The Huawei S1720 28GWR 4X E AC switch is a high performance, enterprise level switch designed for small and medium sized businesses. Here's a breakdown of the key parameters mentioned:

1. 24 10/100/1000BASE T ports: This indicates that the switch has 24 Ethernet ports that support three different speeds:

  10BASE T: Ethernet at 10 Mbps

  100BASE T: Fast Ethernet at 100 Mbps

  1000BASE T: Gigabit Ethernet at 1000 Mbps (1 Gbps)

These ports use twisted pair copper cabling and are commonly used for connecting devices such as computers, servers, and other network equipment.

2. 4 10GE SFP+ ports: The switch also has 4 SFP+ (Small Form factor Pluggable Plus) ports that support 10 Gigabit Ethernet (10GbE) at speeds up to 10 Gbps. SFP+ ports are used for high speed connections and often employ optical fiber or direct attach copper cables.

3. Fixed AC power: This means that the switch is designed to be powered by an alternating current (AC) power source. The term "fixed" implies that the switch does not have a removable power supply unit, and it is not designed to be powered by a direct current (DC) source.

4. AC: This stands for "Alternating Current," which is the type of electrical power commonly used in homes and businesses. It contrasts with DC (Direct Current), which is used in some specialized applications and devices.

The Huawei S1720 28GWR 4X E AC switch is part of Huawei's S1720 series, which is known for its reliability, high performance, and advanced features suitable for small to medium sized enterprise networks. The mix of high speed copper and fiber ports allows for flexible network configurations and high speed data transmission.
