The 24 electrical ports support the 10/100 Mbps Ethernet IEEE 802.3 protocol, and auto-
negotiating and auto-MDI/MDIX features are provided for simplicity and ease of installation. 2 ports
are 10/100/1000 configurable for copper or fiber media for use with multimode or single mode optical
fiber, selected by optional SFP modules. These network managed layer 2 switches are optically
(1000 BASE-FX) and electrically compatible with any IEEE 802.3 compliant Ethernet devices. Plug-
and-play design ensures ease of installation, and no electrical or optical adjustments are ever
required. The CNGE2FE24MS incorporates LED indicators for monitoring the operating status of the
managed switch and network. These units are rack mountable.

Use four twisted-pair, Category 5e or above cabling for RJ45 port connection. The
cable between the switch and the link partner (switch, hub, workstation, etc.) must be
less than 100 meters (328 ft.) long.
Fiber segment using a small form-factor pluggable, a single-mode connector can be
applied to standard (such as 9/125 µm, 9.5/125 µm, or 10/125 µm) single-mode fiber
cable. Fiber spans are dependent on SFP used.
Fiber segment using a small form-factor pluggable, a multi-mode connector can be
applied to standard (such as 50 or 62.5/125 µm) multi-mode fiber cable. User can
connect two devices up to 2km distances.

Desktop Installation
Set the Switch on a sufficiently large flat space with a power outlet nearby. The surface
where you put your switch should be clean, smooth, level and sturdy.
Make sure there is enough clearance around the Switch to allow attachment of cables,
power cord and allow air circulation.
Attaching Rubber Feet
A. Make sure mounting surface on the bottom of the Switch is grease and dust free.
B. Remove adhesive backing from your Rubber Feet.
C. Apply the Rubber Feet to each corner on the bottom of the Switch. These footpads
can prevent the Switch from shock/vibration.
Attaching Rubber Feet to each corner on the bottom of the Switch
Rack-mounted Installation
The Switch comes with a rack-mounted kit and can be mounted in an EIA standard size,
19-inch Rack. It can be placed in a wiring closet with other equipment.
17
Perform the following steps to rack-mount the switch:
A. Position one plate to align with the holes on one side of the Switch and secure it with
the smaller plate screws. Then, attach the remaining plate to the other side of the
Switch.
Attach mounting plates with screws
B. After attaching both mounting plates, position the Switch in the rack by lining up the
holes in the plates with the appropriate holes on the rack. Secure the Switch to the
rack with a screwdriver and the rack-mounting screws.
Mount the Switch in an EIA standard 19-inch Rack
Note: For proper ventilation, allows about at least 4 inches (10 cm) of clearance on the
front and 3.4 inches (8 cm) on the back of the Switch. This is especially important for
enclosed rack installation.
18
Network Application
This segment provides the samples to help user have more actual idea of industrial
switch application. For the sample applications of the industrial switch, see the figures
below.
19
X-Ring Application
The industrial switch supports the X-Ring protocol that can help the network system to
recover from network connection failure within 20ms or less, and make the network
system more reliable. The X-Ring algorithm is similar to Spanning Tree Protocol (STP)
and Rapid STP (RSTP) algorithm but its recovery time is less than STP/RSTP. The figure
below is a sample of X-Ring application.
20
Couple Ring Application
In the network, it may have more than one X-Ring group. Using the coupling ring function
can connect each X-Ring for the redundant backup. It can ensure the transmissions
between two ring groups not to fail. The following figure is a sample of coupling ring
application.
21
Dual Homing Application
Dual Homing function is to prevent the connection loss from between X-Ring group and
upper level/core switch. Assign two ports to be the Dual Homing port that is backup port
in the X-Ring group. The Dual Homing function only works when the X-Ring function is
active. Each X-Ring group only has one Dual Homing port.
[NOTE] In Dual Homing application architecture, the upper level switches need to enable
the Rapid Spanning Tree protocol.
22
Console Management
Connecting to the Console Port
Use the supplied RS-232 cable to connect between a terminal/PC and the console port.
The terminal or PC to being connected must support the terminal emulation program.
Connecting the switch to a terminal via RS-232 cable
Login in the Console Interface
When the connection between Switch and PC is ready, turn on the PC and run a terminal
emulation program or Hyper Terminal and configure its communication parameters to
match the following default characteristics of the console port:
Baud Rate: 9600 bps
Data Bits: 8
Parity: none
Stop Bit: 1

