Component Serviceability

The replaceable components in your server are designated as either a customer-replaceable unit (CRU) or a field-replaceable unit (FRU).

• A part designated as a FRU must be replaced by an Oracle-qualified service technician.

• A part designated as a CRU can be replaced by a person who is not an Oracle-qualified service technician.

If the component can be serviced while the server is powered on, it is called a hot-service component. If the server has to be powered off before the component can be serviced, it is called a cold-service component.

The following table lists the components, their service designations, and their serviceability.
