Hello friend! hope it can help:
Root Cause:
After the switch is enabled to check the compatibility of PDs, the switch can detect and provide power to the PDs that do not comply with the 802.3af or 802.3at standard or the standard PDs that are detected as non-standard PDs because of the external environment. If compatibility check is disabled, the switch cannot provide power to the non-standard PDs.
Solution:
Run below command on the interfaces that is connected to non standard PDs

Thanks!
