HP J9028B Hewlett-Packard HP ProCurve networking / enterprise server hardware Datacentre Switch

The HP J9028B is a ProCurve 1800-24G, an unmanaged Gigabit Ethernet switch from HP’s ProCurve small-business range built for plug-and-play desktop and workgroup deployments needing no configuration. It combines fixed-speed autosensing 10/100/1000 ports with automatic MDI/MDI-X crossover detection and IEEE 802.3x flow control, giving small offices and branch sites full-duplex gigabit connectivity without the licensing or management overhead of a managed switch. The 1800 series sits below HP’s managed 2500/2600 lines in the ProCurve stack, aimed at users who want gigabit speed with zero setup. As with all ProCurve products of this generation, buyers of used units should confirm current support status independently rather than assume original warranty terms still apply. Tech-Star (UK-based, shipped worldwide) supplies ProCurve 1800-series switches to keep existing small-office network installations running.
