The JPSU-650W-DC-AFI is a 650-watt DC power supply module designed for Juniper networking platforms, featuring front-replaceable unit (FRU) installation and side-to-side airflow from the FRU side to the port side.
It delivers 650 W of DC power, supports –40 V to –72 V input, operates at 90%+ efficiency, and provides side-to-side airflow cooling to maintain optimal thermal performance.
This power supply is compatible with select Juniper EX and QFX Series switches equipped with DC power supply bays that accept FRU modules with side-to-side airflow.
FRU side-to-port side airflow indicates that cooling air enters through the replaceable power supply side (FRU side) and exits toward the switch port side, ensuring consistent chassis ventilation.
