Power supply unit accessory Extreme Networks AC 800W, back-to-front airflow, compatible with 7520 and 7720

Extreme Networks AC 800W power supply unit accessory provides up to 800 watts of AC power in a compact, hot-pluggable module designed for compatible Extreme Networks 7520 and 7720 systems. The unit is engineered for back-to-front airflow to match chassis cooling topology and supports redundant power configurations to maintain continuous switch operation in data center and network rack environments.

Advantages

This power supply accessory supports high-efficiency AC power delivery up to 800 W while preserving the chassis airflow pattern with back-to-front cooling. Hot-pluggable design enables service replacement without system shutdown. The unit is built to meet the form factor and electrical requirements of compatible Extreme Networks switches, allowing straightforward integration and redundancy for improved uptime.

Suitable for

• Replacement or spare power supply for Extreme Networks 7520 switches
• Replacement or spare power supply for Extreme Networks 7720 switches
• Maintaining power redundancy in data center racks and network closets
• Environments requiring back-to-front airflow compatible components

Key specifications

• Maximum output power: up to 800 watts
• Input type: AC mains power
• Airflow direction: back-to-front
• Form factor: hot-pluggable PSU module designed for compatible switch chassis
• Cooling compatibility: optimized for chassis with rear intake/front exhaust when configured for back-to-front cooling
• Intended environment: data center and enterprise network racks

How to use

Install the PSU into the designated power bay of a compatible Extreme Networks 7520 or 7720 chassis following the chassis service manual. Ensure the unit is oriented so that airflow matches the chassis cooling design and lock it in place per the manufacturer’s instructions. Connect the AC mains cable to a properly rated, earthed power source and verify that the system recognizes the new unit and that power redundancy indicators report normal status. For hot-swap replacement, remove the failed module while the switch remains powered if the remaining power supplies provide adequate capacity.

Usage recommendations

Use only compatible power supply modules specified for the 7520 and 7720 platforms. Verify that rack power feeds and PDUs can handle the cumulative load of all installed PSUs, and follow ESD and safety procedures during installation. Maintain proper airflow by avoiding obstructions at the chassis intake and exhaust, and schedule periodic inspections to confirm secure connections and cooling performance.
