HP J4122A Hewlett-Packard HP ProCurve networking / enterprise server hardware Datacentre Switch

The HP J4122A is a ProCurve Switch 2400M, a modular chassis switch supplied here with a fixed J4111A 10/100Base-T module already installed, giving an initial set of copper access ports out of the box while retaining expansion slots for additional modules such as fibre uplinks or further copper ports. The 2400M chassis is an entry-level modular platform from this ProCurve generation, aimed at smaller deployments that still want the flexibility of adding modules later rather than committing to a fixed-configuration switch. This unit is the correct replacement for a failed or end-of-life 2400M chassis already in service, or for building out a new small modular deployment. Specifiers should confirm what additional modules are needed for their port count before ordering. Tech-Star (UK-based, shipped worldwide) supplies refurbished HP hardware for engineers maintaining or expanding existing 2400M deployments.
