Verify the Power LED stays ON (GREEN).
Notes:
Only 1 power supply must be connected to power for minimal operation. For redundant power
operation, V1 and V2 inputs must be connected to separate DC Voltage sources. This device will
draw current from both sources simultaneously. Use 16-28 gauge wire when connecting to the
power supply.
The Fault pins on the power connector can be used for an alarm contact. The current carrying
capacity is 1A at 24VDC. It is normally open and the relay closes when a fault condition occurs.
These pins can be used to connect an external warning device such as a light in order to provide an
external alarm. The conditions for generating a fault condition (closing the relay) can be configured
through software.
Recommended 24V DC Power Supplies, similar to: N-Tron’s P/N NTPS-24-1.3 (NOTE: Not appropriate
for use with M12, POE, and HV models.):

Connecting the Unit
For FX/FXE units, remove the dust cap from the fiber optic connectors and connect the fiber optic cables.
The TX port (located on the bottom connector) on the FX/FXE models should be connected to the RX port of the
far end station. The RX port (located on the top connector) on the FX/FXE versions should be connected to the
TX port of the far end station.
For 10/100 Base-TX ports, plug a Category 5E twisted pair cable into the RJ45 connector. Connect the
other end to the far end station. Verify that the LNK LEDs are ON once the connection has been completed.
To connect any port to another device (end node, Switch or Repeater), use a standard Category 5E straight
through or crossover cable with a
minimum length of one meter and a
maximum length of 100 meters.
N-Tron recommends the use of premanufactured Cat5E cables to ensure the
best performance. If this is not an option
and users must terminate their own ends
on the Cat5E cables; one of the two color
coded standards shown to the right should
be utilized. If a user does not follow one
of these two color code standards then the
performance and maximum cable distance
will be reduced significantly, and may
prevent the switch from establishing a
link.
Warning: Creating a port to port connection on the same switch (i.e. loop) is an illegal operation and
will create a broadcast storm which will crash the network!
(Revised 2015-09-28) Page 15 of 161
N-TRON SWITCH GROUNDING TECHNIQUES
The grounding philosophy of any control system is an integral part of the design. N-Tron switches are
designed to be grounded, but the user has been given the flexibility to float the switch when required. The
best noise immunity and emissions (i.e. CE) are obtained when the N-Tron switch chassis is connected to
earth ground via a drain wire. Some N-Tron switches have metal din-rail brackets that can ground the
switch if the din-rail is grounded. In some cases, N-Tron switches with metal brackets can be supplied with
optional plastic brackets if isolation is required.
Both V- legs of the power input connector are connected to chassis
internally on the PCB. Connecting a drain wire (shown in green) to
earth ground from one of the V- terminal plugs as shown here will
ground the switch and the chassis. The power leads from the power
source should be limited to 3 meters or less in length.
As an alternate, users can run a drain wire (shown in green) & lug from any of
the Din-Rail screws or empty PEM nuts on the enclosure. When using an
unused PEM nut to connect a ground lug via a machine screw, care should be
taken to limit the penetration of the outer skin by less than 1/4 in. Failure to do
so may cause irreversible damage to the internal components of the switch.
Note: Before applying power to the grounded switch, you must use a volt meter
to verify there is no voltage difference between the power supply’s negative
output terminal and the switch chassis grounding point.
If the use of shielded cables is required, it is generally recommended to only connect the shield at one end to
prevent ground loops and interfere with low level signals (i.e. thermocouples, RTD, etc.). Cat5e cables
manufactured to EIA-568A or 568B specifications are required for use with N-Tron Switches.
In the event all Cat5e patch cable distances are small (i.e. All Ethernet devices are located in the same local
cabinet and/or referenced to the same earth ground), it is permissible to use fully shielded cables terminated
to chassis ground at both ends in systems void of low level analog signals.

