Page 7: Mounting Dimensions (Unit = Mm)
The aluminum DIN-Rail attachment plate should already be fixed to the back panel of EDS-308/309 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.
Page 8: Wall Mounting (Optional)
Wall Mounting (optional) For some applications, you will find it convenient to mount EDS-308/309 on the wall, as illustrated below. STEP 1: Remove the aluminum DIN-Rail attachment plate from plate ⇒ EDS-308/309’s rear panel, and then attach the wall mount...
Page 9: Wiring Requirements
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.

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. ATTENTION This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel.
Page 11: Communication Connections
ATTENTION Before connecting the EDS to the DC power inputs, make sure the DC power source voltage is stable. Communication Connections 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 also show cable wiring diagrams for straight-through and cross-over Ethernet cables.
Page 12: 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-308/309’s power needs. Alarm Contact The Moxa EtherDevice Switch has one Alarm Contact located on the top panel.

100BaseFX port is inactive Auto MDI/MDI-X Connection The Auto MDI/MDI-X function allows users to connect EDS-308’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-308/309 to Ethernet devices.

Switching and Address Learning Moxa EDS-308/309 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, EDS-308/309 automatically keeps up with new node locations.
