The Huawei S1700 26R 2T AC switch is a managed Ethernet switch designed for small and medium sized enterprise networks. Here's a breakdown of the parameters mentioned:

1. Huawei: The manufacturer of the switch, a leading global provider of information and communications technology (ICT) infrastructure and smart devices.

2. S1700 26R 2T AC: The model number of the switch, which indicates specific features and capabilities. The "S" stands for switch, "1700" is the series, "26" indicates the number of 10/100BASE T ports, "R" denotes the presence of 2 10/100/1000BASE T ports, "2T" signifies two Gigabit ports, and "AC" means it has an AC power supply.

3. 24 10/100BASE T ports: The switch has 24 Ethernet ports that support both 10 Mbps (Ethernet) and 100 Mbps (Fast Ethernet) data rates. These ports are typically used for connecting devices such as computers, printers, or other network devices.

4. 2 10/100/1000BASE T ports: The switch also has two additional Ethernet ports that support 10 Mbps, 100 Mbps, and 1000 Mbps (Gigabit Ethernet) data rates. These ports are useful for connecting devices that require higher data rates, such as servers or high performance network storage devices.

5. Fixed AC power: The switch comes with a built in AC power supply, which means it can be connected directly to a standard electrical outlet for power. This is in contrast to some switches that may require a separate power adapter or have a DC power input.

This switch is designed to provide reliable and high performance connectivity for businesses. Its features may include VLAN support for network segmentation, Quality of Service (QoS) for traffic prioritization, and security features such as access control lists (ACLs) and port security. The managed aspect of the switch also allows for configuration and monitoring through a web interface or command line interface (CLI), providing greater control over the network.
