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, 220m for 62.5/125 fiber cable and 500m for 50/125 fiber cable.
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. The following
sections describe the function of LEDs on the front panel

Switch. There are fixed 24x 10/100 Base-TX ports in Module 0, and another 2 slot ( module 1
and module 2 ) are used for expansion. In the following example, 1-port Gigabit 1000Base-SX
( LX ) Fiber Module, and 4-port 100Base-FX (ST) Fiber Module are installed into the Switch.
Figure 3-3 The Modules Page
3.5 Ports
Inside Ports page, you can enable/disable each port, configure Speed/Duplex for each port, and
assign VLAN ID.
The Port Management table shows the port status of all ports. You can also change some
properties of all ports in this table.
Figure 3-4 The Ports Page

- 11 -
3.6 Statistics
The Statistic page displays the detailed information about each port. You can compare and
evaluate throughput or other port parameters. All screen data is updated automatically and you
can also update the data manually.
Figure 3-5 The Statistics Page
3.7 VLAN
A VLAN ( Virtual LAN ) is a group of switch ports designated by the switch as belonging to the
same broadcast domain. This feature allows workgroup to be defined on the basis of their logical
location instead of their physical location, and does not require recalling.
If a broadcast packet is received from a port, it will forward this broadcast packet only to those
ports belonging to the same VLAN. VLAN classification of every packet is done in the following
way: If the packet is tagged with non-zero VLAN-id field then this is used as the VLAN id.
Otherwise the default VLAN id of the input port is used. You can assign a single switch port to
two or more VLANs.
The factory default VLAN is that all ports belong to the same VLAN group 1.
VLAN also enable you to configure port-based VLANs to help isolate broadcast traffic and
increase security.
Creating VLANs increases network flexibility by allowing you to reassign devices to
accommodate network moves, additions, and changes, eliminating the need to change physical
cabling.
This switch support up to 256 port-based 802.1Q-compatible virtual LANs (VLANs).

- 12 -
Figure 3-6 The VLAN Page
In the VLAN management window, you will see 2 VLANs in the page. To select a certain VLAN,
you can do the following:
Press ">>" button to display the next two VLANs
Press "<<" button to display the previous two VLANs
Press ">>|" button to display the last two VLANs
Press "|<<" button to display the first two VLANs
Enter the VLAN index in the "VLAN" edit box then press "Go to" button
You can add, edit and remove port members of each VLAN and then finally press "Apply"
button only once to configure the desired VLANs you want.
Note: if you want to set multiple VLANs, we suggest that you set Default VLAN ID for each port
first in Ports page.
3.8 TRUNK
Port trunking is the ability to group several 10/100Base-TX or 100Base-FX ports to increase the
bandwidth between this switch and another compatible switch. This is an inexpensive way to
increase bandwidth. We define port trunking as the ability to group set of ports (up to 8 ) within
the same module into a single logical link. The port trunk acts as a single link between switches.
Multiple trunks may be implemented in this switch, but only one trunk can be created within a
module.
Figure 3-7 The Trunk page

- 13 -
You can add, edit and remove port members of each trunk and then press "Apply" button after
you have finished configuring the trunks you need.
( Note: Make sure trunking ports are in the same VLAN group. )
3.9 STP (Spanning Tree Protocol)
Spanning tree is a link management protocol that provides path redundancy while preventing
undesirable loops in the network. For Layer 2 Ethernet network to function properly, only one
active path must exist between two stations.
The spanning-tree algorithm calculates the best loop-free path throughout a switched network.
STP forces redundant data paths into a standby (blocked) state. If a network segment in the
spanning tree fails and a redundant path exists, the spanning-tree algorithm recalculates the
spanning tree topology and activates the standby path.
Figure 3-8 The STP page
If you want to participate in spanning tree, have the "Enable Spanning Tree Protocol"
checkbox selected.
The Current Spanning Tree Root describes the unique root switch information for the instance
of spanning tree.
MAC Address: the MAC address of the root switch
Root Max Age: the amount of time (in seconds) protocol information received on a port is
stored by the root switch
Root Hello Time: how often the root switch broadcasts Hello message to other switches
Root Forward Delay: the amount of time a port will remain in the listening and learning states
before entering the forwarding state
Root Path Cost: the path cost to the root switch from this switch
Root Port: the port providing the best path from the switch to the root switch
The Spanning Tree Bridge Configuration describes this switch information in the spanning
tree.

- 14 -
3.10 Port Security
Port Security allows you to restrict specific MAC addresses to reside in some port. For example,
a dummy hub is attached to some port for extension, and you just only allow 2 users to access
this port at the same time, you can use the port security window to set the parameters.
Figure 3-9. The Port Security page
To restrict the number of MAC address to reside in a port, you must do the following :
Click the “ Enable “ checkbox for that port. IF the “ Enable “checkbox is uncheck, there is no
MAC address count restriction for that port.
Type the number in the “ Max Allowed MAC Address Count “ edit for that port. The upper
bound of this number is the “ Max Allowed MAC Address Count per port “
Press the “ Press “ button
The “ Used Count “ will tell you howmany MAC address residing in the corresponding port now.
Note : A trunked port is not allowed to enable the port security option.
3.11 Port Priority-802.1p
There are two priority queues ( high and low ) on each port. Each port arbitrates between two
transmit queues ( high and low priority ).
The arbitration uses weighted round-robin between the high and low priority queues, and you
can adjust this weight.

