The Hirschmann MS4128-L2P is a high-performance managed Ethernet switch designed for mission-critical industrial networks requiring Layer 2 switching capabilities. Part of the MACH 4000 series, this 28-port ruggedized switch combines 24x 10/100BASE-TX copper ports with 4x 1000BASE-SX multi-mode fiber ports, enabling seamless integration of factory floor devices with enterprise-level SCADA systems. The MS4128-L2P’s MICE Level 2E certification ensures reliable operation in environments with moderate dust and vibration, such as automotive assembly lines.
Featuring Hirschmann’s patented HiVision network management system, the Hirschmann MS4128-L2P supports advanced traffic prioritization (IEEE 802.1p) and VLAN segmentation for discrete manufacturing applications. Its -40°C to +75°C operating range (-T models) makes it suitable for outdoor cabinet installations in oil & gas pipelines. The switch’s dual power inputs (24VDC/48VAC) with <20ms failover time guarantee continuous operation in pharmaceutical batch process controls.

Key Features and Advantages:
Network resilience: The MS4128-L2P achieves <200ms network recovery through Rapid Spanning Tree Protocol (RSTP), essential for continuous operation in glass manufacturing furnace controls. Built-in IGMP snooping v3 optimizes multicast traffic for video surveillance systems.
Industrial hardening: Zinc-coated steel housing withstands 5g vibration (IEC 60068-2-6) in mining conveyor systems. The conformal-coated PCB resists chemical exposure in wastewater treatment plants.
Smart management: Command-line interface (CLI) and web-based GUI support SNMPv3 for secure configuration of food & beverage packaging lines. Port mirroring enables real-time traffic analysis without production interruption.
Application Areas:
The Hirschmann MS4128-L2P excels in:
- Discrete Manufacturing: Machine tool networks with PROFINET IRT requirements
- Energy Management: Wind turbine SCADA communication backbones
- Transportation: Railway signaling systems (EN 50155 compliant)
- Process Industries: DCS network segmentation in chemical plants
In automotive paint shops, the switch’s IP30 rating protects against overspray contamination while maintaining 1Gbps uplink speeds. Power substations utilize its IEC 61850-3 compliance for GOOSE message transmission. The SFP slots enable flexible fiber connections (up to 550m) between control rooms and remote RTUs in LNG terminals.

Installation and Maintenance:
Installation preparation: Verify DIN rail spacing (35mm) and grounding continuity before mounting MS4128-L2P. Maintain 50mm clearance on both sides for proper heat dissipation in enclosed electrical cabinets.
Maintenance recommendations: Perform firmware updates annually using Hirschmann HiUpdate tool to maintain cybersecurity compliance. Clean air vents quarterly with dry compressed air (<1 bar pressure). Monitor port statistics monthly through HiVision’s traffic analysis module to detect early network anomalies.
