HP 2920-48G J9728A Switch
SKU: J9728A
The HP 2920 Switch Series consists of five switches: the HP 2920-24G and 2920-24G-PoE+ Switches with 24 10/100/1000 ports, and the HP 2920-48G and 2920-48G-PoE+ and 2920-48G 740W PoE+ 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 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 /><br>• Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues<br /><br /><br><b>Connectivity</b><br /><br>• Flexible 10 Gb/s Ethernet connectivity: up to four optional 10-Gigabit ports (SFP+ and/or 10GBASE-T)<br /><br /><br><b>Performance</b><br /><br>• 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.<br /><br /><br><b>Software-defined networking</b><br /><br>• OpenFlow: is a key technology that enables software-defined networking by allowing the separation of data (packet forwarding) and control (routing decision) paths<br /><br /><br><b>Convergence</b><br /><br>• IP multicast snooping and data-driven IGMP: automatically prevent flooding of IP multicast traffic<br /><br /><br><b>Resiliency and high availability</b><br /><br>• 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 and IEEE 802.1w<br /><br /><br><b>Management</b><br /><br>• SNMPv1, v2, and v3: provides complete support of SNMP; provide full support of industry-standard Management Information Base (MIB) plus private extensions; SNMPv3 supports increased security using encryption<br>
