HP JD218A Hewlett-Packard HP ProCurve networking / enterprise server hardware Power Supply

The HP JD218A is an HP A7500 1400W AC power supply, a hot-swappable field-replaceable unit for the HP A7500 modular chassis switch series. It supplies DC power to the switch backplane and, where fitted alongside a second unit, provides N+1 power redundancy so the chassis keeps running if one supply fails. The A7500 platform (later continued under H3C and HPE Networking branding) is a core/aggregation switch used in campus and data-centre networks, and this power supply is the correct spare for maintaining full capacity or restoring redundancy after a failure. Specifiers should confirm their chassis variant and power budget before ordering, since A7500 chassis are available in several slot counts with different power requirements. Tech-Star (UK-based, shipped worldwide) supplies refurbished HP hardware for engineers maintaining or expanding existing A7500 deployments.
