The Hirschmann MSP30-20-2A, configurator code MSP30-16040SCY999HHE2A, is a modular Gigabit Ethernet industrial DIN rail switch from the MSP30 family running HiOS Layer 2 Advanced software, built for industrial network engineers who need a well-featured and reliable Layer 2 switch in a space-efficient fanless DIN rail chassis. Manufactured by Hirschmann, a Belden brand, the MSP30-20-2A provides 16 Fast Ethernet ports and four Gigabit Ethernet uplinks operating between 0 °C and +60 °C, consuming just 17 W from a 24 V DC supply within a 314 x 148 x 142 mm chassis. Switching features include IGMP Snooping and Querier per VLAN for v1/v2/v3, DiffServ ingress and egress classification and policing, QoS to 802.1D/p with queue shaping, Jumbo Frames, Voice VLAN, Private VLAN, and storm protection. Redundancy is delivered by HIPER-Ring as ring switch and over link aggregation, MRP per IEC 62439-2 as both client and manager, RSTP, MSTP, LACP, Sub Ring Manager, link backup, and redundant network coupling. Security includes 802.1X, RADIUS, TACACS+, DHCP Snooping, Dynamic ARP Inspection, IP Source Guard, LDAP, configurable password policy, time-based ACLs, and user account locking. Industrial profiles support PROFINET, EtherNet/IP, Modbus TCP, and IEC 61850, while PTPv2 Boundary and Transparent Clocks enable precise time synchronisation. Management is via SNMP v1/v2/v3, HTTPS, SSH, OPC-UA Server, CLI, and web-based management with SD card and USB auto-configuration support. Certified CE, FCC, cUL508, and NEMA TS2, the MSP30-20-2A suits factory automation, machine building, transport infrastructure, and energy switching applications.
