Network Switch Modules 

Meet our new Network Switch Modules for your special network projects.

All Network Switch Modules are powered by Marvell Ironman processors – the first 10G processors, developed specifically for Industry 4.0 and IoT applications, supporting TSN/HSR.

Designed to deliver a full portfolio of scalable, high-performance, low-power, small-footprint, feature-rich Ethernet switches, optimized for industrial and Internet of Things (IoT) applications operating in extended temperature range and harsh environments.



  • Integrated PHY
  • On-board magnetic
  • Jumbo Frames support
  • Cut-through operation to minimize traffic latency 
  • IEC 62439-3 – HSR/PRP High available seamless redundancy (Parallel Redundancy Protocol)
  • Time-Sensitive Networking (TSN) IEEE
  • Parallel (x8) and Serial LED interface for port activity status
  • Highly scalable (cascade up to 1K modules)

Processor, Memory, and Security

  • Dual-Core ARMv8 up to 1.2 GHz
  • High bandwidth DDR4 (1G /2G options)
  • eMMC (up to 256G)
  • Secured boot/storage
  • IEEE 802.3ae standard compliant 256b MACsec engine with capacity to process, encrypt and decrypt the entire devices bandwidth bi-directionally traffic (optional)
  • OOB 1GE ethernet interface
    *Optional assembly possible with internal CPU disabled and PCIe Gen3 Device connection instead of OOB.


  • RS232 CLI out of band management for secure installations
  • Support for fast boot
  • Management software (TBD)

Low power consumption
Optional PoE (PSE/PD
Support for industrial extended temperature range
