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.
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.
RJ45 CONNECTOR CRIMP SPECIFICATIONS Please reference the illustration below for your Cat5 cable specifications: Revision 050908 Page 13 of 101
SERIAL INTERFACE The 708 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.
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: - Half Duplex - Full Duplex - Auto Negotiation 100Base Fiber Ports: - Full Duplex 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.
Virtual LAN The switch provides support for setting up tagged 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.
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.
TROUBLESHOOTING 1. Make sure the (Power LED) is ON. 2. Make sure you are supplying sufficient current for the version chosen. Note: The Inrush current will exceed the steady state current by ~ 2X. 3. Verify that Link LEDs are ON for connected ports. 4. Verify cabling used between stations. 5. Verify that cabling is Category 5E or greater for 100Mbit operation.

Bridging – Aging Time The Aging Time tab under the Bridging category will display the currently configured Aging Time. This page allows users to modify this variable to meet their needs. After selecting the Modify button, the user will be presented with a page that allows the number to be entered into and updated. The default aging time is 20 seconds. Note: If the switch is an active participant of an N-Ring, then the N-Ring Aging Time will be used instead of the Bridging Aging Time.
Bridging – Unicast Addresses The Unicast Addresses tab under the Bridging category will display a list of MAC addresses that are associated with each respective port number. This can be used to statically assign a MAC address access to a single port on the switch. Following the Add button on the page above, the administrator must enter a valid MAC address and associate it with a port number on the switch. Once the administrator hits the Add button, the changes will take effect instantly.
Bridging – Unicast Addresses, Continued… Once a static MAC address has been added, it will be displayed in a list on the main page under Unicast MACs tab. Following the Remove button on the example above, an administrator can select a static MAC address from the list using a pull-down menu.
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.
Bridging – Multicast Addresses Continued… After adding a Multicast Group Address, it will appear on the main list and will show the associated ports that go along with that address. Following the Remove button on the example above, the administrator will be presented with a list of Multicast Group Addresses that are configured on the switch. Using the pull-down menu, the administrator should select the desired address to be removed. Then click on the Remove button at the bottom of the page.
RSTP – Configuration The Configuration tab under the RSTP category will display the RSTP information for the first VLAN. Using the pull-down menu at the top of the page an administrator can choose which VLAN to configure RSTP on. Once the VLAN is selected, the administrator may configure the bridge by clicking on the ‘Configuration’ link in the middle of the page.
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.
RSTP – Configuration Continued… 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.
IGMP – Configuration The Configuration tab under the IGMP category will display the IGMP basic configuration settings. By default, IGMP is enabled. Following the Modify button, the administrator will see a list of configurable fields for the IGMP configuration. Once these fields are filled in to meet the needs of the administrator’s network, the changes may be updated by clicking the Update button at the bottom of the page.
IGMP – Configuration, Continued… The IGMP Status pull-down allows the user to enable or disable IGMP completely.
IGMP – Configuration, Continued… The Router Mode pull-down allows the user to choose router mode. ‘Auto’ allows for dynamically detected and manually set router ports. ‘Manual’ allows only for manually set router ports. ‘None’ allows no router ports.
IGMP – Show Group and Show Router The Show Groups tab under the IGMP category will display a list of IGMP groups based on the Group IP and the port number that it is associated with. The Show Routers tab under the IGMP category will display a list of Auto-detected Router IPs and the port numbers that they are associated with.
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.
IGMP – RFilter, Continued… Modifying rfilter port settings: Revision 050908 Page 49 of 101
N-View – Configuration The Configuration tab under the N-View category will display two basic variables for N-View, the status and the interval between packets. Following the Modify button on the above example, the administrator can modify the variable to change the frequency with which N-View reports information. Increasing the interval will slow the update rate. Decreasing the interval will allow N-View to report more frequently. Additionally, you may Disable or Enable N-View altogether.
N-View – Ports The Ports tab under the N-View category will display a list of all the configured ports on the 708 unit along with the ports transmitting multicast packets and MIB stats respectively. Following the Modify button on the above example, the administrator can modify these two variables to enable or disable multicast out of the port and if MIB stats are sent out for those ports.
N-Ring – Configuration The Configuration tab under the N-Ring category will display the N-Ring basic configuration settings. By 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.
5. 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 as available of ports TX1 and TX2, or TX7 and TX8 (FX1 and FX2 on 708FX2) as N-Ring ports.
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.
