Each switch has four dual-personality ports for 10/100/1000 or SFP connectivity. In addition, the 2920 switch series supports up to four optional 10 Gigabit Ethernet (SFP+ and/or 10GBASE-T) ports, as well as a two-port stacking module. These options provide you with flexible and easy-to-deploy uplinks and stacking. Together with static and RIP routing, robust security and management, enterprise-class features, free lifetime warranty, and free software updates, the HP 2920 Switch Series is a cost-effective, scalable solution for customers who are building high-performance networks. These switches can be deployed at the enterprise edge, in remote branch offices, and in converged networks.<br /><br /><b>Quality of Service (QoS)</b><br />\n&bull;&nbsp;Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues<br /><br />\n<b>Connectivity</b><br />\n&bull;&nbsp;Flexible 10 Gb/s Ethernet connectivity: up to four optional 10-Gigabit ports (SFP+ and/or 10GBASE-T)<br /><br />\n<b>Performance</b><br />\n&bull;&nbsp;Energy-efficient design: High-efficiency power supplies: 80 PLUS Silver Certified power supply increases power savings.