Overview of Advanced Features
Mode of Operation
Each port on the switch can be configured into different modes of operation as shown below:
Copper Ports: 100Base Fiber Ports: 1000Base Copper/Fiber Ports:
- Half Duplex - Full Duplex - Full Duplex
- Full Duplex
- Auto Negotiation
Half Duplex
In half duplex mode, the CSMA/CD media access method is the means by which two or more stations share
a common transmission medium. To transmit, a station waits (defers) for a quiet period on the medium (that
is, no other station is transmitting) and then sends the intended message in bit-serial form. If, after initiating
a transmission, the message collides with that of another station, then each transmitting station intentionally
transmits for an additional predefined period to ensure propagation of the collision throughout the system.
The station remains silent for a random amount of time (back-off) before attempting to transmit again.
Full Duplex
Full duplex operation allows simultaneous communication between a pair of stations using point-to-point
media (dedicated channel). Full duplex operation does not require that transmitters defer, nor do they
monitor or react to receive activity, as there is no contention for a shared medium in this mode.
Auto Negotiation
In Auto Negotiation mode, the port / hardware detects the mode of operation of the station that is connected
to this port and sets its mode to match the mode of the station.
Port Mirroring
A Mirroring Port is a dedicated port that is configured to receive the copies of Ethernet frames that are being
transmitted out and also being received in from any other port that is being monitored.
Port Trunking
Port Trunking is the ability to group two network ports to increase the bandwidth between two machines
(switch or any work station). This feature allows grouping of high-speed connectivity and provides
redundant connection between switches, so that a trunk can act as a single link between the switches.
Quality of Service (QoS)
Quality of service (QoS) refers to resource reservation control mechanisms. Quality of service is the ability
to provide different priority to different applications, users, or data flows. Quality of service guarantees are
important if the network capacity is insufficient, especially for real-time streaming multimedia applications
such as voice over IP, online games and IP-TV, since these often require fixed bit rate and are delay
sensitive, and in networks where the capacity is a limited resource, for example in cellular data
communication. In the absence of network congestion, QoS mechanisms are not required.
(Revised 2015-09-28) Page 19 of 161
Each of these three QOS methods below is included or not based on the settings on the relevant browser
page:
1) Force High Priority (Port Based),
2) IEEE802.1p (Tagged QOS), or
3) DSCP (differentiated services code points) (RFC 2474).
When Force High Priority is enabled, the port based priority is included in the decision for all ports and all
frames received on a port will use the default QOS priority for that port in the decision. For example, if it is
desired to have ingress frames on a port egress to the highest priority transmit queue regardless of other
factors, then enable Force High Priority and set the port's Default Port Priority to 7.
Virtual LAN
The switch provides support for setting up tagged Virtual LANs (Local Area Networks). A port may belong
to any number of Virtual LANs. The VLAN membership of a device is determined by the VLAN(s) that
have been defined for the port to which the device is connected. If a device should move from one port to
another, it loses its current VLAN membership and inherits that of the new port it is connected to.
VLANs facilitate easy administration of logical groups of devices that can communicate as if they
were on the same LAN. Traffic between VLANs is restricted, unless the ports are explicitly configured
as overlapping VLANs. Switches forward unicast, multicast, and broadcast traffic only on LAN segments
that serve the VLAN to which the traffic belongs.
A Default Virtual LAN (VID=1) exists to which a port, which is not a member of any other Virtual LAN,
will belong. This allows the switch to operate as a ‘normal’ switch when it is used in a network. A port is
automatically removed from the Default VLAN when it is reconfigured to belong to another Virtual LAN,
because that is the most common operation. But, if desired, the port can be included in VLAN 1 by
configuring VLAN 1 last.
If switch ports are configured to transmit and receive untagged frames, end devices are able to communicate
throughout the LAN. Using Tagged VLANs, the switch has the ability to take non-tagged packets in some
ports, add a VLAN tag to the packet and send it out tagged ports on the switch. The VLANs can also be
configured to accept tagged packets in tagged ports, strip the tags off the packets, and send the packets back
out other untagged ports. This allows a network administrator to set up the switch to support devices on the
network that do not support VLAN Tagged packets. The administrator can also set up the ports to discard
any packets that are tagged or to discard any packets that are untagged based on a hybrid VLAN of both
tagged and untagged ports, and using the VLAN Ingress Filter on the switch.
For each switch port there is one and only one PVID (port VLAN ID) setting. If an incoming frame is
untagged and untagged frames are being accepted, then that frame will inherit the tag of the PVID value for
that port. Subsequent switch routing and treatment will be in accordance with that VLAN switch map. By
configuring PVIDs properly and configuring for all frames to exit untagged, the switch can achieve a ‘port
VLAN’ configuration in which all frames in and out can be untagged, thus not requiring external devices to
be VLAN cognizant.
To understand how a VLAN configuration will perform, first look at the port on which the frame enters the
switch, then the VLAN ID (if the frame is tagged) or the PVID (if the frame is untagged). The VLAN
defined by the VID or PVID defines a VLAN group with a membership of ports. This membership
determines whether a port is included or excluded as to frame egress from the switch.
(Revised 2015-09-28) Page 20 of 161
The 714FX6 Series switch also has the ability to allow overlapping VLANs. Overlapping VLANs give
the user the ability to have one or more ports share two or more VLAN groups. For more information and
examples on how this could be implemented, please see the ‘VLAN Configuration Examples’ in this
document, and/or our website’s technical documents. Note that RSTP on overlapping VLANs is not
supported and the system will automatically disable RSTP on all but the lowest VID VLANs that have
overlapping ports.
Rapid Spanning Tree Protocol
The Rapid Spanning Tree Protocol as specified in IEEE 802.1D-2004 is supported. One Spanning Tree per
non-overlapping VLAN is supported. The Rapid Spanning Tree Protocol (RSTP) supersedes the Spanning
Tree Protocol (STP) which was described in IEEE 802.1D-1998. The RSTP is used to configure a simply
connected active network topology from the arbitrarily connected bridges of a bridged network. Bridges
effectively connect just the LANs to which their forwarding ports are attached. Ports that are in a blocking
state do not forward frames. The bridges in the network exchange sufficient information to automatically
derive a spanning tree.
