Switch HP 2920-24G-POE+, model J9727A, Gigabit, complet, functional, pret fix.

J9727A | The HP 2920 Switch Series consists of five switches: HP 2920-24G and 2920-24G-PoE+ with 24 10/100/1000 ports and HP 2920-48G, 2920-48G-PoE+ and 2920-48G 740W PoE+ with 48 10/100/1000 ports. Each switch is equipped with four dual-personality ports for 10/100/1000 or SFP connections. In addition, the 2920 Switch Series supports up to four optional 10 Gigabit Ethernet ports (SFP+ and/or 10GBASE-T) and a two-port stacking module. These options provide flexible and easy-to-implement uplinks and stacking. Static and RIP routing, robust security and management options, enterprise-class features, a lifetime free warranty and free software upgrades make the HP 2920 Switch Series a cost-effective and scalable solution for customers deploying high-performance networks. These switches can be deployed at the enterprise perimeter, in branch offices and in converged networks.
