Overview
The ToughNet TN-G4500 Series of M12 managed Ethernet switches are
designed for railway applications, including rolling stock and wayside
installations. The switches use M12 and other circular connectors to
ensure tight, robust connections, and guarantee reliable operation in
industrial environments where vibration and shock are commonplace.
These PoE switches are classified as power source equipment (PSE);
they provide up to 30 watts of power per port, and can be used to
power IEEE 802.3at/af compliant powered devices (PDs), such as IP
cameras, wireless access points, and IP phones.
The TN-G4500 Series has push-pull M12 connectors that are tailor-
made for push-pull cables in order to facilitate quick installation, and
also allow M12 rotary cables to be utilized. The 24 to 110 VDC wide
power input range and isolated dual power inputs not only allow the
same type of power source at different sites around the globe, but also
increase the reliability of communications systems. Furthermore, the -
40 to 70°C operating temperature capability make the switches suitable
for deployment in harsh environments. The TN-G4500 Series of
Ethernet switches are compliant with the essential sections of EN
50155, covering operating temperature, power input voltage, surge,
ESD, and vibration, as well as conformal coating and power insulation,
which makes the switches suitable for a variety of industrial
applications.

Mounting Dimensions (unit = mm)
Panel/Wall Mounting
STEP 1: Mounting the TN-G4500 to a wall requires 4 screws. Use the
ToughNet switch as a guide to mark the correct positions of the 4
screws.
STEP 2:
Use the 4 screws in the
panel mounting kit. If you would
like to use your own screws, make
sure the screw head
is between
6.0 mm and 7.0 mm
in diameter
and the shaft
is less than 4.0 mm
in
diameter, as shown at the right.
Do not screw the screws in all the way—leave a space of about 2 mm to
allow room for sliding the ToughNet switch between the wall and the
screws.

- 6 -
NOTE
Before tightening the screws into the wall, make sure the screw
head and shaft size are suitable by inser
ting the screw through
one of the keyhole-shaped apertures of the ToughNet switch.
STEP 3: Once the screws are fixed in the wall, hang the ToughNet
switch on the 4 screws through the large opening of the keyhole-
shaped apertures, and then slide the switch downwards. Tighten the
four screws for added stability.
NOTE
To provide greater protection from vibration and shock, use
screws with shaft diameter between 6.0 mm and 7.0 mm, and
fix the ToughNet switch onto the wall directly through the large
opening of the keyhole-shaped apertures.
Wiring Requirements
WARNING
Turn the power off before disconnecting modules or wires. The
correct power supply voltage is listed on the product label.
Check
the voltage of your power source to make sure you are
using the
correct voltage. Do NOT use a voltage greater than
what is
specified on the product label.
These devices must be supplied by a SELV source as defined in
the Low Voltage Directive 2006/95/EC and 2004/108/EC.
ATTENTION
Safety
First!
Be sure to disconnect the power cord before installing and/or
wiring your Moxa switch.
This device has UL 62368-1 approval.
Use copper conductors only,
70°C, and tighten to 4.5 pound-
inches. For use in pollution degree 2 environments.
ATTENTION
Safety First!
Observe all electrical codes dictating the
maximum current
allowable for each wire size. If the current
goes above the
maximum ratings, the wiring could overheat,
causing serious
damage to your equipment.

Please read and follow these guidelines:
•Use separate paths to route wiring for power and devices. If power
wiring and device wiring paths must cross, make sure the wires are
perpendicular at the intersection point.
NOTE: Do not run signal or communications wiring and power
wiring through the same wire conduit. To avoid interference, wires
with different signal characteristics should be routed separately.
•You can use the type of signal transmitted through a wire to
determine which wires should be kept separate. The rule of thumb
is that wiring that shares similar electrical characteristics can be
bundled together.
•Keep input wiring and output wiring separated.
•It is strongly advised that you label wiring for all devices in the
system when necessary.
Grounding the ToughNet Switch
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from
the grounding screw to the grounding surface prior to connecting
devices.
ATTENTION
To ground this product to earth,
use a green and yellow AWG
16 or higher grounding cable.
ATTENTION
This product is intended to be mounted to a
well-grounded
mounting surface such as a metal panel.
Connecting the Power Supplies
The ToughNet TN-G4500 Series switches support dual power inputs—
power input 1 and power input 2. The M12 K-coded 5-pin male
connector on the TN-G4500 Series switches' front panel is used for the
dual power inputs.

the TN-G4500 switch.
STEP 2: Screw the nut on your power cord connector into the power
input connector on the switch to ensure a tight connection.
ATTENTION
Before connecting the
TN-G4500 Series to the power input,
make sure the power source voltage is stable.
ATTENTION
Do not power on
the TN-G4500 Series before connecting the
M12 power connector.
Connecting the Serial Port
The TN-G4500 Series has a M12 B-coded 5-pin female connector. Users
can use an adapter to connect a management PC and control the device
using commands through the CLI (Command-Line Interface).

Ethernet Port Connection
The TN-G4500 Series has 12 10/100/1000BaseT(X) Ethernet ports
(M12 X-coded 8-pin female connector) and 4 10G BaseT(X) Ethernet
ports. Most users configure these ports for Auto MDI/MDI-X mode, in
which case the port’s pinouts are adjusted automatically depending on
the type of Ethernet cable used (straight-through or cross-over), and
the type of device (NIC-type or HUB/Switch-type) connected to the
port.
In what follows, we give pinouts for both MDI (NIC-type) ports and
MDI-X (HUB/Switch-type) ports. We also give cable wiring diagrams for
straight-through and cross-over Ethernet cables.
