Hello If it was working and now it stopped working you might have to check show log
to see why it stopped working.
You might have to increase power budget if incase the slot is oversubscribed.
Details are available in concepts guide page 431
Power Checking for PoE ModulePoE modules require more power than other I/O modules.
When a chassis containing a PoE module is booted or a new PoE module is inserted, the power drain is
calculated. Before the PoE module is powered up, the chassis calculates the power budget and powers
up the PoE module only if there is enough power. The chassis powers up as many I/O modules as
possible with lower-numbered slots having priority.
Note
If your chassis has an inline power module and there is not enough power to supply the
configured inline power for the slot, that slot will not power on; the slot will not function in
data-only mode without enough power for inline power.

I have seen reseating the card solves these kind of problems.
But you might have to identify the root cause.
