You cannot mix power supply types within the chassis. If you are replacing a
2400 W power supply from an original system with a newer 2800 W power
supply, you must replace both power supplies and PDUs (see

notify the appropriate personnel that all routing traffic stops while the upgrade
takes place.
Set the power switch to the off (0) position.
