Product Information

Full Description

Details

The HP 2920 Switch Series provides security, scalability and ease of use for enterprise edge, SMB and branch office access layer deployments. A powerful HP Networking ASIC delivers low latency, more packet buffering, and adaptive power consumption to this robust Basic Layer 3 switch that supports modular stacking, 10GbE, RIP routing, PoE+, ACLs, sFlow and IPv6. The HP 2920 Switch Series can be managed with the optional HP Intelligent Management Center (IMC) software for a single view of your entire network and is ready for the Software-defined Network (SDN) with OpenFlow support.

  • Flexible, Scalable and SDN Ready Access Layer Switches
  • High Performance and Power at the Edge
  • Security and Quality of Service You Can Rely On
  • Simplify with a Single View of the Network
  • Convergence
  • Resiliency and high availability

  • Flexible, Scalable and SDN Ready Access Layer Switches
    The HP 2920 Switch Series provides security, scalability and ease of use for enterprise edge, SMB and branch office access layer deployments. Cost-effective pay as you grow modular stacking, support for up to four 10GBASE-T (or SFP+) links and upgradeable power supplies allow your network to quickly scale when needed. Robust Basic Layer 3 feature set includes static and RIP routing, PoE+, ACLs, sFlow, IPv6 and requires no software licensing. Software-defined Network (SDN) enabled with OpenFlow support for your network.
  • High Performance and Power at the Edge
    The HP 2920 Switch Series is designed with a powerful HP Networking ASIC, providing low latency, increased packet buffering, and adaptive power consumption so the network can support the media-rich, bandwidth intensive applications your business depends on. Increase performance with selectable queue configurations and associated memory buffering that meets your network application requirements. With up to 740W of internal PoE+ power, the 2920 Switch Series can easily scale to 1440 Watts with a simple connection to an external power supply (EPS) or redundant power supply (RPS). Plug and play stacking with automated failover enhances network resiliency and RPS support delivers power redundancy. Efficient 80plus.org Silver Grade Power Supplies, Energy Efficient Ethernet and LLDP-MED conserve energy resources. Removable power supplies reduce downtime during upgrades and servicing.
  • Security and Quality of Service You Can Rely On
    The HP 2920 Switch Series includes security and quality of services features to build a network that meets ever-changing corporate policies and compliances and help protect your data from both inside and outside attacks. Flexible authentication options include standards based security protocols such as 802.1X, MAC and Web Authentication, to enhance security and policy-driven application authentication. Powerful multilevel-access security controls include source-port filtering, RADIUS/TACACS+, SSL, Port Security, and MAC address lockout.
  • Simplify with a Single View of the Network
    The HP 2920 Switch Series can be seamlessly managed with the optional HP Intelligent Management Center (IMC) Software to provide end-to-end network transparency with a consistent network experience through comprehensive configuration, compliance and policy management. RMON and sFlow provide advanced monitoring and reporting capabilities for statistics, history, alarms and events. Out-of-band Ethernet management port keeps management traffic segmented from your network data traffic.
  • Convergence
    IP multicast snooping and data-driven IGMP: automatically prevent flooding of IP multicast traffic. 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. IEEE 802.1AB Link Layer Discovery Protocol (LLDP): facilitates easy mapping using network management applications with LLDP automated device discovery protocol. 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.
  • Resiliency and 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 and IEEE 802.1w. IEEE 802.3ad Link Aggregation Control Protocol (LACP) and HP port trunking: support up to 60 static, dynamic, or distributed trunks active across a stack, with each trunk having up to eight links (ports) per static trunk; support trunking across stack members. Ring and chain stacking topology: allows failure of a link or switch in the ring of stacked switches, while the remaining connected switches continue operation.
  • Management
    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. Out-of-band Ethernet management port: enables management over a separate physical management network, keeping management traffic segmented from network data traffic.

Ask a Question


  • Is your stock grey or sourced outside of approved channels?

    Categorically no! All our  stock is ethically sourced within the EU and backed by warranty. Hewlett Packard products sold as new are retail sealed units covered by the full manufacturer warranty. For added peace of mind, we can supply serial numbers up front which you can validate online to confirm warranty cover ahead of purchase.

  • How are your prices so low?

    At King of Servers we conduct regular price checks to maintain an up to date view on our pricing in relation to our online competitors. We aim to ensure our products are always priced as keenly as possible across our entire catalogue.

    Since it’s impossible to keep tabs on everyone, we offer a Price Match Challenge . If you find a better price elsewhere, we'll do our very best to match it.

    We're not as big as some of our competitors so we have to try harder to win your business and this means offering better prices and better service levels. We’re also fortunate to have smaller overheads than some of our larger competitors and this, coupled with our buying power allows us to secure volume related discounts from our established global network of suppliers. These savings are ultimately reflected in the prices of our products.

    Cheaper doesn't always mean better though, read our blog and watch out for the common pitfalls
