Product Overview

The C2RPS‑PSM (STK‑RPS‑150PS) is a hot‑swappable redundant power supply module for Enterasys SecureStack C2 series industrial Ethernet switch chassis. It provides stable 12 V DC 150‑watt backup power for network switching hardware, delivering seamless hitless power fail‑over when the primary internal power supply fails.

This AC‑to‑DC power unit adopts high‑efficiency power conversion circuit design. Multiple built‑in protection mechanisms prevent damage from short‑circuit, overload and over‑temperature conditions. Hot‑swap design permits module removal and replacement while the connected switch remains fully operational. Front‑panel LED gives visual status feedback for rapid on‑site troubleshooting. The STK‑RPS‑150PS is the external RPS power unit, and C2RPS‑PSM is the internal power‑supply module for C2RPS‑CHAS8 chassis. Original OEM production discontinued; widely available as surplus / refurbished spare parts for legacy industrial network infrastructure maintenance.

Application Notes

• Compatible with Enterasys SecureStack C2 series switch chassis and C2RPS‑CHAS8 redundant power shelf.
• Supports parallel redundant deployment; multiple modules can work in load‑sharing mode for high‑availability network setup.
• Hot‑swap function works only when chassis remains powered; observe anti‑static precautions during handling.
• Install inside standard industrial cabinet; maintain proper ventilation airflow to avoid over‑heating.
• Avoid condensation, dust accumulation and corrosive gas exposure.
• Verify hardware compatibility before installation, follow Enterasys official hardware installation manual.
• Typical deployment: factory automation control networks, DCS plant network cabinets, enterprise critical‑link network retrofits and spare‑part maintenance.
