2.2 Industrial Ethernet Technology
The line of switches from WAGO ensure the scalability of your network
infrastructure with outstanding electrical and mechanical characteristics. These
robust devices are designed for industrial use and they are fully compliant with
IEEE802.3, 802.3u.
They have function monitoring and redundant voltage supply with a supply
voltage range of 9 … 48 V. Alarm functions are enabled via DIP switch.
Characteristics such as auto negotiation and auto MDI/MDIX (crossover) on all
10/100 BaseTX ports are also realized, as is a store-and-forward switching mode.
Pos: 9.4 /Serie 852 (Ethernet-Zubehör)/Einleitu ng/ Switch Technologie @ 3\mod_1222683606296_21.doc @ 22317 @ 2 @ 1
2.3 Switching Technology
Another approach to pushing beyond the limits of Ethernet technology is the
development of switching technology. A switch bridge Ethernet packets at the
MAC address level of the Ethernet protocol transmitting among connected
Ethernet or Fast Ethernet LAN segments.
Switching is a cost-effective way of increasing the total network capacity
available to users on a local area network. A switch increases capacity and
decreases network loading by dividing a local area network into different
segments, which don’t compete with each other for network transmission
capacity.

The Industrial Switch was designed for easy installation in an industrial
environment where vibration, shock, heat, and RF interference may be
commonplace.
The Industrial Switch, with its small, compact size, was specifically designed for
easy DIN rail mounting and can be installed where space is limited.
The Industrial Switch is ideal for deployment with multiple high-speed servers for
shared bandwidth 10 Mbps or 100 Mbps workgroups. With the highest bandwidth
200 Mbps (100 Mbps full duplex mode), any port can provide workstations with a
congestion-free data pipe for simultaneous access to the server.
The Industrial Switch is expandable by cascading two or more switches together
in a ‘daisy-chain’ fashion. As all ports support 200 Mbps, the Industrial Switch
can be cascaded from any port and to any number of switches.
The Industrial Switch combines dynamic memory allocation with store-and
forward switching to ensure that the buffer is effectively allocated for each port,
while controlling the data flow between the transmit and receive nodes to
guarantee against all possible packet loss.

3 Hardware Description
The Industrial Managed Switch was developed with both “Xpress Ring” and “Jet
Ring” features. The Jet ring offers recovery time of less than 300 ms in case of
any network-link failure – and the Xpress Ring can recover from such a failure
within 50 ms. This makes the Industrial Managed Switch particularly suited for
industrial applications that demand the utmost reliability. The device comes with
7 copper and 2 fiber ports that provide 10/100 Base fiber-to-copper conversion.
With its industrial design, the Industrial Managed Switch ensures "always-on"
connectivity, eliminating costly network downtime.
Being SNMP-ready, the Industrial Managed Switch enables network managers to
remotely monitor the entire network’s status quickly and easily via an RJ-45 or a
console port connection. This Industrial Managed Switch can extend an
enterprise’s industrial Ethernet configuration range up to 30 km, while
simultaneously minimizing troubleshooting time. The Industrial Managed Switch
is designed with 'plug-n-play' features for hassle-free integration into today's
managed mixed-cabling network configurations.
Pos: 11.2 /Dokumentation allgemein/Gliederungse lemente/---Seitenwechsel--- @ 3\mod_1221108045078_0.doc @ 21810 @ @ 1
Featuring Auto MDI/MDI-X detection for direct connection to a workstation,
switch or hub, network managers no longer need to worry about the cable
configuration (cross-over or straight through) when establishing connections
between RJ-45 ports.
The Industrial Managed Switch has auto-negotiation capabilities that allow it to
support connection with leading NWay switches. In full-duplex mode, this unit
can sustain distances of up to 2 km (for multi-mode fiber) and 30 km (for longhaul single-mode fiber) between it and a LAN switch or another switch or
data/file server.
The Industrial Managed Switch features both RJ-45 jacks and slots for LC (SFPtype) fiber-optic connectors that allow it to connect a 10/100Base-TX network to
a 100Base-FX (fiber-based) network.