RSTP allows for much quicker learning of network topology changes than the older STP. RSTP supports
new and improved features such as rapid transition to forwarding state. RSTP also sends out new BPDUs
every hello time instead of just relaying them. RSTP interoperates with older STP switches by falling back
to the older STP when the older BPDUs are detected on bridge ports. The user can also manually configure
bridge ports to use the older STP when desired.
SNMP Traps
The 714FX6 Series switch supports up to 5 SNMP Trap Stations to which SNMP Traps will be sent. The
switch supports five standard traps; Link Up, Link Down, Cold Start, Warm Start and Authentication Errors.
SNMP Traps will be sent to all the trap stations configured on the switch when the corresponding trap is
enabled.
IGMP Snooping
IGMP Snooping is enabled by default, and the switch is Plug and Play for IGMP. IGMP snooping provides
intelligent network support for multicast applications. In particular, unneeded traffic is reduced. IGMP
Snooping is configured via the web console and if enabled, operates dynamically upon each power up.
Also, there can be manual only or manual and dynamic operation. Note that “static multicast group
address” can be used whether IGMP Snooping is enabled or not.
IGMP Snooping will function dynamically without user intervention. If some of the devices in the LAN do
not understand IGMP, then manual settings are provided to accommodate them. The Internet Group
Management Protocol (IGMP) is a protocol that provides a way for a computer to report its multicast group
membership to adjacent ‘routers’. In this case N-Tron 714FX6 series switches provide router-like
functionality. Multicasting allows one computer to send content to multiple other computers that have
identified themselves as interested in receiving the originating computer's content. Multicasting can be used
to transmit only to an audience that has joined (and not left) a multicast group membership. IGMP version 2
is formally described in the Internet Engineering Task Force (IETF) Request for Comments (RFC) 2236.
IGMP version 1 is formally described in the Internet Engineering Task Force (IETF) Request for Comments
(RFC) 1112. The 714FX6 series supports v1 and v2.
(Revised 2015-09-28) Page 21 of 161
N-Ring
N-Ring is enabled by default, and the switch is Plug and Play for N-Ring except that initially one must
enable an N-Ring enabled device to be the N-Ring Manager for a given N-Ring. Subsequently, N-Ring
operates dynamically upon each power up. Using N-Tron's proprietary N-Ring technology offers expanded
ring size capacity, detailed fault diagnostics, and a standard healing time of 30ms. The N-Ring Manager
periodically checks the health of the N-Ring via health check packets. If the N-Ring Manager stops
receiving the health check packets, it times out and converts the N-Ring to a backbone within 30ms. When
using all N-Ring enabled switches in the ring, a detailed ring map and fault location chart is also provided
on the N-Ring Manager’s web browser. N-Ring status is also sent from the N-Ring Manager to the N-View
OPC Server to identify the health status of the ring. Up to 250 N-Ring enabled switches can participate in
one N-Ring topology. Switches that do not have N-Ring capability may be used in an N-Ring, however the
ring map and fault location chart cannot be as detailed at these locations.
N-Link
The purpose of N-Link is to provide a way to redundantly couple an N-Ring topology to one or more other
topologies, usually other N-Ring topologies. Each N-Link configuration requires 4 switches: N-Link
Master, N-Link Slave, N-Link Primary Coupler, and N-Link Standby Coupler. N-Link will monitor the link
status of the Primary and Standby Coupler links. While the Primary Coupler link is healthy, it will forward
network traffic and the Standby Coupler link will block network traffic. When a problem is detected on the
Primary Coupler link, the Primary Coupler link will block network traffic and the Standby Coupler link will
forward network traffic. While the N-Link Master and Slave are in communication via the Control link,
only one Coupler link (Primary or Standby) will forward network traffic while the other Coupler link will
block network traffic.
CIP
The CIP (Common Industrial Protocol) feature allows N-Tron switches to directly provide switch
information and configuration access to Programmable Logic Controller (PLC) and Human Machine
Interface (HMI) applications via a standardized communication protocol. For example, a PLC may be
programmed to monitor port links or N-Ring status and cause a status indicator to turn red on an HMI if a
port goes link down or if N-Ring has a fault. CIP is formally described in ODVA Publication Number
PUB00001 (Volume 1: Common Industrial Protocol (CIP™)), and Publication Number: PUB00002
(Volume 2: EtherNet/IP Adaptation of CIP). N-Tron provides EDS and ICO files. N-TRON_CIP_Tags.pdf
is for a particular environment, but reveals the tags available.
DHCP
The Dynamic Host Configuration Protocol (DHCP) provides configuration parameters to Internet hosts.
DHCP is built on a client-server model, where designated DHCP server hosts allocate network addresses
and deliver configuration parameters to dynamically configured hosts. DHCP is controlled by RFC 2131.
The N-Tron DHCP Switch can be configured to be a DHCP Client. Alternately the N-Tron DHCP switch
can be configured to be a DHCP Server, a DHCP Relay Agent, or both.
For more detailed information on N-Tron DHCP features, reference: http://www.n-tron.com/tech_docs.php.
Under ‘White papers’, see. “Using DHCP to Minimize Equipment Setup Time”. Under ‘Installation Guides
and User Manuals’ see “DHCP Technical Instructions for 708 / 716/ 7018 / 7506 Series”.
(Revised 2015-09-28) Page 22 of 161
DHCP Client
The switch will automatically obtain an IP assignment from a DHCP Server, or optionally Fallback to a
configured IP assignment if unable to get an IP assignment from a DHCP server. Communication between
the client and server can optionally go through a DHCP Relay Agent.
DHCP Relay Agent
DHCP Relay Agent (Option 82) allows communication between the client and server to cross subnet and
VLAN boundries. It also allows for a device on a specific port to receive a specific IP address and if the
device is replaced, the replacement receives the same IP address as the original device.
DHCP Server
DHCP Server allows DHCP Client devices to automatically obtain an IP assignment. IP assignments can be
set up as a dynamic range of IP addresses available to any client device; or specific IP addresses based on
the clients MAC address, Client ID (Option 61), or Relay Agent connection (Option 82).
LLDP
Link Layer Discovery Protocol (LLDP) is a Layer 2 discovery protocol that allows devices attached to an
IEEE802 LAN to advertise to other devices the major capabilities they have and to store information they
discover in a MIB that can be accessed through SNMP. LLDP is formally described in IEEE Standard -
802.1AB.
Port Security—MAC Address Based
The Port Security feature restricts access to the switch by only accepting dynamically learned MAC
addresses and manually entered MAC addresses as authorized. Dynamically learned MAC addresses are
those that the switch detects on any port while in ‘Learning’ mode. A manually entered MAC address must
designate the ports that the address is authorized on. A non-authorized MAC address will be discarded and
will be shown on the intruder log.

