Juniper EX3400 600 W AC PSU Front-to-Back | Rack Mount Enterprise

Keep EX3400 switching infrastructure powered with a 600 W AC power supply designed for the demands of dense enterprise racks. Front-to-back airflow aligns with common data center cooling paths, helping preserve thermal consistency across adjacent equipment and reducing the risk of hot-spot buildup in tightly packed closets. This PSU is built for the Juniper EX3400 family, making it a practical fit for teams that need a direct replacement path rather than a generic alternative. The 600 W output supports the power profile expected in access-layer deployments where uptime, serviceability, and predictable integration matter more than low-cost substitutions. For infrastructure teams, the value is in operational continuity. Matching the airflow direction to the chassis design helps avoid unnecessary thermal conflicts, while the AC supply format supports standard rack power distribution. When a power module needs to be swapped, a platform-specific unit reduces guesswork and shortens maintenance windows. Choose this PSU when the cost of downtime outweighs the savings of an off-platform part. It is the right fit for organizations that want stable power delivery, cleaner thermal behavior, and a replacement component aligned to the EX3400 hardware stack.
