HIRSCHMANN m4-8TP-RJ45 Ethernet Media Module

Product Overview

The Hirschmann M4-8TP-RJ45 (Part Number: 943 863-001) is an 8-port Gigabit Ethernet media module designed for the MACH4000 series of high-density modular backbone switches.

 It expands copper connectivity inside industrial control rooms, substations, and enterprise backbones by offering high-bandwidth Gigabit Ethernet connections over standard twisted-pair cables.

Technical Parameter List

Key Features & Advantages

High-Density Gigabit Connectivity: Offers 8 Gigabit copper ports in a single module slot to reduce rack footprint.

Hot-Swappable Design: Can be installed or replaced without shutting down the host MACH4000 switch chassis, ensuring zero downtime for non-affected network links.

Auto-Sensing Intelligence: Features Auto-MDI/MDI-X (auto-crossing) and auto-negotiation, eliminating the need for crossover cables.

Low Power Consumption: Operates efficiently drawing only ~2 W directly from the backplane.

Comprehensive LED Diagnostics: Provides per-port status LEDs for quick visual troubleshooting on the panel.

Model Classification & Module Variants

Environmental Tolerance Conditions

Installation Method

Prerequisite: Ensure static safety precautions (ESD grounding wrist strap) are followed before handling network modules.

Locate Slot: Identify an open media module slot on the front of the Hirschmann MACH4000 chassis.

Align Rails: Line up the module circuit board edges with the guide rails inside the slot.

Insert Module: Slide the module firmly into the slot until the backplane connector locks in place.

Secure Fasteners: Tighten the captive mounting thumb screws on both sides of the module front panel to ensure solid grounding and mechanical connection.

Connect Cables: Plug standard RJ45 Cat5e/Cat6 Ethernet cables into the 8 ports.

Operating Instructions

Power-On Verification: Once inserted into an active MACH4000 chassis, check that the Module Power LED turns solid green.

Link Status Checking: Observe the LED indicators above each RJ45 port:

Link/Data LED: Solid green indicates an active link; blinking green indicates data traffic.

Duplex/Speed LED: Displays line rate (10/100/1000 Mbps) and full-duplex operation status.

Software Configuration: Access the MACH4000 Switch Management Web Interface or CLI via console/SSH. 

The newly inserted module will automatically register in the port overview, allowing VLAN assignment, port mirroring, or bandwidth throttling.
