The Hirschmann BOBCAT BRS40-20TX/4SFP-EEC is the Extended Environmental Class variant of the 24-port all-Gigabit BOBCAT switch, combining 20 x 10/100/1000BASE-TX RJ45 ports with four SFP slots in a hardened metal housing rated from -40 to +70°C. Part number 942170068, it is engineered for demanding outdoor, railway, and heavy industrial installations where high port density, fiber connectivity, and wide temperature tolerance must coexist in a compact DIN Rail form factor. Like all BOBCAT switches, it supports IEEE 802.1Qbv Time-Sensitive Networking, enabling deterministic scheduling of real-time traffic without hardware upgrades. The SFP slots support single-mode, multimode, and long-haul fiber modules, while the 20 copper ports deliver full Gigabit throughput to connected devices. Redundancy is provided by HIPER-Ring, MRP (IEC62439-2), RSTP, and LACP link aggregation. The industrial protocol stack includes PROFINET, EtherNet/IP, IEC61850, and Modbus TCP. Security features cover 802.1X, RADIUS, secure boot, signed firmware, and VLAN-based ACL. Dual redundant 12–24 VDC inputs power the unit at 19 W. Management options include USB-C, HTML5, CLI scripting, and SNMP v1/v2/v3. The BRS40-20TX/4SFP-EEC is the switch of choice for engineers designing resilient, high-density Gigabit networks in railway infrastructure, outdoor substations, offshore platforms, and cold climate manufacturing facilities.
