How Can I Determine Whether a Device Supports PoE?
Run the display device [ slot slot-id ] command to view information about the device.
Whether switches support PoE depends on the hardware. Non-PoE switches cannot be changed to PoE switches through software upgrades. A switch that meets any of the following conditions is a PoE switch:
- The device name contains PWR or PWH.
- The switch is released in V200R013C02 or later versions and provides new downlink interface types UM, P or U.
