Hirschmann MM20-Z6Z6Z6Z6EAHH – Industrial 4-port SFP media module for MICE switches

The Hirschmann MM20-Z6Z6Z6Z6EAHH is a plug-in media module designed for the MICE modular switching platform. It typically provides four SFP uplink ports (Z6 type), giving you flexible 100/1000BASE‑X connectivity with your choice of fiber or copper SFPs. From my experience, this module is a straightforward way to expand fiber capacity on MS20/MS30/MSP-series MICE switches without changing your base unit, which keeps projects on schedule and budgets in check.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Four flexible SFP ports (Z6) – Typically supports 100/1000BASE‑X via standard SFP transceivers, so you can mix single‑mode, multi‑mode, or copper SFPs as needed.
• Extended temperature “E” variant – Built for harsh environments; in most cases rated for -40 to +70 °C on compatible MICE bases.
• Backplane powered – No external power wiring; the host MICE switch supplies power and management.
• Industrial robustness – Metal front plate and secure fastening for vibration-prone cabinets; seems to be a good fit for transportation or energy applications.
• Unified management – Port diagnostics, alarms, and link settings handled through the host switch (web/CLI/SNMP), which simplifies maintenance.
• Field-replaceable – Swapping modules is quick; you might notice less downtime when expanding or servicing fiber uplinks.

Technical Specifications

Application Fields

This module suits fiber-heavy industrial networks where link distance, EMI immunity, or redundant ring topologies are critical. Typical use cases include:

• Factory automation lines connecting remote cells over multi-mode or single‑mode fiber
• Power and utility substations using fiber to segment protection and control IED networks
• Transportation systems (rail, tunnels) where vibration resistance and -40…+70 °C operation matter
• Oil & gas and water/wastewater plants requiring fiber backbones across distributed sites

Advantages & Value

• Lifecycle-friendly – Expands fiber ports on existing MICE bases, so you avoid replacing whole switches.
• Interoperable – Works with standard Hirschmann SFPs (100/1000BASE‑X). That flexibility typically lowers spares costs.
• Rugged and dependable – Extended temperature and mechanical stability help maintain uptime in tough cabinets.
• Simplified maintenance – Unified configuration/diagnostics through the host switch reduces service time.

“We added MM20 modules to extend two fiber rings without touching the backbone. It saved us a shutdown and the links came up clean with existing SFPs.” – Maintenance Supervisor, food processing plant

Installation & Maintenance

• Cabinet & mounting – Install on a Hirschmann MICE base mounted to DIN rail or panel in a ventilated control cabinet. Keep adequate airflow around the switch stack.
• Wiring & fiber care – Observe fiber bend radius, clean connectors, and use the correct SFP for distance and wavelength. From my experience, dust caps and strain reliefs prevent most intermittent issues.
• Power safety – De-energize the host base before adding or removing modules unless your site procedure approves otherwise.
• ESD protection – Use antistatic handling for SFPs and the module front.
• Routine upkeep – Periodically review link alarms, clean fiber termini, and keep the host switch firmware current for the latest SFP and diagnostic support.

Quality & Certifications

• Manufacturer certifications commonly include CE and cULus; RoHS compliance is typical for current Hirschmann MICE modules.
• ISO 9001 quality system at the manufacturer level.
• Warranty: 365 days (supplied by us).

Recommended Supporting Components

• Hirschmann 100/1000BASE‑X SFP transceivers (SX, LX, ZX, BiDi) to match distance and fiber type
• DIN‑rail fiber management accessories and LC/SC patch cords with industrial-rated jackets
• Pre-terminated fiber trunks for cabinet-to-cabinet runs to speed commissioning
