The Hirschmann RSPE35-24044O7T99-SCCZ999HHME2AXX is a compact, fanless enhanced managed industrial Ethernet switch from the RSPE35 series, representing Hirschmann’s most feature-complete modular DIN rail platform with the addition of Time-Sensitive Networking (TSN), Device Level Ring (DLR), PRP, Fast MRP, HSR, and NAT capabilities beyond those found in the standard RSPE30. The base unit provides eight 10/100 Fast Ethernet TX ports and four Fast/Gigabit Ethernet combo RJ45/SFP ports, expandable to 28 ports via two media module slots, and is powered by dual 24/48 VDC inputs in the 18–60 VDC range. The redundancy suite covers MRP, HIPER-Ring, HIPER-Ring over Link Aggregation, MSTP, Sub Ring Manager, Redundant Network Coupling, and RSTP guards, with the enhanced tier adding Fast MRP, HSR, and PRP for zero-recovery-time ring protection. TSN support positions this switch for next-generation deterministic automation networks where bounded latency is required. The advanced switching suite includes QinQ, DiffServ classification, IP subnet-based and MAC-based VLANs, while management adds OPC-UA Server, ITxPT Module Inventory, IPv6 Management, and Service Discovery for IIoT integration. Security encompasses LDAP, 802.1X multi-client authentication, Dynamic ARP Inspection, DHCP Snooping, time-based ACLs, and MAC Authentication Bypass. With an MTBF exceeding 2.2 million hours at 25°C, CE, FCC, and RCM certification, and native support for PROFINET, EtherNet/IP, Modbus TCP, and IEC 61850, this switch is an ideal choice for advanced manufacturing automation, smart grid integration, and IIoT plant networking across Nordic and Baltic markets.
