JUNIPER EX-PWR3-930-AC Networks EX-series Ethernet switch power supply family Power Supply

The Juniper EX-PWR3-930-AC is a 930W AC power supply unit for the Juniper Networks EX-series Ethernet switch family, providing the primary or redundant power feed for supported EX switch chassis. As with other EX-series PSU modules, it is a field-replaceable, hot-swappable unit designed to slot directly into the switch chassis power bay, letting operators maintain N+1 redundancy or replace a failed supply without powering down the switch. EX-series switches are Juniper’s standard access and aggregation-layer Ethernet switch line, deployed across enterprise and campus networks, and PSU modules such as this are a standard spares item for maintaining uptime on existing EX deployments. Tech-Star (UK-based, shipped worldwide) supplies tested Juniper EX-series power supplies; contact our engineers to confirm compatibility with your specific switch model before ordering.
