The 9000 Series is a modular based Gigabit Ethernet Switch with up to 4 slots for ports and one slot for the CPU module. Please follow the steps below for adding, removing, or swapping modules in the 9000 series switch. Technicians performing the following steps should wear proper anti-static equipment to protect the circuit boards. WARNING: The 9000 series switch is
NOT hot swappable. Removing or adding modules while the power is still on can damage the equipment.
Adding or Replacing a Module:
1. Remove power from the switch.
2. Unscrew the two thumb screws for the filler panel or module that you are replacing.
3. Using both hands pull on both thumb screws to slide the filler panel or module you are replacing off the 9000BP.
4. Align the new module such that it slides on the rails and firmly push it into the unit.
5. Screw both thumb screws down till they are finger tight.
6. Reapply the power and configure the slots on the 9000 either through the web management interface or the serial
management interface.
NOTE: Modules should be installed in slot order (from left to right). So in a 2 slot configuration Slots A and B are populated.
Empty slots must be covered with a 9000-FP to meet emission standards.
Replacing a CPU Module:
1. Remove power from the switch.
2. Unscrew the two thumb screws for the CPU module that you are replacing.
3. Using both hands pull on both thumb screws to slide the CPU module out of the 9000BP.
4. Align the new CPU Module such that it slides on the rails and firmly push it into the unit.
5. Screw both thumb screws down till they are finger tight.
6. Reapply the power to the switch.
NOTE: All configuration settings are saved to the NVRAM which is stored locally on the CPU Module. If you replace the CPU
Module all settings will move with the CPU Module. You can save and download a custom configuration to a TFTP or an FTP server. The switch’s MAC Address and IP Address will also move with the CPU Module.

DIN-Rail Mounting
Install the unit on a standard 35mm Din-Rail. Recess the 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 a 45° upward angle. Lower the bottom of the unit until it snaps into place.
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 DIN­Rail. However, DIN-Rail mounting may not be suitable for all applications. Our Rack Mount Assembly (P/N: 900-RM) may be used to mount the 9000 Series to standard 19" racks as an option.
5/17/2007 page 11 of 138
Panel Mount Mounting
Install the unit directly on a wall or sturdy panel such as a bulkhead. Recess the unit to allow at least 5” of horizontal clearance for fiber cable bend radius.
To bulkhead mount the unit, place top edge of the bracket on the back of the unit against two screws at a 45° upward angle. Lower the bottom of the unit until it is flush with the wall, and secure the bottom of the unit with two more screws.
To remove the unit from a wall, remove the bottom two screws that secure it to the wall and slide the unit up until the top two screws will fit through the larger holes on the unit. The switch should then freely come away from the wall.

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 Din­Rail 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.
The use of shielded cables between devices is not required for most N-Tron devices (please consult the user manuals for specific details). 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.

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 other port to another Switch or Repeater, use a standard Category 5 straight through or crossover cable.
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.
SERIAL INTERFACE
The 9000 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:
5/17/2007 page 16 of 138
Serial Cable Connect the serial COM port of your PC and the 9000 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 9000 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 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 one 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.
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 filed) can be enabled or disabled by the user.
5/17/2007 page 18 of 138
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 9000 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 9000 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.
5/17/2007 page 19 of 138
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 9000 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 9000 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.

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. Once the administrator clicks on the Update button, the changes will take effect instantly.
Note: If there are multiple ports on different VLANs, the 9000 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. So 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.

RSTP – RSTP Configuration
The RSTP 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 button in the middle of the page.
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, the Forward Delay, the Max Age, the priority, and the Status of RSTP on that VLAN. 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.
NOTES:
1. Trunking must be disabled in order to use RSTP.
2. N-Ring Manager cannot have RSTP enabled.
3. RSTP & N-Ring are different modes and cannot have redundant links along those lines.
See the examples on the following sheet.
5/17/2007 page 46 of 138
RSTP – RSTP Configuration, Continued…
It is valid to have RSTP rings linked to non-N-Ring ports of active N-Ring Members, as above.
As marked above, it is not valid to expect RSTP to block redundant N-Ring links nor for N-Ring to block redundant RSTP links.
5/17/2007 page 47 of 138
RSTP – 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. In the below example, B1 is a redundant port with port A2, therefore A2 is forwarding and B1 is discarding.
5/17/2007 page 48 of 138

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. The factory default is that the Router Multicast Data Filter is disabled for all ports, so any router ports do get DATA frames with KNOWN multicast destination addresses. If rfilter is enabled router ports do NOT get DATA frames with KNOWN multicast destination addresses unless a join to a specific multicast address has been received on that port. ( Joins over-ride rfilter.) Rfilter can be set for individual ports: any, all, or none. For each port rfilter will have an impact only if that port is manually or dynamically chosen as a router port.

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 AutoMember mode and the N-Ring agingtime is 20 seconds.
Following the Modify button on the previous page, the administrator will see a list of configurable fields for the N-Ring configuration, as below.
The N-Ring Agingtime has a default of 20 seconds and is separate from the Bridging Aging Time. N-Ring Aging time is used for the whole switch if the switch is an N-Ring Manager or becomes an active N-Ring Member, and in either case N-Ring status includes for example:
“Switch is currently using N-Ring Aging Time = 20 Seconds”
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.

NView – Configuration
The Configuration tab under the NView category will display two basic variables for NView, 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 NView reports information. Increasing the interval will slow the update rate. Decreasing the interval will allow NView to report more frequently. Additionally, you may Disable or Enable NView altogether.
5/17/2007 page 60 of 138
NView – Ports
The Ports tab under the NView category will display a list of all the configured ports on the 9000 unit along with the ports transmitting multicast packets and MIB stats respectively.
5/17/2007 page 61 of 138

Following the Modify button on the previous 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.
5/17/2007 page 62 of 138
EventLog – Log Statistics
The Log Statistics tab under the EventLog category will show a list of how many times a type of event took place. On the bottom of the page it should also list the maximum log size which can be modified. There are 5 types of events that the 9000 will categorize messages in. If the log level is set to 1, the 9000 will log all 5 types of events. If the log level is set to 5 it will only record the Critical types (the 5th level).
Following the Modify button on the previous example, the administrator can modify these two variables to adjust for how large he or she wants the log file to be and the log level.
5/17/2007 page 63 of 138
EventLog – Show Events
The Show Events tab under the EventLog category will show a list of events that have occurred in the order in which they occurred. There is a time stamp for each event and they are categorized by the severity of the event.

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 9000 Series switch. This gives administrators the ability to backup their configurations to a server offsite in case they need to reload their custom configurations at a later time. Administrators are also given the ability to flash the switch in the field allowing them to update the firmware in the field without losing their current configurations and without having to send the unit back in to N-Tron for updates in the future. It is important not to cycle power on the switch or interrupt the data connection between the TFTP server and the switch while you are flashing or uploading or downloading a config file. The switch will not stop working if this does occur, but the administrator will have to retransfer the file.

BPCL – Broadcast Packet Count Limit Configuration
The BPCL link will display all the ports that are installed in the 9000 Series unit and will list the BPCL Percentage for each port. A modify button is provided to change these fields.
Following the Modify button on the previous example, the administrator can modify the BPCL Percentage for each port.
5/17/2007 page 68 of 138
User Mgmt – 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 previous 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 stating that the user was successfully added.
NOTE: There is a maximum number of 5 users per switch. User permissions have the right to view
switch configurations and to view current port settings, but cannot make any changes to these settings. Admin permissions have the right to change and view any switch configuration and to change and view any current port settings.

Logical View
The 9000 Web Management offers a logical view of the switch. Here a user or administrator can see a graphical depiction of the 9000 switch with the installed modules that have been configured in it. Ports that are linked will turn green, while ports that are not linked will show up as black. The example below shows only port 4 on the 9006TX module is linked. The other ports are currently in the down state (not being used).
5/17/2007 page 71 of 138
Config – Save and Restore
The Config section of the web management gives an administrator the ability to save a running config into the NVRAM. This step is needed in order for the switch to remember any changes after a power cycle. The Reset factory default button will reload N-Tron’s factory default configuration settings. Doing so will re-configure the 9000 Series switch to factory defaults.
In many cases it is desirable to restore factory defaults except retaining IP, Slot Configuration, Subnet Mask, and Gateway Address. A choice is provided to this end.
