Overview: 308FX2/309FX/316TX/317FX Industrial Ethernet Switches
The 308FX2/309FX/316TX/317FX Industrial Ethernet Switches support high speed layer 2 switching
between ports. The copper ports in this line are Category 5 compliant 10/100-BaseTX connections for
high performance network design, and hub/repeater upgrades. These copper ports are capable of auto
negotiating 10/100 Mb and half/full duplex communications, or the user can configure these parameters.
The 308FX2 is an affordable 8 port switch that has 6 copper ports plus two additional multimode fiber
optic up-link ports. The two fiber links are capable of 2 Kilometers of 100 Mb communications without
the use of repeaters.The 308FXE2 is similar to the 308FX2, but is populated with singlemode extended
range fiber optics.
The 316TX is an affordable 16 port copper port switch.
The 309FX (317FX) is a 9 (17) port switch that has 8 (16) copper ports, plus an additional multimode
fiber optic up-link port in the 309FX and in the 317FX. These fiber links are capable of 2 Kilometers of
100 Mb communications without the use of repeaters.
The 309FXE (317FXE) is a 9 (17) port switch that is similar to the 309FX (317FX), but with extended
range. The FXE versions utilize a singlemode fiber transceiver that is capable of 15-80 Kilometers of
200 Mb communications.
All FX, FX2, FXE, and FXE2 models utilize the IEEE compliant SC or ST duplex connector for fiber
optic communications. The 10/100Base-TX ports utilize the RJ45 shielded connector.

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. Please note that the minimum crosssectional area of the grounding conductor must be at least 4mm2
and it must be suitable for use in temperature of 110°C.
Note: Ensure the power supply

is grounded properly before applying
This may be verified by using a
is no voltage difference between the
terminal and the chassis grounding
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.
(Revised 2013-06-21)
12
RJ45 Connector Crimp 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.
Warning: Creating a port to port connection on the same switch (i.e. loop) is an illegal operation and will create a
broadcast storm which will crash the network!
Note: For units which have the N-View Option (-N), you can validate that all ports are working correctly by
installing the N-View OPC Server software. The software is freely distributed on the ProductCD and our website
(http://www.n-tron.com/pdf/setup_nviewopc.zip). Once the software is installed, you should view the Ports
Counter page to remotely monitor each connected port. You may find it helpful to copy [Alt]+[Print Screen] 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.

Serial Cable
Connect the serial COM port of your PC and the 308FX2/309/316/317 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 308FX2/309/316/317 end.

Literally thousands of switches in one normal LAN can have N-View enabled without negative impact, but
for LANs that include extremely low bandwidth wireless links N-View can be disabled.

System Info
System info provides information on each port, as shown in the example below. Note that this is real time
status, and some parameters (such as Rate, Duplex, and Crossover) will oscillate if not linked and not forced.
To see forced settings, go to switch/ports/info.

Restoring defaults
Restoring factory defaults has these affects:
 All ports are enabled.
 All RJ45 ports are set for auto-sensing. All FX ports are set to 100 MHz and Full Duplex.
 All RJ45 ports are set to auto-MDIX (as opposed to enabling crossover only).
 N-ViewTM is enabled on –N units.
 On the 308FX2, both ring filters are enabled.
The MAC address, model number, and firmware version are protected settings. These settings are
unaffected by restoring factory defaults.

Ports
By default, the RJ45 ports are auto-sensing for speed, duplexing, and crossover or straight through wiring.
When you select ANY ‘forced’ option, the auto-sensing for that port is disabled for all three parameters and
the ‘remaining’ (unforced) options are set to 100 Mbits, Full Duplex, and straight through cabling. For
example, if you select speed10 for port 2, then port 2 will be: speed10, full duplex, and straight through
wiring. If you need ‘half duplex’ also on port 2, you will have to select it also as auto-sensing will be
disabled for port 2 after you forced speed10. The FX ports are always 100 Mb, and Full Duplex.
Warning:
In a LAN it is best to set ALL devices at autonegotiate, OR to set ALL devices to the
same mode (speed/duplex).
If one end of a link is set to forced speed/duplex, but the other end is not forced, problems can be created.
Why do folks not trust autonegotiation? Many learned (mostly in past or on older equipment) not to trust
autonegotiation. Why? Many implementations were out before the spec was finalized, so did not play well
together. (We have seen a case where the wiring was cat3 and the devices autonegotiated to 100/full, but the
wiring would not support it.)
On the 308FX2, 309, 316, or 317, one can autonegotiate, or one can force to any of 4 modes: 100 full, 100
half, 10 full, or 10 half.
If you force one unit into 10/full, and leave another in autonegotiate (the default), the unit in autonegotiation
does not go into 10 full. It goes into 10 half. It gets no autonegotiation response. It easily senses speed
passively, but has no way to sense duplex mode and so uses the "safest" duplex mode - half. This is in
accordance with the IEEE specification. Thus, you have one unit at 10 full and the other at 10 half (Revised 2013-06-21)
22
basically functional but not ideal. The unit at 10 full transmits without checking for busy and you get more
collisions. Also, the 10/full unit does not back off or retransmit based on the collision domain.
The same problem happens with one unit forced to 100/full and the other autonegotiating. The
autonegotiating unit goes into 100/half.

<enter> (no ports) to the prompt “Enter forced 10 Mb ports:”, then no ports in the switch will be forced to 10
Mb, regardless of prior history.
