The Hirschmann RSP25-11003Z6ZT-SCCV9HPE2S is a hardened managed fanless DIN rail switch from the Hirschmann RSP25 series, providing eleven switching ports comprising four 10/100BASE-TX RJ45 copper ports and seven SFP Fast Ethernet slots supporting both single-mode and multimode fibre via compatible M-SFP and M-Fast SFP modules. Powered by dual 24/36/48 VDC inputs (18–60 VDC range) via plug-in terminal blocks with signalling contact, the switch carries a 22 W power consumption and is certified to IEC 61850-3 and IEEE 1613 for substation environments. Its enhanced feature set covers PRP (Parallel Redundancy Protocol) per IEC62439-3, HSR (High-availability Seamless Redundancy), Fast MRP per IEC62439-2, RSTP, LACP link aggregation, link backup, and HSR-PRP RedBox functionality, providing the comprehensive network redundancy demanded by process automation and critical power infrastructure. NAT with L3 routing extends the switch into network segmentation and routing scenarios. Industrial protocol support spans PROFINET, IEC61850 MMS server, EtherNet/IP, and Modbus TCP, making it compatible with the broadest range of industrial automation and protection relay systems. Switching features include IGMP snooping per VLAN (v1/v2/v3), VLAN (802.1Q), QoS per 802.1D/p, TOS/DSCP prioritisation, MMRP, MVRP, and jumbo frames. Security encompasses 802.1X port-based access control, RADIUS authentication, MAC-based port security, HTTPS certificate management, signed firmware images, DoS prevention, and VLAN-based ACL. Management is via CLI, HTTPS, SNMP v1/v2/v3, SSH, LLDP, and Hirschmann’s HiDiscovery and HTML5-based web management. An SD card slot for AutoConfiguration Adapter ACA31, PTPv2 boundary and transparent clock, and SNTP time synchronisation round out the specification. Operating 0 to +60 degrees Celsius with IEC 61850-3 and IEEE 1613 substation approval and a 60-month guarantee. Available from Recab, your Nordic partner for Hirschmann industrial switch solutions.
