1 Introduction Overview HP Superdome 2 Onboard Administrator is the complex management processor, subsystem, and firmware base used to support HP Integrity Superdome 2 complexes and all the managed devices contained within the complex. Onboard Administrator provides a single point from which to perform basic management tasks for the following complex devices: • Compute enclosures • IOXs • Server blades • I/O interconnects Onboard Administrator performs configuration steps for the complex, enables run-time management and configuration of the complex components, and informs you of problems within the complex through email, SNMP, or the Insight Display. HP recommends that you read the HP Integrity Superdome 2 User Service Guide for complex specific information before proceeding with the Onboard Administrator setup. This user guide provides information on the following topics: • Initial setup and operation of the HP Superdome 2 Onboard Administrator • Use of the Onboard Administrator GUI • Use of the compute enclosure Insight Display • Initial setup and operation of the HP Superdome 2 Door Status Display The HP Integrity Superdome 2 Onboard Administrator Command Line Interface User Guide covers the use of the CLI. The HP Superdome 2 Onboard Administrator provides several features designed to simplify management of Superdome 2 enclosures, blades, and interconnects. Compute enclosures within a Superdome 2 complex can be configured with redundant Onboard Administrator modules to provide uninterrupted manageability of the entire complex in the event of a failure of a single Onboard Administrator module. The following table lists which Onboard Administrator feature is enhanced when an enclosure contains redundant Onboard Administrator modules. For an enclosure with only a single Onboard Administrator module, the table indicates the behavior of the enclosure if the single Onboard Administrator module has failed or is removed.