LLDP - Configuration
Mode:
Enables or Disables LLDP on the Switch. Default: Disabled
Transmit Interval:
Specifies the interval at which LLDP frames are transmitted. Default = 30 seconds.
Transmit Hold Multiplier:
Specifies a multiplier on the Transmit Interval when calculating a Time-to-Live value. Default = 4.
Re-Initialization Delay:
Specifies a minimum time an LLDP port will wait before re-initializing after setting the port to disable followed by
setting a port to Tx-Only or Tx/Rx. This prevents excessive Notifications if someone toggles between Disabled and
Enabled on LLDP Port settings. Default = 2 Seconds.
Notification Interval
Specifies the interval between successive Notifications generated by the switch. If a port sends out a notification and
another port tries to send out a notification, the notification will not be sent until the interval expires.
Default = 5 Seconds.
Note: A redundant network topology will have one or more blocking ports to prevent looping and
broadcast storms. LLDP will not receive neighbor information into a blocked port, though the
LLDP information will be transmitted out of a blocked port. Therefore, the switch that has the
blocked port will not know about the neighbor on the other side of the blocked port, but the neighbor
will know about the switch that has the blocked port.

Ports – MAC Security – Intruder Log
The Intruder Log tab displays a list of unauthorized MAC addresses that attempted to access the secured
device. Each intruder entry in the log is unique, and is based on the combination of MAC address, VLAN,
and port. Only the first occurrence of the intruder is listed. The log is ordered by most recent first, based on
the system time. The maximum number of entries is 100. If more than 100 intruders are detected, the
oldest entries are deleted. The log is not saved through a power cycle.
An entry can be individually removed from the log by selecting the associated Delete button. All entries or
entries specific to a port can also be removed from the log by choosing the option in the dropdown list and
then selecting the Clear button.

