The HP ProCurve 2520-24-PoE Ethernet Switch is cost-effective and easy to use, making it suitable for small to medium-sized businesses that require PoE capabilities for their network. It's also a good option for enterprise networks that need a reliable, low-cost switch with advanced features.
Power and Energy Efficiency
The HP ProCurve 2520-24-PoE Ethernet Switch (J9138A) is designed to be power-efficient, providing energy savings while maintaining high performance.
- The switch supports 802.3af and 802.3at PoE standards, with a maximum PoE budget of 370W. This allows you to power devices such as IP phones, wireless access points and other PoE-enabled devices directly through the network cable, eliminating the need for additional power outlets.
- The switch has a maximum power consumption of 515.8W, which is relatively low compared to other similar switches.
- The switch supports Energy Efficient Ethernet (EEE) which reduces power consumption during periods of low network activity.
- The switch also has a feature called "Link aggregation control protocol (LACP) and Link Layer Discovery Protocol (LLDP) Power-Saving" that helps to reduce power consumption by putting inactive links into a low-power state.
- The switch also supports IEEE 802.3az Energy Efficient Ethernet (EEE) which reduces power consumption during periods of low network activity.
Network Management and Security features
- Access Control Lists (ACLs): The J9138A HP ProCurve 2520-24-PoE Ethernet switch has the ability to filter network traffic based on specific criteria, such as IP addresses, protocols, and port numbers. This feature allows for more granular control over network access and security.
- VLANs: The switch supports the creation of virtual LANs (VLANs), which allows for segmentation of network traffic and improved security. This feature allows for the creation of multiple isolated networks within the same physical infrastructure.
- Quality of Service (QoS): The switch has the ability to prioritize network traffic based on specific criteria, such as IP addresses, protocols, and port numbers. This feature ensures that critical network traffic, such as voice and video, is given priority over less important traffic.
- Port Security: The switch supports port security, which allows administrators to configure security settings for individual switch ports. This feature can be used to limit the number of MAC addresses that can be associated with a port, as well as to prevent unauthorized access to the network.
- SNMPv3: The switch supports SNMPv3, which allows for secure and encrypted management of the switch via SNMP. This feature provides an additional layer of security for network management.
- SSH and HTTPS: The switch supports SSH and HTTPS for secure remote management and access. This feature provides an additional layer of security for network management and access.
- RADIUS and TACACS+: The switch supports RADIUS and TACACS+ for centralized authentication and authorization of network access. This feature provides an additional layer of security for network access.

About New Bulk Pack Products
Different Types of Switches
Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).
The unmanaged switches offer fixed configurations on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.
The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.
The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.
Smart switches refer to switches that possess more features than those unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.
Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.
Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
