350W AC power supply for EX4300

The Juniper Networks JPSU-350-AC-AFI is a 350 watt AC power supply designed for the EX4300 switch platform. It delivers back-to-front airflow to match the cooling path of compatible network hardware. Network engineers and data-centre operators use it to power or replace a supply in an EX4300 chassis. The unit is sold new and ready for installation.

Back-to-front airflow replacement for EX4300

This supply replaces a failed or missing 350W AC unit in an EX4300 switch when the chassis requires back-to-front airflow. The upgrade is worth it when the existing power supply has reached end of life or when a redundant slot must be populated for high-availability operation. It is not suitable for switches that require front-to-back airflow or for platforms outside the EX4300 series.

Questions about this item

What switch chassis does the 350 W power supply fit?

The unit is built for the EX4300 series and slides directly into its power-supply bay.

Which way must the module face for correct back-to-front airflow?

Insert it so the fan pulls cool air from the rear of the rack and exhausts it toward the front panel.
