Industrial managed switches

Moxa EDS-4000/G4000 Ethernet switches help build future-proof industrial networks to strengthen operational resilience in industrial spaces such as power, transportation, maritime, and factory automation
Moxa has announced that it has upgraded its flagship EDS-4000/G4000 Series of controlled Ethernet switches with support for MX-NOS firmware version 4.0 (V4.0).

The company says the new firmware brings enhanced diagnostics, hardened security measures, and more powerful capabilities to the world’s first IEC 62443-4-2 certified line of Ethernet switches. The EDS-4000/G4000 Series now numbers 68 switch models, all designed to accelerate digital transformation in industrial spaces such as power, transportation, maritime, and factory automation.

Adhering with IEC 62443-4-1, the MX-NOS firmware platform enables expandability in Moxa EDS-4000/G4000 Series switches, allowing for the addition of new functions and features throughout the device’s lifetime. By ensuring the switches share a consistent functionality and intuitive interface, MX-NOS V4.0 also enhances the user experience. MX-NOS V4.0 works seamlessly with Moxa MXview network management software to simplify operations throughout industrial operations.

As industrial applications continue to evolve, OT architectures require enhanced network security. Recognising this, MX-NOS V4.0 brings DHCP Snooping to EDS-4000/G4000 Series switches. A layer 2 security technology, DHCP Snooping filters and drops DHCP traffic determined to be unacceptable, preventing rogue DHCP servers from accessing the OT network using “man-in-the-middle” attacks.

Strengthening operational resilience requires fast, accurate diagnosis of network issues to detect root causes. MX-NOS version 4.0 has added two important diagnostic tools to its arsenal: RSPAN port mirroring and a user-defined fibre check. Both limit network downtime. RSPAN lets administrators mirror traffic from source ports onto a VLAN, allowing session traffic to be transported across multiple switches. As its name implies, fibre check shows the interface status of fibre connections on the switch.

As the number of connected devices in industrial operations grows exponentially, managed switches be more flexible while offering higher reliability. That’s why MX-NOS V4.0 incorporates new features including Media Redundancy Protocol, IEEE 1588 PTP for time synchronisation, along with support for Modbus TCP, Ethernet/IP and PROFINET.

Media Redundancy Protocol or “MRP” uses a ring to provide redundancy in Ethernet networks. Ring networks with up to 50 devices can use MRP, which ensures entirely predictable switchover behaviour.

IEEE 1588 PTP (Precision Time Protocol) synchronises clocks throughout a network in the sub-microsecond range for measurement and control systems.

Support for EtherNet/IP and Modbus TCP protocols provides device management and monitoring, while compatibility with PROFINET enables transparent data transmission.