Web-Based Management
This section introduces the configuration and functions of the Web-Based management.
About Web-based Management
There is an embedded HTML web site residing in flash memory on CPU board of the
switch, which offers advanced management features and allows users to manage the
switch from anywhere on the network through a standard browser such as Microsoft
Internet Explorer.
The Web-Based Management supports Internet Explorer 6.0 or later version. And, it is
applied for Java Applets for reducing network bandwidth consumption, enhance access
speed and present an easy viewing screen.
Preparing for Web Management

DHCP Server – System configuration
DHCP is the abbreviation of Dynamic Host Configuration Protocol that is a protocol for
assigning dynamic IP addresses to devices on a network. With dynamic addressing, a
device can have a different IP address every time it connects to the network. In some
systems, the device's IP address can even change while it is still connected. DHCP also
supports a mix of static and dynamic IP addresses. Dynamic addressing simplifies
network administration because the software keeps track of IP addresses rather than
requiring an administrator to manage the task. This means that a new computer can be
added to a network without the hassle of manually assigning it a unique IP address.
The system provides the DHCP server function. Enable the DHCP server function, the
switch system will be a DHCP server.
DHCP Server: Enable or Disable the DHCP Server function. Enable—the switch will
be the DHCP server on your local network.
Low IP Address: Type in an IP address. Low IP address is the beginning of the

2. State: Current port status. The port can be set to disable or enable mode. If the port
state is set as ‘Disable’, it will not receive or transmit any packet.
3. Negotiation: Auto and Force. Being set as Auto, the speed and duplex mode are
negotiated automatically. When you set it as Force, you have to assign the speed
and duplex mode manually.
4. Speed: It is available for selecting when the Negotiation column is set as Force.
When the Negotiation column is set as Auto, this column is read only.
5. Duplex: It is available for selecting when the Negotiation column is set as Force.
When the Negotiation column is set as Auto, this column is read only.
6. Flow Control: Set flow control function as Enable or Disable. When enabled, once

Port Trunk
Port trunking is the combination of several ports or network cables to expand the
connection speed beyond the limits of any one single port or network cable. Link
Aggregation Control Protocol (LACP), which is a protocol running on layer 2, provides a
standardized means in accordance with IEEE 802.3ad to bundle several physical ports
together to form a single logical channel. All the ports within the logical channel or so-
called logical aggregator work at the same connection speed and LACP operation
requires full-duplex mode.
Aggregator setting
System Priority: A value that is used to identify the active LACP. The switch with
the lowest value has the highest priority and is selected as the active LACP peer of
the trunk group.
Group ID: There are 13 trunk groups to be selected. Assign the "Group ID" to the
trunk group.
LACP: When enabled, the trunk group is using LACP. A port that joins an LACP
trunk group has to make an agreement with its member ports first. Please notice that
a trunk group, including member ports split between two switches, has to enable the
LACP function of the two switches. When disabled, the trunk group is a static trunk
group. The advantage of having the LACP disabled is that a port joins the trunk
group without any handshaking with its member ports; but member ports won’t know
that they should be aggregated together to form a logic trunk group.
Work ports: This column field allows the user to type in the total number of active
port up to four. With LACP static trunk group, e.g. you assign four ports to be the
members of a trunk group whose work ports column field is set as two; the exceed
ports are standby/redundant ports and can be aggregated if working ports fail. If it is
a static trunk group (non-LACP), the number of work ports must equal the total
number of group member ports.
57
Select the ports to join the trunk group. The system allows a maximum of four ports
to be aggregated in a trunk group. Click and the ports focused in the
right side will be shifted to the left side. To remove unwanted ports, select the ports

State Activity
Having set up the LACP aggregator on the tab of Aggregator Setting, you can configure
the state activity for the members of the LACP trunk group. You can tick or cancel the
checkbox beside the state display. When you remove the tick mark to the port and click
, the port state activity will change to Passive.
Active: The port automatically sends LACP protocol packets.
Passive: The port does not automatically send LACP protocol packets, and
responds only if it receives LACP protocol packets from the opposite device.
[NOTE]
1. A link having either two active LACP nodes or one active node can
perform dynamic LACP trunk.
2. A link having two passive LACP nodes will not perform dynamic
LACP trunk because both ports are waiting for an LACP protocol
packet from the opposite device.

