Run Extended uBoot on the Blade SP

Follow these steps to run the extened uBoot test on the blade SP.

Caution

Extended uBoot is intended for use by Sun Field Service and Manufacturing personnel.

What to Do

  1. Attach a console directly to the serial port on the blade.

    You must be monitoring uBoot output to switch from default to extended uBoot.

  2. Power-cycle or reset the blade to restart uBoot diagnostics.

    The blade's green OK LED blinks slowly as uBoot executes; the uBoot output is sent directly to the serial port.

  3. Watch for the following prompt to appear in the uBoot output:

    Enter Diagnostics Mode ['q'uick/'n'ormal (default)/e'x'tended]...

  4. Type x at this prompt to switch to extended uBoot.

    Extended uBoot will be executed for this boot only. The next time the SP is powered on or reset, default uBoot diagnostics will run.
