Overview
This manual will help you install and maintain the Safety Ring Switch. The
Ring Switch allows you to implement the traditional star topology, or ring
topology to take advantage of network path redundancy. The switch canbe used right out of the box without configuration; or through some
simple configuration steps, some powerful managed switch features canbe enabled such as traffic prioritization and port mirroring.

Operation
In the Safety Ring Switch, messages are intelligently routed for the sakeof increasing the efficiency and reliability of your network. Unlike an
Ethernet hub, a switch will forward packets
to specific ports to reduce unnecessarytraffic on network paths, thus optimizing
network efficiency. Most importantly, byusing a Ring Switch, you can implement
redundant paths in a network by allowing
ring topology (for a more resilient network).
Ring topology is important in path
redundancy because no matter where in thering that a path gets “cut”, all devices
connected to a node in the ring will still beable to communicate with each other.
Conventional switches and hubs cannot be
used in ring topologies because of broadcast
storms. Broadcast storms can bring a
network to a stop if conventional switches or
hubs are being used in a ring topology
because of broadcast message reproduction. Using Ring Switches in theloop will prevent broadcast storms because they have the intelligence toPage 6 of 31

Safety Ring Switchdetect loops and to assign the necessary ports to be in the backup(disabled) state. These backup ports will be instantly enabled should theprimary path in their respective ring fail. See picture to the right:
The Ring Switch supports 10BaseT (10 Mbps), and 100BaseT (100 Mbps)
on its RJ45 ports. Each of these ports will independently auto-sense thespeed, allowing you to interface to regular or fast Ethernet devices. They
also have 100BaseF (100 Mbps) fiber optic port(s).

Safety Ring Switch

LED Indicators
Overview
The Safety Ring Switch has 2 communication LEDs for each port, and in
addition, two LEDS (OK and Ring) provide switch and network status.
Refer to the pictures below for the location of these LEDs.

OK LEDThe OK LED is a bi-colour LED. The LED will be ON green as long as power
is applied and all configured rings have continuous ring integrity.
Here are the possible states for the OK LED:➢OFF – This would indicate that the unit is not powered.

➢

ON ORANGE – One of the active rings for which this switch is amember of has encountered a segment failure.

➢

ON GREEN – Power on the unit is ok, and no problem is
encountered on active rings.

➢

Blinking orange / green – There are three blink rates:➢

Continuous rapid blinking orange: The user has selected the
Operations  Wink command, to visually identify the unit.

➢

Rapid blinking orange, with a single short pause: Should the
OK LED blink rapidly for about 5 seconds and then pause forabout 1 second, this indicates that the switch is in the boot-up
process.

➢

Long GREEN, short ORANGE: If the OK LED is GREEN for
about 1.9 seconds and ORANGE for .1 seconds, an internal
error has occurred in the Safety Ring switch.

Ring LED
The Ring LED turns ON when all rings enabled in the switch havecontinuous ring integrity. This LED also has the following indications.
●

OFF: The Safety Ring switch has not been configured for any rings.

●

Blinking: One or more rings have been configured for the Safety
Ring switch, but a break has been discovered for one or more of theconfigured rings. Neighboring Safety Ring switches are responding,so the break is at another location.
Safety Ring Switch

Page 9 of 31●

Blip: (Long OFF – Short ON) One or more configured rings havebeen broken. The break has been detected to be local to one of theports.

In simple rings, the segment with the problem will most likely be between
the two Safety Ring switches with their RING LEDs in the blip state.

Port LEDs
There are two LEDs per port. One LED indicating the speed (10/100/1000)
and one to indicate link and activity. The port states and LED blinking aredescribed below:●

Link/activity OFF - This would indicate that there is not a proper
Ethernet connection (Link) between the port and another Ethernet
device. Make sure the proper cable type is in use and that it has
been plugged securely into the ports at both ends.

●

Link/activity ON Solid (not flashing) – This would indicate that
there is a proper Ethernet connection (Link) between the port andanother Ethernet device, but no communications activity is detected.

●

Link/activity Blinking – This would indicate that there is a proper
Ethernet connection (Link) between the port and another Ethernet
device, and that there is communications activity detected on theport. Note that a port LED will blink when there is any kind ofcommunication activity detected on the port, even if thecommunication involves an Ethernet device other than the Safety
Ring switch, and even if the port of the Safety Ring switch has been
disabled.

●

Speed OFF – 10Mbs (10BaseTX) connection is detected.

●

Speed ORANGE – 100Mbs (100BaseTX) connection is detected.

