Overview
The ToughNet TN-5308 series M12 unmanaged Ethernet switches are
designed for industrial applications in harsh environments. The TN series
switches use M12 connectors to ensure tight, robust connections, and
guarantee reliable operation against environmental disturbances, such as
vibration and shock. The TN-5308 series Ethernet switches provide 8 Fast
Ethernet M12 ports, support IEEE 802.3/802.3u/802/3x with 10/100M,
full/half-duplex, MDI/MDI-X auto-sensing, and provide an economical
solution for your industrial Ethernet network. Models with an extended
operating temperature range of -40 to 75°C are also available. The
TN-5308 series Ethernet switches comply with those EN 50155
requirements that make products more suitable for rolling stock
applications, including operating temperature, power input voltage, surge,
ESD, and vibration, making the switches suitable for a variety of industrial
applications.

Panel/Wall Mounting
Mounting the TN-5308-LV/MV on the wall requires 3 screws. Please use
the 3 screws packed in the panel mounting kit.
STEP 1: Prepare the 3 screw holes on the wall according to the positions
of the 3 screw holes on the switch shown on the mounting dimension
diagram.
STEP 2: Use one screw to go through the top-middle screw hole on the
switch and screw it into the wall.
STEP 3: Screw in the remaining 2 screws through the bottom-left and
bottom-right holes on the switch to the wall.
NOTE
The screw lengths of TN
-5308-LV and TN-5308-
MV are different.
TN
-5308-LV uses M3 x 30 mm screws. TN-5308-MV uses M3 x
40
mm screws. Please use the screws packed in the panel mounting
kit.
DIN-Rail Mounting (optional)
With the optional DIN-Rail mounting kit DK-TN-5308 (must be purchased
separately), you can mount the TN-5308-LV/MV on a 35 mm DIN-Rail.
STEP 1:
Fix the DIN
-Rail attachment plate onto
the
rear panel of the switch as shown in the
figure at the right.
STEP 2:
Position the TN
-5308-LV/MV on
the DIN
-Rail, tilting to hook
clamps over the top edge of the
rail.
STEP 3:
Swing the switch down fully onto the
DIN
-Rail until both clamps
completely latch.
To remove the Moxa ToughNet Switch from the DIN-Rail, simply reverse
Steps 2 and 3 above.

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 def
ined 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 UL508 approval. Use copper
conductors only,
60/75°C
, and tighten to 4.5 pound-inches. For use in pollution
degree 2 environments.
ATTENTION
Safety First!
Calculate the maximum possible current in each power wire and
common wire. 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 TN-5308
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
This product is intended to be mounted to a
well-grounded
mounting surface such as a metal panel.
Connecting the Power Supply
The M12 A coded 5 pin and M23 6 pin male connector on the
TN-5308-LV/MV front panel is used for the DC power input. You have to
prepare a power cord with M12/M23 A-coded 5-pin female connector to
connect the switch to the DC power input.
Pinouts for the power input port on the TN-5308-LV
Pinouts for the power input port on the TN-5308-MV
STEP 1: Plug your power cord connector to the power input port of the
TN-5308 switch.
STEP 2: Screw the nut on your power cord connector to the power input
connector on the switch to ensure a tight connection.
ATTENTION
Before
connecting the TN-
5308 to the DC power input, make sure
the DC power source voltage is stable.

Connecting the Data Lines
10/100BaseT(X) Ethernet Port Connection
All TN-5308 models have 8 10/100BaseT(X) Ethernet ports (4-pin
shielded M12 connectors with D coding). The 10/100TX ports located on
the TN-5308’s front panel are used to connect to Ethernet-enabled
devices. 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.

Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect TN-5308’s
10/100BaseTX ports to any kind of Ethernet device, without needing to
pay attention to the type of Ethernet cable being used for the connection.
This means that you can use either a straight-through cable or cross-over
cable to connect the TN-5308 to Ethernet devices.
LED Indicators
Several LED indicators are located on the TN-5308’s front panel. The
function of each LED is described in the table below.

Auto-Negotiation and Speed Sensing
All of the TN-5308’s Ethernet ports independently support
auto-negotiation for speeds in the 10BaseT and 100BaseTX modes, with
operation according to the IEEE 802.3u standard. This means that some
nodes could be operating at 10 Mbps, while at the same time, other nodes
are operating at 100 Mbps.

- 11 -
Auto-negotiation takes place when an M12 cable connection is made, and
then each time a LINK is enabled. The TN-5308 advertises its capability
for using either 10 Mbps or 100 Mbps transmission speeds, with the
device at the other end of the cable expected to advertise in the same way.
Depending on what type of device is connected, this will result in
agreement to operate at a speed of either 10 Mbps or 100 Mbps.
If a TN-5308’s Ethernet port is connected to a non-negotiating device, it
will default to 10 Mbps speed and half-duplex mode, as required by the
IEEE 802.3u standard.
