Energy-efficient design and quiet operation
Rack-mountable and compact form factors
Introduction
The HP 2520 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 three switches: the HP 2520-8-PoE, 2520-24-PoE, and 2520-8GPoE Switches. The three 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.

Power and fault LEDs
: display any issues
Connectivity
Auto-MDIX

IEEE 802.3af Power over Ethernet
: provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP
phones, wireless access points, and security cameras (see product specifications for total PoE power available); supports some
prestandard PoE devices (see product FAQs for more details)
RJ-45 serial console port
: front of unit location provides easy access to the switch CLI
Performance
Switch on a chip
: provides highly integrated, high-performance switch design with a non-blocking architecture
Jumbo packet support
: supports up to 9216-byte frame size to improve performance of large data transfers (2520G switch)

Trunking: supports up to eight links per trunk to increase bandwidth and create redundant connections
IEEE 802.3ad Link Aggregation Protocol (LACP): eases configuration of trunks through automatic configuration
IEEE 802.1s Multiple Spanning Tree Protocol
(MSTP): provides high link availability in multiple VLAN environments by allowing
multiple spanning trees; provides legacy support for IEEE 802.1w (Rapid Reconfiguration of Spanning Tree Protocol) and IEEE
802.1d (Spanning Tree Protocol)
Layer 2 switching
VLAN support and tagging
: supports the IEEE 802.1Q (4,094 VLAN IDs) and up to 256 port-based VLANs simultaneously

Maximum power rating and maximum heat
dissipation are the worst-case theoretical
maximum numbers provided for planning the
