This HP ProCurve 2520-24-PoE Switch is ideal for small and medium businesses looking to deploy voice, video, and/or wireless solutions that require Power over Ethernet (PoE) connectivity. The managed switch includse support for dual-personality Gigabit ports that can be used for either copper or fiber connectivity. Fully managed via SNMP, with command-line interface (CLI), and graphical user interface (GUI), it also offers a Layer 2 feature set. In addition, this HP ProCurve switch provides deployment flexibility with compact, quiet, and energy-efficient designs.

Key Features

• Fully managed Layer 2 switch with 24 ports
• Power over Ethernet for voice, video, and wireless
• Energy-efficient design and quiet operation
• Rack-mountable and compact form factors

Management

• Choice of management interfaces:
  • Web graphical user interface (GUI): easy-to-use graphical interface allows configuration of the switch from any Web browser
  • Command-line interface (CLI): robust command-line interface provides advanced configuration and diagnostics
  • Simple Network Management Protocol (SNMPv2c/SNMPv3): allows switch to be managed with a variety of third-party network management applications
• Integration with HP ProCurve Manager: enables discovery, mapping, logging, and configuration via ProCurve Manager, available as a free download from the Web
• Virtual stacking: single IP address manages up to 16 switches
• Port mirroring: allows traffic to be mirrored on any port or a network analyser to assist with diagnostics or detecting network attacks
• Multiple configuration files: configuration file management tools allow up to three configuration files to be managed and stored on the switch
• Dual flash images: provide independent primary and secondary operating system files for backup while upgrading
• Network tools: command-line interface includes telnet client, ping, traceroute, and Layer 2 link test tools for diagnostics
• IEEE 802.1AB Link Layer Discovery Protocol (LLDP): automated device discovery protocol for easy mapping by network management applications
• Command authorisation: leverages RADIUS to link a custom list of CLI commands to individual network administrator's login; also provides an audit trail
• Logging: local and remote logging of events via SNMP (v2c and v3) and syslog
• IPv6 host: allows switches to be managed using IPv6 protocols
• RMON: provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events
• Find-Fix-Inform: finds and fixes common network problems automatically, then informs administrator
• Front-panel LEDs:
  • Locator LED: allows users to set the locator LED on a specific switch to either turn on, blink, or turn off; simplifies troubleshooting by making it easy to locate a particular switch within a rack of similar switches
  • Per-port LEDs: provides an at-a-glance view of status, activity, speed, and full-duplex operation
  • Power and fault LEDs: power LED and fault LEDs display any issues

Connectivity

• Auto-MDIX: automatically adjusts for straight-through or crossover cables on all ports
• Small Form-Factor Pluggable (SFP) slots: dual-personality ports allow for either copper or fiber connectivity such as Gigabit-SX, -LX, -LH, and -BX or 100-FX and -BX
• 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 FAQ for more details)
• RJ-45 serial console port: easily accessible on front of unit to access switch CLI

Performance

• Switch on a chip: highly integrated, high-performance switch design with a non-blocking architecture

Resiliency and high availability

• Port trunking and link aggregation:
  • 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)
