Notes

  1. The minimum operating system is Solaris 8 4/01.
  2. System Controller slots are labeled SCC0 and SCC1.
  3. Pressing the Reset switch reloads the System Controller software (attempting a SC reboot first is recommended).
  4. Resetting the System Controller with OBP >/=5.12 can bring down running domains if the System Controller is performing a JTAG operation.
  5. Shut down running domains before resetting the System Controller.
  6. A System Controller reboot does not affect running domains.
  7. InfoDoc 42950 provides a "ftp-only" shortcut for updating the flashprom firmware.
