EES20-0600UHIHSH2E – Embedded Ethernet Switch with RSTP by Hirschmann

The Hirschmann EES20-0600UHIHSH2E is a managed embedded Ethernet switch from the EES series, designed for OEM integration into industrial equipment where a standalone external switch is not viable and switching intelligence must be embedded directly within the host device. It connects to the host system via two 50-pin male connectors and provides 6x Fast Ethernet ports individually configurable as 100BaseTX copper or 100BaseFX fibre, with RS232 for configuration, SPI for status signalling, and SNMP trap support. Operating from a 3.3VDC supply at just 2.9W, the EES20-0600UHIHSH2E is exceptionally power-efficient for its capability level, and its 88 x 13 x 60mm, 35-gram form factor imposes minimal space and weight overhead on the host system. The operating temperature range of -40 to +85°C makes it suitable for demanding industrial, railway, and energy applications without additional thermal management. Running Hirschmann HiOS firmware, the switch supports RSTP (IEC 62439-1), MRP redundancy as both manager and client (IEC 62439-2), LACP link aggregation, and link backup for network resilience. Industrial protocol profiles include PROFINET IO, EtherNet/IP, IEC 61850 with MMS server and switch model, and Modbus TCP. Time synchronisation is via PTPv2 boundary clock, PTPv2 transparent clock two-step, and SNTP. Security features encompass 802.1X port-based access control, RADIUS authentication, VLAN-based management restriction, MAC-based port security, DoS prevention, and audit trail. An optional protective PCB coating is available for enhanced environmental resilience. Available from Recab, your Nordic partner for Hirschmann embedded networking solutions.
