Hirschmann MM20-Z6Z6Z6Z6SAHH – 4-port Gigabit Copper Media Module for MICE Modular Switches

The Hirschmann MM20-Z6Z6Z6Z6SAHH is a plug-in media module designed to expand MICE-based industrial Ethernet switches with four additional 10/100/1000BASE‑T RJ45 ports. From my experience, it’s a straightforward way to add high‑throughput copper interfaces to RSPE/MSP MICE platforms without changing your wiring concept. One thing I appreciate is how service-friendly it is—front insertion, captive screws, and immediate recognition by the host switch.

The “Z6” coding on Hirschmann media modules typically indicates a standard RJ45 10/100/1000 copper port. With four Z6 positions, you get four independent Gigabit copper ports. The “SAHH” variant is commonly specified for harsh or high‑humidity environments, which, in many cases, points to added environmental robustness compared with basic variants.

Key Features

• 4x RJ45 Gigabit ports (Z6) – Each port supports 10/100/1000BASE‑T with auto‑negotiation and auto MDI/MDIX for easy deployment.
• MICE plug‑in module – Slides into the front of compatible Hirschmann MICE switch chassis (e.g., MSP/RSPE families), no external power needed.
• Industrial build – Module design typically supports extended temperature and vibration ratings when paired with the right chassis.
• SAHH variant – Appears to be tailored for high‑humidity or harsher environments; useful in washdown, humid, or widely fluctuating climates.
• Backplane integration – All configuration and management run through the host switch OS; the module adds ports without complicating your setup.
• Status LEDs – Per‑port link/activity speeds quick diagnostics on the panel door.

Application Fields

In many cases, this module is selected where rugged Gigabit copper connections are needed near machinery or control cabinets:

• Factory automation and machine building – Connect PLCs, HMIs, vision systems, and drives at Gigabit speeds.
• Material handling and intralogistics – Add ports for scanners, controllers, and industrial PCs on conveyors or AS/RS systems.
• Transportation and wayside systems – Harsh environment cabinets that still rely on copper patching to field devices.
• Process industries – Brownfield plants where Category cabling is already in place and fiber isn’t practical.

Advantages & Value

• Fast expansion without redesign – Add four Gigabit ports to an existing MICE chassis, keeping your fiber/copper mix intact.
• Reliability in tough environments – The SAHH variant is commonly used where humidity or contaminants would worry a standard office‑grade module.
• Lower downtime – Front‑accessible installation and intuitive LEDs mean quicker swap and faster troubleshooting.
• Fleet consistency – Sticking with Hirschmann MICE helps with spare pooling, firmware consistency, and staff familiarity.
• Backed by our warranty – 365‑day coverage helps de‑risk the procurement.

Installation & Maintenance

• Cabinet and mounting – Install in a Hirschmann MICE chassis on DIN rail; allow front clearance for cabling and LED visibility; ensure cabinet ventilation.
• Wiring practices – Use industrial‑grade Cat5e/Cat6 (or higher) with proper shielding/grounding as required; keep bend radius and separation from high‑noise conductors.
• Safety – De‑energize the chassis when inserting/removing modules unless your operating procedure allows hot‑swap on the given platform; observe ESD handling.
• Routine checks – Inspect RJ45 connectors for wear, clean dust with dry air, and replace worn patch cords; verify the host switch firmware is up to date.
• Commissioning – Ports are auto‑negotiating; if you need fixed speed/duplex for legacy devices, set it via the host switch interface.

Field note: A packaging OEM told us they swapped this module into an RSPE rack to add vision cameras and an HMI on short notice—no layout changes, just a quick front install and it came up right away.

Quality & Certifications

• Certifications: CE and RoHS compliance are typical for Hirschmann industrial Ethernet modules; UL/cUL listings are common on MICE platforms.
• Manufacturer quality: Built to industrial standards for shock/vibration and EMC; aligns with Hirschmann’s established industrial Ethernet portfolio.
• Warranty: 365 days

Compatible & Supporting Components (examples)

• MICE host chassis/controllers: Hirschmann MSP and RSPE series (compatibility may depend on hardware/firmware revision).
• Power modules: MICE PM power modules sized for total chassis load.
• Alternative media modules: Fiber SFP or multi‑mode/single‑mode MICE modules if you later shift uplinks to optical.

Note: Exact environmental and compliance ratings should match the host MICE chassis specification. If you share your chassis model and firmware, we can validate plug‑and‑play compatibility before order.
