Hirschmann RS20-1600M2M2SDAPHC08.0.05 Industrial Managed Switch

The Hirschmann RS20-1600M2M2SDAPHC08.0.05 (Belden Part Number: 943 434-023) is an enterprise-grade, highly resilient 16-port managed Fast Ethernet switch. Part of the legendary OpenRail RS20 family, this switch is designed to form the core of reliable, ruggedized Ethernet networks in harsh industrial automation and critical infrastructure settings.

Product Introduction & Overview

The RS20-1600M2M2SDAPHC08.0.05 is a pre-configured, hardened DIN-rail switch that perfectly balances high port density with fiber-optic backhaul capabilities. Featuring 14 Fast Ethernet copper RJ45 ports and 2 Multi-Mode SC fiber ports, it allows for the high-density connection of local control cabinet equipment while utilizing the fiber links to securely transmit data up to 5 km without electromagnetic interference.

This model runs the robust HiOS/Classic Switch Software (Layer 2 Professional), providing advanced diagnostic, redundancy, and security features tailored specifically for OT (Operational Technology) environments.

Technical Parameter List

Product Features & Core Advantages

Ultimate Network Redundancy: With Hirschmann's proprietary HIPER-Ring and standard MRP protocols, network ring recovery takes less than $20text{ ms}$ in the event of a line break, preventing industrial process downtime.

Granular Security Control: Features MAC-based port security, IEEE 802.1X network access control, guest/unauthenticated VLANs, and HTTPS/SSL encryption to defend industrial machinery from unauthorized access.

Industrial Grade Power Input: Equipped with dual-redundant power terminal blocks to ensure the switch remains online even if one primary power supply line fails.

Easy Module Replacement (ACA21): Features a USB interface matching Hirschmann’s ACA21 Auto-Configuration Adapter. In the rare event of hardware failure, a technician can swap the switch, plug in the ACA21. and the new switch automatically pulls its entire configuration within seconds.

Model Classification (RS20 Code Breakdown)

The Hirschmann OpenRail nomenclature translates to these exact physical hardware configurations:

RS20-16: 16 Ports total capacity.

00: Zero Gigabit Ethernet ports (all ports are 10/100M Fast Ethernet).

M2M2: 2 x Multi-Mode ($1300text{ nm}$ wavelength) SC fiber ports.

S: Standard temperature range ($0^circtext{C}$ to $+60^circtext{C}$).

D: Power supply operating at $12/24/48text{ V DC}$ and $24text{ V AC}$.

A: Standard approvals (CE, FCC, cUL 508).

P: Layer 2 Professional Software (full redundancy, security, and management package).

H: HiOS / Classic software baseline.

08.0.05: Exact operating software version release loaded on production.

Environmental Tolerance Conditions

Built strictly for demanding, non-climate-controlled control rooms and outdoor cabinets:

Operating Temperature: $0^circtext{C}$ to $+60^circtext{C}$ ($32^circtext{F}$ to $140^circtext{F}$).

Storage Temperature: $-40^circtext{C}$ to $+70^circtext{C}$ ($-40^circtext{F}$ to $158^circtext{F}$).

Relative Humidity: 10% to 95% (non-condensing) via conformal-coated structural components.

Protection Class: IP20 rated polycarbonate enclosure resistant to high mechanical vibration and shock (IEC 60068-2 standards).

Installation Method

[DIN Rail Mounting Bracket]

||

/

===|=== <-- Top of DIN Rail Hook

|

[ Switch ]

|

===|=== <-- Bottom Spring-Loaded Clip

Positioning: Hook the upper mounting groove of the switch's rear DIN-rail clip onto the top edge of the 35mm DIN rail.

Snapping Down: Press the bottom front of the switch downward and inward toward the rail. The spring-loaded bottom clip will snap shut onto the rail with a distinct click.

Grounding: Connect the functional ground screw terminal on the bottom-left front panel of the switch housing directly to your cabinet's central ground bar using a low-impedance conductor.

Operating Instructions

1. Powering the Unit

Unscrew the 6-pin terminal block on the top right. Wire the redundant power lines as follows:

$L1+$ and $M1$: Primary power supply ($+$ and $-$).

$L2+$ and $M2$: Backup power supply ($+$ and $-$).

Fault Terminals: Connect these in-series to an external PLC input or warning lamp to monitor power loss or link failure events.

2. Accessing the Configuration Web Interface (GUI)

Out of the box, the switch does not have a default IP. Assign a temporary IP using the Hirschmann HiDiscovery tool or via DHCP.

Open a web browser on a laptop within the same subnet and enter the assigned IP address.

Log in using the default credentials: Username: admin | Password: private (Note: The switch will prompt you to change the password on your first login for security).

3. Ring Redundancy Activation

To set up a highly reliable ring:

Connect the optical fibers to form a physically closed ring between your switches.

Log into the GUI, navigate to Redundancy > Ring Redundancy, and enable MRP or HIPER-Ring on the two optical ports (Ports 1 and 2).

Designate one switch in the ring as the Ring Manager (RM) and all other switches as Clients.
