SERVICING
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.
7. In order to verify the settings have been configured and saved correctly, you may want to view the Logical View page in
the found in the web browser interface. The dynamic illustration displayed on the Logical View page must match the
physical switch configuration respectively in order for the switch to function correctly. If not, please repeat the steps
listed above.
8. Validation of the configuration and each physical cable segment may be obtained by using
9. N-ViewOPC Server software. The software is freely distributed on the ProductCD and our web site
(http://www.ntron.com/pdf/setup_nviewopc.zip). Once N-ViewOPC is installed, you should view the Ports Counter
page view each connected port. You may find it helpful to copy [Alt]+[PrintScreen] the Port Counter information for
each port and paste [Control]+[V] into a Windows document for further review. Please consult your N-View OPC
Server manual for additional information.
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 DIN-
Rail. However, DIN-Rail mounting may not
be suitable for all applications. Our Universal
Rack Mount Kit (P/N: URMK) may be used
to mount the 9000 Series to standard 19"
racks as an option.

(Revised 2011-07-20) page 13 of 145
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 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. 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 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.

CAT5 CABLE SPECIFICATIONS
Please reference the illustration below for your Cat5 cable specifications:

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.
Warning: In absence of RSTP or Proprietary Ring control on the specific ports connected, creating a port
to port connection on the same switch (i.e. loop) is an illegal operation and will created a broadcast storm
which will crash the network!
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:

(Revised 2011-07-20) page 19 of 145
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.
