It is designed for small and medium-sized businesses and enterprise networks. It supports advanced features such as Quality of Service (QoS), VLANs, and Power over Ethernet (PoE) and PoE+ support. It also offers a variety of security and access control features, as well as management and monitoring capabilities.

This switch supports static and dynamic routing, enabling it to perform complex routing functions such as inter-VLAN routing, and it also supports access control lists (ACLs) and link aggregation control protocol (LACP) for increased security and bandwidth efficiency.

The HPE JG927A 1920-48G switch is also energy-efficient, with features such as Energy Efficient Ethernet (EEE) and power-saving capabilities, which can help reduce power consumption and operating costs. It also supports HPE's Intelligent Resilient Framework (IRF) stackable architecture, allowing multiple switches to be interconnected and managed as a single device, providing high availability, resiliency, and scalability.

Layer 3 Routing

One of the standout features of the JG927A is its Layer 3 routing capability. This means it can perform routing functions in addition to standard Layer 2 switching. Layer 3 switches are essential for creating complex networks, as they can route traffic between different subnets. This enables the segregation of network traffic for improved security and efficiency.

Rack-Mountable Design

The JG927A is rack-mountable, making it suitable for installation in standard server racks. This design is space-efficient and ensures neat and organized cabling within your data center or network closet. Another important feature of the HPE JG927A 1920-48G RJ-45 Ethernet Switch is its rack-mountable design. This is especially relevant for businesses with limited space in their network closets or data centers. The switch can be easily mounted in a standard 19-inch rack, which is the industry standard for networking equipment.

Rack mounting not only saves space but also provides a neat and organized way to manage your network infrastructure. It simplifies cable management, improves airflow, and makes it easier for network administrators to access and maintain the equipment.

Small Form-Factor Pluggable (SFP) Support

The JG927A 1920-48G comes equipped with 4 Small Form-Factor Pluggable (SFP) ports. These ports offer a high degree of flexibility in connecting the switch to other networking equipment, especially when extended distances are involved.

SFP ports are often used for connecting switches to fiber optic cables, which are capable of transmitting data over much longer distances than traditional copper Ethernet cables. This is particularly useful when connecting switches in different parts of a building or across multiple buildings in a campus network.

SFP modules are hot-swappable, meaning you can insert or remove them while the switch is powered on. This feature simplifies network maintenance and allows for easy scalability. You can choose the appropriate SFP module based on your specific networking requirements, whether it's for single-mode or multi-mode fiber optics or other connectivity needs.

Command-Line Interface (CLI)

For advanced users and experienced network administrators, the JG927A offers a command-line interface (CLI). The CLI provides a text-based way to configure and manage the switch, offering greater control over its settings. This is especially useful for fine-tuning configurations and automating tasks.

Network administrators familiar with CLI interfaces can take advantage of the JG927A's command-line capabilities to streamline their network management processes.

SNMP Support

Simple Network Management Protocol (SNMP) is a standard protocol for monitoring and managing network devices. The JG927A supports SNMP, allowing it to be integrated into network management systems for centralized monitoring and control. SNMP enables administrators to gather information about the switch's status, performance, and traffic statistics.

Management Capabilities

The JG927A 1920-48G is a manageable switch, meaning it offers advanced management features that enable you to monitor and control your network effectively. It supports various management protocols and can be configured through a web-based interface or command-line interface (CLI). This flexibility is essential for network administrators looking to tailor the switch's settings to their specific needs.

Desktop or Rack-Mountable Options

While the JG927A is rack-mountable, it also offers the flexibility to be used as a desktop switch. This means you can choose the installation method that best suits your network setup. The ability to switch between these configurations makes the JG927A adaptable to a variety of environments.

Power over Ethernet (PoE) and PoE+ Support

The HPE JG927A 1920-48G switch supports Power over Ethernet (PoE) and PoE+ (IEEE 802.3at) which allows it to provide power to devices connected to its Ethernet ports. This feature allows network administrators to power devices such as wireless access points, IP phones, and security cameras, without the need for an additional power source.

PoE+ support allows the switch to provide up to 30 watts of power per port, which is enough to power high-power devices such as pan-tilt-zoom cameras and access points that require more power. PoE+ allows the switch to provide power to more devices than traditional PoE, which provides only 15.4 watts of power per port.

The HPE JG927A 1920-48G switch supports a maximum of 370W of PoE power, which allows it to power a large number of PoE-enabled devices. Additionally, it also allows for the management of PoE power allocation, and it can detect and protect against overload conditions, which allows to avoid power outages and damage to the devices.

Power over Ethernet (PoE) and PoE+ support is a valuable feature for businesses and enterprise networks, as it allows for the deployment of IP-based devices without the need for additional power cables and outlets. This can save on installation and maintenance costs and also more flexibility when it comes to device placement.

Quality of Service (QoS) and Quality of Experience (QoE)

The HPE JG927A 1920-48G switch supports Quality of Service (QoS) and Quality of Experience (QoE) features, which allows network administrators to prioritize network traffic and ensure that critical applications and users receive the necessary bandwidth and low latency required for optimal performance.

QoS on the HPE JG927A 1920-48G switch is implemented using a variety of techniques such as traffic prioritization, bandwidth allocation, and congestion control. This allows network administrators to prioritize network traffic based on the type of application or user, ensuring that critical applications such as voice and video receive the necessary bandwidth and low latency required for optimal performance.

The switch also supports QoS features such as Differentiated Services Code Point (DSCP) and IEEE 802.1p, which allow network administrators to prioritize network traffic based on the type of application or user. Additionally, it supports Quality of Service (QoS) policies such as Weighted Round Robin (WRR), Strict Priority (SP), and Hybrid.

QoE, on the other hand, refers to the end-user experience when using the network. It includes factors such as application response time, video quality, and audio quality. QoE is dependent on the end-user's perception and can be affected by various factors such as network congestion, packet loss, and jitter. By monitoring and optimizing QoE, network administrators can ensure that the network is providing a high-quality experience to users.

Security Features

Network security is a top priority for organizations, and the JG927A includes security features to protect your network. These features can help safeguard your data and prevent unauthorized access.

Some of the security features include access control lists (ACLs) and 802.1X network access control, which allow you to control who can access the network and what they can do once connected. You can also implement port security to restrict access to specific ports based on MAC addresses, adding an extra layer of security.

Enterprise Networks

The JG927A is well-suited for medium and large enterprises that require a high-performance network infrastructure. Its 48 ports and Layer 3 routing capabilities make it an excellent choice for connecting numerous devices and segmenting network traffic efficiently.

In enterprise environments, network reliability, scalability, and security are of paramount importance.
