The Huawei S1720 52GWR PWR 4P AC is a managed switch that offers a range of features and capabilities for businesses and organizations. Here's a breakdown of the parameters mentioned:

1. 48 10/100/1000BASE T ports: This indicates that the switch has 48 Ethernet ports that support three different speeds   10 Mbps (Fast Ethernet), 100 Mbps (Gigabit Ethernet), and 1000 Mbps (10 Gigabit Ethernet). The "T" in the term stands for Twisted Pair, which is a type of Ethernet cable commonly used in local area networks (LANs).

2. 4 GE SFP ports: GE stands for Gigabit Ethernet, and SFP stands for Small Form factor Pluggable. These are high speed ports that use SFP modules to connect to fiber optic or copper cables. The switch has four of these ports, allowing for flexible connectivity options.

3. Fixed AC power: This means that the switch is powered by an alternating current (AC) power supply, which is the standard type of electricity used in most buildings. The term "fixed" indicates that the power supply is built into the device and cannot be changed.

4. PoE+: PoE stands for Power over Ethernet, which is a technology that allows network cables to carry both data and electrical power to devices such as wireless access points, IP cameras, and VoIP phones. The "+" in PoE+ indicates that the switch supports the enhanced version of this technology, which can deliver more power (up to 30 watts) over the Ethernet cables. This is particularly useful for devices that require more power than the standard PoE can provide.

5. Managed switch: This term indicates that the switch can be configured and managed through a network management system or software. Managed switches offer more control over network traffic and security compared to unmanaged switches.

In summary, the Huawei S1720 52GWR PWR 4P AC is a versatile and powerful managed switch that offers a mix of high speed Ethernet ports, flexible connectivity options with SFP ports, and advanced features like PoE+ for powering network devices.
