Using the OpenBoot PROM FCode
Self-Test
The Sun Quad FastEthernet adapter's self-test verifies the correct operation of the
adapter and identifies any hardware problems with the adapter. The self-test is a
suite of tests that reside in the adapter's FCode PROM.
You can only invoke the FCode selftest diagnostics using the OpenBoot PROM test
or test-all commands. In order to access the OpenBoot PROM, you must shut
down and halt your system to display the ok prompt.
You can use the adapter's self-test any time you want to determine the status of the
hardware. If you encounter an error while running the diagnostic test, the self-test
will display appropriate error messages.
Note – Although the self-test does not require the adapter's interface to be
connected to an active network, you will see failing error messages if it is not
connected.

To Run the FCode Self-Test Diagnostic

For more information about the OpenBoot commands (including test) in this
section, refer to the OpenBoot Command Reference manual.
1. Before shutting down the operating environment and halting the system, make
sure that all significant application and network activity on the server has
stopped.
2. Follow the appropriate procedures, as documented in the system's service manual,
to shut down and halt the system.
Refer to the system's documentation for the complete shutdown procedure.
After shutting down the system, you should see the OpenBoot PROMs ok prompt
on the system console.
3. At the ok prompt, set the auto-boot? configuration variable to false.
ok setenv auto-boot? false
