The PoE controller has likely failed.
Run diagnostics on the switch with the command run diagnostics extended {slot <slot#>}, then check the output of diagnostics with the command show diagnostics.

If "show diagnostics" reports "
POE check state loop test failed," or the switch still does not deliver power following the diagnostics, submit an RMA.
