HP J4834A Hewlett-Packard HP ProCurve networking / enterprise server hardware Optical Transmission Module

The HP J4834A is a ProCurve 100/1000Base-T transceiver, an auto-sensing copper transceiver module for GL and XL-series chassis switches that negotiates either Fast Ethernet or Gigabit Ethernet speed over standard copper cabling, depending on what the connected device supports. It fits the mini-GBIC or equivalent transceiver slots on compatible ProCurve chassis modules, giving flexibility to run a copper link at whichever speed the far end needs without swapping hardware. This is the correct spare for restoring a failed copper transceiver port or for adding auto-sensing copper connectivity to an existing chassis module with an open transceiver slot. Specifiers should confirm which chassis and module generation this transceiver is compatible with before ordering. Tech-Star (UK-based, shipped worldwide) supplies refurbished HP hardware for engineers maintaining or expanding existing ProCurve chassis deployments.
