+ 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.
