Description
Layer 2 Switching Capabilities
J9299A#ACC is a model number for a HP E2520-24G-PoE Ethernet Switch. It is a 24-port manageable switch, meaning it can be configured and managed remotely. It operates at Layer 2, meaning it is capable of forwarding and filtering data based on MAC addresses and provides basic switching functions, but does not support routing (forwarding based on IP addresses). The PoE (Power over Ethernet) feature allows the switch to power connected devices through the Ethernet cables, eliminating the need for separate power supplies.
Quality of Service (QoS) Features
The J9299A#ACC HP E2520-24G-PoE Ethernet Switch is a 24-port manageable switch that provides Quality of Service (QoS) features. These features are designed to prioritize network traffic to ensure that critical applications receive the bandwidth they need to operate optimally.
The switch supports PoE (Power over Ethernet) and can provide power to connected devices, such as phones, cameras, or access points, reducing the need for additional power supplies. The switch also supports auto-negotiation, automatic detection of the speed, and duplex mode of connected devices.
QoS features include:
- Class of Service (CoS)
- Differentiated Services Code Point (DSCP)
- Traffic Policing and Shaping
With these features, the switch can classify and prioritize different types of traffic based on their importance. For example, voice and video traffic can be given priority over email or web browsing traffic to ensure clear communication and minimize delays.
Physical and Environmental Characteristics
The J9299A#ACC HP E2520-24G-PoE Ethernet Switch is a manageable switch with 24 ports. It has the following physical and environmental characteristics:
- Dimensions: The switch measures 4.5 x 28.5 x 21.6 cm and weighs 2.5 kg.
