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

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.