Safety Ring Switch

Ethernet Wiring
Overview
The Safety Ring Switch provides Ethernet and fiber connections to deviceson the factory floor through star or ring topology. When wiring the Ring
Switch in a ring topology, it is important that only Safety Ring Switches
are used for each node in the ring. With proper ring wiring, all nodes in
the ring can maintain the same data connectivity should a path in the ringbe “cut”.

RJ45 Wiring guidelines
Use data-quality (not voice-quality) twisted pair cable rated category 5 or
better with standard RJ45 connectors with or without Neutrik Ethercon
connectors. For best performance use shielded cable. Straight through orcrossover category 5 cable can be used regardless of the type of device
connected to the Ring Switch. This is because the Ring Switch supports
auto-mdi/mdix-crossover.

Page 11 of 31

Notes for wiring diagrams above:➢

For patch cables, 568-B wiring is by far, the most common method.

➢

There is no difference in connectivity between 568B and 568A
cables. Either wiring should work fine on any system.

➢

For a straight through cable, wire both ends identical.

➢

For a crossover cable, wire one end 568A and the other end 568B.

➢

Do not confuse pair numbers with pin numbers. A pair number isused for reference only (eg: 10BaseT Ethernet uses pairs 2 & 3).
The pin numbers indicate actual physical locations on the plug andjack.

The maximum cable length for 10/100BaseT is typically 100 meters (328ft.).

Ethernet Fiber wiring guidelines
The Safety Ring Switch has two pair of multimode fiber ports. The
maximum segment length is up to 2 km.
Each fiber optic port on the switch is comprised of a pair of SC styleconnectors. For each fiber port there is a transmit (TX) and receive (RX)signal. When making your fiber optic connections, make sure that thetransmit (TX) port of the switch connects to the receive (RX) port of theother device, and the receive (RX) port of the switch connects to thetransmit (TX) port of the other device. See images below.
The ACT/LNK LED will be ON when you have made a proper connection.

Duplex operation
The RJ45 ports will auto-sense for Full or Half duplex operation, while thefiber ports are configured for full duplex operation. Note: Fiber devices
with half duplex settings should still communicate with the switch. Ifotherwise then contact your switch vendor.

Network device check
The Safety Ring Switch is capable of supporting 10/100BaseT and 100 or
1000BaseF. Make sure you connect the appropriate devices to each port.

Safety Ring Switch

Safety Ring Switch Features
Overview
The Safety Ring Switch has all the networking capability of a typicalunmanaged switch plus some advanced capability that you would only findin a managed switch. Like an unmanaged switch, the Ring Switch is “plugand play” meaning that it can be used right out of the box - without any
user configuration. This includes the ring functionality, which is alreadypre-configured in the switch. For most applications this is all that isneeded. For advanced applications you can use the Safety Ring Switch
Tools (Windows software utility) to enable some advanced capabilities
such as priority queuing for prioritizing your traffic, message rate filteringfor broadcast storm protection and port mirroring for diagnostics.
Important Note: Only use Safety Ring Switches when connecting switches
in a ring. The Safety Ring Switches use a specialized high-speed ringalgorithm that only they will understand. Otherwise, these Ring Switches
are fully IEEE 802.3 compatible.

Ring setup & operation
For ring operation in most applications, no user configuration is necessary.
The Safety Ring Switches can be ordered pre-configured with 1 or morepairs of ports setup for ring operation. Just connect the ring-configured
ports of your Ring Switches in a ring by connecting the last switch back to
the first. Make sure you use only the ring configured ports for your ringconnections. The non-ring ports should be used to connect to yourEthernet devices such as ArtNet nodes, light or sound desks, soundconvertors, etc.

Safety Ring Switch

Page 13 of 31

Ring algorithm and performance
The Safety Ring feature utilizes a special algorithm that assures very fast
recovery times. Each Safety Ring switch utilizes the special high-speed
algorithm to keep track of the health of the ring. In a healthy ring (acomplete ring), one ring switch will be automatically picked to act as amaster (switch with lowest MAC address) for the ring network.
Alternatively, you can designate one of your ring switches to be themaster using the Ethernet Switch Tools. It is the master switch’s job todetermine which one of its local ring ports are to be in the forwarding or
backup state. The ring port chosen to be in the backup state is where thebackup segment of the ring will be. By default, the ring port with thehigher port number will become the backup port.
All ring switches in the ring must have a way to keep track of each otherin case a failure in communication occurs along the ring. To keep track of
the health of the ring, the Ring switches periodically send test messages
to each other. Therefore, when a ring gets “cut” at a certain location, theRing switches will know and they will take the appropriate action to bring
the network back online. The time that it takes for the last Ring switch to“know” and take appropriate action to rectify the communication problem
will be when the link loss “recovers”.
Recovery time can be estimated by multiplying 5 mS times the number ofswitches, and then adding 30 mS (for loss of link errors) or 60 mS (formessage loss errors). For example, a ring of 10 switches would have arecovery time of 80 mS for the typical loss of link type errors.

