Hirschmann MM20-Z6Z6Z6Z6SBH – Modular Industrial Ethernet Media Module for Flexible Port Expansion

The Hirschmann MM20-Z6Z6Z6Z6SBH is a factory-configured MM20 media module designed to expand ports on compatible Hirschmann modular switches. From my experience, these MM20 options are used when you want to tailor the exact copper/fiber mix per slot without replacing the whole switch. The “Z6Z6Z6Z6” coding indicates a specific four-block port configuration defined by Hirschmann at production; it typically denotes identical port groups, which keeps spares planning predictable. If you’re refreshing legacy lines or standardizing new panels, this kind of plug-in module streamlines the job and avoids unexpected rewiring work.

Key Features

• Modular port expansion – Adds the exact interface set your network needs without changing the chassis.
• Factory-configured port map – The Z6Z6Z6Z6 code denotes four identical configuration blocks, which typically simplifies sparing and documentation.
• Industrial temperature design – In many cases rated for extended temperatures used on factory floors and in control cabinets.
• Chassis-powered, plug-in form factor – No separate power wiring; installation is usually a quick slot-in with proper ESD handling.
• Layer 1/2 Ethernet compatibility – Built for IEEE 802.3 compliant Fast/Gigabit Ethernet modules (specifics depend on the Z6 option set).
• Service-friendly – You might notice that diagnostics and labeling align with Hirschmann’s standard conventions, making maintenance easier for mixed teams.

Application Fields

This module is geared for industrial networks where uptime and tailored port mixes matter:

• Discrete manufacturing and assembly lines needing fast changeover on machine cells
• Process industries (chemicals, water/wastewater) where fiber runs and EMI resilience are common
• Material handling and logistics conveyors that combine copper drops with backbone fiber
• Transportation and tunnel cabinets that typically require extended temperature and robust connectors

A maintenance lead from a packaging plant told us they use MM20 modules to keep a common switch platform while switching between RJ45 on short runs and SFP fiber to reach the mezzanine. “Swapping the module took fifteen minutes and we didn’t touch the PLC network,” was the comment—pretty typical when the chassis stays put.

Advantages & Value

• Cost control – Add interfaces when needed; avoid overspecifying the base chassis.
• Reliability – Industrial-grade construction and a tight mechanical fit reduce vibration-related issues in many cases.
• Compatibility – Built to operate within Hirschmann’s modular ecosystem, easing lifecycle management and spares.
• Service & support – Firmware and diagnostics align with established Hirschmann practices, so teams ramp up quickly.

Installation & Maintenance

• Cabinet environment – Use a clean, ventilated control cabinet. Keep ambient within the module’s rated range (typically -40…+70°C).
• Wiring – Observe bend radius for fiber, use shielded twisted pair for copper in high-EMI zones, and verify grounding continuity.
• Mounting – Power down the chassis unless hot-swapping is supported by the specific host model. Use ESD precautions; seat the module fully and tighten retaining hardware.
• Routine maintenance – Inspect connectors quarterly, clean fiber ports with approved tools, and review switch firmware notes for relevant updates.
• Documentation – Label the slot with the full model (MM20-Z6Z6Z6Z6SBH). You might notice that consistent labeling saves time during audits.

Quality & Certifications

• CE conformity (EMC/Low Voltage)
• cULus listing for industrial control equipment (varies by sub-variant)
• RoHS and REACH compliant materials
• Manufactured under ISO 9001 quality systems
• Manufacturer’s warranty: typically 1 year; our coverage: 365 days

Supporting Components & Typical Pairings

To make deployment smoother, many teams pair this module with:

• Compatible Hirschmann modular switch chassis that accept MM20 media modules
• Industrial SFP transceivers (for MM20 variants that use SFP cages)
• Shielded RJ45 patch cords / industrial MRP-ready cabling as required
• Managed switch firmware aligned to your network features (RSTP/MRP/HSR/PRP as applicable to the host)
• DIN-rail power supplies and cabinet accessories to maintain thermal headroom

If you’d like, share your existing chassis part number and the port types you plan to add. We’ll verify MM20-Z6Z6Z6Z6SBH compatibility and confirm the exact Z6 interface details before we ship. One thing I appreciate is how predictable these builds become once the slot map is locked in.
