The ENTERASYS STK-RPS-150PS P0973BP is a high-availability redundant power supply engineered for Enterasys (Extreme Networks) networking switches, delivering uninterrupted power for mission-critical network operations. Designed as a hot-swappable external RPS module, it provides 150W of backup power with dual AC inputs (100–240 VAC) and automatic failover to safeguard switches during main PSU failures. Compatible with Enterasys A-Series, C-Series, and K-Series switches, the ENTERASYS STK-RPS-150PS features intelligent load sharing, real-time health monitoring, and audible/visual fault alerts to prevent downtime in industrial, enterprise, and data center environments. Its rugged metal housing supports desktop or rack mounting (1U), while wide-temperature operation (-10°C to +50°C) ensures reliability in controlled industrial settings.

Installation and Maintenance
Pre-installation preparation: Verify switch compatibility and firmware version. Ensure AC sources are separate circuits. Ground chassis via provided terminal (≤0.1 Ω resistance). Position ≤1m from protected switch using included cable.
Maintenance recommendations: Test failover quarterly by disconnecting primary PSU. Clean ventilation slots annually with compressed air. Monitor SNMP traps for voltage deviations. Replace after 7 years or 60,000 operational hours.