Master switch selection
As mentioned above, the ring switch with the lowest MAC address willautomatically become the master and block one of its ports (highest
number port). Alternatively, you can designate one of your ring switches
to be the master using the Ethernet Switch Tools. There is a simple checkbox where you can select “Automatic” or “This Switch” for the master ringswitch selection. This advanced capability allows you to control where thebackup port will be in your network. The ring switch to be designated themaster must be running firmware v0103 or newer. Only the ring switchthat is designated the master needs to be running the newer firmware. Allother ring switches can be running older firmware. It is recommended that
only one ring switch be designated as the master. If more than one isdesignated as the master then the one with the lowest MAC address will
prevail.

Safety Ring Switch Tools
In some applications it may be desirable or required to adjust the Ring
Switches parameters for proper or best operation. A Microsoft Windows
software utility called “Safety Ring Switch Tools” is provided to make theseadjustments. Using the “auto-find” feature in the utility, you will be able toPage 14 of 31

Safety Ring Switch

pick from a list of detected Ring Switches and load custom configurations
via Ethernet. The auto-find feature eliminates the hassle of loading via a
serial connection and the overhead time spent assigning IP addresses.
Refer to the online help for details on using the Safety Ring Switch Tools.
IMPORTANT NOTE: Your computer must be on the same local network as the Ring
Switch for the Ethernet Switch Tools to operate properly. Also, your computer must haveupdated Raw Ethernet Socket (WinPcap) support installed. When installing the Ethernet
Switch Tools, the installation program will call the WinPcap installation program.

Port Configuration
Safety Ring Switches auto-negotiate port settings. In most applications
port settings are best left in the default "Auto" connection mode. For
special situations, the ports can be "Fixed" to restrict communications to
only 10, or 100 Megabits per second, with either half or full duplex. Flowcontrol can be enabled or disabled as well. Port configuration settings areadjustable using the Safety Ring Switch Tools.

Fault tolerant rings
A network backbone wired in a ring type topology is one of the best
choices for a fault-tolerant network. By default, Ring Switches may befactory preset to have zero, one, or two rings enabled. Factory presetting
a ring configuration skips the step of using the Ethernet Switch Tools toenable your rings so you can have the convenience of “plug and play”
operation.
To change the ring configuration in the switch, simply launch the Safety
Ring Switch Tools and choose the desired pair of ports for your new
enabled ring. The Ring LED will be lit if all rings (one or two) that are
enabled in this switch have continuous ring integrity.
For a ring to function, all switches in the path of the ring must have Safety
Ring support. Do not connect rings within rings. Only simple nonoverlapped rings are allowed. Two active rings cannot share a network
segment. It is possible to join two rings together by configuring two rings
in a single switch. The ports used for each ring must be distinct, so thatno network segment is shared by both rings. See for ring wiring examples
and guidelines.

Message rate filtering(Broadcast storm protection)
Poorly configured applications and devices or malicious users can flood
your network with broadcast packets that are forwarded to all ports andcan quickly consume most of a network’s bandwidth. The Safety Ring
Switch provides protection against broadcast storms by limiting thequantity of broadcast and multicast messages. This protection is disabled
by default because broadcast is used by most light and sound protocols.

Safety Ring Switch

Page 15 of 31

Priority queuing(Traffic Prioritization using QoS, CoS, ToS/DiffServ)With priority queuing configured in the Ring Switch, low priority data will
not interfere with your time critical data again. Network traffic can beprioritized to achieve the performance that time-sensitive data demands.
Refer to the Safety Ring Switch Tool’s on-line help for more informationand details on configuring priority queuing.

Port mirroring
This advanced diagnostic capability allows messages from one or more
ports to be copied to another port. Then a port analyzer or “sniffer”
program can be used to monitor the traffic without affecting the operationof the switch. Configuring the Safety Ring Switch for port mirroring isdone through the Safety Ring Switch Tools. See the on-line help for
details.
Note: With firmware 0103 or newer, only one monitor (destination) port isallowed. However, multiple source ports can be chosen.

Page 16 of 31

Safety Ring Switch

Ring configurations
Configuring rings in your switch
First and foremost, make sure that ring operation is enabled for theappropriate ports. In other words it is required to tell the Ring Switch
what ports it is going to use as ring ports (unless the Ring Switch waspurchased with rings pre-configured). Never wire a Ring Switch in a ring
topology without having the ports that are used in the ring configured asring ports (See diagram below).

