Dinesh,
It may be because of the PEM is not properly seated/screwed in the chassis.
These errors basically indicate that the power supply in slot 0 had failed but
later
recovered by itself
Please make sure you are adhering to the following guidelines
Follow proper safety and grounding guidelines,
verify the installation of the PEM and confirm that the hardware is fully
seated and properly screwed in
Verify that power is connected and turned on. Verify that the PEM is turned on.
For proactive reason you can get the RMA and have the part onsite as spare and replace it if you see the logs pouring after 24 hours.
HTH
