Power Supply 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. Because the unit is hot-insertable and hot-removable, it can be installed or replaced while the switch remains powered and operational. Verify compatibility with the specific EX4300 model before installation and ensure proper seating and secure connection of the power unit.

Recommendations

For models that are not shipped with a pre-installed AC power supply, order the JPSU-350-AC-AFO separately. When replacing a power supply in a live system, follow your site safety procedures and Juniper guidelines to avoid electrical hazards and ensure continuous operation.
