HIRSCHMANN MS20-0800SAAEHC / MS20-0800SAAEHC0 8-port modular Layer 2 management Ethernet switch

HIRSCHMANN MS20-0800SAAEHC / MS20-0800SAAEHC04.0.01

Product Introduction / Overview

The Hirschmann MS20-0800SAAEHC (Firmware Version: 04.0.01. Part Number: 943 435-001) is an industrial-grade, 8-port modular Layer 2 managed Ethernet switch base unit from the renowned MICE (Modular Industrial Communication Equipment) 20 family by Belden/Hirschmann.

Designed for high flexibility in control cabinets, the MS20 base chassis provides slot capacity for mounting up to two media modules (such as the MM2 or MM3 series), 

supporting a total of 8 Fast Ethernet ports (10/100 Mbps). Running on Hirschmann's Classic Layer 2 Enhanced software suite,

 it offers advanced ring redundancy, network management, and high reliability in demanding automation setups.

Technical Table

Environmental Tolerance Conditions

Operating Temperature: 0°C to +60°C (Standard operational range).

Storage / Transport Temperature: -40°C to +70°C.

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

EMC Immunity: High immunity against electrostatic discharge (ESD) and surge voltages per EN 61000-6-2 and EN 55022 Class A standards.

Mechanical Stability: Certified high resistance against shock (15 g, 11 ms duration) and vibration (IEC 60068-2-6 compliant).

Operating Instructions

Module Assembly: Slide and seat up to two compatible MICE media modules (e.g., MM2-2FXM2/2TX1 or MM3-4TX1) into the MS20 slots and tighten the locking thumb screws prior to mounting.

DIN Rail Mounting: Hook the upper spring-loaded rail catch onto the standard 35 mm DIN rail (EN 50022) and snap the bottom firmly into position.

Power Wiring: Wire primary and redundant 24 V DC supply feeds to the 4-pin plug-in terminal block (+24V / 0V for Power Input 1 and Power Input 2).

Initial Configuration & Management:

Connect a PC via an active Ethernet port on one of the installed modules.

Launch Hirschmann HiDiscovery or use BOOTP/DHCP to detect the device's MAC address and assign a static IP address.

Access the Web-based Interface (HTTP/HTTPS) or CLI (SSH/Telnet), log in, and immediately update the default administrative credentials.

Fault Diagnosis

Hardware LED Status:

Power LEDs (P1/P2): Solid Green = Normal power input; Red/Off = Power loss or voltage out of specification.

System Status (STAT/FAU): Green = System operational; Red = Internal system fault or ring redundancy topology mismatch.

Fault Relay (Relay Contact): Triggers an external physical warning loop if a power failure occurs or a monitored port link goes down.

Software Diagnostic Features:

HiVision Integration: Real-time topology monitoring and status indication through Industrial HiVision software.

Port Mirroring & Diagnostics: Integrated port monitoring, signal contact alerts, and cable status diagnostics.

Syslog Logging: Internal log recording for network events and access alerts.
