HP J4138A Hewlett-Packard HP ProCurve networking / enterprise server hardware Datacentre Switch

The HP J4138A is a ProCurve Routing Switch 9308M, an 8-slot chassis-based switching router from HP’s 9300m series delivering up to 100 million packets per second across as many as 64 Gigabit Ethernet ports or up to 184 autosensing 10/100 ports depending on the line cards installed, supplied here with one AC power supply fitted. The 9300m series combines Layer 2 switching with hardware-based Layer 3/4 routing (including IP, IPX and AppleTalk routing plus IGMP/DVMRP/PIM multicast) on a single chassis, positioning it as a backbone or core-routing platform for larger enterprise and campus networks rather than an access-layer switch. As a modular chassis, its actual capacity depends entirely on which line cards are fitted; the chassis alone provides slots, backplane and the single PSU listed, with modules ordered separately. Buyers should confirm exact module and firmware compatibility for their specific 9300m deployment before ordering. Tech-Star (UK-based, shipped worldwide) supplies ProCurve 9300m-series chassis routers for ongoing core-network maintenance.
