RS20-0800S2S2SDAEHC09.1.00 HIRSCHMANN Commutator

Product Overview

The Hirschmann RS20-0800S2S2SDAEHC09.1.00 is an 8-port Managed Industrial Fast Ethernet DIN-Rail Switch from Belden's OpenRail RS20 family.

Configured with 6 × 10/100Base-TX RJ45 copper ports and 2 × 100Base-FX Single-Mode (SM) SC fiber optical uplink ports, it provides reliable long-distance network extensions up to 32.5 km.

This unit runs the Enhanced Layer 2 Classic Software (v9.0), offering advanced redundancy features (HIPER-Ring, MRP, RSTP), port-based security, and industrial automation protocol support (PROFINET / EtherNet/IP).

Technical Specifications Table

Environmental Tolerance Conditions

Storage Conditions

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

Storage Relative Humidity: 10% to 95% maximum (non-condensing environment).

Environment: Store in a clean, dry, dust-free indoor location inside standard static-shielded packaging.

Operating Instructions

DIN-Rail Mounting: Snap the switch onto a standard 35 mm DIN rail (EN 50022). Verify the top metal catch locks firmly into position.

Power Supply Wiring: Wire dual redundant DC power feeds (12–48 V DC) or 24 V AC into the 6-pin removable terminal block. Ground the switch via the chassis grounding screw to ensure EMC protection.

Fiber & Copper Connections:

Connect single-mode fiber optic cables (9/125 $mu$m) with SC connectors to ports 1 and 2.

Connect standard RJ45 Cat5e cables to copper ports 3 through 8.

Initial Configuration:

Connect to the switch using HiDiscovery software over Ethernet, or via serial console using the RJ11 (V.24) port.

Access the embedded Web Interface or Command Line Interface (CLI/Telnet) to assign IP settings, configure ring redundancy (HIPER-Ring / MRP), and set VLAN parameters.

Auto-Configuration via USB: Insert an optional ACA21-USB adapter into the USB port to back up device configuration or enable zero-touch field replacement.

Fault Diagnosis & Diagnostic Tools

Diagnostic LEDs Overview: The front panel status LEDs allow rapid hardware and network fault isolation without network software tools.

Power LED Off: Check input voltage on the terminal block and ensure wires are tight.

Error LED On (Red): Indicates a triggered fault relay event (e.g., power loss on one input feed or link loss on a configured port).

Link/Data LED Off: Check cable integrity, verify speed/duplex settings, and ensure fiber SC connectors are properly keyed (TX to RX crossover).

RM / Ring Port LED BGM: Indicates ring redundancy status. Flashing indicates ring breakdown or reconfiguration event.

Advanced Built-In Diagnostics:

Duplex Mismatch Detection: Automatically flags speed/duplex conflicts on connected devices.

Address Conflict Detection: Reports duplicate IP address assignments across the network segment.

Signal Contact (Fault Relay): Built-in potential-free dry contact triggers external alarms/PLC inputs during power or link failure.

Syslog & RMON Logging: Captures network statistics, event logs, and SNMP traps.
