Description
Product Overview
The Hirschmann MM2-4TX1 943722101 is a copper Ethernet media module designed for the Hirschmann MICE modular industrial switch platform. The module provides four RJ45 twisted-pair Ethernet ports, allowing engineers to expand the connection capacity of compatible MICE switch assemblies without replacing the complete switch chassis. The Hirschmann MM2-4TX1 943722101 supports 10BASE-T and 100BASE-TX communication and is commonly used in industrial automation networks connecting PLCs, remote I/O stations, HMIs, industrial PCs, and field communication devices.
Installed through the MICE switch backplane, the Hirschmann MM2-4TX1 943722101 receives power directly from the host switch assembly and provides copper network connectivity through standard RJ45 interfaces. The module includes Ethernet functions such as auto-negotiation, auto-crossing, and auto-polarity, reducing manual network configuration during installation. Diagnostic LEDs provide visibility of power, link status, data activity, transmission speed, and duplex conditions, which helps maintenance teams troubleshoot communication issues in operating plants.
The Hirschmann MM2-4TX1 943722101 is commonly maintained in existing industrial Ethernet infrastructures where modular MICE switches remain installed and operational. Typical applications include manufacturing networks, process automation systems, transportation control systems, and plant-floor communication backbones. Before replacement, engineers should confirm the installed MICE switch chassis model, available module slots, port requirements, and existing network topology. To be completely transparent, this is an expansion media module rather than a standalone Ethernet switch; it cannot operate independently and must be installed into a compatible Hirschmann modular switch platform.
Product Introduction (Non-Templated)
A missing communication port on an industrial switch can force unnecessary network redesign when the actual issue is only insufficient interface capacity. The Hirschmann MM2-4TX1 943722101 adds four copper Ethernet connections to compatible MICE switch systems.
Designed for industrial Ethernet expansion, this module provides 10/100BASE-TX RJ45 connectivity with backplane power, making it suitable for PLC network extensions, machine cell integration, and legacy switch maintenance projects.

Frequently Asked Questions (FAQ)
1. Is the Hirschmann compatible with my existing industrial Ethernet switch?
The module is compatible with specific Hirschmann MICE modular switch platforms.
Before installation, verify:
- Host switch model (MS20, MS30, MS4128 family)
- Available media module slot
- Existing firmware compatibility
- Required copper/fiber port arrangement
The is not a standalone Ethernet switch.
2. Can I hot-swap this?
The is designed as a modular switch component, but hot replacement depends on the host MICE switch model and operating conditions.
Recommended procedure:
- Save switch configuration
- Confirm network redundancy status
- Remove the affected module according to maintenance procedures
- Install the replacement module
- Verify link and communication status
Critical control networks should be placed into a controlled maintenance condition before changes.
3. Does the support firmware v3.1?
The module itself does not operate as an independent programmable device.
Firmware compatibility depends on:
- Host MICE switch firmware
- Switch management software
- Installed module combination
- Network configuration
The media module must match the firmware environment of the installed switch platform.
4. Will I lose my network configuration when replacing the ?
The module does not normally store the main switch configuration.
Configuration items such as:
- VLAN settings
- Network addresses
- Redundancy parameters
- Port configuration
are managed by the host switch system. Always back up the switch configuration before replacement.
5. How can I verify a New Surplus Hirschmann is authentic?
Recommended inspection points:
- Confirm model marking:
- Verify order number 943722101
- Inspect RJ45 connectors
- Check module housing condition
- Confirm backplane connector integrity
For industrial communication hardware, correct model identification is essential because similar media modules may use different switch families.
6. Can the support a legacy industrial Ethernet upgrade?
Yes, when the existing network is based on Hirschmann MICE modular switches.
Common applications:
- Adding PLC communication ports
- Expanding remote I/O connections
- Restoring damaged switch modules
- Maintaining installed Ethernet infrastructure
The host switch architecture should be confirmed before adding expansion modules.
7. What should engineers check before commissioning this module?
Key verification steps:
- Confirm compatible MICE switch chassis
- Install the module correctly
- Verify power recognition
- Check link status
- Test connected devices
- Confirm network communication
These checks confirm the new media module is functioning correctly within the industrial Ethernet system.