Ports – Trunking
The Trunking tab under the Ports category displays the following details:
Trunk Ports
This field displays the ports associated with the trunk.
Trunk Status
This configurable field displays the existing status of the trunk. It can be either Enabled/Disabled.
By selecting the Modify button, you can select a trunk group.
Note: RSTP must be disabled in order to use the Trunking feature.
Two ports of the same speed can constitute a valid trunk.
Only 1 Trunk per switch can be created.
All trunk ports must be at the same speed and duplex mode. If a port is not linked, there could be
difficulty as to similar speed and duplex mode. It is best to hard code speed and duplex mode for
each trunking link, at both ends.
Do not use Trunking on an N-Ring manager. Do not connect the N-Ring to actively Trunking ports
on an Auto Member.

Bridging – Multicast Addresses
The Multicast Addresses tab under the Bridging category will display a list of Multicast Group Addresses
that are associated with respective port numbers. This may be used to statically assign a Multicast Group
Address access to a group of ports on the switch.
Following the Add button on the page above, the administrator must enter a valid Multicast Group Address
and associate it with a port number or list on the switch. Once the administrator clicks on the Add button,
the changes will take effect instantly.
Note: If there are multiple ports on different VLANs, the 714FX6 will apply the static multicast address to
the lowest VLAN-ID that is associated with one of the ports assigned to the static multicast address.
So if the lowest VLAN-ID contains all the ports assigned to the static multicast address (an umbrella
VLAN), it will function for all those ports with no problems. This can be achieved with overlapping
VLANs.

