Product Details

The Juniper JPSU-920-AC-AFO is a high performance 920 Watt AC power supply unit designed specifically for the Juniper EX Series Ethernet Switches, including the EX3400 and EX4100 models. This field replaceable unit ensures reliable power delivery for mission critical network environments, particularly those requiring higher power budgets for Power over Ethernet applications. The unit features Front to Back airflow, also known as Airflow Out, which intakes cool air from the port side and exhausts hot air through the power supply vents. This airflow direction is critical for maintaining proper thermal management in hot aisle and cold aisle data center configurations. Engineered for redundancy and uptime, this module supports hot swapping, allowing IT administrators to replace or upgrade power supplies without disrupting network traffic or powering down the switch.
