Removing and replacing Gen2 and Gen2+ control enclosure parts
You can remove and replace customer-replaceable units (CRUs) in the control enclosure.
Each replaceable unit has its own removal procedure. Sometimes you can find that a step within a procedure might refer you to a different remove and replace procedure. You might want to complete the new procedure before you continue with the first procedure that you started.
Remove or replace parts only when you are directed to do so.
Be careful when you are replacing the hardware components that are located in the back of the system. Do not inadvertently disturb or remove any cables that you are not instructed to remove.
