before attempting a reconfiguration.
Setup Procedures
Step 1: Select Spanning Tree state option, either to enable or disable it.
Step 2: Set Root Priority from 0 s – 65535 s, and Hello Time from 1 s – 10 s.
Step 3: Key in the Forward Delay Time, Maximum Age and Hello Time.
14
Step 4: Click “Apply” button and save it if everything is OK.
The screen is divided into two sections. Current Spanning Tree Root section displays the
NOTE
read-only Spanning Tree settings for the current root switch and the parameters this switch is
to use when it becomes the root switch.
3.8 IGMP
Internet Group Management Protocol (IGMP) is an Internet protocol that provides a way for an
Internet computer to report its multicast group membership to adjacent routers. It allows the
management switch to forward multicast traffic intelligently. The switch "snoops" the IGMP query and
report messages and forwards traffic to only the ports that request the multicast traffic. This prevents
the switch from broadcasting the traffic to all ports and
Host Group Addresses
Host groups are identified by class D IP
addresses, i.e., those with "1110" as their
high-order four bits. Class D IP addresses,
i.e., those with "1111" as their high-order
four bits, are reserved for future addressing
modes.
In Internet standard "dotted decimal"
notation, host group addresses range from
224.0.0.0 to 239.255.255.255. The address
224.0.0.0 is guaranteed not to be assigned
to any group, and 224.0.0.1 is assigned to
the permanent group of all IP hosts
(including gateways). This is used to
address all multicast hosts on the directly
connected network. There is no multicast
address (or any other IP address) for all
hosts on the total Internet. The addresses of
other well-known, permanent groups are to
be published in "Assigned Numbers".
possibly affecting network performance.
The membership of a host group is dynamic - hosts may join
and leave groups at any time. There is no restriction on the
location or number of members in a host group. A host may
be a member of more than one group at a time. A host need
not be a member of a group to send datagrams to it.
Figure 3-7 The IGMP Screen page
3.8.1 IGMP Management
To activate IGMP function,
Step 1: Select “enabled” in the IGMP state field.
Step 2: Click on the radio button to select the version for IGMP.
Step 3: Hit on the “Apply” button and save your setting.
3.8.2 Definition on IGMP v1.0 and v2.0
For IGMP v1.0,
The Internet Group Management Protocol (IGMP v1.0) is used by IP hosts to report their host group
memberships to any immediately neighboring multicast routers. IGMP is an asymmetric protocol and
is specified here from the point of view of a host, rather than a multicast router.
NOTE
For IGMP v2.0,
IGMP v2.0 allows group membership termination to be quickly reported to the routing protocol, which is
important for high-bandwidth multicast groups and/or subnets with highly volatile group membership.
IGMPv1 has no leave mechanism. If a host no longer wants to receive the traffic, it simply
quits. If it is the last, the router will not have any answers to its query and will delete the GDA
for that subnet.
15
Multicast routers use IGMP v2.0 to learn which groups have members on each of their attached
physical networks. A multicast router keeps a list of multicast group memberships for each attached
network, and a timer for each membership. "Multicast group memberships" means the presence of at
least one member of a multicast group on a given attached network, not a list of all of the members.
When a host receives a General Query, it sets delay timers for each group (excluding the all-systems
group) of which it is a member on the interface from which it received the query.
When a router receives a Report, it adds the group being reported to the list of multicast group
memberships on the network on which it received the Report and sets the timer for the membership to
the [Group Membership Interval].
When a host joins a multicast group, it should immediately transmit an unsolicited Version 2
Membership Report for that group, in case it is the first member of that group on the network
When a host leaves a multicast group, if it was the last host to reply to a Query with a Membership Report
for that group, it SHOULD send a Leave Group message to the all-routers multicast group.
3.9 Stack
Stacking function is convenient for administrator to manage multiple switches by single IP.
Basically, you got to have min. 2 units,
Step 1: linking the switches by one category 5 or fiber cable.
Step 2: Choose either one management switch as Master switch, key in its IP number
(ex:203.70.249.152).
Step 3: Choose “Stack Config”.
