Using the selftest Diagnostics

The following tests are available to help identify problems when the system containing the Sun FastEthernet PCI Adapter does not boot.

The FCode selftest is added to the device tree during the probing phase of the OpenBoot PROM start-up sequence. You can invoke the FCode selftest diagnostics by using the OpenBoot user interface test or test-allcommands. If you encounter an error while running the diagnostics, appropriate messages will be displayed. Refer to the OpenBoot 3.x Command Reference Manual for more information on the test and test-allcommands.

selftest exercises most functionality of the adapter sub-section by sub-section and checks for the following conditions:

■Isolates faulty FRUs

■Checks, with a high confidence, that no hardware fault exists on No Trouble Found (NTF)

■Checks connectivity during adapter card installation

■Verifies that all components are functional