Port Mirroring
The Port mirroring is a method for monitoring traffic in switched networks. Traffic through
ports can be monitored by one specific port, which means traffic goes in or out
Monitored (source) port will be duplicated into Analysis (destination) port.
Port Trunk – Port Mirroring interface
Mode: Choose the type of being monitored packets. RX means only the received
packets of the monitored port will be copied and sent to the analysis port. TX means
only the transmitted packets of the monitored port will be copied and sent to the
analysis port. Both RX/TX means both received & transmitted packets of the
monitored port will be copied and sent to the analysis port.
Analysis Port: There is only one port can be selected to be the analysis (destination)
port for monitoring both RX and TX traffic which come from the source port. Users
can connect the analysis port to LAN analyzer or Netxray.
Monitored Port: Choose a port number to be monitored. Only one port can be
monitored during the monitoring process.
And then, click .
62
Rate Limiting
All the ports support packet ingress and egress rate control. For example, assume the
wire speed of port 1 is 100Mbps; users can set its effective egress rate as 2Mbps,
ingress rate as 1Mbps. The switch performs the ingress rate by packet counter to meet
the specified rate.
Inrate: Enter the port effective ingress rate (The default value is “0”).
OutRate: Enter the port effective egress rate (The default value is “0”).
The rate range for port 1 to 24 is from 1 to 100 Mbps and the rate range for port 25, 26 is
from 1 to 1000 Mbps. The zero means disabled.
Rate Limiting interface
63
VLAN configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain,
which would allow you to isolate network traffic, so only the members of the same VLAN
will receive traffic from the ones of the same VLAN. Basically, creating a VLAN from a
switch is logically equivalent of reconnecting a group of network devices to another Layer
2 switch. However, all the network devices are still plugged into the same switch
physically.
The switch supports Port-based and 802.1Q (tagged-based) VLAN. The default
configuration of VLAN operation mode is Disable.
VLAN Configuration interface
VLAN configuration - Port-based VLAN
Packets can go among only members of the same VLAN group. Note all unselected ports
are treated as belonging to another single VLAN. If the port-based VLAN enabled, the
VLAN-tagging is ignored.
64
In order for an end station to send packets to different VLAN groups, it itself has to be
either capable of tagging packets it sends with VLAN tags or attached to a VLAN-aware
bridge that is capable of classifying and tagging the packet with different VLAN ID based
on not only default PVID but also other information about the packet, such as the protocol.

