The order in which the interfaces appear and their respective number keys may be dif-
ferent than in the above example. Only interfaces that are configurable from Boot
ROM control are listed. Interfaces in the system unit that have switches to set their
configuration are not listed.
If the one of the following error messages appear in the display
Configure Mode Failed
Configuration EEPROM Failed
one or more of the following situations exists with the I/O Configuration Mode:
• All of the configurations have been set to default values.
• Some default and some changed values have been set.
• All the configurations have been set to their changed values. Some minor error
occurred that shouldn't affect the system unit's configuration.
When an error message appears, check your system unit's Boot Mode Selection and
I/O Configuration Mode selections and verify that they are correct for your application.
If an error message like the following appears in the mode line at the bottom, or the
Configuration EEPROM Failed
with the Boot ROM or its associated circuits probably exists.
