You prepare to replace a power supply in a 12-drive or 24-drive controller shelf or drive shelf by collecting support data about your storage array and locating the failed component. The power supply is referred to as a power-fan canister in ThinkSystem System Manager.
Before you begin
You can replace a power supply while your storage array is powered on and performing host I/O operations, as long as the second power supply in the shelf has an Optimal status and the OK to remove field in the Details area of the Recovery Guru in ThinkSystem System Manager displays Yes.
Go to Remove failed power supply.