- 15 -
Figure 3-10. Port Priority – 802.1p page
Programmable Mapping of 802.1p to Internal Priority
The received packets with 802.1q tag are assigned priority according to a flexible and
programmable mapping of the 802.1p user-priority tag (3 bits, value from 0 to 7) to the internal
priority queue. The default is to assign a packet to high priority queue when the 802.1p
user-priority tag is 4 to 7, and to low priority queue when the 802.1p user-priority tag is 0 to 3.
Please check the corresponding mapping checkbox to assign a high priority or uncheck that to
assign a low priority.
3.12 Port Priority- Type of Service
Each port can parse the header of an incoming IPv4 header and identify the Type-Of-Service
byte (TOS field). This is extremely important with the deployment of Microsoft Windows 2000
and the emerging DiffServ standard, which marks Voice-Over-IP and other real-time traffic using
this field. This feature provides Layer 3 QoS.
Figure 3-11. Port Priority – Type of Service
If this function of a port is enabled, then the most significant 6 bits of the TOS (these 6 bits are
also known as the DiffServ Code Point "DSCP" field, value from 0 to 63) are used to assign a
priority to the packet received from this port. Please check the corresponding mapping checkbox
to assign a high priority or uncheck that to assign a low priority.

- 16 -
3.13 IGMP
Multicasting is used to support real-time applications such as video conferencing or streaming
audio. IGMP ( Internet Group Management Protocol ) allow you to query for any attached hosts
who want to receive a specific multicast service. The switch looks up the IP Multicast Group
used for this service and adds any port which received a similar request to that group. It then
propagates the service request on to any neighboring multicast switch to ensure that it will
continue to receive the multicast service.
Figure 3-12 The IGMP page
IF you want your switch to support multimedia and IP multicast, enable this option (default is
enabled). When this option is enabled, this switch only directs the multicast data packets to the
ports where needed, saving bandwidth. If " Forward with high priority " option is enabled, then
the IP multicast traffic will have a higher priority than other traffic.
3.14 Static Address
You can lock a certain MAC address ( associated with a host, ) to a certain port. Once a certain
MAC address is locked to a certain port, this MAC address will not receive any packets if it is
moved to another port.
Figure 3-13 The Static Address page

- 17 -
Static addresses are manually entered into the Static Address Table.
1. Enter the MAC address in the MAC Address field (ex. 00-00-00-00-00-01) and VLAN ID
(default is 1)
2. Select the Module and Port you want to associate with this entry with from the Port
drop-down box.
3. Click <<Add…<<.
4. Press “ Apply “ button.
Once a certain MAC address is locked to a certain port, this MAC address will not receive any
packets if it is moved to another port. Remove this entry from current static address table to
unlock this MAC address from that port, this MAC address is free again. Press “ Remove All “ to
delete all entries from static address table.
3.15 Broadcast Storm Filter
Storm Filter can avoid any flooded data packets. This feature prevents the bursts of broadcast
traffic. Excessive broadcast packets ( Broadcast Storms ) can be filtered in our managed switch
by enabling the "Broadcast Storm Filtering" option.
Figure 3-14 The Broadcast Storm Filter page
3.16 Port mirroring
Port Mirroring is to mirror traffic ( all frames ) from a specific resource port to a target port. This
help tracking down network errors or erroneous packet transfers without interrupting the flow of
data across the network.

- 18 -
3-15 The Port Mirroring page
If you want to monitor all receive and transmit packets of one port. You can do the following:
Choose the monitored port in " Mirror Source Port " choice box in the corresponding mirror
source module. Only one port can be monitored in one module at the same time.
Choose the corresponding target module, port in "Mirror Target Module" and "Mirror Target Port"
choice box.
Click the corresponding "Enabled" check box.
Press "Apply" button
3.17 IP Config
You can change the IP address, subnet mask and default gateway of the managed node. (You
can also do that from RS232 console). Enter the IP address, subnet mask and default gateway
in the corresponding edit box.
Figure 3-16 The IP Config page
If you want to change the user name or password for the managed node, the following steps is
needed:
Click the "Change Password" checkbox
Enter the user name in "Username" edit box

- 19 -
Enter the same password in "Password" and "Confirm Password" edit box
Press the "Apply" button
You should reboot system to let your settings take effect if you have changed one of the IP
address, subnet mask and default gateway.
3.18 SNMP
You can manage the Switch using third-party’s SNMP ( Simple Network Management Protocol )
agent. Access rights to the SNMP agent are controlled by community strings.
To set system name, system location and system contact, you can type the desired text string in
the corresponding edit box.
