Online and Standalone Diagnostics are used to diagnose your hardware. Online Diagnostics are optionally installed with the AIX operating system and can be run in concurrent or service mode. Standalone Diagnostics are stored on removable media. They can be run in service mode or if stored on CD-ROM mounted and run concurrently.
Some system types do not have an operator panel display or a mode switch. Some system types do not support Online and Standalone Diagnostics. If needed, refer to your system guides to determine what your system supports and how to load the diagnostics in service mode. If your system does not support Online and Standalone Diagnostics, then refer to the system guides to do diagnostics.

Some system cabling changes (such as installing wrap plugs or removing a device from the configuration) may require action by the operator of the attached system before you make the cabling changes on your system.
