Moxa ToughNet Switch
Version 2.1, January 2021
*1802058000012*
Overview
The ToughNet TN-5816A/5818A switches are high performance M12
Layer 3 Ethernet switches that support Layer 3 routing functionality to
facilitate the deployment of applications across networks.
TN-5816A/5818A switches use M12 and other circular connectors to
ensure tight, robust connections and guarantee reliable operation against
environmental disturbances, such as vibration and shock.
TN-5816A/5818A switches support isolated power in the 24 to 110 VDC
power input range, allowing the same model to be used at different sites
around the globe. TN-5816A/5818A switches provide up to 16 Fast
Ethernet M12 ports with 2 bypass relay ports, and 2 Ethernet interface
Gigabit ports with bypass relay functionality. Furthermore, with a -40 to
75°C operating temperature and IP54-rated waterproof enclosure, the
switches can be deployed in harsh environments. The TN-5816A/5818A
series Ethernet switches are compliant with mandatory sections of EN
50155, covering operating temperature, power input voltage, surge, ESD,
and vibration, as we ll as conformal coating and power insulation, making
the switches suitable for a variety of industria l applications.

Please Read and Follow These Guidelines:
ATTENTION
This product is intended to be mounted to a well
mounting surface such as a metal panel.
• 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 ru le of thum b 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.

Connecting the Power Supplies
The ToughNet TN-5816A/5818A series switches support two sets of
power supplies—power input 1 and power input 2. The M23 6-pin male
connector on the TN-5816A/5818A’s front panel is used for the dual
power inputs.

Connecting the Relay Outputs
Each TN-5816A/5818A switch has two sets of relay outputs—relay output
1 and relay output 2.The M12 A-coded 5-pin male connector on the
TN-5816A/5818A front panel is used for the two relay outputs. Use a
power cord with an M12 A-coded 5-pin female connector to connect the
relay contacts. You can purchase an M12 power cable from Moxa; the
model number is CBL-M12 (FF5P)/OPEN-100 IP67.

FAULT:
The two sets of relay contacts of the M12 A-coded 5-pin male connector
are used to detect user-configured events. The two wires attached to the
fault contacts form an open circuit when a user-configured event is
triggered. If a user-configured event does not occur, the fault circuit
remains closed.
Connecting the Data Lines
10/100BaseT(X) Ethernet Port Connection
All TN-5816A/5818A models have 16 10/100BaseT(X) Ethernet ports
(4-pin shielded M12 connector with D coding). The 10/100TX ports
located on the TN-5816A/5818A 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.

Bypass Relay Function
The TN-5816A/5818A is equipped with a bypass relay function. When the
switch is operating normally, these bypass ports work in the same way as
the other ports. That is, frame ingressions are processed and then
forwarded. If the switch stops working due to a power failure, the bypass
relay function will be triggered to ensure non-stop data communication.
The figure below illustrates the bypass relay function. For example, if
Switch B loses power, then the two Gigabit ports will be bypassed through
the relay circuit and the transmission line from Switch A to B and the
transmission line from Switch B to C will interconnect automatically,
ensuring that power continues to be supplied.
The bypass relay function helps the network recover from single-node
failures in a linear topolog y.
Switch A Switch B Switch C Switch D
Bypassing
Since the maximum segment length of category 5 twisted-pair cab le is
100 meters, cable length must be considered when designing a network
that utilizes this function. For example, the total length of the cables from
Switch A to B and from B to C must be no more than 100 meters. This way,
if the two adjacent nodes (switch B and C for example) encounter a power
failure, there will be no stoppage, provided that the total length of the
cables A-to-B, B-to-C, and C-to-D are no more than 100 meters.
The bypass relay function works best for networks with linear topologies.
ToughNet™ switches with bypass relay function are not recommended to
be used in networks that employ ring topologies because network loops
may occur when redundancy protocols such as RSTP or TurboRing™ are
applied.
