what device that has been connected to the port and denied, do you have LLDP enabled (if 3rd party device) ?
Can you post the below output :
show verison
#show modules
#show power inline (full output)
#show run interface GigabitEthernet1/0/47
#show run interface GigabitEthernet1/0/48
last option reload the switch and see if that fix the issue
some troubleshooting tips :

Power deny probably because those ports have triggered a loopback alarm.
Could be a faulty cable.
Please post the complete output to the command "sh post".
