HP J4899C Hewlett-Packard HP ProCurve networking / enterprise server hardware Datacentre Switch

The HP J4899C is a ProCurve Switch 2650, a managed Layer 2 switch with 48 auto-sensing 10/100 ports plus 2 dual-personality Gigabit ports for either copper or mini-GBIC fibre uplinks. It supports VLANs, spanning tree and other standard enterprise switching features, and its high port density makes it a common choice for wiring-closet aggregation in mid-sized office and campus networks. As a fixed-configuration switch rather than a chassis blade, it operates standalone rather than as part of a larger platform, though it is often deployed alongside other 2600-series switches under common management. This unit is the correct replacement for a failed or end-of-life 2650 already in service. Specifiers should confirm their firmware version and VLAN configuration requirements before ordering. Tech-Star (UK-based, shipped worldwide) sources and tests refurbished HP parts like this one to keep 2600-series deployments running past end of manufacturer support.
