HPE 2920-48G Switch - Switch - L3 - managed - 44 Product Details

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. Features of the HP 2920-48G Switch
  • Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues
  • Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers
  • Class of Service (CoS): sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ
  • Rate limiting: sets per-port ingress enforced maximums and per-port, per-queue minimums
  • Large buffers: provide graceful congestion management
  • Flexible 10 Gb/s Ethernet connectivity: up to four optional 10-Gigabit ports (SFP+ and/or 10GBASE-T)
  • Two-port stacking module with up to 40 Gb/s per port: optional two-port stacking module allows stacking of up to four switch units into a single virtual device
  • Auto-MDIX: provides automatic adjustments for straight-through or crossover cables on all 10/100 and 10/100/1000 ports
  • IPv6: IPv6 host: allows the switches to be managed and deployed at the edge of IPv6 networks. Dual stack (IPv4/IPv6): provides transition mechanism from IPv4 to IPv6; supports connectivity for both protocols. MLD snooping: forwards IPv6 multicast traffic to the appropriate interface; prevents IPv6 multicast traffic from flooding the network.
  • IEEE 802.3at Power over Ethernet (PoE+): provides up to 30 W per port that allows support of the latest PoE+-capable devices such as IP phones, wireless access points, and security cameras, as well as any IEEE 802.3af-compliant end device; eliminates the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments
  • 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.
  • HP ProVision ASIC architecture: is designed with the latest HP ProVision ASIC, providing very low latency, increased packet buffering, and adaptive power consumption
  • Selectable queue configurations: allows for increased performance by selecting the number of queues and associated memory buffering that best meet the requirements of the network applications
  • OpenFlow: is a key technology that enables software-defined networking by allowing the separation of data (packet forwarding) and control (routing decision) paths
  • IP multicast snooping and data-driven IGMP: automatically prevent flooding of IP multicast traffic
  • IEEE 802.1AB Link Layer Discovery Protocol (LLDP): facilitates easy mapping using network management applications with LLDP automated device discovery protocol
  • LLDP-MED (Media Endpoint Discovery): defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure network devices such as IP phones
  • PoE and PoE+ allocations: support multiple methods (automatic, IEEE 802.3at dynamic, LLDP-MED fine grain, IEEE 802.3af device class, or user specified) to allocate and manage PoE/PoE+ power for more efficient energy savings
