Which Switch Models Support the PoE Function?
You can use the display device command to check a switch's product name and determine whether the switch supports the PoE function according to its product name.
If the product name contains PWR, this switch model supports the PoE function.
If the product name does not contain PWR, this switch model does not support the PoE function.
Among modular switches, only the S7700 series switches support the PoE function. The PoE card of an S7700 is ES0D0G48VA00.