3.1 Connectors
This Industrial Managed Switch utilizes ports with fiber or copper port connectors
functioning under Ethernet and/or Fast Ethernet protocols.
3.1.1 10/100BASE-TX Ports
The 10/100BASE-TX ports support network speeds of either 10 Mbps or
100 Mbps, and can operate in half- and full-duplex transfer modes. The ports also
offer automatic MDI/MDI-X crossover detection that gives true “plug and play”

6.1 DC Power Connection
The Industrial Switch uses a DC power supply of 9 … 48 V DC.
The primary and redundant power connection is provided via a terminal block
located at the top of the Industrial Switch.
The terminal block is composed of six contact pins and can be inserted and
removed easily by hand to connect to the six pin terminal block receptor (male
contacts located on the body of the Switch).
The Switch’s power supply automatically self adjusts to the local power source
and may be powered on without having any or all LAN segment cables connected.
1 Check the front panel LEDs as the device is powered on to verify that the
Power LED is lit. If not, check that the power cable is correctly and securely
plugged in.
2 If a redundant power supply is connected, an RPS LED will be illuminated.
3 „PWR +/-„ conductors:
To connect or disconnect the conductors, actuate the spring directly in the
female connector using a screwdriver or an operating tool and insert or
remove the conductor.
4 For the back up DC connection, follow the same procedure as above. Attach
power wires to the terminal block (in the position marked RPS +/-).
5 If the terminal block is not already inserted into the block receptor of the
Switch, do so now.

6.2 External Alarm Contact Connection
The Industrial Switch has one alarm contact connection point located on the grey
terminal block on the top panel. For detailed instructions on how to connect the
alarm contact power wires to the two ALM contacts of the 6 contact terminal
block connector, see the procedure for connecting DC Power in the section above
(it is the same procedure).
You can connect the alarm circuit to any warning device which the user´s factory
or industry already has installed in the control room or factory floor. When a fault
occurs, the Industrial Switch will send a signal through the alarm contact, to
activate this external alarm. The alarm contact has two terminals that form a fault
circuit for connecting to alarm system.
An alarm will be signaled in the following situations:
1 Port link failure (e.g.: cable disconnected, device breakdown, etc.)

6.3 Fiber Cable Connection
When connecting fiber cable to a 100BASE-FX port on the Industrial Managed
Switch, be sure the correct type (LC) of connector and SFP module is used.
Various types of multi mode, single mode, or WDM SFP modules are sold
separately. Follow the steps below to properly connect the fiber cabling:
Please note
Remove and keep the fiber port’s (LC) rubber covers. When not connected to a
fiber cable, the rubber cover should be in place to protect the fiber optics.
Pos: 19 /Dokumentation allgemein/Gliederungsele mente/---Seitenwechsel--- @ 3\mod_1221108045078_0.doc @ 21810 @ @ 1
1 Plug in the appropriate SFP modules.
2 Check that the fiber terminators are clean. You can clean the cable plugs by
wiping gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber cables will impair the quality of the
light transmitted through the cable and lead to degraded performance on the
port.
3 Connect one end of the cable to the LC port on the Industrial Managed
Switch and the other end to the fiber port of the other device.
Please note
When inserting the cable, be sure the tab on the plug clicks into position to ensure
that it is properly connected.

7.1 Jet Ring – for Communication Reliability
Setting up Jet Ring (redundant linking) on your network helps to protect critical
links against failure and network loops; and it reduces network downtime to less
than 300 ms.
The Jet Ring function allows users to set up a redundant path in the network to
provide a backup data-transmission route in the event that a connection is abruptly
disconnected or damaged. This is an extremely important feature in industrial
applications because a link failure in a link with no backup can cause several
minutes of network downtime and thus cause heavy losses.
7.2 How Jet Ring Recovers in less than 300 ms
The Jet Ring protocol is designed to optimize redundant communication linking
and deliver a very fast link-recovery period. The Jet Ring automatically identifies
one switch as the “master” of the network, and then automatically blocks ports to
prevent packets from traveling through any of the network’s redundant loop
segments. If one segment of this ring becomes disconnected from the rest of the
network because of a link failure, the Jet Ring protocol automatically re-adjusts
the ring so that the part of the network that was disconnected, re-establishes
contact with the rest of the network.
The user does not need to designate the master switch to use Jet Ring, this is done
automatically.
The Jet Ring ensures smooth operation of industrial automation devices in many
critical applications. It will put your automation system back to full operability in
less than 300 ms if any node of your network goes down.

7.3 Xpress Ring
Xpress Ring is a ring protocol that enables networks to recover from link failure
within 50 ms. Unlike Jet Ring, it needs some network configuration efforts: The
user must assign two ring ports for each Switch in the ring. The user must also
assign the Arbiter Switch, which will decide if it is necessary to activate the
backup path. For Xpress Ring, any switch can be the arbiter – just remember that
the arbiter switch must be part of the ring.
Apart from rerouting the transmission within 50 ms, the Arbiter Switch will also
issue an alarm when a link failure occurs. The user will then be informed of the
failure and will be able to fix the problem and reconfigure if required.
Xpress Ring is the faster ring recovery technology and is ideal for networks where
the ring topology is not changed very often.
Please refer to the following chapter for the configuration of the Xpress Ring.

