The Hirschmann BOBCAT BRS42-8TX/4SFP is a compact all-Gigabit managed industrial DIN Rail switch combining eight 10/100/1000BASE-TX RJ45 ports with full IEEE 802.3at PoE+ on all copper ports and four SFP slots for 100 or 1000 Mbit/s fiber uplinks, providing 12 ports in total. Part number 942170046, it delivers up to 240 W total PoE budget from dual redundant 48/54 VDC inputs, enabling the simultaneous powering of IP cameras, wireless access points, VoIP terminals, and industrial IoT devices without separate power supplies, while maintaining fiber backbone connectivity via the SFP slots which support single-mode, long-haul, and multimode transceivers. Operating from 0 to +60°C in a 550 g PC-ABS housing measuring 73 x 138 x 115 mm, the BRS42-8TX/4SFP is part of the Hirschmann BOBCAT TSN series and supports IEEE 802.1Qbv for deterministic real-time Ethernet — a combination of PoE+ delivery and TSN scheduling that is rare among compact DIN Rail switches. PoE management features include PoE Fast Startup and manual per-port power management. The switching stack covers HIPER-Ring and MRP (IEC62439-2) redundancy, RSTP, LACP, IGMP snooping, QoS, and VLAN management. Industrial protocol support spans PROFINET, EtherNet/IP, IEC61850 MMS Server, and Modbus TCP. Security features include 802.1X, RADIUS, secure boot, signed firmware, and DoS prevention. Management is via USB-C, HTML5, CLI, and SNMP v1/v2/v3. The BRS42-8TX/4SFP is the right choice for factory, building, and surveillance network engineers needing both PoE+ device powering and fiber backbone uplink capability in the most compact possible housing.