[NOTE]
Remember to execute the “Save Configuration” action, otherwise the new

67
802.1Q VLAN
Virtual Local Area Network (VLAN) can be implemented on the switch to logically create
different broadcast domain.
When the 802.1Q VLAN function is enabled, all ports on the switch belong to default
VLAN of VID 1, which means they logically are regarded as members of the same
broadcast domain. The valid VLAN ID is in the range of number between 1 and 4094.
The amount of VLAN groups is up to 256 including default VLAN that cannot be deleted.
Each member port of 802.1Q is on either an Access Link (to be VLAN-tagged) or a Trunk
Link (will not be VLAN-tagged). All frames into an Access Link carry no VLAN
identification. Conversely, all frames into a Trunk Link are previously VLAN-tagged.
Besides, there is the third mode—Hybrid. A Hybrid Link can carry both VLAN-tagged
frames and untagged frames. A single port is supposed to belong to one VLAN group,
except when it is on a Trunk/Hybrid Link.
The technique of 802.1Q tagging inserts a 4-byte tag, including VLAN ID of the
destination port—PVID, in the frame. With the combination of Access/Trunk/Hybrid Links,
the communication across switches also can make the packet sent through tagged and
untagged ports.
68
802.1Q Configuration
Pull down the selection item and focus on 802.1Q then press to set the
VLAN Operation Mode in 802.1Q mode.
Enable GVRP Protocol: GVRP (GARP VLAN Registration Protocol) is a protocol
that facilitates control of virtual local area networks (VLANs) within a larger network.
GVRP conforms to the IEEE 802.1Q specification, which defines a method of
tagging frames with VLAN configuration data. This allows network devices to
dynamically exchange VLAN configuration information with other devices. For
example, having enabled GVRP on two switches, they are able to automatically
exchange the information of their VLAN database. Therefore, the user doesn’t need
to manually configure whether the link is trunk or hybrid, the packets belonging to the
same VLAN can communicate across switches. Tick this checkbox to enable GVRP
protocol. This checkbox is available while the VLAN Operation Mode is in 802.1Q
mode.
Management VLAN ID: Only when the VLAN members, whose Untagged VID
(PVID) equals to the value in this column, will have the permission to access the
switch. The default value is ‘0’ that means this limit is not enabled (all members in
different VLANs can access this switch).
Select the port you want to configure.
Link Type: There are 3 types of link type.
Access Link: A segment which provides the link path for one or more stations
to the VLAN-aware device. An Access Port (untagged port), connected to the
access link, has an untagged VID (also called PVID). After an untagged frame
gets into the access port, the switch will insert a four-byte tag in the frame. The
contents of the last 12-bit of the tag is untagged VID. When this frame is sent
out through any of the access port of the same PVID, the switch will remove the
tag from the frame to recover it to what it was. Those ports of the same
untagged VID are regarded as the same VLAN group members.
69
Note: Because the access port doesn’t have an understanding of tagged frame, the
column field of Tagged VID is not available.
Trunk Link: A segment which provides the link path for one or more VLAN-
aware devices (switches). A Trunk Port, connected to the trunk link, has an
understanding of tagged frame, which is used for the communication among
VLANs across switches. Which frames of the specified VIDs will be forwarded
depends on the values filled in the Tagged VID column field. Please insert a
comma between two VIDs.
Note:
1. A trunk port doesn’t insert tag into an untagged frame, and therefore the untagged
VID column field is not available.
2. It’s not necessary to type ‘1’ in the tagged VID. The trunk port will forward the frames
of VLAN 1.
3. The trunk port has to be connected to a trunk/hybrid port of the other switch. Both the
tagged VID of the two ports have to be the same.
Hybrid Link: A segment which consists of Access and Trunk links. The hybrid
port has both the features of access and trunk ports. A hybrid port has a PVID
belonging to a particular VLAN, and it also forwards the specified tagged-frames
for the purpose of VLAN communication across switches.
Note:
1. It’s not necessary to type ‘1’ in the tagged VID. The hybrid port will forward the
frames of VLAN 1.
2. The trunk port has to be connected to a trunk/hybrid port of the other switch. Both
the tagged VID of the two ports have to be the same.
Untagged VID: This column field is available when Link Type is set as Access Link
and Hybrid Link. Assign a number in the range between 1 an 4094.
Tagged VID: This column field is available when Link Type is set as Trunk Link and
Hybrid Link. Assign a number in the range between 1 an 4094.

The Rapid Spanning Tree Protocol (RSTP) is an evolution of the Spanning Tree Protocol
and provides for faster spanning tree convergence after a topology change. The system
also supports STP and the system will auto-detect the connected device that is running
STP or RSTP protocol.

RSTP - System Configuration
The user can view spanning tree information of Root Bridge.
The user can modify RSTP state. After modification, click .
RSTP mode: The user must enable the RSTP function first before configuring
the related parameters.
Priority (0-61440): The switch with the lowest value has the highest priority and
is selected as the root. If the value is changed, the user must reboot the switch.
The value must be a multiple of 4096 according to the protocol standard rule.
Max Age (6-40): The number of seconds a switch waits without receiving
Spanning-tree Protocol configuration messages before attempting a
reconfiguration. Enter a value between 6 through 40.
Hello Time (1-10): The time that controls the switch to send out the BPDU
packet to check RSTP current status. Enter a value between 1 through 10.
Forward Delay Time (4-30): The number of seconds a port waits before
changing from its Rapid Spanning-Tree Protocol learning and listening states to
the forwarding state. Enter a value between 4 through 30.
[NOTE]
Follow the rule as below to configure the MAX Age, Hello Time, and Forward
Delay Time.
2 x (Forward Delay Time value –1) > = Max Age value >= 2 x (Hello Time
value +1)

