MOXA Ethernet Switch, 9 Ports, Rack Mount - EDS-309-3M-ST

This compact industrial Ethernet switch connects mixed copper and fibre links within automated and industrial environments, enabling straightforward layer-2 switching for device networks. It is an unmanaged unit designed for fixed installs and rack mounting, providing deterministic connectivity where simple, continuous data forwarding is required.

Features and Benefits:

• Nine-port configuration delivers straightforward network expansion
• Six RJ-45 ports support 100BaseTX connections for legacy devices
• Three fibre ports accommodate multimode ST connectors for long links
• Supports 10BaseT operation for compatibility with older equipment
• Implements IEEE 802.3x flow control to reduce packet loss during congestion
• Complies with IEEE 802.3u and IEEE 802.3 standards for broad interoperability

Applications

• Suitable for factory-floor Ethernet segmentation and device aggregation
• Ideal for connecting control cabinets to fibre backbones
• Used with sensors and HMIs requiring mixed copper and fibre links
• Can be used for linking remote I/O over multimode ST fibre
• Suitable for industrial automation rack-mounted network panels

How is the unit mounted in an equipment cabinet?

The switch is designed for rack installation to integrate into standard rack-mounted network assemblies.

What connector type is used for the fibre links?

Fibre connections use ST multimode connectors suited to short- to medium-range optical links.

How many copper Ethernet links can be connected simultaneously?

There are six RJ-45 ports available for simultaneous 100BaseTX copper connections.

Which Ethernet standards does it support for compatibility?

It supports 10BaseT, 100BaseT(X) and 100BaseFX as defined by IEEE 802.3, IEEE 802.3u and includes IEEE 802.3x flow control.
