Product Overview of the HPE J9728-61002 Switch

In the world of networking, the HPE J9728-61002 48 Ports 2920-48G Switch stands as a powerful and versatile solution. This comprehensive review will delve into its features, specifications, and the benefits it brings to the table for network administrators and businesses.

Key Features

  • Port Configuration: The switch boasts a total of 48 ports supporting Gigabit Ethernet, providing high-speed connectivity for various devices. Additionally, it features 4 shared Gigabit Small Form-Factor Pluggable (SFP) ports, adding flexibility for fiber optic connections.
  • Gigabit Performance: With a total throughput of 176 gigabits per second (Gbps), the 2920-48G ensures a seamless flow of data across the network. This high performance is crucial for modern businesses dealing with bandwidth-intensive applications.
  • Processing Power: Equipped with a robust 1 X Arm 625Megahertz processor, the switch efficiently manages data traffic and ensures optimal performance across all connected devices.
  • Management Capabilities: The switch is a managed device, allowing administrators to have granular control over the network. This includes features like VLAN support, QoS (Quality of Service) management, and security protocols.
  • Desktop Form Factor: Designed for convenience, the 2920-48G switch comes in a desktop form factor. This makes it suitable for deployment in various office environments, providing easy access for maintenance and management.

Use Cases

  • Enterprise Networks: For large enterprises with numerous connected devices, the 2920-48G switch proves invaluable. Its high port count and gigabit performance ensure that data flows seamlessly, supporting the demands of a bustling corporate network.
  • Data Centers: In data center environments, where speed and reliability are paramount, the switch's Gigabit Ethernet ports and high throughput become essential. The inclusion of SFP ports further enhances connectivity options.
  • Small to Medium Businesses (SMBs): Even in smaller business settings, having a managed switch is beneficial. The 2920-48G provides the necessary features for network optimization, ensuring that SMBs can operate efficiently.

Stackability of the J9728-61002 HPE 2920-48G Switch

The J9728-61002 HPE 2920-48G Switch is a stackable switch, which means it can be connected to other J9728-61002 HPE 2920-48G switches using HPE's FlexStack or FlexStack Plus module to create a single, logical switch with increased port density and network resiliency. The FlexStack module provides a 20 Gbps connection between stack members, while FlexStack Plus provides a 40 Gbps connection. Up to four switches can be stacked together using FlexStack, and up to eight switches can be stacked using FlexStack Plus.

Power over Ethernet (PoE) Support

Power over Ethernet (PoE) support on the HPE J9728-61002 2920-48G Managed 48 Ports Switch allows for the delivery of power to devices connected to the switch through the Ethernet cables. This eliminates the need for separate power cables and allows for the installation of devices in locations where power outlets may not be easily accessible. The switch supports PoE on all 48 ports and can provide up to 30W of power per port, allowing for the power of multiple devices such as IP phones, wireless access points, and security cameras. This feature makes the switch ideal for use in environments such as offices, schools, and retail stores where devices need to be placed in convenient locations without the need for additional power outlets.

Quality of Service (QoS) and Traffic Prioritization

  • Quality of Service (QoS) refers to the ability of a network to prioritize and manage different types of network traffic to ensure that critical applications and services receive the necessary bandwidth and resources to function properly. This is particularly important in environments where multiple users and devices are sharing the same network and competing for bandwidth and resources.
  • Traffic prioritization is a key component of QoS. It involves assigning different levels of priority to different types of network traffic, such as voice, video, and data. This ensures that critical applications and services receive the necessary bandwidth and resources, while less important traffic is given a lower priority.
  • The HPE J9728-61002 2920-48G Managed 48 Ports Switch is designed to support QoS and traffic prioritization. It allows network administrators to assign different levels of priority to different types of traffic, such as voice, video, and data. This ensures that critical applications and services receive the necessary bandwidth and resources, while less important traffic is given a lower priority.
  • The switch also supports advanced QoS features such as bandwidth control, traffic shaping, and congestion management. This allows network administrators to fine-tune the network to ensure that critical applications and services receive the necessary resources while maintaining overall network performance and stability.