RSTP—Port Configuration
You can configure path cost and priority of every port.
Select the port in the port column field.
Path Cost: The cost of the path to the other bridge from this transmitting bridge at
the specified port. Enter a number 1 through 200,000,000.
Priority: Decide which port should be blocked by priority in LAN. Enter a number 0
through 240 (the port of the highest value will be blocked). The value of priority must
be the multiple of 16.
Admin P2P: Some of the rapid state transactions that are possible within RSTP are
dependent upon whether the port concerned can only be connected to exactly one
other bridge (i.e. it is served by a point-to-point LAN segment), or can be connected
to two or more bridges (i.e. it is served by a shared medium LAN segment). This
function allows the P2P status of the link to be manipulated administratively. True is
P2P enabling. False is P2P disabling.
Admin Edge: The port directly connected to end stations won’t create bridging loop
in the network. To configure the port as an edge port, set the port to “True” status.
Admin Non Stp: The port includes the STP mathematic calculation. True is not
including STP mathematic calculation. False is including the STP mathematic
calculation.

SNMP Configuration
Simple Network Management Protocol (SNMP) is the protocol developed to manage
nodes (servers, workstations, routers, switches and hubs etc.) on an IP network. SNMP
enables network administrators to manage network performance, find and solve network
problems, and plan for network growth. Network management systems learn of problems
by receiving traps or change notices from network devices implementing SNMP.

QoS Configuration
You can configure QoS mode, 802.1p priority [7-0] setting, Static Port Ingress Priority
setting and TOS setting.
QoS Policy and Priority Type
Qos Mode: Select the QoS policy rule.
Disable QoS Priority: The default status of Qos Priority is disabled.
High Empty Then Low: When all the high priority packets are empty in queue,
low priority packets will be processed then.
Highest:SecHigh:SecLow:Lowest:8:4:2:1: The switch will follow 8:4:2:1 rate
to process priority queue from Highest to lowest queue. For example: the
system will process 80 % highest queue traffic, 40 % SecHigh queue traffic, 20
% SecLow queue traffic, and 10 % Lowest queue traffic at the same time. And
the traffic in the Lowest Priority queue are not transmitted until all Highest,
SecHigh, and SecLow traffic are serviced.
Highest:SecHigh:SecLow:Lowest:15:7:3:1: The process order is in
compliance with the transfer rate of 15:7:3:1.
Highest:SecHigh:SecLow:Lowest:15:10:5:1: The process order is in
compliance with the transfer rate of 15:10:5:1.
802.1p priority [7-0]: Configure per priority level. Each priority has 4 priority levels—
Highest, SecHigh, SecLow, and Lowest.
Default Ingress Port Priority Mapping:
The port ingress level is from 0 to 7.
TOS/DSCP Priority Mapping: The system provides 0 ~ 63 TOS priority level. Each
level has 8 priorities—0 ~ 7. The default value is "0" priority for each level. When the
IP packet is received, the system will check the TOS level value in the IP packet that
84
has received. For example, user set the TOS level 25 as 0. The port 1 is following
the TOS priority policy only. When the port 1 packet received, the system will check
the TOS value of the received IP packet. If the TOS value of received IP packet is 25
(priority = 0), and then the packet priority will have highest priority.

85
IGMP Configuration
The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet
Protocol (IP) suite. IP manages multicast traffic by using switches, routers, and hosts that
support IGMP. Enabling IGMP allows the ports to detect IGMP queries, report packets,
and manage IP multicast traffic through the switch. IGMP has three fundamental types of
message shown as follows:
Message
Description
Query
A message sent from the querier (IGMP router or switch)
asking for a response from each host belonging to the
multicast group.
Report
A message sent by a host to the querier to indicate that the
host wants to be or is a member of a given group indicated
in the report message.
Leave
Group
A message sent by a host to the querier to indicate that the
host has quit being a member of a specific multicast group.
The switch supports IP multicast. You can enable IGMP protocol via setting the IGMP
Configuration page to see the IGMP snooping information. IP multicast addresses are in
the range of 224.0.0.0 through 239.255.255.255.
IGMP Protocol: Enable or disable the IGMP protocol.
IGMP Query: Select the IGMP query function as Enable or Auto to set the switch as
a querier for IGMP version 2 multicast networks.
Click .

