Notes

  1. Set SW1 to BAT when the board is installed. Software will not initialize Prestoserve unless battery backup is enabled.
  2. Set SW1 to +5V when the board is removed and cache data does not need saving.
  3. Cache is cleared when SW1 is set to +5V for more than five minutes.
  4. Do NOT accelerate the root file system.
  5. Install Patch 101714-01 for Prestoserve 2.4 and 2.4.1, or 103043-08 for Prestoserve 2.4.2.
  6. The Prestoserve hardware design is not compatible with 64-bit DVMA. Disable 64-bit DVMA when Prestoserve is used with Ultra 1 Model 170E, Ultra 2, and SunSwift. Refer to BugID 1224649. Add the following to /etc/system:
    set fas:fas_enable_sbus64 = 0
  7. Only 32-bit drivers are provided by the Prestoserve software, so if you are running Solaris 7, you must boot in 32-bit mode for the Prestoserve drivers to load.