Bridging – Show MAC by Port
This feature shows the MAC addresses of devices connected to each switch port and the IP Addresses
associated with the MACs. The browser page ‘View MAC by Port’ shows the MAC for the device found
on each port, and the IP for the MAC presented if available. If more than one device is on that port, then the
lowest alphanumeric of those MAC addresses is shown and underlined.
The ‘Active IP Probe’ field is configurable using the ‘Modify’ button, and also displays the existing
Enabled or Disabled status of this feature. The default is disabled. When disabled the switch generates no
ethernet traffic for this purpose, but can still present some information gathered passively.
(Revised 2015-09-28) Page 73 of 161
The ‘IP’ field shows an Auto-detected or manually entered IP address. If there is a MAC address for the port
and an IP address was not discovered there is an ‘Assign IP’ button to allow the user to enter an IP address.
If ‘Active IP Probe’ is enabled, manually entered IP values are underlined and validated. A validated IP for
that MAC is presented in green and if validation fails the IP will be red and underlined. Note that some
devices do not have an IP Address, and that some devices that do have an IP Address may not respond to the
methods used to detect their IP Address.
Invoking the ‘Assign IP’ button on the example above, the administrator will be presented with a form in
which to enter a manually assigned IP, as below:
When an IP has been manually entered a button is provided to ‘Delete IP’, and invoking it will allow the
administrator to delete the manual association of an IP to that MAC.

RSTP – Configuration Continued…
The configuration screen for the VLAN that was previously selected will look like the example below. Here
the administrator can make changes such as the Hello Time, Forward Delay, Max Age, Priority, and the
Status of RSTP on that VLAN. The administrator or user can see the current RSTP status of the ports on
that VLAN by clicking on the ‘here’ link to view RSTP Port Configuration at VLAN#.
Note: It is recommended that RSTP rings consist of RSTP capable switches.
Trunking must be disabled in order to use RSTP.
Do not create redundant links unless either RSTP or N-Ring is enabled.
RSTP on overlapping VLANs is not supported and the system will automatically disable RSTP on all
but the lowest VID VLANs that have overlapping ports.

Following the link for the view RSTP Port Configuration at VLAN#, the administrator or user can see the
current RSTP status of the ports on that VLAN. This will show information such as the Path Cost and the
Port State. If the switch sees a redundant path it will put the port with the highest Path Cost into Blocking
mode where it will discard packets coming in on that port. In the example below, TX2 is a redundant port
with port TX1, therefore TX1 is forwarding and TX2 is discarding.

IGMP – RFilter
The ‘rfilter’ (Router Multicast Data Filter) function allows you to choose whether or not DATA frames
with KNOWN group multicast addresses are sent to the ‘router’ ports (links to other switches). Control
packets (Join, Leave) will be sent to the router(s) regardless of this setting. “KNOWN” is known from
dynamic IGMP Snooping operations.
The factory default is that the Router Multicast Data Filter is enabled for all ports, so any router ports do
NOT get DATA frames with KNOWN multicast destination addresses unless a join to a specific multicast
address has been received on that port. Joins override an rfilter.
If rfilter is disabled, router ports do get DATA frames with KNOWN multicast destination addresses
Rfilter can be set for individual ports: any, all, or none. For each port, rfilter will have an impact only if that
port is manually or dynamically chosen as a router port.

default, N-Ring is in Auto Member mode and the N-Ring Aging Time is 20 seconds.
Following the Modify button on the above example, the administrator will see a list of configurable fields
for the N-Ring configuration, as below.
The N-Ring Aging Time has a default of 20 seconds and is separate from the Bridging Aging Time. N-Ring
Aging Time is used when the switch is an N-Ring Manager or becomes an active N-Ring Member, and in
either case N-Ring status includes for example:
“Switch is currently using N-Ring Aging Time = 20 Seconds”
Once these fields are filled in to meet the needs of the administrator’s network, the changes may be saved by
clicking the Update button at the bottom of the page.
NOTES:
1. N-Ring Manager cannot have RSTP or Trunking enabled.
2. RSTP & N-Ring are different modes and cannot share links or segments along those lines.
See the examples in the RSTP configuration section.
3. Do not use Trunking on an N-Ring manager. Do not connect the N-Ring to actively Trunking
ports on an Auto Member.
4. Do not create redundant links unless either RSTP or N-Ring is enabled.
5. Any one 714FX6 can only participate in one N-Ring.
6. N-Ring copper ports must be run at 100Mb full duplex, including the default ‘autonegotiate’ as
long as all switches in the ring support 100Mb full duplex.

