More Information
J4903A is a model number for the HPE ProCurve 2824, a 20-port Ethernet switch with 24 ports. The switch has 20 10/100/1000Base-T Ethernet ports, which support 10 Mbps, 100 Mbps, and 1 Gbps Ethernet connections, providing flexibility and scalability for high-speed data transmission.
In addition to its Ethernet ports, the HPE ProCurve 2824 switch also has a management port that provides remote access to the switch for configuration, monitoring, and troubleshooting purposes. The switch supports a variety of features and protocols, including VLANs, Quality of Service (QoS), and Link Aggregation Control Protocol (LACP).
The HPE ProCurve 2824 switch is designed for use in small and medium-sized businesses, as well as large enterprise networks. It is ideal for applications that require high-speed data transfer, such as video and voice over IP, multimedia applications, and server virtualization.
With its advanced security features and performance, the HPE ProCurve 2824 switch is a cost-effective and reliable choice for networking solutions.
Exceptional Reliability
The J4903A HPE ProCurve 2824 is a 20-port switch that has 24 10/100/1000Base-T Ethernet ports. This means that it can support up to 24 devices that can connect to it using Ethernet cables. The switch has exceptional reliability, meaning that it is designed to perform consistently and without interruption. This is achieved through a number of features, including:
- Redundant power supplies: The switch has two power supplies, so if one fails, the other can take over to ensure that the switch continues to operate.
- Hot-swappable components: The switch has hot-swappable components, meaning that they can be replaced without shutting down the switch, which helps to reduce downtime.
- Quality of Service (QoS): The switch has QoS capabilities, which allow it to prioritize different types of traffic, such as voice or video, so that they are delivered with minimal delay and jitter.
- Layer 3 switching: The switch supports Layer 3 switching, which allows it to route traffic between different networks, making it a more versatile device.
- SNMP management: The switch supports Simple Network Management Protocol (SNMP), which allows it to be managed and monitored remotely, making it easier to troubleshoot and resolve issues.
High Performance
The J4903A HPE ProCurve 2824 is a high-performance switch designed for use in small to medium-sized businesses and enterprise networks. It features 20 10/100/1000Base-T Ethernet ports, which allow for fast and reliable connectivity to a wide range of devices. These ports support both auto-negotiation and auto-mdix, which ensures that the switch can automatically detect the type of cable and speed being used, eliminating the need for manual configuration.
The switch also comes with advanced features such as Quality of Service (QoS) and VLAN support, which allow for improved network performance and security. QoS allows for prioritization of network traffic, ensuring that critical applications and services receive the bandwidth they need. VLANs allow for segmentation of the network, which improves security and improves network performance by reducing broadcast traffic.
The ProCurve 2824 also includes a built-in web-based management interface, which allows for easy configuration and monitoring of the switch. Additionally, the switch is built with a durable and robust design, making it suitable for use in harsh environments.
Advanced Quality of Service (QoS) Features
J4903A HPE ProCurve 2824 is a 20-port switch that supports 10/100/1000Base-T Ethernet and provides advanced Quality of Service (QoS) features. The switch provides 24 ports that can be used to connect various devices, such as computers, printers, and servers, to the network.
QoS features are designed to ensure that critical network traffic, such as voice or video, receives priority over less important traffic, such as file transfers. This helps prevent network congestion and ensures that high-priority traffic is transmitted with minimal delay. The J4903A HPE ProCurve 2824 switch provides several QoS features, including:
- Class of Service (CoS) - This feature assigns a priority level to different types of traffic based on their importance. This allows the switch to prioritize certain types of traffic, such as voice or video, over others.
- Traffic Shaping - This feature controls the rate of network traffic to prevent congestion and ensure that high-priority traffic is transmitted without delay.
- Prioritization - This feature allows the switch to prioritize different types of traffic based on the importance of the data they are carrying. This helps prevent network congestion and ensures that high-priority traffic is transmitted without delay.
- Quality of Service (QoS) Mapping - This feature maps different types of network traffic to different priority levels, ensuring that critical network traffic is given priority over less important traffic.

About Refurbished 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).
Unmanaged Switches
The unmanaged switches offer fixed configuration 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.
Managed Switches
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
Smart switches refer to switches that possess more features than those of 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
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.
