DIN RAIL MOUNTING
Install the unit on a standard 35mm Din-Rail. Recess the 7014TX unit to allow at least 3” of horizontal clearance for fiber cable
bend radius. Recess the 7014FX2 unit to allow at least 5” of horizontal clearance for fiber cable bend radius.
To mount the unit to the 35mm din-rail, place top edge of the bracket
on the back of the unit against the din-rail at an upward angle. Lower
the bottom of the unit until it snaps into place.
Note: When mounting the switch in the vertical position, you must
orientate the power connector to the top as shown above for proper
ventilation.
To remove the unit from the 35mm din-rail, place a flat
head screwdriver into the release clip at the bottom of the
unit, and push down on the clip until it disengages from
the bottom of the unit from the din-rail. Lift the bottom of
the unit up at an approximate 45° upward angle to
completely remove the unit.
Most N-Tron™ products are designed to be
mounted on industry standard 35mm DIN-
Rail. However, DIN-Rail mounting may not
be suitable for all applications. Our Universal
Rack Mount Kit (P/N: URMK) may be used
to mount the 7014 Series to standard 19"
racks as an option.

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 LED‟s 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 pre-
manufactured 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: In absence of RSTP or Proprietary Ring control on the specific ports connected, 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. 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. 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 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.

SERIAL INTERFACE
The 7014 Series switches provide an EIA-232 interface accessed via a 9 pin female connector (labeled
„COM‟ on the unit). This is used to access the Command Line Interpreter (CLI). The pin-outs are shown
below:
Serial Cable
Connect the serial COM port of your PC and the 7014 Series Switch using a standard straight through cable.
You will require a cable with a 9-pin or 25-pin sub-D female connector for the PC end, and a 9-pin male
sub-D connector for the 7014 Series end.

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 (backoff) 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 that of the station.
Port Security
Port Security provides a mechanism to detect any intruder in the network. When security is enabled on the
port, the port stops learning new MAC addresses on that port and if it receives any packet with a source
MAC address that is not in the address table, the packet will be discarded.
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 or more 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 trunk can act as a single link between the switches.

(Revised 2011-07-21) page 19 of 152
Priority Tagging (QoS)
IEEE 802.1p priority tagging is supported for two classes of services along with bandwidth support per
priority level. Transparent mode is supported through configuration wherein if the field is set, the tag bits
are ignored. The User can configure up to 8 different priority levels per port. Also priority overriding
(overriding the tagged field) can be enabled or disabled by the user.
Virtual LAN
The switch provides support for setting up both tagged Virtual LANs and port based Virtual LANs. A port
may belong to any number of Virtual LANs. The VLAN membership of a station is determined by the
VLAN(s) that have been defined for the port to which the station is connected. If a station should move
from one port to another, it loses its current VLAN membership and inherits that of the new port it is
connected to.
A Default Virtual LAN 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‟ Bridge 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.
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 so he can 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.
The 7014 Series switch also has the ability to allow overlapping VLANs. Overlapping VLANs gives 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 our website‟s technical documents.
Rapid Spanning Tree Protocol
The rapid spanning tree protocol as specified in IEEE 802.1D-2004 is supported. One Spanning Tree per a
unit is supported. Besides a Spanning Tree per VLAN is also 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 7014 Series switch supports up to 5 SNMP Trap Stations to which SNMP Traps will be sent. The
switch supports three standard traps; Link Up, Link Down, and Cold Start. SNMP Traps will be sent to all
the stations configured on the switch if a port Link goes up or down, and when the switch first powers up.
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 console and if enabled, then 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 7014 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 7014 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 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.
