The Huawei S1720 52GWR 4X E AC is a managed switch designed for enterprise networks. Here is a parameter introduction for the switch:

1. Model: S1720 52GWR 4X E AC   This is the specific model of the switch, indicating it belongs to the S1720 series, which is part of Huawei's SmartCloud series of switches.

2. 48 10/100/1000BASE T ports: The switch has 48 Gigabit Ethernet (GE) ports that support 10/100/1000BASE T speeds. These ports can be used to connect various devices, such as computers, servers, or other network equipment.

3. 4 10GE SFP+ ports: The switch also has four 10 Gigabit Ethernet (10GE) SFP+ (Small Form factor Pluggable) ports. These ports allow for high speed connections using SFP+ transceivers, which can be used for long distance transmission or connecting to other high speed network devices.

4. Fixed AC power: The switch is equipped with a fixed AC power supply, which means it requires a standard mains power connection to operate. This is in contrast to some switches that may have the option for either AC or DC power input.

5. Managed switch: The S1720 52GWR 4X E AC is a managed switch, meaning it can be configured and monitored using a network management system or through the web interface. This allows for advanced features such as VLANs, Quality of Service (QoS), and security settings.

6. PoE+ support: The switch supports Power over Ethernet Plus (PoE+) on all 48 10/100/1000BASE T ports, allowing you to power devices like IP cameras, VoIP phones, and access points through the Ethernet cable.

7. Stackable: The S1720 series switches are stackable, which means you can combine multiple switches to create a single, high performance network device. This is useful for expanding the network capacity and simplifying management.

8. L2/L3 features: The switch supports Layer 2 and Layer 3 features, such as static routing, RIP (Routing Information Protocol), and OSPF (Open Shortest Path First), making it suitable for small to medium sized enterprise networks.

9. Comprehensive security features: The S1720 52GWR 4X E AC switch offers various security features, including access control lists (ACLs), MAC address binding, and port security, to protect your network from unauthorized access and potential threats.

10. Energy efficient: The switch is designed to be energy efficient, with features such as energy efficient Ethernet (EEE) and air circulation to reduce power consumption and ensure reliable operation.
