HP E2520 Switch Series

Overview:

The HP E2520 Switch Series is ideally suited for small and medium businesses looking to deploy voice, video, or wireless solutions that require Power over Ethernet (PoE) connectivity. The series consists of four switches: the HP E2520-8-PoE, the HP E2520-24-PoE, the HP E2520-8G-PoE, and the HP E2520-24G-PoE Switch. The four models offer a choice of either Fast Ethernet or Gigabit Ethernet connectivity. All models also include support for dual-personality Gigabit Ethernet ports that can be used for either copper or fiber connectivity. All products are fully managed via SNMP, command-line interface (CLI), and graphical user interface (GUI) and offer a Layer 2 feature set. In addition, the products provide deployment flexibility with compact, quiet, and energy-efficient designs.

• Fully managed Layer 2 switch in 8 or 24 ports
• Choice of Fast Ethernet or Gigabit PoE models
• Power over Ethernet for voice, video, and wireless
• Energy-efficient design and quiet operation