7.4 Coupling Ring
The Coupling Ring function connects two Xpress Rings via redundant links
(Primary Link & Secondary Link). Please refer to the following illustration. When
the primary link (port 2 at the Master Switch of coupling role) fails, the secondary
link (port 2 at the Arbiter Switch of coupling role) will automatically kick in
within milliseconds. The Secondary Link is blocked during normal operations,
and it is enabled automatically when the Primary Link is disconnected. The
Secondary Link is blocked again automatically when the Primary Link recovers.
Control Line of Coupling Ring (port 1 at the Master Switch of coupling role/port
1 at the Arbiter Switch of coupling role) is used for negotiation between Master
and Arbiter Switches of coupling role and to decide when the secondary link
should be enabled or blocked. It is needed to set coupling roles as “Master”,
“Arbiter”, or “Normal” (all other Switches not Master neither Arbiter) to Switches
in the Xpress Ring, and assign coupling’s ring and control ports to the Master and
Arbiter Switches, to one side only of two interconnected rings.
Coupling Ring is designed based on Xpress Ring. For configuring the Coupling
Ring feature, please consult the appropriate chapter in this manual.

8.1 Overview of Configuration Options
For advanced management capabilities, the onboard management agent provides
CLI and menu driven interface configuration programs. These programs can be
accessed by a direct or modem connection to the console port on the front panel
(local), or by a Telnet connection over the network.
The management agent is based on SNMP (Simple Network Management
Protocol). This SNMP agent permits the switch to be managed from any PC in the
network by using management software.
The management agent also includes an embedded HTTP Web agent. This Web
agent can be accessed using a standard Web browser from any computer attached
to the network.
The Industrial Managed Switch gives you the flexibility to access and manage it
by using any or all of the methods described. The administration console and web
browser interfaces are embedded in the switch software and can be used
immediately after setup.

Advantages:
• Communicates with switch functions at the MIB level
• Based on open standards
The three methods for configuring the Industrial Managed Switch management
agent are explained in this chapter.
The first method – Command Line Interface (CLI) via the Console Port to initially
set IP parameters – is explained in part A.
The second is Menu Driven configurations via Telnet – explained in part B.
Part C explains the use of an Internet Browser Interface to configure the Industrial
Managed Switch.
Part D provides some basic operational examples for using CLI via Telnet.
Complete part A and then proceed to either part B, C or D.

8.2 A - Console Port
Local Connection
Prior to accessing the Industrial Managed Switch’s onboard agent via a network
connection, you must first configure it with a valid IP address, subnet mask, and
default gateway using a local connection or the BOOTP protocol.
After configuring the Industrial Managed Switch’s IP parameters, you can access
the onboard configuration program from anywhere within the attached network or
via Internet. The onboard configuration program can be accessed using Telnet
from any computer attached to the network. It can also be managed from any
computer using a Web browser (Internet Explorer 4.0 or above, or Netscape
Navigator 4.0 or above).
Access the Industrial Managed Switch via a terminal emulator (such as Hyper
Terminal) attached to the console port. The console port is set at the factory with
the following default COM port properties. Configure your own terminal to match
the following:

8.3.3 (DCM)/Bridge Menu
The Bridge Menu is used to Enable/Disable STP (Spanning Tree Protocol
Algorithm), JET Ring or Xpress Ring, as well as to configure the STP settings if
STP is enabled.
If Jet Ring is enabled it offers a fast recovery time of less than 300 ms in case a
node goes down in the ring. Xpress Ring offers a very fast recovery time of less
than 50 ms.
The Spanning Tree Algorithm is used for detecting and disabling network loops,
and to provide backup links between switches, bridges and routers. This allows
the switch to communicate and interact with other bridging devices (i.e. STPcompliant devices) in a network to ensure that only one route exists between any
two stations, and provide redundant or backup links that automatically take over
when a primary link fails.

