Without accessories Huawei Switch / Basic Model Data Manufacturer: Huawei Model: S5720I-12X-P-WH-SI-DC Device Type: Layer 3 Smart Network Switch. It is a device designed for high endurance and harsh industrial or outdoor environments (Industrial Switch). Manufacturing Date Indicated: 08 / 2019 Power and Operating Specifications Current Type: Direct Current (DC). DC Voltage Rating: Operates at a voltage ranging from 50 to 56 Volts (50-56 V). Current Intensity: 5.5 Amperes (5.5 A). Power over Ethernet (PoE) Support: The letter P in the model name indicates that it supports PoE technology to power connected devices (such as surveillance cameras or wireless access points) directly via the network cable. Ports & Performance Details According to Huawei's standard model naming (12X): Downlink Ports: Typically contains 8 Gigabit Ethernet ports (10/100/1000 Base-T) that support PoE. Uplink Ports: Contains 4 x 10 Gigabit SFP+ ports for high-speed network connectivity. Huawei Router / You can operate and network this device in two main ways: Method 1: Operation via Network Cable (PoE) - This is the best and easiest method. Method 2: Operation via Traditional Power Adapter (DC) Manufacturer: Huawei. Technology Type: Wi-Fi 6 Certified (Sixth Generation Wi-Fi), characterized by high capacity to handle connected devices, ultra-fast data transfer speeds, and very low latency. Design: Circular, equipped with rear cooling fins (Heatsink) for effective heat dissipation, and dedicated ports for ceiling or wall mounting. Ports: GE Port (Gigabit Ethernet): For connecting the network cable and transferring data at speeds up to 1 Gigabit/second. 5GE/PoE_IN Port (or Network Port Supporting High Speeds and Power Input): This port supports PoE (Power over Ethernet) technology, meaning the device can operate and draw power directly via the network cable without needing a nearby electrical outlet. DC 48V Traditional Power Port: For using a standard power adapter (female/male) if not using PoE technology. Theoretical Maximum Total: The device supports connection of up to 1024 users (or devices) simultaneously as a hardware specification maximum. Recommended Number for Stable Performance: For excellent performance and stable internet speed without slowness, it is generally recommended that the actual number of active users does not exceed 100 to 200 users simultaneously, depending on the nature of use and the amount of data consumed.
