Mounting Dimensions

Unit = mm (inch)
DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should already be fixed to the back panel of EDS-316 when you take it out of the box. If you need to reattach the DIN-Rail attachment plate, make sure the stiff metal spring is situated towards the top, as shown in the figures below.

• STEP 1: Insert the top of the DIN-Rail into the slot just below the stiff metal spring.
• STEP 2: The DIN-Rail attachment unit will snap into place as shown below.

To remove Moxa EtherDevice Switch from the DIN-Rail, simply reverse Steps 1 and 2 above.

Wall Mounting (optional)
For some applications, you will find it convenient to mount EDS-316 on the wall, as illustrated in the figure.

• STEP 1: Remove the aluminum DIN-Rail attachment plate from EDS-316’s rear panel, and then attach the wall mount plates, as shown in the figure.
• STEP 2: Mounting EDS-316 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.

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.

• 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 EDS-316 downwards, as indicated. Tighten the four screws for added stability.

ATTENTION
The equipment shall be installed in an enclosure that is only accessible using the correct tool with at least an IP54 rating in accordance with IEC/EN 60079-15. It should not be used in an area with pollution degree 2 or higher as defined in IEC 60664-1.

Wiring Requirements

WARNING
EXPLOSION HAZARD – Substitution of any components may impair suitability for Class I, Division 2.

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
Substitution of components may impair suitability for Class I, Division 2, and Zone 2. These devices must be supplied by an SELV source as defined in Low Voltage Directive 73/23/EEC and 93/68/EEC.

WARNING
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).

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.

• Only use copper conductors with 60/75°C capability

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. A 4mm 2 conductor must be used when a connection to the external grounding screw is utilized.

ATTENTION
This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel.

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 : 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:

1. EDS has lost power from one of the DC power inputs. OR
2. The PORT ALARM DIP Switch for one of the ports is set to ON, but the port is not connected properly. If neither of these two conditions is satisfied, the Fault circuit will be closed.

Wiring the Redundant Power Inputs

The top two contacts and the bottom two contacts of the 6-contact terminal block connector on EDS’s top panel are used for 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 EDS’s top panel.

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

ATTENTION

• Conductors suitable for use in an ambient temperature of 93°C must be used for the power supply terminal.
• One individual conductor in a clamping point with 28-12 AWG wire size, and a torque value of 4.5 lb-in should be used.

ATTENTION
Transient provisions shall be provided to limit the peak rated voltage to a maximum of 140% of the peak rated voltage.

Communication Connections
EDS-316 models have 14, 15, or 16 10/100BaseT(X) Ethernet ports, and 2, 1, or 0 (zero) 100BaseFX (SC/ST-type connector) fiber ports.

10/100BaseT(X) Ethernet Port Connection

The 10/100BaseT(X) ports located on 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 also show cable wiring diagrams for straight-through and cross-over Ethernet cables.

100BaseFX Ethernet Port Connection
The concept behind the SC/ST port and cable is very 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 EDS-316’s power needs.

Alarm Contact

WARNING
Exposure to some chemicals may degrade the sealing properties of materials used in the Sealed Relay Device.

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 on page 7. 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) The PORT ALARM DIP Switch for one of the ports is set to ON, but the port is not connected properly. 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 EDS-316’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-316 to Ethernet devices.

Fiber Ports
Moxa EDS-316’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/ST connector. Consequently, you should use fiber cables that have SC/ST 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.

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 5 km for multi-mode, and 40 km, and 80 km for single-mode) for installation versatility.

Dual Speed Functionality and Switching
Moxa EDS-316’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.
EDS-316 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 EDS-316 has an address table that can hold up to 4K 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-316 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 EDS-316’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. EDS-316 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 an EDS-316 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.
