## Summary description

The Moxa EDS-505A-MM-ST is a managed network switch featuring 3 RJ-45 Ethernet ports with full duplex capability. It supports various networking standards including IEEE 802.1D, 802.1p, 802.1Q, and more, making it suitable for industrial applications requiring reliable and efficient data transmission.

## Long description

The Moxa EDS-505A-MM-ST is a standalone 16-port managed Ethernet switch family; the specific EDS-505A-MM-ST model provides three RJ-45 Ethernet ports with full-duplex capability and is designed for industrial network applications that require reliable and deterministic data transmission. The EDS-505A series supports Turbo Ring and Turbo Chain redundancy technologies with sub-20 ms recovery, RSTP/STP standards, and a wide set of management, security, and protocol features including IEEE 1588 PTP and Modbus/TCP.
Advantages
The switch offers fast network recovery (Turbo Ring and Turbo Chain) and support for RSTP/STP to increase link availability. It includes precise time synchronization via IEEE 1588 PTP, Modbus/TCP for industrial protocol compatibility, and extensive management options such as SNMPv1/v2c/v3, LLDP, and DHCP Option 82. Security and operational control are provided through IEEE 802.1X, HTTPS, SSH, VLAN, QoS, IGMP snooping, port trunking, port mirroring, and MAC-based lock-port functionality.
Suitable for
Industrial automation networks requiring managed switching
Environments needing fast topology recovery and high availability
Applications that require precise time synchronization (IEEE 1588 PTP)
Systems using Modbus/TCP or IPv6-ready infrastructures
Key specifications

How to use
Install the EDS-505A-MM-ST in an appropriate industrial enclosure or mounting rail and connect the RJ-45 Ethernet ports to your network devices. Configure network redundancy (Turbo Ring/Chain or RSTP/STP) and assign VLANs, QoS, and security settings through the switch management interface (web/CLI/SNMP). If precise timing is required, enable IEEE 1588 PTP. Use SNMP, RMON, and event notification to monitor status and receive automatic alerts.
Usage recommendations
The switch is intended for industrial environments; use the model variants specified for your required operating temperature range and apply proper grounding and surge protection. Regularly update firmware and secure management access with HTTPS/SSH and SNMPv3.