N-Ring – Configuration, Continued…
The “N-Ring Mode” is one of three, as below:
If N-Ring Mode is “Manager”, then a pull-down allows selection of available ports TX1/TX2, or FX1/FX2
(on 714FX6) as N-Ring ports.
(Revised 2015-09-28) Page 90 of 161
N-Ring – Configuration, Continued…
If N-Ring Mode is “Manager”, then VLAN ID can be set to a unique VLAN id (1 ~ 4094). Default is 3333.
If N-Ring Mode is “Manager”, then a pull-down allows selection as to whether the N-Ring ports are
members of the VLAN’s Tagged or Untagged ports. Default is Tagged.
Once these fields are filled in to meet the needs of the administrator’s network, the changes may be saved by
clicking the Update button at the bottom of the page.
NOTES:
1. Since VLANs are implemented for security reasons as well as traffic flow, N-Ring only makes
minimal changes. It is up to the administrator to ensure that VLANs are configured correctly on the
N-Ring manager and all N-Ring members.
2. When the N-Ring manager and all N-Ring Members are in defaults, changing the N-Ring manager
to use a Tagged VLAN requires no user interaction to allow non-ring traffic to pass through the ring.
This works because changing to a Tagged VLAN does not remove the ring ports from the default
VLAN.
3. When the N-Ring manager and all N-Ring Members are in defaults, changing the N-Ring manager
to use an Untagged VLAN other than VID 1, requires the administrator to add non-ring ports to the
N-Ring VLAN to allow non-ring traffic to pass through the ring. This occurs because the N-Ring
ports must be removed from VID 1 because an untagged port may only be a member of one VLAN.

topologies, usually other N-Ring topologies. Each N-Link configuration requires 4 switches: N-Link
Master, N-Link Slave, N-Link Primary Coupler, and N-Link Standby Coupler.
Standard N-Link Configuration (Example):
For convenience, a diagram similar to the above is provided in the switch’s browser help for N-Link.

Complex N-Link Configuration (Example):
Configuration Notes:
The Master and Slave must be part of the N-Ring topology.
If using default configuration choices, the administrator only needs to configure the N-Link Master.
The N-Link Slave and both Coupler switches will auto-detect any needed configuration.
If not using default configuration choices, the administrator may also need to configure the Default
Coupler port on the N-Link Slave.
There must be a direct link between the Master and Slave Control ports. Use of media converters or
other switches is not supported.
There must be a direct link between the Master and Slave Partner ports. Use of media converters or
other switches is not supported.
There must be at least one other switch, besides the Master and Slave, that supports N-Link on the
N-Ring.
N-Link will only support a single point of failure. Multiple points of failure and misconfiguration
are not supported and may cause a network storm under some circumstances.
Configuration Steps to redundantly couple 2 N-Ring networks:
1. Ensure the Coupler and Control cables are disconnected at this point.
2. Get Both N-Rings working with a status of OK.
3. Configure N-Link Slave: Ensure that the N-Link Slave is set to Auto Configure and select a Default
Coupler Port. Save Configuration.
4. Configure N-Link Master: Select the Control and Coupler ports. Save the Configuration.
5. Connect the Control Link cable. Ensure that the Slave switch status now shows a state of “Slave”
6. Connect the Coupler Link cables.
7. Check N-Link status by selecting the N-Link Status View page.

N-Link – Configuration, Continued…
The Configuration tab under the N-Link category will display the configuration settings. By default, NLink is in Auto Configure mode and will use TX4 as the Default Coupler port.
Following the Modify button on the above example, the administrator will see a list of configurable fields
for the N-Link configuration, as below.
The port configured as the Default Coupler Port will be used as the Standby Coupler port if the switch
detects an N-Link Master and becomes an N-Link Slave.
Once these fields are filled in to meet the needs of the administrator’s network, the changes may be saved by
clicking the Update button at the bottom of the page.
