HPE JL688A 450W 48V FB DC PSU

Overview

The HPE JL688A is a 450W 48V front-to-back DC power supply unit designed specifically for the HPE 5710 series switches. This PSU provides the necessary power to operate the switch in environments where DC power is standard, such as telecommunications closets or facilities with dedicated DC power infrastructure. Deploying this genuine HPE power supply ensures stable operation and prevents compatibility issues that can arise with third-party power sources.

Compatibility

This power supply unit is engineered for the HPE FlexNetwork 5710 series switches. It is intended as a replacement or expansion power module for models within the 5710 family, ensuring seamless integration and reliable performance. Always verify your specific 5710 switch model's requirements to confirm compatibility.

Installation Notes

Installation requires the switch to be powered down. The JL688A PSU slides into a dedicated power supply bay on the front of the switch. Ensure the power source is stable and correctly wired for 48V DC. The front-to-back airflow design means the PSU exhausts heat towards the front of the rack, which is critical for maintaining proper thermal management within the switch and the surrounding rack environment. Proper airflow is essential to prevent overheating and ensure the longevity of the switch and its components.
