The Huawei S1720 10GW PWR 2P AC switch is a managed switch designed for small and medium sized businesses. Here's a breakdown of the parameters mentioned:

1. 8 10/100/1000BASE T ports: This refers to the switch having eight Gigabit Ethernet (GigE) ports that support three different speeds: 10 Mbps (Ethernet), 100 Mbps (Fast Ethernet), and 1000 Mbps (Gigabit Ethernet). These ports are commonly used for connecting devices such as computers, printers, and other network devices.

2. 2 GE SFP ports: The switch has two Gigabit Ethernet Small Form factor Pluggable (SFP) ports. These ports allow for the use of SFP modules, which can be used for various types of network connections, such as fiber optic or copper, depending on the module. This provides flexibility in connecting the switch to different types of networks.

3. PoE+: This stands for Power over Ethernet Plus. It is a standard that allows network cables to be used to supply both power and data to devices such as wireless access points, IP cameras, and VoIP phones. The "Plus" indicates that the switch supports higher power output compared to the standard PoE, which can be beneficial for devices that require more power.

4. Fixed AC power: This indicates that the switch is powered using an alternating current (AC) power source, as opposed to a direct current (DC) source. The term "fixed" suggests that the power supply is built into the switch and cannot be easily replaced or upgraded. This is a common configuration for many network switches, especially those designed for indoor use.

5. Huawei S1720 10GW PWR 2P AC: This is the model number of the switch, which can be used to look up specific features, specifications, and documentation for the device. Huawei is a well known manufacturer of networking equipment, and the S1720 series is part of their product lineup.

In summary, the Huawei S1720 10GW PWR 2P AC is a versatile managed switch that supports a mix of Gigabit Ethernet ports, including SFP ports for flexible connectivity options, and PoE+ for powering network devices over Ethernet cables. Its fixed AC power supply makes it suitable for standard indoor network installations.