N-Ring – Advanced Configuration If switch is an N-Ring Member, the following data will be shown: N-Ring Mode Current N-Ring mode of switch. Keep-Alive Timeout: Keep-Alive timeout is used when switch is active in an N-Ring. The range is 5-1000000 seconds. If switch is an N-Ring Manager, the following advanced configuration data will be shown: N-Ring Mode Current N-Ring mode of switch. Self Health Packet Interval: The amount of time to wait in milliseconds before sending Self-Health packets.
The amount of time, in milliseconds, that must elapse before the ring is allowed to go back into the broken state. The default is 3000.
N-Ring – Status The Status tab under the N-Ring category will display the N-Ring status.
N-Ring – Status, Continued… Below is an example of N-Ring Status from an N-Ring Manager with a healthy N-Ring: Revision 050908 Page 58 of 101
N-Ring – Status, Continued… Below is an example of N-Ring Status from an N-Ring Manager with a faulted N-Ring. The red fields on the N-Ring Map show problems. Ports that are red indicate that the port is not linked. MAC addresses that are red indicate that there is no communication to that switch. The red “Ring Broken” line shows where the N-Ring is broken.
N-Ring – Status, Continued… In rare cases an N-Ring can have a “Partial Fault”. An example of this is to have a break in just one fiber in a duplex channel fiber pair.
Firmware/Config – TFTP The TFTP tab under the Firmware/Config category gives the administrator the ability to upload or download a config file for a 708 Series switch. This allows administrators to backup their configurations to a server offsite in case they need to reload their custom configurations at a later time.
Support – Web Site and E-mail If at any point in time you get confused or would like additional support directly from N-Tron, you may visit N-Tron’s web site, or e-mail N-Tron directly with the links provided for more information.
BPCL – Broadcast Packet Count Limit Configuration The BPCL link will display all the ports that are installed in the 708 Series unit and will list the BPCL Percentage for each port. BPCL defaults to 3%. A Modify button is provided to change these fields. Following the Modify button on the above example, the administrator can modify the BPCL Percentage for each and every port.
User Management – Adding Users The User Management link will display a list of all the users who have access to the management features of the switch and their access permissions. Following the Add button on the above example, the administrator can add another user and assign the user a username, a password, and the user’s permissions (user/administrator). A page should display after the administrator clicks the Add button indicating that the user was successfully added.
User Management – Removing Users In order to remove a user, simply click on the Remove button at the bottom of the page. Following the Remove button on the above example, the administrator can remove a user by entering in the user’s name and clicking the Remove button. A page should follow indicating that the user was successfully removed from the list. Note: There are a maximum number of 5 users per switch.
LogicalView The 708 Web Management offers a logical view of the switch. Here a user or administrator can see a graphical depiction of the 708 switch. Ports that are linked will appear in green, while ports that are not linked will appear in black. The example below shows ports 1, 2, and 8 linked. The other ports are currently in the down state (not being used).
Configuration – Save or Reset The Configuration section of web management gives an administrator the ability to save a running configuration into the NVRAM. This step is needed in order for the switch to remember any changes after a power cycle. The “Save” button will save all current changes to the configuration for use after the next power cycle. The “Reset” button will discard all unsaved changes, reset the switch and load the most recently saved configuration settings.
Help When the Help link is clicked on, you will see the Overview page that will have some basic definitions and more specific choices at the top of the screen. Although this page is not as detailed as the manual, it gives you a basic feel for different features the 708 offers.

VLAN Addition and Deletion Example The screen capture below is the factory default VLAN configuration.
When creating a new VLAN, a numeric ID is required, Name is entered. Note that N-Ring VLAN is a reserved name with a special meaning. Choices such as “Allow Management” and “Change PVID of Member Ports” are made at this time as well as the ports which are going to belong to the new VLAN. Additionally, the ports may be “Untagged on Egress”.
The result of add is a “New VLAN”. In this case, it does not overlap the “Default VLAN” ports.
The ports of ”New VLAN” may be added back to “Default VLAN” to create overlapping VLANs. Note: If there are multiple ports on different VLANs, the 708 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. 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.
Revision 050908 Page 91 of 101
And the “New VLAN” is removed. Note that the new configuration of the switch must be saved if the configuration must survive a power cycle.
VLAN Configuration Examples A VLAN is an administratively configured LAN segment that limits the traffic in multiple broadcast domains. Instead of physically reconnecting a device to a different LAN, network administrators can accomplish this task by configuring a VLAN compliant switch to create logical network segments. Tagged VLAN allows switch segmentation to span across multiple managed switches.
