The Huawei S1720X 32XWR E AC is a high performance, enterprise level switch that is designed to meet the demands of modern networks. Here is a brief introduction to the parameters you mentioned:

1. 32 10GE SFP+ ports: This switch has 32 ports that support 10 Gigabit Ethernet (10GE) connections using Small Form factor Pluggable Plus (SFP+) transceivers. SFP+ is a popular interface for high speed data transmission, and having 32 of these ports allows for a high density, high bandwidth network.

2. Fixed AC power: This indicates that the switch is designed to be powered using an Alternating Current (AC) power source. The term "fixed" suggests that the power supply is built into the device and is not interchangeable with other types of power sources (like a DC power supply). This is in contrast to some switches that might offer both AC and DC power options or are designed to be powered by a separate power module.

3. Huawei S1720X Series: This switch is part of Huawei's S1720X series, which is known for its high performance, reliability, and advanced features suitable for enterprise environments. The series typically includes switches with various port configurations and capabilities to meet different network requirements.

4.  E: This suffix might denote a specific model or feature set within the S1720X series. It could indicate a model with enhanced capabilities, such as higher performance, additional features, or specific certifications.

5.  AC: As mentioned, this indicates that the switch is powered by an AC power source.

In summary, the Huawei S1720X 32XWR E AC switch is a high capacity, enterprise grade device designed for networks that require high speed data transmission and reliability. Its 32 10GE SFP+ ports allow for extensive connectivity options, and its fixed AC power supply ensures a stable power source for the device.