Valid ring topologies
Below are examples of how you should wire your Ring Switches together.
In general, you should keep your topology simple.

Safety Ring Switch

Page 17 of 31

Invalid ring topologies
The examples below are invalid ring topologies. Do NOT connect Ring
Switches in the ways shown below, as they will lead to unpredictablenetwork performance. Paths indicated by the color red create unintended
rings (see unintended rings example below).

Page 18 of 31

Safety Ring Switch

Unintended ring example
Refer to the diagram below. In this example, the top and bottom Ring
Switches have been software configured for two rings each. The left andright Ring Switches have been software configured for one ring each. The
physical connections for the two rings are shown in blue and orange.
Since the rule for configuring Ring Switches is to make sure that each
Ring Switch knows about all rings that are attached to it, it would appear
that the example below is legal. However, this is not the case. There are
actually more than two ring paths that were created. There are multiple
paths that traffic can use to move from the top Switch and back to the top
Switch. The same applies to the bottom Switch. These unintended Ring
paths that top Switch and bottom Switch don’t know about are labeled as
Unintended Rings A, B, C, and D.
Since the top Ring Switch and bottom Ring Switch don’t know about these
extra ring paths, they aren’t included in A or B’s ring algorithm. Paths thatare not included in the ring algorithm will result in harmful broadcast
storms, as will happen when conventional switches are connected in a ring
topology.

Safety Ring Switch

Local and remote status monitoring
Switch status
You can keep track of the status of your Ring Switches at all times. To
check the status of a Ring Switch visually, you can monitor the Ring
Switch’s indicator LEDs. To monitor the status remotely, you can use
Modbus over Ethernet (UDP).

Visual status monitoring
The status of your Safety Ring Switches can be easily ascertained bysimply looking at their LED indicators. The LEDs can be used to quickly
see the status or to locate a network problem. See for details on the LED
indicators.

• Port Status (ACT/LNK LED)
After all Ethernet and/or fiber connections are made, check theLED’s corresponding to the ports that each of the devices areconnected to. Ensure that for each port that is in use, thelink/activity LED is on or blinking. If a port link/activity LED is off, goback and check for connectivity problems between that port and the
network device connected to that particular port. In addition, thespeed LED should indicate the speed for which your device isconnected at (off – 10Mbps, orange – 100Mpbs).

• Power & Switch Status (OK LED)
The Ring Switch has an OK LED that indicates the power andoperational status. It is ON solid green when there are no errors. It
Page 20 of 31

Safety Ring Switch

will go ORANGE if a ring break is detected. The OK LED will also
flash if the switch is being “winked”, is in the boot-up mode, or aninternal error was detected.

• Ring Status (Ring LED)
The Ring Switch has a Ring LED that indicates the status of your ringconnections. It is ON solid when all rings handled by the switch havecontinuous integrity. It will be blinking if there is broken ring
segment but all adjacent switches are responding. It will be OFF if
the switch is not configured for any rings. The ring LED will Blip
(mostly OFF, with a quick ON) when a configured ring has beenbroken and the break is local to one of the ports of the switch.
Typically the network with the fault will be between the two switcheswith Ring LEDs in the Blip state. This makes tracking down faults
quick and simple.

Remote status monitoring
There are two ways to remotely monitor the status of your Safety Ring
Switch network.
The first method is to use the Safety Rings Switch Tool’s status display.
This display will show the status of the selected Ring Switch by providing
details such as port, power, and ring states. Find more details about how
to use this display by referring to the Safety Ring Switch Tool’s on-line
help.
The second method that can be used for determining the state of yourRing Switch network is via Modbus UDP. See the Modbus UDP topic below
for detailed information about how to take advantage of this feature.

• Modbus/UDP
Through Modbus UDP (Note: TCP is not supported), you canremotely monitor the status of the Safety Ring Switch. Using the
Safety Ring Switch Tools, the Ring Switch can be configured as a
Modbus slave station with its own Modbus station number and IP
address.
The Ring Switch has a set of predefined Modbus registers for status
reporting. Refer to the table below for the register assignments.

NOTE: It is recommended that you keep the poll time of yourModbus master driver or hardware device to a reasonable rate. If
you poll a Ring Switch at a rapid rate, the performance of the switch
may be reduced. The fastest poll time you should run will depend on
the application. As a guideline, a poll time of 500 mS or greater
should not adversely affect the performance of your Ring Switch.

