Overview The HP 2920 Switch Series consists of five switches: the HP 2920-24G & 2920-24G-Po E+ Switches with 24 10/100/1000 ports, & the HP 2920-48G & 2920-48G-Po E+ & 2920-48G 740W Po E+ Switches with 48 10/100/1000 ports. 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 & easy-to-deploy uplinks & stacking. Together with static & RIP routing, robust security & management, enterprise-class features, free lifetime warranty, & 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, & in converged networks. Features Quality of Service (Qo S) • Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues Connectivity • Flexible 10 Gbps Ethernet connectivity: up to four optional 10-Gigabit ports (SFP+ and/or 10GBASE-T) Performance • Energy-efficient design: High-efficiency power supplies: 80 PLUS Silver Certified power supply increases power savings. Energy-efficient Ethernet (EEE) support: reduces power consumption in accordance with IEEE 802.3az. Software-defined networking • Open Flow: is a key technology that enables software-defined networking by allowing the separation of data (packet forwarding) & control (routing decision) paths Convergence • IP multicast snooping & data-driven IGMP: automatically prevent flooding of IP multicast traffic Resiliency & high availability • IEEE 802.1s Multiple Spanning Tree: provides high link availability in multiple VLAN environments by allowing multiple spanning trees; provides legacy support for IEEE 802.1d & IEEE 802.1w Management • SNMPv 1, v 2, & v 3: provides complete support of SNMP; provide full support of industry-standard Management Information Base (MIB) plus private extensions; SNMPv 3 supports increased security using encryption
