HIRSCHMANN RS20-0400M2T1SDAPHC08.0.01 Managed Switch

HIRSCHMANN RS20-0400M2T1SDAPHC08.0.01 Managed Switch

The Hirschmann RS20-0400M2T1SDAPHC08.0.01 is an industrial-grade, fully managed Fast Ethernet switch from the classic OpenRail RS20 series. It features a compact, hardened housing optimized for space-saving DIN rail cabinet setups.

With its tailored port configuration consisting of both copper RJ45 interfaces and a multimode fiber-optic uplink, this switch is designed to bridge field devices over extended distances without risking signal degradation from electromagnetic interference (EMI).

Technical Table

Below are the exact technical specifications mapped to the configuration code RS20-0400M2T1SDAPHC08.0.01:

Environmental Tolerance Conditions

Built for heavy-duty industrial environments, the RS20 switch functions reliably under extreme field conditions:

Operating Temperature Range: Standard operating temperature from 0 °C to +60 °C.

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

Vibration Resistance: Evaluated to IEC 60068-2-6 guidelines (exhibiting stability at 1 mm amplitude, 2 Hz to 13.2 Hz).

Mechanical Shock Resistance: Evaluated to IEC 60068-2-27 guidelines (15 g, 11 ms duration).

EMC Immunity: Certified against electrostatic discharge (EN 61000-4-2) and electromagnetic field interference (EN 61000-4-3).

Storage Conditions

To preserve the internal electrical layers, capacitor life, and port contacts of your spare modules prior to deployment, adhere to these storage constraints:

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

Surrounding Atmosphere: Clean, dry, and dust-free. Corrosive gases (such as sulfur or chlorine) must be avoided to prevent micro-corrosion of copper contacts and fiber ferrules.

Maximum Storage Humidity: Less than 95% relative humidity (non-condensing).

Operating Instructions & Commissioning

1. Power and Ground Setup

Connect your redundant DC power sources to the 6-pin terminal block situated at the top of the switch housing. Connect a heavy-gauge copper wire to the grounding screw located at the bottom-right corner of the front metal faceplate to discharge transient voltages.

2. Physical Connections

Insert your standard RJ45 Ethernet patch cables (Cat5e or better) into the copper ports.

Uncap the SC fiber-optic port and connect your multimode duplex fiber cable. Ensure the TX (transmit) and RX (receive) paths are appropriately crossed between nodes.

3. IP Assignment & Diagnostics

The switch does not contain a default IP address out-of-the-box. Run the Hirschmann HiDiscovery utility on your connected computer to scan the local network broadcast domain, locate the switch via its hardware MAC address, and assign your subnet's designated static IP address.

Fault Diagnosis (LED Matrix)

The front panel of the switch features a distinct set of LED indicators designed for rapid troubleshooting inside the control cabinet:
