11-Port Fast Ethernet IEC 61850-3 Industrial Managed Switch


The EH9711 series is a compact 11-port Layer2-managed switch, equipped with 8x Fast Ethernet ports and 3x Gbps SFP Fiber links. The series is designed for demanding power substation automation systems and is fully compliant with IEC 61850-3 and IEEE 1613 standards.

With IEEE1588v2 PTP and SyncE supported, the series can achieve ns-level accuracy and meet the strict time synchronization requirements in real-time applications. Self-healing ability for the network is provided with various types of ring protocols. ITU-T G.8032 ERPS Ring can even recover the network within 25 ms on full load of 250 devices.

Compliant with IEC62443-4-2 and IEC62443-4-1, it achieves both product security features and requirements for secure development life-cycle.


IEEE 1613IEC 61850-3: Compliant with IEC 61850-3 & IEEE1613 standards for power substation automation systems.

Self-Healing Network: EH9711 supports various types of ring protocols. With ITU-T G.8032 ERPS Ring, self-recovery can be done within 25ms on full load.

sFlow Monitoring: By sampling packets, administrators are able to monitor network traffic and discover abnormal situations in time.

Synchronous Ethernet: Stable frequency transport at MAC Layer to ensure services continuity from end to end.

Nanosecond Time Sync with 1588v2 PTP: IEEE1588v2 PTP support helps achieve the strict time synchronization requirements in real-time applications. Can be used as a hardware-based P2P/E2E transparent clock or boundary clock.

RBAC: Besides multiple Admin accounts with read-&-write or read-only access, ACL by MAC/IP is supported for LAN control, and 802.1x is supported to work with RADIUS/TACACS+ for LAN hosts authorization and accounting.
