This managed industrial switch comes equipped with a proprietary
redundant network protocol—X-Ring which provides an easy way to
establish a redundant Ethernet network. With ultra high-speed recovery
time (less than 300 ms) and a long MTBF (Mean Time Between Failures)
the industrial switch will continue to operate until a Gigabit network
infrastructure has been established, without requiring extra upgrade
costs.
In addition to10/100/1000Base-TX fast Ethernet ports, the switch has
SFP (mini-GBIC) ports. Traditiona l RJ-4 5 por ts can be us ed fo r up l inking
short distance (less than 100 m) wide-band paths, while the SFP slots
can be used for the application of wideband uploading and long distance
transmissions adding flexibility.

RJ-45 ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for
10Base-T, 100Base-TX or 1000Base-T devices connections and Auto
MDI/MDIX.
RJ-45 Pin Assignments
Pin Number Assignment
All ports on this industrial switch support automatic MDI/MDI-X operation.
You can use straight-through cables (See Figure below) for all network
connections to PCs or servers, or to other switches or hubs. In
straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are
connected straight through to pins 1, 2, 3 and 6 at the other end of the
cable. The 10BASE-T/100BASE-TX/1000BASE-T MDI and MDI-X port
pin outs are as tabled below.

Use the four twisted-pair, Category 5e or above cabling for RJ-45 port
connection. The cable between the switch and the link partner (switch,
hub, workstation, etc.) must be less than 100 meters (328 ft.) long.
The small form-factor pluggable (SFP) is a compact optical transceiver
used in optical communications for both telecommunication and data
communication applications.
Follow these steps to connect the transceiver and LC Cable:
First, insert the transceiver into the SFP module. A triangle is marked on
the bottom of the module.

2. Ensure the DIN-Rail is tightly screwed to the Industrial switch. If not,
refer to DIN-Rail Mounting section for DIN-Rail installation. To panel
mount the Industrial switch, refer to Panel Mounting section.
3. Apply power to the switch (refer to the Wiring the Power Inputs
section). The power LED will light.
4. Connect CAT 5 cables to the Industrial switch’s RJ-45 ports and to the
network devices.
[NOTE] If the network devices do not support MID/MDIX, a
crossover cable may be required.

5. Connect the fiber optic cables to the industrial switch and network device.
Ensure that the switch’s fiber optic transmitter is connected to the
network devices receiver and vice versa.
6. Connect the fiber optic cables.
7. When all the connections are made and the LEDs show normal
indications, the installation is complete.
X-Ring Application
This switch incorporates the X-Ring Protocol to ensure network reliability
and system restoration within 300 ms in the event of a connection failure.
The X-Ring algorithm is similar to the spanning tree protocol (STP)
algorithm but it has faster recovery time. The following figure below is an
example of an X-Ring application.

If the network has more than one X-Ring group, the coupling ring function is
used to connect them and add redundancy. This ensur es that transmiss ions
between the two ring groups will not fail. The figure below is an example of
the coupling ring application.
Dual Homing Application
The Dual Homing function is used to prevent a connection loss between the
X-Ring group and the upper level/core switch. Assign a port in each X-ring
group to be the Dual Homing ports The Dual Homing function can only be
used when the X-Ring function is active. Each X-Ring group can have one
Dual Homing port. Note: The upper level switches must have RSTP
enabled.

When the connection between Switch and PC is ready, turn on the PC, run
a terminal emulation program or Hyper Terminal, and configure the

The Link Aggregation Control Protocol (LACP) provides a standardized
method for exchanging information between Partner Systems on a link. This
allows their Link Aggregation Control instances to reach an agreement on
the identity of the Link Aggregation Group, move the link to that Link
Aggregation Group, and enable its transmission and reception functions in
an orderly manner. Link aggregation lets you group up to four consecutive
ports into two dedicated connections. This feature expands bandwidth to a
device on the network. LACP operation requires full-duplex mode.

A Virtual LAN (VLAN) can be thought of as a broadcast domain that exists
within a switch or a defined set of switches. By grouping switch ports into
VLANs, traffic flooding is limited since devices can only communicate
directly with devices belonging to the VLAN. Creating a VLAN from a switch
is the logical equivalent of reconnecting a group of devices to another Layer
2 switch. However, the network devices retain their same physical
connection. The switch supports port-based and 802.1Q (tagged-based)
VLAN. In the default configuration, the VLAN option is disabled.
VLAN Configuration interface
VLAN configuration - Port-based VLAN
With port-based VLAN, the port is assigned to a VLAN. Therefore, all
devices attached to a given port should be members of the same VLAN. As
with other VLAN configurations, the packets forwarded using this method do
not leak into other VLAN domains on the network. After the port has been
assigned to a VLAN, devices on the port cannot send to or receive from

Tagged-based VLAN is an IEEE 802.1Q specification, which allows VLANs
to be created across devices from different venders. IEEE 802.1Q VLAN
uses a technique to insert a “tag” into the Ethernet frame. The tag contains a
VLAN Identifier (VID).
When the 802.1Q VLAN is enabled, all ports on the switch belong to a
default VLAN (VID 1). The default VLAN cannot be deleted. Up to 64 VLAN
groups are supported.

TOS priority: the system provides 0 to 63 TOS priority levels. Each
level has four types of priority – high, midd le, low, and lowest. The default
value is ‘Lowest’. When an IP packet is received, the system will check the

and the port is following the TOS priority policy only, when a packet is
received, the system will check the TOS value of the received IP packet. If
the TOS value of received IP packet is 25(priority = high), then the packet

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 and report packets and manage IP multicast
traffic through the switch. IGMP has three fundamental types of message.

IGMP Configuration interface
X-Ring provides network redundancy similar to the Spanning Tree and
Rapid Spanning Tree Protocols. However, recovery time is greatly reduced
when the X-Ring protocol is used. The protocol identifies one switch as the
Ring Master. Packets are blocked from the redundant path unless a ring
member becomes disconnected from the rest of the network. When this
happens, the protocol automatically restores connectivity using the
redundant path.
In the X-Ring topology, every switch should enable X-Ring function and
assign two member ports to the r ing. Only one switch in the X-Ring gr oup
would be set as the backup switch. Other switches are called working
switches and their two member ports are called working ports. If a network

connection failure occurs, the backup port will automatically become a
working port to recover.
The switch can be set in the ring master or slave mode. The ring master
negotiates and places commands to the other switches in the X-Ring group.
If there are two or more switches in the master mode, the software will
select the switch with lowest MAC address number as the ring master. The
X-Ring master mode is enabled using the X-Ring configuration interface.
The Ring Master can also be identified using the R.M. LED on the front of
the switch.
The switch also supports coupling ring to connect two or more X-Ring
groups for redundant backup. The dual homing function is used to prevent a
connection lose between the X-Ring group and the upper level/core switch.
