The downlink electrical interfaces of PoE switches support PoE power supply, with up to 30 W power on each interface. The maximum power supply distance is 100 m.
Only ES0D0G48VA00 (S7700)/LE0DG48VEA00 (S9300) cards of modular switches (S7700/S9700/S9300/S12700) support PoE power supply.
If the switch connects to 48 V standard PoE powered devices but cannot negotiate power supply capabilities with the devices, you can run poe force-power on the interfaces to forcibly power on the devices.
By the way, you can check the price of Huawei S Switches.
