HIRSCHMANN MM20-Z6Z6Z6T1SAHH media module.

Here is the complete, structured technical profile for the HIRSCHMANN MM20-Z6Z6Z6T1SAHH media module.

Product Introduction / Overview

The HIRSCHMANN MM20-Z6Z6Z6T1SAHH is a 4-port Fast Ethernet media module designed for Belden Hirschmann MICE (Modular Industrial Communication Equipment) switch series, including the MS20 and MS30 basic switches.

Unlike copper-heavy modules, this configuration is optimized for high-density optical aggregation. It features 3 x Fast Ethernet SFP slots (Z6Z6Z6) and 1 x 10/100Base-TX RJ45 copper port (T1), making it an ideal expansion module for industrial control cabinets that aggregate multiple fiber-optic links from remote nodes alongside a single local maintenance or PLC copper drop.

Technical Parameter List

Product Features / Core Advantages

High Optical Uplink Density: Offers 3 pluggable SFP slots in a single module bay, allowing multi-directional fiber connections back to central ring topologies.

Flexible Fiber Types: SFP compatibility lets engineers mix multimode (MM) and single-mode (SM) optical connections on the same card depending on distance needs.

Hot-Swappable Backplane: Can be inserted or replaced on a live MS20/MS30 switch chassis without disrupting power or data on adjacent modules.

Industrial Noise Shielding: Heavy metal/polycarbonate casing protects signals from high EMI environments (substations, factory floors).

Front-Panel Status LEDs: Dedicated diagnostic LEDs provide immediate visual feedback for link presence, data traffic, and line speed per port.

Model Classification (Part Number Structure)

The designation MM20-Z6Z6Z6T1SAHH follows Hirschmann’s MICE product matrix breakdown:

$$\text{MM20} – \underbrace{\text{Z6Z6Z6}}_{\text{3x SFP Slots}} \, \underbrace{\text{T1}}_{\text{1x RJ45 Copper}} \, \underbrace{\text{S}}_{\text{Standard Temp}} \, \underbrace{\text{A}}_{\text{Standard Feature}} \, \underbrace{\text{HH}}_{\text{Hardware Rev.}}$$

MM20: Fast Ethernet Media Module (100 Mbps backbone).

Z6Z6Z6: 3 x Fast Ethernet SFP Transceiver Slots.

T1: 1 x Twisted Pair / RJ45 10/100Base-TX Port.

S: Temperature Grade — Standard ($0^\circ\text{C}\text{ to }+60^\circ\text{C}$).

A: Standard Industrial Approvals (cUL508).

HH: Hirschmann hardware design / release code.

Environmental Tolerance Conditions

Operating Temperature: $0^\circ\text{C}$ to $+60^\circ\text{C}$ ($32^\circ\text{F}$ to $140^\circ\text{F}$)

Storage Temperature: $-40^\circ\text{C}$ to $+70^\circ\text{C}$ ($-40^\circ\text{F}$ to $158^\circ\text{F}$)

Relative Humidity: 10% to 95% (non-condensing)

Vibration Resistance: IEC 60068-2-6 ($1\text{g}$, 10 Hz–150 Hz)

Shock Resistance: IEC 60068-2-27 ($15\text{g}$ shock, 11 ms duration)

Enclosure: IP20 (intended for installation in IP54+ control panels)

Installation Method

1.ESD Grounding Safety：1 min。

Wear an ESD wrist strap connected to cabinet earth ground before removing the card from its anti-static bag to prevent electrostatic damage.

2.Slot Alignment：30 seconds。

Align the side rails of the MM20-Z6Z6Z6T1SAHH with an empty module slot on the target MS20/MS30 switch chassis.

3.Insert & Fasten：1 min。

Push the module firmly into the backplane until completely seated. Hand-tighten top and bottom captive thumbscrews to secure the unit against cabinet vibration.

4.Cabling Setup：2 min。

• SFP Ports (Z6): Insert M-FAST SFP transceivers into slots 1-3 until locked, then attach optical LC connectors.

• Copper Port (T1): Plug a standard Cat5e/Cat6 shielded RJ45 cable into the copper jack until the latch clicks.

Operating Instructions

Self-Test on Insertion: Upon hot-swapping into an active MS20/MS30 switch, the module will initialize via backplane power. Port status LEDs will illuminate.

Checking Port Link Status:

Solid Green: Link established (100 Mbps).

Flashing Green/Yellow: Active data transmission/reception.

OFF: Cable disconnected, unpowered remote device, or bad fiber connection.

Live Replacement: To service the module, unlatch cable connectors, loosen the captive thumbscrews, and pull the module out. The switch management system will dynamically log the hardware change.

Unused Slot Maintenance: Keep dust caps installed over any unpopulated SFP slots to preserve internal optical receiver cleanliness.
