  1. The 3.5V batteries are not field replaceable.
  2. Set SW1 to BAT when the board is installed. Software will not initialize Prestoserve unless battery backup is enabled.
  3. Set SW1 to +5V when the board is removed and cache data does not need to be saved.
  4. Cache data is cleared from memory when SW1 is set to +5V for more than five minutes.

Application Notes

  1. Do NOT accelerate the root file system.
  2. SBus Prestoserve accelerates SBus and VMEbus disk controllers.
  3. The SS600MP supports one VMEbus or one SBus Prestoserve.
  4. The SS600MP minimum requirements are SunOS 4.1.2 and Prestoserve 2.3.
  5. Install Patch 101714-01Internet Link for Prestoserve 2.4 and 2.4.1.
  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
