that the hot-swap redundant power supply is likely to fail or has failed. Reinstall the new hot-swap
redundant power supply to see if the problem can be solved. If the new hot-swap redundant power
supply still does not work correctly, contact your place of purchase or a service representative for help.

and use any packaging materials that are supplied to you for shipping.
