RED Power is Applied with an active fault.
Applying Power The M12 A coded power connector is keyed, where the mating connection from the power supply can be made only when the male and female ends are lined up properly. When the power is first connected all LED’s will flash ON Momentarily. Verify the Power LED stays ON (GREEN). Note: Either V1 or V2 can be connected to power for minimal operation. For redundant power operation, V1 and V2 must be connected to separate DC Voltage sources.
N-TRON 708M12 Grounding Techniques Drain wire with lug connecting switch chassis to known grounding point. CONNECTING THE UNIT For 10Base-T ports, plug a Category 3 (or greater) twisted pair cable into the M12 connector. For 100Base-T ports, plug a Category 5 (or greater) twisted pair cable into the M12 connector. Connect the other end to the far end station. Verify that the LNK LED’s are ON once the connection has been completed.
SERIAL INTERFACE The 708M12 Switch provides an EIA-232 interface accessed via an A Coded female connector (labeled ‘COM’ on the unit). This is used to access the Command Line Interpreter (CLI). The pin-outs are shown below: SERIAL-DB9-M12 Serial Cable Connect the serial COM port of your PC and the 708M12 Switch using N-Tron’s SERIAL-DB9-M12 serial cable. You will require a cable with a 9-pin or 25-pin sub-D female connector for the PC end, and a 4-Pin A Coded M12 Male connector for the 708M12 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 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 – 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.

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 071108 Page 49 of 102
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.
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.

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.

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 071108 Page 92 of 102
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.
