📦 Description

The PWR-500-DC-F is a 500W hot-swappable DC power supply designed for Arista Networks switches operating in front-to-back cooled environments. With forward airflow, it’s purpose-built for data centers and telecom installations requiring directional thermal management.

This PSU accepts -40V to -72V DC input, making it a natural fit for carrier-grade and infrastructure-grade deployments where DC power systems are standard. It provides a steady 500 watts of clean power to ensure switch stability and uninterrupted network performance.

Designed as a modular internal unit, it installs tool-free into compatible Arista systems and supports hot-swapping, allowing replacement without service disruption. Its forward airflow ensures that thermal profiles remain optimized for systems with front-to-back cooling layouts, which are common in structured enterprise racks.

Safety and stability are assured through integrated protection circuitry, shielding your infrastructure from over-voltage and current faults. Additionally, this unit supports live monitoring and diagnostic feedback, ensuring visibility for IT administrators managing critical environments.

Whether you’re upgrading network resilience or standardizing your DC-powered Arista deployment, the PWR-500-DC-F provides the power density, reliability, and airflow compliance needed for modern high-efficiency networks.
