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 on the FX/FXE models should be connected to the RX port of the far end station. The RX port
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!

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 (20 gauge minimum size 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
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 & 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 (NOTE: Recommend #6 32X1/4"
Phillips pan head zinc screw). 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:
- Half 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 2010-7-30) Page 18 of 154
Each of these three QOS methods below is included or not based on the settings on the relevant browser
page:
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.
The 700 Series switch also has the ability to allow overlapping VLANs. Overlapping VLANs give the user
(Revised 2010-7-30) Page 19 of 154
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 700 Series switch supports up to 5 SNMP Trap Stations to which SNMP Traps will be sent. The switch
supports four standard traps; Link Up, Link Down, Cold Start and Warm Start. SNMP Traps will be sent to
all the stations configured on the switch if a port Link goes up or down, when the switch first powers up and
when the switch is reset.
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 700 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 700 Series supports v1 and v2.
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
(Revised 2010-7-30) Page 20 of 154
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‖.
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.
(Revised 2010-7-30) Page 21 of 154
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.

Administration – System, Continued…
By selecting the Modify button, you will be able to change the switch‘s IP Configuration, Client ID, IP
Address, Subnet Mask, Gateway, Name, Contact information, and the Location of the switch through the
web management features, depending on the IP Configuration. It is recommended to change the TCP/IP
information through the Command Line Interface (CLI) initially, but it defaults to the following:
IP Configuration – Static
IP Address – 192.168.1.201
Subnet Mask – 255.255.255.0
Gateway – 192.168.1.1
If the IP Configuration mode is set to DHCP and the Fallback IP address is changed from the default IP
address, then the switch will use the Fallback addresses if the IP configuration isn‘t received from a DHCP
server in 2 minutes after initial boot. If Fallback address is used, DHCP Client will stop sending requests. If
the IP Configuration is received from a DHCP server, it will never fallback, even if the lease is lost.
(Revised 2010-7-30) Page 29 of 154
Administration – SNMP
The SNMP tab under the Administration category shows a list of IP Addresses that act as SNMP Traps.
The Read-Only, Read-Write, and Trap Community Names are also shown here.
By selecting the Modify button, you will be able to change any of the fields listed. This allows the user to
set an IP address for a Trap station or change the Community Names. If the SNMP Notification Trap is
enabled, systems that are listed as a Trap station will be sent the corresponding notification trap. To restore
a Trap to ―Value Not Configured‖, enter ‗0.0.0.0‘.
