Extreme Networks 45012 Summit 300W AC Power Supply Unit

The Extreme Networks 45012 is a high-reliability 300W AC Power Supply Unit (PSU) designed specifically for the Summit series of network switches, including the X440 and X460 families. This internal power module provides the primary DC voltage required to support the switch’s internal logic, port interfaces, and cooling assemblies. It is engineered with a wide-range AC input (100–240V), ensuring operational flexibility across various global regional power standards. The 45012 is designed to meet high energy efficiency standards, minimizing thermal output and reducing the overall power consumption of the networking equipment.This PSU features a hot-swappable architecture, allowing for field replacement or the addition of a secondary unit for N+1 redundancy without requiring a system reboot or causing service interruption. The integrated intelligent monitoring circuitry communicates with the ExtremeXOS operating system, providing real-time telemetry on power status, input voltage, and internal thermal conditions. For safety and hardware longevity, the unit incorporates comprehensive protection mechanisms, including over-voltage (OVP), over-current (OCP), and short-circuit protection (SCP), which safeguard the switch’s sensitive electronic components from electrical anomalies.
Constructed for enterprise-class reliability, the 45012 includes an integrated cooling fan that works in synchronization with the switch’s airflow management system to ensure stable operation under high-load conditions. The robust mechanical design features a secure locking mechanism to prevent accidental disconnection and high-quality electrical contacts to minimize impedance. It is fully compliant with international safety and electromagnetic compatibility (EMC) standards, making it a critical component for maintaining the high availability and performance required in mission-critical data centers and campus network environments.
