Overview of HPE JG927A 1920-48G Switch

The HPE JG927A 1920-48G is a Layer 3 manageable rack-mountable switch that offers 48 Gigabit Ethernet ports and 4 SFP ports. 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.

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 provides 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.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

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.
