       1.0   Overview:  The OPM microcode changes between v7 and v8 are

             modify the thermal thresholds to avoid overtemp warnings at safe

             temperatures and improves handling of thermal alearts at sub-zero Celcius

             conditions.  It also enables support for a new microprocessor.


             1.1   Overview about this code


             1.2   Limitations



             1.3   Enhancements



             1.4   Level of Recommendations and Prerequisites for the

                   Update:


                   This update is only required if the customer receives and

                   is troubled over temperature warnings during normal operation or

                   if the module runs in sub-zero Celcius conditions.


             1.5   Dependencies:

                   - none



       2.0   Change History

       --------------------

             2.1  Optical Pass Thru Module (OPM) microcode

                   from version 7 to version 8 - modified how sub zero degree Celcius

                   conditions are managed, enabled support for a new microprocessor  and

                   modifed the thermal threshold for warning and shutdown from 50

                   and 65 degrees C respectively to 65 and 70 degrees C respectively.


       3.0   Installation and Setup Instructions

       -----------------------------------------



             3.1   This code is updated from the I/O module code update screen of

                   BladeCenter management module.



       4.0   Configuration Information

       -------------------------------


              4.1  - none - all configuration information is preserved.



       5.0   Unattended Mode

       -------------------------------

             The update does not support unattended installation directly from the firmware.  The

             management module unattended options should be applied.
