Nätaggregat Juniper JPSU-350-AC-AFO

The Juniper JPSU-350-AC-AFO is an AC field-replaceable power supply unit for Juniper EX4300 series switches. It provides up to 350 W of total power, accepts an AC input voltage range of 100–240 V at 50–60 Hz, and is designed for hot-insertable and hot-removable installation to avoid powering down the switch or interrupting switching functions. Some EX4300 models are shipped with one AC power supply pre-installed; certain models require the power supply to be ordered separately.

Advantages

The unit supports hot-swap installation and removal, enabling replacement without disrupting network operation. It delivers a 350 W power capacity with universal AC input (100–240 V, 50–60 Hz) for flexible deployment in different power environments. The compact design and compatibility with EX4300 switches simplify inventory and maintenance.

How to use

Install the JPSU-350-AC-AFO into the rear power bay of a compatible EX4300 switch.