8.3.5 (DCM)/VLAN (Virtual Local Area Networks) Menu
Figure 30: VLAN Menu
A VLAN is a network of computers behaving as though they are connected to the
same LAN segment, even though their physical location may be on a different
LAN altogether. VLANs are configured through software rather than hardware,
which make them extremely flexible.
Some of the advantages of VLANs are:
• When a computer is physically moved to another location, it can stay on the
same VLAN without any hardware reconfiguration because VLANs are not
limited by hardware constraints.
• VLANs can be configured to define a network into various logical
configurations. For example, VLANs can define a network by application.
In this scenario, a company might create one VLAN for multimedia users
and another for e-mail users.
• VLANs can also define a network by department. For example, a company
might have one VLAN for its Engineering Department, another for its
Marketing Department, and another for its Sales Dept.
• VLANs can also be set up according to the organization’s internal structure.
For example, the company president might have his/her own VLAN, the
executive staff might have a different VLAN, and the remaining employees
might have yet another VLAN.
As these examples show, VLANs offer unparalleled flexibility. The following
section describes how VLANs can be deployed using the Switch.

8.3.5.2 Tag-based VLANs
The concepts of tag-based VLAN
Tag-based VLAN is the standard implementation of IEEE802.1Q VLAN. With
the Industrial Managed Switch set as a tag-based VLAN switch, every port has the
following:
PVID
Port VLAN ID number, generally referring to the VLAN, which the connected
non-802.1Q-aware device (like a Device Server or Industrial Computer) belongs
to. This PVID can be configured in the menu Port Information.
Priority
Priority of the port and the non-802.1Q packets received on the port – generally
from a non-802.1Q-aware device. (Port Info menu)
Participating VLANs
The VID-tagged packets, which are allowed to flow in or out of the port. A port
may participate in multiple VLANs, like an uplink port connected to another
switch, which will transfer the packets from various devices belonging to different
VLANs into the network. (BUT, generally, a port connected to a peripheral non-
802.1Q device can only participate in 1 VLAN, the same VLAN ID that is
selected for that port in the “Port Info” menu). The participating VLANs can be
configured in the menu Add VLAN Group.
If the port is set in the Add VLAN Group menu as a Tagged Port, all packets
flowing out of the port will be tagged frames to an 802.1Q switch or device.
If the port is set as an Untagged Port, all packets out of the port will be untagged
frames (stripped of their tags at port) to a non-802.1Q device, like an industrial
computer.
When a packet is received (ingress) on the port, it is filtered to be dropped or
forwarded according to the user-specified rule (configured on menu “Port
Information”) for ingress-filtering untagged frames and tagged frames that are not
members of the receiving port’s participating VLANs (configured on menu Add
VLAN Group).
If the packet is forwarded, the untagged frames, generally from a non-802.1Qaware peripheral or device, are tagged with the PVID and Priority that were
assigned to the Ingress port.

The untagged packets received by an 802.1Q Switch in this way become tagged
frames. The tagged frames received on the ingress port are kept unchanged if it’s
not dropped.
Next, the Industrial Managed Switch switches the frame into the egress port that is
a participant of that specific VLAN.
For example: If the ingress is from a peripheral device linked to a downlink port
on a switch with only one uplink port and the frame is addressed to a device on
another switch, the frame would be switched to egress out of the uplink port – and
this UPlink port would be set to participate in the VLANs of all the DOWNlink
ports and forward all their traffic.
If the egress port is an “untag” port (normally a port linked to a peripheral, non-
802.1Q device that does not accept tagged frames), the VID and priority fields
will be stripped off (untagged) from the frame and then transmitted out of the
egress port.
A previously tagged frame is simply kept unchanged when it is sent out from a
“tagging” egress port, generally to a 802.1Q switch or a standard VLAN-aware
device.

After logging into the system, you can use this menu to configure the settings for
remote access via SNMP agent and to configure the e-mail alarm or to upgrade
the firmware. The user should set the community string that controls access to the
onboard SNMP agent via in-band management software (SNMP Configuration).
The items provided by the Management Setup Menu are described in the
following sections.

(MSM)/SNMP Configuration Menu
Use the SNMP Configuration screen to display and modify parameters for the
Simple Network Management Protocol (SNMP). The Switch features an onboard
SNMP agent that monitors the status of its hardware as well as the traffic passing
through its ports. A computer attached to the network, called a Network
Management Station (NMS), can be used to access this information. Community
strings control access rights to the agent module. To communicate with the
switch, the NMS must first submit a valid community string for authentication.
The options for configuring community strings and related trap functions are
described in the following figures and tables.

You can use an external SNMP-based application to configure and manage the
Switch. This management method requires the SNMP agent on the Switch and the
SNMP Network Management Station to use the same community string. This
management method, in fact, uses two community strings: the GET community
string and the SET community string. If the SNMP Network Management Station
only knows the SET community string, it can read and write to the MIBs.
However, if it only knows the GET community string, it can only read MIBs. The
default GET and SET community string for the Switch is “public”.