Safety Ring Switch

General Features and Capabilities
Features & Capabilities
This section explains the primary Ethernet and fiber capabilities of the
Ring Switch.
10BaseT and 100BaseT Auto-detection
Standard Ethernet (10BaseT) has a maximum speed of 10 Mbps (halfduplex mode) or 20 Mbps (full duplex mode). Fast Ethernet (100BaseT)
has a maximum speed of 100 Mbps (half duplex mode) or 200 Mbps (fullduplex mode). The 10/100 RJ45 ports automatically support two speeds.
100BaseF (multimode and singlemode) fiber optic port
The fiber optic port found is classified as 100BaseF and supports 100 Mbps
operation. Multimode allows for multiple wavelengths over a cable with acore diameter of typically 50 or 62.5 microns. The maximum distance formultimode is up to 2 km.
2K or 8K MAC addresses with automatic learning, aging andmigration
Each Ethernet device inserts its unique “MAC” address into each message
it sends out. The port on the switch used for a given MAC address is
automatically learned when a frame is received from that address. Oncean address is learned, the switch will route messages to only theappropriate port, instead of broadcasting messages out all ports like ahub. A time stamp is also placed in memory when a new address islearned. This time stamp is used with the aging feature, which will remove
unused MAC addresses from the table after 300 seconds. If a device
moves, the associated port on the switch will be changed (migrated) as
needed. Up to 8,192 MAC addresses can be stored and monitored at any
time.
3.2 Gbps combined bandwidth
The fast Ethernet switches have 3.2 Gbps. This means that they can
support full duplex communications on all ports at the same time.
Auto-crossover (auto-mdi/mdix)
The RJ45 ports of the Safety Ring Switch will automatically detect thecable type (straight-thru vs. cross-wired) and re-configure themselves
accordingly.
Auto-polarity
The auto-polarity feature corrects reversed polarity on the transmit andreceive twisted pair.
Automatic power saving
If there is no cable on a port, most of the circuitry for that port is disabled
to save power.
Safety Ring Switch

Page 23 of 31

Auto-sensing speed and flow control
The RJ45 ports of the Safety Ring Switch will auto-negotiate with theconnected device to determine the optimal speed and flow control for each
port.
Back pressure for half-duplex
The Safety Ring Switch will apply “back pressure” when necessary withhalf-duplex operation. This “back pressure” will reduce congestion on busy
networks.
Broadcast storm protection
Each port can be configured to filter out undesirable broadcast andmulticast messages.
Buffering
SRAM is used for buffering the messages. The Ring Switches have 1 Mbits(128 Kbytes). The buffer size is automatically allocated for each port asnecessary.
Flow control
These switches automatically support flow control frames on both thetransmit and receive sides. Back-pressure flow control for half-duplex
ports and pause-frame flow control for full-duplex ports.
Forwarding
These switches support store and forward mode. They will forward
messages with known addresses out only the appropriate port. Messages
with unknown addresses, broadcast messages, and multicast messages
will get forwarded out all ports except the source port.
Full / Half duplex operation
The RJ45 ports of these switches support both full and half duplex
operation. The fiber optic port(s) are full duplex but can be interfaced todevice with half or full duplex.
Illegal frames
Illegal frames as defined by IEEE 802.3 will be dropped. This includes
short frames, long frames, CRC error frames and alignment error frames.
IEEE 802.3 compliant
Safety Ring Switches strictly abide to the IEEE 802.3 standard for10BaseT, 100BaseT and 100BaseF Ethernet communications.
Latency
The typical latency of a message is 5 microseconds (@ 100 Mbps) plus theframe time. The latency is the time it takes a message to be routed
internal to a switch from one port to another. This time is highly

Safety Ring Switchdependent on the amount of network activity, the speed and the features
enabled in the switch.
Non-blocking
This means that the switches offer the best in performance and arecapable of full-wire speed transmissions.
Port Mirroring
Powerful diagnostic mode that lets you map messages between ports.
Plug and play
This means that most functions or features of these switches areautomatic and that there are minimal or no optional parameters that need
to be set. Just plug in your Ethernet cables, apply power, and the unit will
immediately begin to operate. The Ring Switches can even be factory preconfigured to your exact needs.
Priority queuing or Traffic Prioritization
The Ring Switches support QoS (Quality of Service), CoS (Class ofService), ToS (Type of Service), and DS (Differentiated Services)mechanism for ensuring the priority traffic is handled properly. Theseadvanced parameters can be set via the configuration utility.
Protocol independent
These switches will work with all popular Ethernet protocols and networks
such as TCP/IP, the Internet (IP), UDP, NetBEUI, and many more. It is
compatible with all protocols that run over standard Ethernet (IEEE802.3). In fact, it will support packets of different protocols
simultaneously.
