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-all commands. 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-all commands.
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
