6. Installation Method

DIN-Rail Mounting: Hook the top groove of the rear bracket onto the top edge of the 35mm DIN rail, then push the lower part of the unit inward until the locking spring clicks firmly into place.

Grounding: Connect a dedicated earth conductor to the functional grounding screw located on the device chassis before applying power.

Power Wiring: Strip the 12/24/48V DC power wires and secure them into the removable screw-terminal block (V1+, V1-, V2+, V2-). Ensure proper SELV/PELV compliance.

Data Cables: Connect RJ45 Ethernet cables for copper ports (10/100Base-TX) and singlemode SC optical fiber cables to the FX fiber uplinks.

7. Operating Instructions

First-Time Boot: Apply supply voltage. Watch the front panel LED indicators:

P1 / P2 (Power): Solid Green indicates healthy primary/secondary power inputs.

FAULT: Red if a power line fails or a configured port drops its link.

STAT: Green indicates normal system operation.

Default IP Address Assignment: Connect via serial terminal console (115200 baud, 8N1) or use the Hirschmann HiDiscovery tool over LAN to detect the switch MAC address and assign an IP address.

Web GUI Login: Open a web browser, enter the assigned IP address, and log in with default credentials (admin / private or as initialized).

Maintenance & Reset: Utilize the DIP switches on the unit to set hardware-level ring parameters or trigger a factory default reset if necessary. Ensure clear air gap surrounding top and bottom ventilation slots ($\ge 10\text{ cm}$)
