Removing an expansion unit

Learn about removing an expansion unit from a system unit concurrently or nonconcurrently.

You can remove expansion units from a system with the system powered on and running (concurrently), or with the system powered off (nonconcurrently), depending on your situation.

Note: If you are removing a 5791 (5797/5798), 5803, or 5873 expansion unit from an IBM® Power 595, you do not use this procedure. You must use the remove enclosure task in the HMC. To do this, select Serviceability > Hardware > Remove Enclosure for the managed system from which the expansion unit is being removed.
