Component Serviceability Requirements

System components are hot-serviceable, warm-serviceable, or cold-serviceable components, and are customer-replaceable units (CRUs) or field-replaceable units (FRUs). See Preparing the Server for Component Replacement.

  • Hot service components can be serviced while the server chassis is powered on and running in Main power mode.

    Hot-serviceable components are also warm-serviceable, or cold-serviceable.

  • Warm service components can be serviced while the server chassis is in Standby power mode. You can remove and replace CMODs, and CMOD internal components such as DIMMs, processors, and heatsinks without disconnecting the back panel power cords or shutting down Oracle ILOM.

    Warm-serviceable components are also cold-serviceable.

  • Cold service components must be serviced when the server chassis is completely powered off and all four AC power cords are disconnected from the server back panel AC power block.

A CRU or FRU designation determines who is qualified to service a component.

  • Customer-replaceable units (CRUs) can be serviced by customers.

  • Field-replaceable units (FRUs) must be serviced by qualified Oracle Service personnel.
