Wall Mounting (OPTIONAL)  
For some applications, you will find it convenient to mount MOXA EtherDevice Switch on the  
wall, as illustrated below.  
STEP 1:  
Remove the aluminum DIN-Rail attachment plate from MOXA EtherDevice Switch’s rear panel,  
and then attach the wall mount plates, as shown in the diagram below.

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.  
FAULT  
FAULT: The two middle contacts of the 6-contact  
terminal block connector are used to detect both  
power faults and port faults. The two wires  
attached to the Fault contacts form an open circuit  
when:  
Top View  
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.

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  
13 —  
 
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.
