HIRSCHMANN MM20-Z6Z6T1T1EBH Technical Datasheet & Overview

HIRSCHMANN MM20-Z6Z6T1T1EBH Technical Datasheet & Overview

Product Introduction / Overview

The Hirschmann MM20-Z6Z6T1T1EBH is an industrial-grade, hot-swappable Media Module designed for deployment in Hirschmann MNS20.

MS20. MS30. and PowerMICE modular Ethernet switches.

This specific configuration provides flexible, high-density Fast Ethernet connectivity, combining 2x MTRJ Fiber Ports (Multimode) and 2x RJ45 Copper Ports. 

It enables seamless bridging between long-distance fiber backbones and local copper field devices in demanding automation, transportation, and energy sector environments.

Technical Parameter List

Product Features / Core Advantages

High-Density Hybrid Connectivity: Integrates fiber optic and copper communication within a single modular slot to optimize control cabinet space.

Compact MTRJ Form Factor: Uses MTRJ connectors to deliver dual-channel fiber links in a minimal physical footprint compared to traditional ST or SC connectors.

Hot-Swappable Design: Allows engineers to install or swap the module without shutting down or interrupting power to the switch chassis.

Industrial Durability: Designed without fans or moving parts, offering immunity to strong electromagnetic interference (EMI/RFI).

Plug-and-Play Integration: Automatically recognized by Hirschmann switch backplanes running HiOS or Classic Software.

Installation Method

1.Verify Power & Chassis Compatibility：Pre-installation。

Confirm that the target switch base unit (e.g., MS20. MS30. MNS20) is powered or ready for hot-swapping. Inspect the rear backplane connectors for dirt or debris.

2.Align the Module：Mechanical Mounting。

Slide the MM20-Z6Z6T1T1EBH module straight into the designated module slot along the guide rails until the backplane connector fully seats into the main switch body.

3.Secure Screws：Fixation。

Hand-tighten the top and bottom captive retaining screws using a flathead screwdriver to ensure grounding continuity and physical security.

4.Connect Network Cables：Cabling。

Plug the MTRJ fiber connectors into Ports 1 & 2 (check RX/TX orientation) and standard RJ45 Cat5e/6 cables into Ports 3 & 4.

Operating Instructions & LED Status Guide

Upon insertion, the modular switch automatically detects the MM20 module. System diagnostic LEDs on the module faceplate provide real-time operational feedback:

P (Power LED):

Green: Power supplied successfully from backplane.

Off: No power or improper insertion.

Port Link/Data LEDs (Ports 1 to 4):

Solid Green: Link established (100 Mbps).

Flashing Green: Port actively transmitting or receiving data.

Off: Cable disconnected, no link detected, or line fault.

Maintenance Note: Ensure MTRJ fiber face ends are cleaned with an optical cleaning tool before insertion to prevent dust contamination, which can cause high attenuation on 1300 nm optical links.