Step 4: Choose “enable” of Stacking State, and “Save”.
Figure 3-8 The Stack screen page
16
Figure 3-9 The Stack screen page
Step 5: enter another unit management switch IP (ex:203.70.249.154) as Slave switch.
Step 6: choose “Stack Config”
Step 7: choose “Enable” of Stacking State, and “Save”.
Figure 3-10 The Stack screen page
17
NOTE
You can key in Master IP (ex:203.70.249.152), and choose “Stack Config”, then all the stack member list
will be displayed . You can then choose the switch you want to configure from the “Select switch to view”
list.
NOTE
Slave switch IP will be covered by Master one, and disappear temporarily. The slave IP
address can be the same as Master IP address. Thus, if master switch is malfunction, you
can still access the other switch by same IP address.
If you have difficulty on selecting another switch, you may be connecting to the slave switch’s
web, please close the browser window, use the “arp –d * ” DOS command to clear the ARP
table and then reopen the web.
Figure 3-11 The Stack screen page
3.10 SNMP
The management switch provides Simple Network Management Protocol (SNMP) over the UDP/IP
transport protocol as defined in RFC 1517 for network management applications.
To control the access of the system, a list of community entries is defined. Each community entry consists
of a community string and its access privilege. The Access privilege is either “Read Only” or “Read-Write”.
Only SNMP messages with correct community string and allowable operation are responded by the
system. The community list is configurable by all management operations. Only SNMP community with
“Read-Write” can view the whole list and make modifications. A “Read Only” community can only see its
own community entry.
NOTE
Trap messages are generated to report system events spontaneously as defined in RFC 1215. The
system can generate traps defined in the MIB it supports.
A list of “Trap Receivers” is defined in management as the target of each trap message. A Trap Receiver
In a stack environment, for master switch to know which switch you want to view and set by
SNMP, either the switches’ IP or community name must be different. Thus, if you have
stacked several switches by single IP, their community name must be different.
18
is a network node that deserves the trap message sent by management switch. A Trap Receiver entry
contains the IP address of the node and a community string that is included in the trap message. When an
event arises that requires a trap message to be sent, it is sent to every node listed in the Trap Receiver.
NOTE
If you are configuring slave switch’s SNMP settings, please reboot the switch after making
any configuration.

All MAC Addresses will be deleted immediately!
3.13 Mirror Port
3.13.1 Using Mirror Port to Monitor Traffic
This function allows you to set up a ‘mirror’ port of any specified port(s) or VLAN, such that you can
monitor the traffics of the monitored port(s) or VLAN without intervening them. In effect, the traffics on the
monitored port(s) VLAN are replicated on the mirror port that you can use a protocol analyzer to analyze
the traffic for specific problem.
21
Figure 3-15. Mirror Port Setup screen
3.13.2 Setup Procedures
Step 1: Select one Mirror Port.
Step 2: Click on the dashed line ‘-‘ on that particular port if you wan to select it as a Mirrored Member (T).
Step 3: Hit on “Apply” button after you are satisfied with the setup. Click “Save” button to update the latest
configuration.
3.14 Aging Control
Aging Control is for the aging of address entries in the switch’s forwarding table. If the aging control is
enabled, a learned address entry (not included the static entry) will be removed from the forwarding table
if there is no update within a pre-determined period (1 ~ 128 x 5 seconds). It is useful because the
resource of the forwarding table is limited. Enabling the aging control will not influence packets forwarding,
for that the packet is forwarded to all other ports when the destination MAC address cannot to found in the
forwarding table. If the aging control is disabled, all address entries will not be removes.
22
Figure 3-16 Aging Control screen
Aging Control Configuration Procedures
Step 1: Select “Enable” from the Aging Control option.
Step 2: Enter an integer in the entry, choosing from the range of 1 to 128, if the aging control is enabled.
If the aging control is disabled, this step can be skipped.
3.15 Address Search
Host Search is for searching a host by IP or MAC address on the whole switch, and getting the port
number to switch the host is connected. It is useful while configuring the VLAN. With this function, you can
easily detect the port at which a host is connected to and have an idea about which ports should be
included in a VLAN.
