- Features

 

+ 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 demands.
  • Increase performance with selectable queue configurations and associated memory buffering that meet your network application requirements.
  • With up to 740 W 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 80 PLUS 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 (QoS)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, and MAC and Web for greater, policy-driven application security.
  • 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.
