The Hirschmann RSP30-08033O6TT-SCCV9HSE2S is a hardened managed fanless DIN rail switch from the Hirschmann RSP30 series, providing eleven switching ports in a configuration of eight 10/100BASE-TX RJ45 copper ports and three dual-speed SFP slots supporting both 100 Mbit/s Fast Ethernet and 1000 Mbit/s Gigabit connections depending on the fitted M-SFP module. This Gigabit-capable SFP uplink distinguishes the RSP30 from the RSP25 Fast Ethernet-only fibre series, allowing it to serve as a Gigabit aggregation point in mixed-speed industrial ring and star topologies. Powered by dual 24/36/48 VDC inputs (18–60 VDC) via plug-in terminal blocks, it consumes 15 W. Redundancy support covers PRP per IEC62439-3, HSR per IEC62439-3, Fast MRP per IEC62439-2, RSTP, LACP link aggregation, and link backup, providing full protection for ring and star network architectures in power and process automation. Industrial protocol support includes PROFINET, IEC61850 MMS server, EtherNet/IP, and Modbus TCP. Switching features include IGMP snooping per VLAN (v1/v2/v3), VLAN (802.1Q), QoS per 802.1D/p, TOS/DSCP, MMRP, MVRP, and jumbo frames. Security covers 802.1X port-based access control, RADIUS, MAC-based port security, HTTPS, signed firmware, DoS prevention, and VLAN-based ACL. Management is via CLI, HTTPS, SNMP v1/v2/v3, SSHv2, LLDP, HiDiscovery, and HTML5 web management. An ACA31 SD card AutoConfiguration slot, PTPv2 boundary and transparent clock, and SNTP time synchronisation are included. Operating 0 to +60 degrees Celsius, certified to IEC 61850-3 and IEEE 1613 for substation use, with CE, FCC, EN61131 approval and a 60-month guarantee.
