Problem with the lanpower

[fripouille]

Hello

On OS6560-P24Z8 (version 8.5.164.R01), when I enter the command "show lanpower slot 1/1", I get this response:
"NI not present in ChassisId 1 slot 1!"

The POE works very well since the cameras connected to the ports work but I have no way of recovering the POE consumption information.
What can I do ?
Is it a hardware problem?
Could a simple reboot of the switch be enough?

Thank you in advance for your feedback.

Reboot should solve the issue. But better is to update to an actual release - include the uboot.
