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.

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.
