STEP 2:
Mounting MOXA EtherDevice Switch on the wall requires 4 screws. Use the
Switch, with wall mount plates attached, as a guide to mark the correct
locations of the 4 screws. The heads of the screws should be less than 6.0 mm
in diameter, and the shafts should be less than 3.5 mm in diameter, as shown
in the figure at the right.
6.0 mm
Before tightening screws into the wall, make sure the screw head
and shank size are suitable by inserting the screw into one of the
keyhole-shaped apertures of the Wall Mounting Plates.
NOTE
3.5 mm
Do not screw the screws in all the way—leave about 2 mm to allow room for
sliding the wall mount panel between the wall and the screws.
STEP 3: Once the screws are fixed in the wall, insert the four screw heads through the large parts
of the keyhole-shaped apertures, and then slide MOXA EtherDevice Switch downwards,
as indicated below. Tighten the four screws for added stability.

Wiring Requirements
WARNING
Do not disconnect modules or wires unless the power supply has been switched off or the area is known
to be non-hazardous.
The devices may only be connected to the supply voltage shown on the type plate.
The devices are designed for operation with a safety extra-low voltage. Thus, they may only be
connected to the supply voltage connections and to the signal contact with the safety extra-low voltages
(SELV) in compliance with IEC950/ EN60950/ VDE0805.
WARNING
WARNING
Substitution of components may impair suitability for Class
I, Division 2 and Zone 2.
These devices must be supplied by a SELV source as defined in the Low Voltage Directive
73/23/EEC and 93/68/EEC.
This equipment has been evaluated as EEx nC IIC T4 equipment under DEMKO Certificate No.
03 ATEX 0324537U. Each module is marked
II 3G and is suitable for use in Zone 2
Explosive Atmospheres. The device must be installed in a minimum IP 54 enclosure as defined in
IEC 60529 and EN 60529.
ATTENTION
This unit is a built-in type. When the unit is installed in another piece of equipment, the equipment
enclosing the unit must comply with fire enclosure regulation IEC 60950/EN60950 (or similar
regulation).
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your MOXA EtherDevice
Switch.
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.
You should also pay attention to the following items:
!
!
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 in 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 to all devices in the system when necessary.

Grounding MOXA EtherDevice Switch
Grounding and wire routing help limit the effects of noise due to electromagnetic interference
(EMI). Run the ground connection from the ground screw to the grounding surface prior to
connecting devices.
This product is intended to be mounted to a well-grounded mounting surface, such as a metal
panel.
ATTENTION
Wiring the Alarm Contact
The Alarm Contact consists of the two middle contacts of the terminal block on EDS’s top panel.
You may refer to the next section for detailed instructions on how to connect the wires to the
terminal block connector, and how to attach the terminal block connector to the terminal block
receptor.
In this section, we explain the meaning of the two contacts used to connect the Alarm Contact.

100BaseFX Ethernet Port Connection
The concept behind the SC port and cable is quite straightforward. Suppose you are connecting
devices I and II. Contrary to electrical signals, optical signals do not require a circuit in order to
transmit data. Consequently, one of the optical lines is used to transmit data from device I to
device II, and the other optical line is used transmit data from device II to device I, for full-duplex
transmission.
All you need to remember is to connect the Tx (transmit) port of device I to the Rx (receive) port
of device II, and the Rx (receive) port of device I to the Tx (transmit) port of device II. If you
make your own cable, we suggest labeling the two sides of the same line with the same letter
(A-to-A and B-to-B, as shown below, or A1-to-A2 and B1-to-B2).

ATTENTION
This is a Class 1 Laser/LED product. To avoid causing serious damage to your eyes, do not stare
directly into the Laser Beam.
Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power sources. If one power
source fails, the other live source acts as a backup, and automatically supplies all of MOXA
EtherDevice Switch’s power needs.
Alarm Contact
MOXA EtherDevice Switch has one Alarm Contact located on the top panel. For detailed
instructions on how to connect the Alarm Contact power wires to the two middle contacts of the
6-contact terminal block connector, see the Wiring the Alarm Contact section above. A typical
scenario would be to connect the Fault circuit to a warning light located in the control room. The
light can be set up to switch on when a fault is detected.
The Alarm Contact has two terminals that form a Fault circuit for connecting to an alarm system.
The two wires attached to the Fault contacts form an open circuit when (1) EDS has lost power
from one of the DC power inputs, or (2) one of the ports for which the corresponding PORT
ALARM DIP Switch is set to ON is not properly connected.
If neither of these two conditions occurs, the Fault circuit will be closed.

Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect MOXA EtherDevice Switch’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 EDS to Ethernet devices.
Fiber Ports
MOXA EtherDevice Switch’s fiber switched ports operate at a fixed 100 Mbps speed and
full-duplex mode to provide the best performance. The fiber ports are factory-built as either a
multi-mode or single-mode SC connector. Consequently, you should use fiber cables that have SC
connectors at both ends. When plugging the connector into the port, make sure the slider guide is
positioned to the right side so that it fits snuggly into the port.
slider guide
slider ridges
slider
The 100 Mbps fiber ports are switched ports, and perform as a domain, providing a high
bandwidth backbone connection that supports long fiber cable distances (up to 2 km for
multi-mode, and 15 km for single-mode) for installation versatility.
Dual Speed Functionality and Switching
MOXA EtherDevice Switch’s 10/100 Mbps switched RJ45 port auto negotiates with the connected
device for the fastest data transmission rate supported by both devices. All models of MOXA
EtherDevice Switch are plug-and-play devices, so that software configuration is not required at
installation, or during maintenance. The half/full duplex mode for the switched RJ45 ports is user
dependent and changes (by auto-negotiation) to full or half duplex, depending on which
transmission speed is supported by the attached device.
Switching, Filtering, and Forwarding
Each time a packet arrives at one of the switched ports, a decision is made to either filter or
forward the packet. Packets with source and destination addresses belonging to the same port
segment will be filtered, constraining those packets to one port, and relieving the rest of the
network from the need to process them. A packet with destination address on another port segment
will be forwarded to the appropriate port, and will not be sent to the other ports where it is not
needed. Packets that are used in maintaining the operation of the network (such as the occasional
multi-cast packet) are forwarded to all ports.
MOXA EtherDevice Switch operates in the store-and-forward switching mode, which eliminates
bad packets and enables peak performance to be achieved when there is heavy traffic on the
network.
Switching and Address Learning
MOXA EtherDevice Switch has an address table that can hold up to 1K node addresses, which
makes it suitable for use with large networks. The address tables are self-learning, so that as nodes
are added or removed, or moved from one segment to another, MOXA EtherDevice Switch

automatically keeps up with new node locations. An address-aging algorithm causes the least-used
addresses to be deleted in favor of newer, more frequently used addresses. To reset the address
buffer, power down the unit and then power it back up.
Auto-Negotiation and Speed Sensing
All of MOXA EtherDevice Switch’s RJ45 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.
Auto-negotiation takes place when an RJ45 cable connection is made, and then each time a LINK
is enabled. MOXA EtherDevice Switch 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 similarly
advertise. 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 MOXA EtherDevice Switch RJ45 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.
