The Hirschmann RSP20-11003Z6TT-SCCV9HSE2S is a managed DIN rail industrial Fast Ethernet switch belonging to the RSP20 series, providing eight 10/100 Mbit/s copper RJ45 ports and three SFP fibre slots for 100 Mbit/s fibre connectivity in an 11-port mixed-media configuration within a 90 x 164 x 120 mm fanless enclosure. Running HiOS Layer 2 firmware, it delivers PRP per IEC 62439-3, HSR per IEC 62439-3, MRP per IEC 62439-2 as both manager and client, RSTP per IEEE 802.1D-2004, and LACP, covering the full range of industrial high-availability redundancy topologies including ring, mesh, star, and line architectures with zero-downtime failover capability. The SFP slots accept single-mode, long-haul, and multi-mode fibre modules, enabling mixed copper-fibre topologies for long-distance or electrically isolated connections in substations, large plants, and campus networks. Advanced switching features include IGMP snooping per VLAN, QoS per 802.1D/p and TOS/DSCP, jumbo frames, and MMRP/MVRP, while industrial protocol support covers PROFINET, EtherNet/IP, Modbus TCP, and IEC 61850 MMS server and switch model for direct automation and substation platform interoperability. Security encompasses 802.1X port access control, RADIUS authentication, MAC-based port security, VLAN-based and ingress ACLs, denial-of-service prevention, signed firmware images, and HTTPS certificate management. PTPv2 transparent and boundary clock with 802.1AS support provides precision time synchronisation. The dual 24/36/48 VDC redundant power input operates across 18–60 VDC with 35 V/m EMC immunity. Certified to CE, FCC, EN61131, IEC 61850-3, and IEEE 1613 with a 60-month guarantee. Available from Recab, your Nordic partner for Hirschmann industrial switch solutions.
