%C6K_POWER-SP-6-NOLPP: Because of lack of system power, devices that require the system to
power them on may not come up within one second.
This message indicates that the local power pools have been deallocated. The module
firmware cannot power up the device until it has received authorization for power
allocation from the software running on the supervisor engine.
Please share the o/p of "show mod", "show power","show environment" & "show log" from the switch.
It looks like that the system doesn't have enough power to bring up this module.
