APPLYING POWER (Side View)

Unscrew & Remove the DC Voltage Input Plug from the Power Input Header

Install the DC Power Cables into the Plug (observing polarity).

Plug the Voltage Input Plug back into the Power Input Header. This is the power disconnect device that must be removed before performing any kind of service or maintenance on the device.

Tightening torque for the terminal block power plug is 0.5 Nm/0.368 Pound Foot.

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 16-28AWG (0.08mm²-1.31mm²) 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 (Standard Voltage Models), similar to:

N-Tron’s P/N NTPS-24-1.3:

	Input AC 115/230V		Power 30W
	Output DC 24-28V	35 mm DIN-Rail Mountable
Output Current 1.3A @ 24V			Dimensions: 45X75X91 mm
	1.0A @ 28V

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.

SERIAL INTERFACE

The 700 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 700 Series Switch using a standard straight through serial 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 708 Series end.

The following table shows the pin-out and the connections for both types of cable:

PC Port	25-Pin	9-Pin		700 Series
	Female	Female		9-Pin Male
Signal Name	Pin #	Pin #	Pin #		Signal Name
TXD	2	3	3		RXD
RXD	3	2	2		TXD
GND	7	5	5		GND

Standard straight through serial cables are readily available from Radio Shack or a variety of computer stores.

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.

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.

The 700 Series switch also has the ability to allow overlapping VLANs. Overlapping VLANs give the user

(Revised 2013-06-21)

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 2013-06-21)

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 2013-06-21)

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.
