Manufactured by Hirschmann, a Belden brand, the MSP30-28-2A provides 24 Fast Ethernet ports and four Gigabit Ethernet uplinks, operating from 0 °C to +60 °C and consuming just 18 W from a 24 V DC supply within a 391 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 and egress interface shaping, Jumbo Frames, Voice VLAN, Private VLAN, Protocol-based VLAN, MAC-based VLAN, and ingress storm protection. Redundancy is delivered through HIPER-Ring as ring switch and over link aggregation, MRP per IEC 62439-2 as both client and manager, RSTP to 802.1D-2004, MSTP, LACP with link aggregation, Sub Ring Manager, link backup, and redundant network coupling. Security features include 802.1X port-based access control, 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 accurate time synchronisation. Management is available via SNMP v1/v2/v3, HTTPS, SSHv2, OPC-UA Server, CLI, and web-based management, with SD card and USB auto-configuration adapters for fast deployment. Certified to CE, FCC, cUL508, and NEMA TS2, the MSP30-28-2A is well suited to factory automation, machine building, transport infrastructure, and energy distribution switching.
