Extreme Network Inc XN-ACPWR-550W-FB-A – Power Supply Module

Overview :

The Extreme Networks XN-ACPWR-550W-FB-A is a 550W AC hot-swap power supply module designed for enterprise network switching platforms. It is deployed in compatible Extreme Networks chassis-based switches where redundant or failed PSU replacement is required without service interruption.

This unit delivers 550W of regulated AC output power with front-to-back airflow architecture to align with high-density data center cooling patterns. It is typically used in aggregation switches and campus/core network deployments requiring redundant power design.

It is not a general-purpose ATX PSU and must only be installed in supported Extreme Networks systems (notably 5520 series platforms). It is incompatible with standard PC/server power systems.

Primary use cases include redundant power provisioning, field replacement of failed PSU modules, and high-availability switch deployments in enterprise and carrier-grade environments.

Key Features :

• 550W hot-swappable AC power module for network switches
• Front-to-back airflow supports data center cooling design
• Designed for redundant power in Extreme 5520 platforms
• Supports uninterrupted replacement in live environments
• Enterprise-grade PSU for mission-critical switching systems