8.4.4 Bridge Menu
Using the Bridge Menu
The Bridge menu is used for configuring the Jet Ring, Spanning Tree Algorithm
and Xpress Ring settings, as well as the traffic class priority threshold and the
address aging time.
The Jet Ring offers fast recovery time of less than 300 ms in case of link failure
(if Jet Ring is enabled). It has a longer recovery time than Xpress Ring (50 ms),
but it needs almost no set-up configuration.
Xpress Ring offers a very fast link-failure recovery time of 50 ms, but the user
must select the role of the Switch (arbiter or forward) and which two ports will be
part of the Xpress Ring network.
The Spanning Tree Algorithm is used for detecting and disabling network loops,
and to provide backup links between switches, bridges or routers. This allows the
switch to communicate and interact with other bridging devices (i.e. STAcompliant devices) in a network to ensure that only one route exists between any
two stations, and it provides redundant or backup links that automatically take
over when a primary link goes down.

STP allows the Switch to assign a priority status to each of its ports, with respect
to other networking nodes in the network. In other words, STP determines the best

8.4.6 Virtual Local Area Networks (VLAN)
A VLAN is a network of computers behaving as though they are connected to the
same segment, even though their physical location may be on a different segment
of a LAN altogether. VLANs are configured through software rather than
hardware, which makes them extremely flexible.
Some of the advantages of VLANs are:
• When a computer is physically moved to another location, it can stay on the
same VLAN without any hardware reconfiguration because VLANs are not
limited by hardware constraints.
• VLANs can be configured to define a network into various logical
configurations. For example, VLANs can define a network by application.
In this scenario, a company might create one VLAN for multimedia users
and another for e mail users.
• VLANs can also define a network by department. For example, a company
might have one VLAN for its Engineering Department, another for its
Marketing Department, and another for its Sales Department.
• VLANs can also be set up according to the organization’s internal structure.
For example, the company president might have his/her own VLAN, the
executive staff might have a different VLAN, and the remaining employees
might have yet a different VLAN.
As these examples show, VLANs offer incomparable flexibility. The following
section describes how VLANs can be deployed using the Switch.

Table 37: Tag-Based Info Menu
Parameter Description
No
The port is not participating in the VLAN as identified by
the selected VID (VLAN ID).
Untagging
The port is an untagging port (as defined in 802.1Q) that is
participating in the VLAN. In such an untagged port the
Switch will strip off the 802.1Q tag from the incoming and
outgoing frames if they are tagged in such a way. This is
used for sending frames to non-802.1Q-compliant devices.
Tagging
The port is a tagging port (as defined in 802.1Q) and is
participating in the VLAN. The Switch will put the VLAN
information of the port – including VID and Priority – into
the header of the untagged frames coming in or transmitted
from the port. The tagged VLAN information in the frames
can later be used by other 802.1Q-compliant devices for
forwarding decisions.

8.4.7 IGMP Menu – Using the IGMP Menu
The IGMP menu is used for configuring IGMP snooping. IGMP means "Internet
Group Management Protocol". It is a protocol through which hosts can register
with their local router for multicast services. If there is more than one multicast
router on a given sub-network, one of the routers is elected and assumes the
responsibility of keeping track of group membership.
SS20 – IGMP Configuration
This menu allows the user to Enable/Disable IGMP Snooping and IGMP Query.
Please note
In order to keep the switch traffic efficient, the last byte of the IP address should
not be the same as in the IGMP group. E.g. if the Switch’s IP address is
192.168.0.10 and the IGMP router/switch’s IP address is 192.168.21.10, this will
make the switch less efficient.

change the NIC of the PC or IP appliance, the new MAC address will be learned
in 3 minutes by the Switch, with the set quantity limitations. The MAC Limit
Function can be disabled or enabled per port, under the parameter labeled Action
in the table. Generally this function is only enabled for downlink ports.

You can use an external SNMP-based application to configure and manage the
switch. This management method requires the SNMP agent on the switch and the
SNMP Network Management Station to use the same community string. This
management method, in fact, uses two community strings: the GET community
string and the SET community string. If the SNMP Network Management Station
only knows the SET community string, it can read and write to the MIBs
(Management Information Bases of the devices), but, if it only knows the GET
community string, it can only read the MIBs.
The default GET and SET community strings for the switch is public.
