DIN-rail Mounting
When shipped, the DIN-rail mounting kit is fixed to the back panel of the EDS. Mount the EDS on the corrosion-free mounting rail that adheres to the EN 60715 standard.

Suggested Installation Method

• STEP 1
  Insert the upper lip of the DIN-rail kit into the mounting rail.

• STEP 2
  Press the device towards the mounting rail until it snaps into place. Alternatively, you can use a screwdriver to attach to the bottom of the DIN- rail kit and pull down.

Suggested Removal Method

• STEP 1
  Pull down the latch on the DIN-rail kit with a flat-head screwdriver.

• STEP 2
  Slightly pull the device forward and lift up to remove it from the mounting rail.

ATTENTION
When installing or removing the devices, please insert a flat-head screwdriver into the latch of the holding clamp and pull the latch downward rather than pushing it towards the DIN rail side, when removing the module from the rail.

If you want to change the position of the device on the DIN rail, please follow the steps shown in the images above. First, remove the device using a flat-head screwdriver and then re-install the device in the desired position. Please DO NOT directly move the device on the DIN rail, without uninstalling it first.

If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

Please use a flat-head screwdriver with a head size of between 4 and 6 mm for proper installation or removal.

NOTE

1. The installation and the safety of any system incorporating the equipment is the responsibility of the assembler of the system.
2. This is an OPEN TYPE module and should be installed in a safety enclosure with mechanical rigidity and an appropriate IP rating.

Wall Mounting (optional)
For some applications, you will find it convenient to mount EDS on the wall, as illustrated below.

There are two options for installation: The first option is to hook the EDS DIN-rail latch on the opening of the wall mount kit (see picture above) and then mount the wall-mount kit on the wall with screws.
(The other option is to perform these two steps in the other order.) 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.

NOTE 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.

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.

Once the screws are fixed in the wall, insert the two screw heads through the large parts of the keyhole-shaped apertures, and then slide EDS downwards, as indicated. Tighten the two screws for added stability.

WARNING
External metal parts are hot. Take necessary precautions if it is necessary to touch.

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

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 the Moxa EtherDevice Switch
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI).

Grounding the EDS-2008-EL Series
Run the ground connection from the ground screw to the grounding surface prior to connecting devices.
A 4 mm2 conductor must be used when a connection to the external grounding screw is utilized.

Grounding the EDS-2008-ELP Series
Run the ground connection from the top contact of the 3-contact terminal block 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.

NOTE When using shielded cables to connect two Ethernet devices, a ground loop may occur if the shielding on the cables generates an additional grounding connection path. This can cause ground current to flow through to the Ethernet ports and damage the devices. Therefore, STP cables must only be connected to the ground at one end.

Wiring the Power Input
The top two contacts and the bottom two contacts of the 2 or 3 contact terminal block connector on the EDS’s top panel are used for the EDS’s two DC inputs. Top and front views of one of the terminal block connectors are shown here.

• STEP 1
  Insert the negative/positive DC wires into the V-/V+ terminals.

• STEP 2
  To keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp screws on the front of the terminal block connector.

• STEP 3
  Insert the plastic terminal block connector prongs into the terminal block receptor, which is located on the EDS’s top panel.

NOTE The power source comes from secondary circuits. These circuits are separated from mains circuits by a transformer in which the primary windings are separated from the secondary windings by reinforced installation, double installation, or a screen connected to the protective conductor terminal.

ATTENTION
Before connecting the EDS to the DC power inputs, make sure the DC power source voltage is stable.

ATTENTION
One individual conductor in a clamping point with 28-14 AWG wire size, and a torque value of 1.7 lb-in should be used.

ATTENTION
The cable that is connected to the field wiring terminals must be capable of withstanding at least 105°C.

Communication Connections
The EDS-2008-EL/ELP models have 10/100BaseT(X) Ethernet ports and 100BaseFX Ethernet ports.

10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the EDS’s front panel are used to connect to Ethernet-enabled devices.
Below we show pinouts for both MDI (NIC-type) ports and MDI-X (HUB/Switch- type) ports, and show cable wiring diagrams for straight-through and cross- over Ethernet cables.

10/100Base T(x) RJ45 Pinouts

MDI Port Pinouts MDI- X Port Pinouts

RJ45 (8-pin) to RJ45 (8-pin) Straight-through Cable Wiring

RJ45 (8-pin) to RJ45 (8-pin) Cross-over Cable Wiring

100BaseFX Ethernet Port Connection
The concept behind the SC/ST port and cable is quite straightforward. Suppose you are connecting devices I and II. As opposed 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 are making 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 by the following illustration, or A1-to-A2 and B1-to-B2).

ATTENTION
This is a Class 1 Laser/LED product. To prevent damage to your eyes, do not stare directly into the laser beam.

DIP Switch Settings

NOTE The switch will only check the DIP switch functions when the device is powered on. To enable or disable the DIP switch functions, you must restart the switch.

priorities in four WRR queues.
QoS priority mapping matrix in each queue
QoS 3bit priority| 7, 6| 5, 4| 3, 2| 1, 0
Queues| 3| 2| 1| 0
WRR| 8| 4| 2| 1
Note: Enabling the QoS DIP switch will also enable Multicast Filtering which will block LLDP & PROFINET PTCP-Delay traffic by filtering frames with a destination MAC address within the range of 01-80-C2-00-00- 02 to 01-80-C2-00-00-0F.
OFF| Disable the Quality of Service.
Broadcast Storm Protection (BSP)| ON| Enables broadcast storm protection (at a maximum of 2048 broadcast packets per second) for each Ethernet port. The switch will discard any following incoming packets if the limit is exceeded.
OFF| Disables the broadcast storm protection.

LED Indicators
The front panel of the Moxa EtherDevice Switch contains several LED indicators. The function of each LED is described in the table below.

10M/ 100M

| Green| On| When the port is active and links on 100

Mbps.

Blinking| When the port’s data is being transmitted

at 100 Mbps.

Off| When the port is inactive or link down.
Amber| On| When the port is active and links on 10 Mbps.
Blinking| When the port’s data is being transmitted at 10 Mbps.
Off| When the port is inactive or link down.

Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the EDS’s
10/100BaseT(X) ports to any kind of Ethernet device, without paying 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 EDS to Ethernet devices.

Dual Speed Functionality and Switching
The EDS’s 10/100 Mbps RJ45 switch port auto negotiates with the connected device for the fastest data transmission rate supported by both devices. The EDS is a plug-and-play device, so software configuration is not required at installation or during maintenance.
The half/full duplex mode for the RJ45 switched 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 a 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. The EDS 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
The Moxa EDS has an address table that can hold up to 8,000 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, EDS 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
The EDS’s RJ45 Ethernet ports independently support auto-negotiation for transmission speeds of 10 Mbps or 100 Mbps, with operation according to the IEEE 802.3 standard. This means that some nodes could be operating at 10 Mbps, while at the same time, other nodes are operating at 100 Mbps.

When an RJ45 cable is connected, auto-negotiation takes place, and then each time a LINK is enabled. The EDS advertises its capability for using 10 Mbps or 100 Mbps, transmission speeds, with the device at the other end of the cable expected to advertise similarly. Depending on what type of device is connected, this will result in agreement to operate at a speed of 10 Mbps or 100 Mbps.

If an EDS’s 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 802.3 standard.
