Perhaps you have dual power supplies in them?

RPS is showing absent ... I am getting pictures of power connected but not sure if it is dual power supply not showing in the output ?

[mehtarahul1998]

Just verified through pictures ..All switches have connected single power supply.

Can you post the output of "show inventory" to confirm the part numbers please.

Perhaps you have had a partial power supply failure.  For example, perhaps the PoE portion is offline due to a fault, but the rest of the power supply is working.

What software version are you using?  There is a slim chance there is an issue with the power controller modules.
