Network Connectivity and Management

The HP ProCurve 2520-24-PoE Ethernet Switch (J9138A) provides network connectivity and management capabilities for small to medium-sized businesses and enterprise networks.

Network Connectivity:

  • The switch has 24 10/100Mbps ports and 2 Gigabit Ethernet SFP ports for connecting devices such as computers, servers, and other network devices.
  • It supports 802.3af and 802.3at PoE standards, allowing you to power devices such as IP phones and wireless access points directly through the network cable.
  • The switch also supports advanced features such as VLANs and Quality of Service (QoS) for improved network performance and security.


  • The switch can be configured and managed through a web interface or command-line interface (CLI).
  • The web interface provides a user-friendly interface for configuring basic settings, while the CLI allows for more advanced configuration options.
  • The switch also supports SNMP, allowing you to manage and monitor the switch remotely.
  • Additionally, the switch can be managed centrally through HP ProCurve Manager, HP's network management software.

Security and Access Control

The J9138A HP ProCurve 2520-24-PoE Ethernet switch has several security and access control features to help protect your network.

  • Access control lists (ACLs) can be used to restrict access to specific network resources based on the source or destination IP address, protocol, or port number.
  • Port security can be used to limit the number of MAC addresses that can be learned on a specific port, preventing unauthorized devices from accessing the network.
  • The switch supports IEEE 802.1X port-based authentication, which can be used to control access to the network based on the identity of the user or device.
  • The switch also supports SNMPv3, which provides secure management of the switch using authentication and encryption.
  • Additionally, the switch supports SSHv2 and SSL for secure access to the switch's command-line interface and web-based management interface.

It's important to note that it's important to keep the switch firmware up to date with the latest security updates.

Compatibility and Interoperability

The J9138A HP ProCurve 2520-24-PoE Ethernet 24 Ports Switch is compatible and interoperable with a variety of devices and systems, including:

  • Network devices from other manufacturers: The switch is fully compliant with IEEE 802.3 standards, which means it can seamlessly connect to other devices, such as routers, servers, and other switches from different vendors.
  • Power over Ethernet (PoE) devices: The switch supports PoE on all 24 ports, which allows it to power devices such as IP phones, wireless access points, and security cameras over the Ethernet cable.
  • Virtual LANs (VLANs): The switch supports VLANs, which allows for the segmentation of the network into different logical networks, improving security and performance.
  • Quality of Service (QoS): The switch supports QoS, which prioritizes different types of network traffic, such as voice and video, to ensure that critical applications have the bandwidth they need.
  • Link aggregation: The switch supports link aggregation, which allows multiple ports to be grouped together to form a single logical link, providing increased bandwidth and redundancy.