LLDP Configuration
LLDP (Link Layer Discovery Protocol) function allows the switch to advertise its
information to other nodes on the network and store the information it discovers.
LLDP Protocol: Disable or enable LLDP function.
LLDP Interval: Set the interval of learning the information time in second.
Click .

87
X-Ring
X-Ring provides a faster redundant recovery than Spanning Tree topology. The action is
similar to STP or RSTP, but the algorithms between them are not the same.
In the X-Ring topology, every switch should be enabled with X-Ring function and two
ports should be assigned as the member ports in the ring. Only one switch in the X-Ring
group would be set as the master switch that one of its two member ports would be
blocked, called backup port, and another port is called working port. Other switches in the
X-Ring group are called working switches and their two member ports are called working
ports. When the failure of network connection occurs, the backup port of the master
switch (Ring Master) will automatically become a working port to recover from the failure.
The switch supports the function and interface for setting the switch as the ring master or
not. The ring master can negotiate and place command to other switches in the X-Ring
group. If there are 2 or more switches in master mode, the software will select the switch
with lowest MAC address number as the ring master. The X-Ring master ring mode can
be enabled by setting the X-Ring configuration interface. Also, the user can identify
whether the switch is the ring master by checking the R.M. LED indicator on the panel of
the switch.
The system also supports the Couple Ring that can connect 2 or more X-Ring group for
the redundant backup function; Dual Homing function that can prevent connection lose
between X-Ring group and upper level/core switch.
Enable Ring: To enable the X-Ring function, tick the checkbox beside the Enable
Ring string label. If this checkbox is not ticked, all the ring functions are unavailable.
Enable Ring Master: Tick the checkbox to enable this switch to be the ring
master.
1
st
& 2nd Ring Ports: Pull down the selection menu to assign the ports as the
member ports. 1st Ring Port is the working port and 2nd Ring Port is the
88
backup port. When 1st Ring Port fails, the system will automatically upgrade the
2
nd
Ring Port to be the working port.
Enable Couple Ring: To enable the coupe ring function, tick the checkbox beside
the Enable Couple Ring string label.
Couple Port: Assign the member port which is connected to the other ring
group.
Control Port: When the Enable Couple Ring checkbox is ticked, you have to
assign the control port to form a couple-ring group between the two X-rings.
Enable Dual Homing: Set up one of the ports on the switch to be the Dual Homing
port. For a switch, there is only one Dual Homing port. Dual Homing function only
works when the X-Ring function enabled.
Homing Port: Assign a port which is used to be the dual homing port.
And then, click to have the configuration taken effect.
X-ring Interface
[NOTE]
1. When the X-Ring function enabled, the user must disable the RSTP. The X-Ring
function and RSTP function cannot exist on a switch at the same time.
2. Remember to execute the “Save Configuration” action, otherwise the new
89
configuration will lose when switch powers off.
Security
In this section, you can configure the 802.1x and MAC address table.
802.1X/Radius Configuration
802.1x is an IEEE authentication specification which prevents the client from connecting
to a wireless access point or wired switch until it provides authority, like the user name
and password that are verified by an authentication server (such as RADIUS server).
System Configuration
After enabling the IEEE 802.1X function, you can configure the parameters of this
function.
IEEE 802.1x Protocol: Enable or disable 802.1x protocol.

MAC Address Table
Use the MAC address table to ensure the port security.
93
Static MAC Address
You can add a static MAC address; it remains in the switch's address table, regardless of
whether the device is physically connected to the switch. This saves the switch from
having to re-learn a device's MAC address when the disconnected or powered-off device
is active on the network again. You can add / modify / delete a static MAC address.
Add the Static MAC Address
You can add static MAC address in the switch MAC table in here.
MAC Address: Enter the MAC address of the port that should permanently forward
traffic, regardless of the device network activity.
Port No.: Pull down the selection menu to select the port number.
