Functional Overview
The 105TX-POE and 105FX-POE Power over Ethernet Unmanaged Industrial Ethernet Switches are
designed to provide power over Ethernet for POE capable devices where running a power line is either not
possible or not cost effective. This feature allows an end user to power a POE camera, wireless access
point, or any other POE capable device without the need for running separate wires for power. This also
allows the ability for a centralized battery backup for all these devices.
The 105FX-POE utilizes the IEEE compliant SC or ST duplex connectors for fiber optic communication.
All 10/100Base-TX ports utilize the RJ45 shielded connectors.

DIN-Rail Mounting
Install the unit in a standard DIN rail. Recess the unit to allow at least 2” of horizontal clearance for CAT5e
cable bend radius.
To install the unit to 35mm industrial DIN rail,
place the top edge of the included mounting
bracket on the back of the unit against the DIN
rail at a 15° angle as shown. Rotate the bottom of
the unit to the back (away from you) until it
snaps into place.
To remove the unit from the 35mm industrial
DIN rail, place a flat head screwdriver into the
release clip found at the bottom of the unit, and
apply downward force on the clip until it
disengages from the bottom of the unit from the
DIN rail. Rotate the bottom of the unit towards
you and up at an approximate 15° 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 Rack
Mount Assembly (P/N: 900-RM)
may be used to mount the
105TX/FX-POE
enclosures
to
standard 19" racks as an option.

APPLYING POWER (Top View)
Unscrew & Remove the DC Voltage Input Plug from the top header.
Install the DC Power Cables into the Plug (observing polarity on unit).
Plug the Voltage Input Plug back into the top header.
Tightening torque for the terminal block power plug is 0.22 Nm/0.162 Pound Foot.
Turn the power on the wire.
Note: It is only safe to turn the power on the wires after the wires have been secured to the
switch.
WARNING: Inserting the input plug while the 48VDC is applied may cause arcing, and damage
the input connector permanently.
Note: Either V1 or V2 can be connected to power for minimal operation. For redundant power
operation, V1 and V2 plugs must be connected to separate DC Voltage sources. Use wire sizes of 10-20
gauge. The power cord should be limited to less than 10 meters in order to ensure optimum
performance.

N-TRON GROUNDING TECHNIQUES FOR 105TX-POE AND 105FX-POE
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.
Users may run a drain wire & lug from the screw provided on the back face of the
enclosure. In the event the provided grounding screw has been lost, care should
be taken to limit the penetration of the outer skin by less than 1/4". Failure to do
so may cause irreversible damage to the internal components of the switch.
Note: Ensure the power supply is grounded properly before applying power to the
grounded switch. This may be verified by using a voltmeter to determine that
there is no voltage difference between the power supply’s negative output terminal
and the chassis grounding point of the switch.
As an alternative grounding method, 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.
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 the 100BaseFX Fiber Optic port (105FX-POE), remove the dust cap(s) from the fiber optic connector and
connect the fiber optic cables. The TX port on the local unit should be connected to the RX port of the far end
device, and the RX port should be connected to the TX port of the far end device.
For 10Base-T ports, plug a Category 3 (or greater) twisted pair cable into the RJ45 connector. For
100Base-T ports, plug a Category 5 (or greater) 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 Cat5 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!
TROUBLESHOOTING
1. Make sure the (Power LED) is ON.
2. Make sure you are supplying sufficient current for the 105TX-POE or 105FX-POE and all powered
devices plugged into it. Note: The inrush current and steady state current is dependent on the
power requirements of the powered devices plugged into the POE switch.
3. Verify that the POE light is on solid if a valid POE PD is connected to the port.
4. Verify that Link LED’s are ON for both ports.
5. Verify cabling used between stations.
6. Verify that cabling is Category 3 or greater for 10Mbit Operation.
