Hirschmann MS4128-L2P Industrial Network Management Switch    

Hirschmann MS4128-L2P belongs to the Power MICE series of two-layer modular network management industrial switches, and is a maintenance spare part for DCS backbone networks in chemical and power plants.
1. Modular slot design, compatible with MM series media modules, with a maximum expansion of 28 ports and free combination of optical and electrical ports
2. Fanless passive heat dissipation, anti vibration and anti-interference, suitable for strong electromagnetic control cabinet environments in chemical and power plants
3. Native support for HIPER Ring and RSTP ring protocols, fast self-healing of link failures, ensuring uninterrupted DCS network
4. Support VLAN, IGMP Snooping, QoS, and port security to isolate industrial control business traffic
5. DIN rail installation, supports redundant DC24V power input, reduces the risk of single point power failure

1. The whole machine has 4 Gigabit Combo ports (SFP optical/Gigabit electrical multiplexing), with a maximum of 24 100Mbps ports paired with an expansion board
2. Switching capacity of 12.8Gbps, packet forwarding rate of 9.6Mbps

4. Supports multiple network management methods including web, CLI, and SNMP, with built-in fault alarm relay output
5. Compatible with MM2 and MM3 series media modules, hot swappable and replaceable
1. Backbone network aggregation of chemical DCS system
2. Industrial Ethernet core switching in power plants and water treatment plants
3. Industrial control networking of semiconductor production line equipment
4. Replacement and repair of existing MS4128 series switches due to malfunctions
5. Reserve of network maintenance spare parts for industrial computer rooms
This MS4128-L2P is a classic layer 2 aggregation switch from the Power MICE series, which has been discontinued and is mostly used for replacing spare parts in DCS cabinets for old projects.
