HIRSCHMANN MM20-Z6Z6M2M2SAHH Hybrid Fast Ethernet Media Module

HIRSCHMANN  MM20-Z6Z6M2M2SAHH  Hybrid Fast Ethernet Media Module

HIRSCHMANN MM20-Z6Z6M2M2SAHH (order designation: MM20-Z6Z6M2M2SAHH...) is a hot-swappable hybrid Fast Ethernet Media Module designed for Hirschmann’s modular MICE (Modular Industrial Communication Equipment) Switch family (MS20 and MS30 series).

This module pairs 2 Fast Ethernet SFP slots with 2 fixed Multimode SC fiber optic ports (100Base-FX). It offers a specialized optical-only solution that combines pluggable transceiver flexibility with dedicated fixed multimode fiber connectivity in a single slot.

Product Introduction / Overview

Hirschmann MM20-Z6Z6M2M2SAHH is a 4-port Fast Ethernet optical media module integrating 2 x SFP transceiving slots and 2 x fixed multimode SC fiber ports for MS20/30 modular switch backplanes. Designed for standard industrial operating environments ($0^circtext{C}$ to $+60^circtext{C}$), it allows network architects to bridge flexible long-haul or specialized SFP fiber runs with fixed local multimode SC fiber links—all within a single hot-swappable module without disrupting live network operations.

Technical Parameter List

Product Features / Core Advantages

All-Optical Hybrid Design: Combines customizable pluggable SFP slots with cost-effective fixed SC multimode ports, eliminating copper wiring entirely for complete electromagnetic immunity.

Flexible SFP Slots: The SFP cages accept single-mode, long-haul, or specialized SFP transceivers, giving the module multi-distance optical versatility.

Hot-Swappable Backplane Architecture: Easily plugs into active MS20 or MS30 basic switch units, enabling online maintenance or transceiver swaps without taking down adjacent modules.

Complete EMI/RFI Noise Immunity: Optical fiber transmission shields data signals from heavy motors, high-voltage switchgear, and ground loops.

Comprehensive Diagnostic LEDs: On-board LEDs provide immediate physical feedback for power supply, individual port link status, speed, and duplex status.

Model Classification

Within the Hirschmann MICE MM20/MM30 series, media modules are classified by port mix, connector interface, and environmental protection level:

Environmental Tolerance Conditions

Operating Temperature Range: $0^circtext{C}$ to $+60^circtext{C}$ (Standard industrial rating).

Storage Temperature Range: $-40^circtext{C}$ to $+70^circtext{C}$.

Relative Humidity: 10% to 95% (Non-condensing).

Vibration & Shock Resistance: Compliant with IEC 60068 standards (up to 15g shock duration at 11 ms).

EMC Immunity: Heavy industrial ratings compliant with EN 61000-4-2 (ESD), EN 61000-4-4 (Burst), and EN 61000-4-5 (Surge).

Installation Method

ESD Safety Precautions: Put on an anti-static grounding wrist strap before handling the module.

Module Insertion:

Align the guide rails of the MM20-Z6Z6M2M2SAHH with an open slot on the host MS20 or MS30 switch frame.

Push the module in firmly until the backplane connector locks into position.

Mechanical Securing: Hand-tighten top and bottom captive thumbscrews on the faceplate to ground the module chassis to the switch rack.

Cabling Connections:

SFP Slots: Slide approved Fast Ethernet SFP transceivers into slots until latched, then connect fiber patch cables.

Fixed SC Ports: Remove protective dust caps from SC ports and insert duplex SC multimode fiber patch cords (verify Tx to Rx optical alignment).

Operating Instructions

Hot-Swap Maintenance: Modules can be inserted, swapped, or serviced while the parent switch is powered on without causing software errors or requiring a system reboot.

Diagnostic LED Status Reading:

Link/Data LED (Solid Green): Valid physical connection established.

Blinking Green/Yellow: Active network packet processing.

LED Off: Cable disconnected, improper optical Tx/Rx alignment, or cable distance limit exceeded.

Port Protection: Keep protective rubber plugs inserted in unpopulated SFP slots and SC optical jacks to prevent airborne dust accumulation on internal optical lenses.
