HP J4862A Hewlett-Packard HP ProCurve networking / enterprise server hardware Switch / Carrier Ethernet Line Card

The HP J4862A is a ProCurve Switch GL 24-port 10/100Base-TX module, a copper expansion card for the Switch 4000M and 8000M “GL” chassis switch family that adds 24 Fast Ethernet ports to an existing GL chassis. It is a modular line card rather than a standalone switch, fitting into an available expansion slot in a GL-series chassis alongside the chassis’s built-in ports and any other installed modules. This is the correct spare for restoring 10/100 port capacity after a module failure or for expanding an existing GL chassis with additional copper ports. Specifiers should confirm chassis slot availability and firmware compatibility before ordering, since GL-series chassis and modules were produced over a long product run with several hardware revisions. Tech-Star (UK-based, shipped worldwide) stocks and tests this as part of its refurbished HP range, for maintenance, redundancy or expansion of GL-series deployments.
