The Huawei S1720 52GWR 4X AC is a managed switch that offers a range of features and capabilities for businesses and organizations. Here are some key parameters and their introduction:

1. 48 10/100/1000BASE T Ports: This switch supports 48 Gigabit Ethernet (GigE) ports that can operate at 10, 100, or 1000 Mbps (10/100/1000BASE T). These ports are suitable for connecting various devices such as computers, servers, printers, and other network equipment.

2. 4 10GE SFP+ Ports: The switch also includes four 10 Gigabit Ethernet (10GbE) SFP+ (Small Form factor Pluggable) ports. These ports can be used to connect to other high speed devices or to extend the network using fiber optic cables. SFP+ ports are versatile and can support different types of transceivers, including SR (short range), LR (long range), and ER (extended range) modules.

3. Fixed AC Power: The switch has a fixed AC power supply, which means it is designed to be powered by an AC power source, such as the mains electricity in a building. This is in contrast to some switches that might have a choice between AC and DC power sources or that use a power over Ethernet (PoE) feature to power the device.

4. Managed Switch: Unlike unmanaged switches, a managed switch like the S1720 52GWR 4X AC allows for configuration and monitoring of the network. This is done through a web interface, command line interface (CLI), or network management software. Managed switches are beneficial for larger networks where traffic prioritization, VLAN (Virtual Local Area Network) creation, and security features are necessary.

5. Web Management: The switch can be managed through a web interface, which provides an easy to use graphical interface for configuring and monitoring the switch.

6. CLI Access: For more advanced configurations, the switch can also be managed through a command line interface, which is accessible via a console port, Telnet, or SSH (Secure Shell).

7. PoE Capability: While the switch itself is powered by AC, it may also support PoE (Power over Ethernet) on some or all of its ports, allowing it to power devices like IP cameras or VoIP phones directly through the Ethernet cable.

8. Security Features: Managed switches often include security features such as access control lists (ACLs), port security, and VLAN tagging to help protect the network from unauthorized access and to segregate network traffic.

9. QoS (Quality of Service): The switch may support QoS features, which allow for the prioritization of certain types of network traffic to ensure that critical applications receive the bandwidth they need.

10. L2/L3 Features: Depending on the model, the switch may support Layer 2 (L2) and Layer 3 (L3) functionalities, which include VLAN support, static routing, and potentially more advanced features like dynamic routing protocols.

11. Redundancy and Reliability: The switch may include features to ensure high availability and reliability, such as redundant power supplies, loop prevention, and rapid recovery from network failures.

12. Energy Efficiency: Modern switches often include features to reduce power consumption, such as energy efficient Ethernet (EEE) or other power saving technologies.

These parameters provide a comprehensive overview of the capabilities and features of the Huawei S1720 52GWR 4X AC switch, highlighting its suitability for medium to large enterprise networks that require high speed connectivity, advanced management, and security features.
