HPE Aruba X391 550W AC 80 Plus Platinum Power-to-Port Power Supply — JL712A

The HPE JL712A is a 550-watt AC 80 Plus Platinum power-to-port power supply for HPE Aruba X391-compatible switches. The power-to-port airflow direction ensures hot exhaust exits toward the network cable side, aligning with front-to-back (port-side exhaust) data center cooling architectures. 80 Plus Platinum efficiency minimizes power losses for energy-optimized data center switching deployments.

Frequently Asked Questions

What is power-to-port airflow and when should I use it?

Power-to-port (front-to-back) airflow draws cool air in from the power supply side and exhausts hot air out the port/cable side. Use this PSU in data centers with hot-aisle/cold-aisle layouts where network cables face the cold aisle — hot air exhausts into the hot aisle. Mixing airflow directions in the same rack degrades cooling efficiency.

What is the difference between JL712A and port-to-power variants?

JL712A is power-to-port (front-to-back exhaust). Port-to-power (back-to-front) variants exhaust toward the power supply side. Always match PSU airflow direction to your rack's cooling architecture — mixing directions reduces cooling effectiveness and may cause thermal issues.

Is JL712A compatible with all Aruba X391 switch models?

JL712A is designed for Aruba X391 PSU-compatible switches. Not all Aruba switches use the X391 PSU form factor. Consult the Aruba QuickSpecs for your specific switch model to confirm JL712A compatibility and wattage requirements.
