PROBLEM DESCRIPTION:     

SC2000 will fail Power-On Self-Test (POST) in extended mode with FDDI 5.0
SBus controllers installed with an unexpected data_access_exception error
which could cause the system to Watchdog Reset.

An example of this error is;
   
   0A>C0 XPT Test
   0A>    C_0 BW,IOC
   0A>    XPT Read Write Test
   0A>TEST FAILED - C0 XPT.XPT Read Write ID 36.2 LED 0x24
   0A>Data Compare Error
           address  = 0200FFBC
           expected = FFFFFFFF
           observed = 00000000

During a Power-On Self-Test (POST), the SC2000 platform is unable to
make bus accesses.  It was found that the SC2000, and possibly the
SS1000, hold the SBus in a reset mode while the host accesses the bus.
The FDDI adapter drives some bus signals during this time, causing
conflicts on the bus.  THIS FAILURE MODE HAS NOT BEEN EXPERIENCED ON
ANY OTHER PLATFORM OTHER THAN THE SC2000.

The fix, new firmware for the FDDI 5.0 DAS/SAS cards, was released on
March 16, 1999 via ECO# WO_14662 which allows Enterprise Services to dash
roll both the 370-3142 and 370-3143 from -01 to -02.  This fix was made
available in Enterprise Services via LEAP 1043 released on July 16, 1999.
The LEAP allows the 370-3142-02 and 370-3143-02 to be reworked and
remarked as 370-4045-01 and 370-4046-01.

Manufacturing plans to begin shipping the 370-4045-01 and 370-4046-01
boards on January 1, 2000.

IMPLEMENTATION:

         ---
  	|   |  	MANDATORY (Fully Pro-Active)
	 ---    

         ---
  	|   | 	CONTROLLED PRO-ACTIVE (per Sun Geo Plan) 
	 ---   
			
         ---
        | X |   UPON FAILURE
	 ---
	

REPLACEMENT TIME ESTIMATE:   30 minutes

SPECIAL CONSIDERATIONS:

CORRECTIVE ACTION:
  
Upon failure replace as follows;

  370-2339-02 (or below) with 370-3142-02 or 370-4045-01
  370-2340-02 (or below) with 370-3143-02 or 370-4046-01
  370-3142-01 with 370-3142-02 or 370-4045-01
  370-3143-01 with 370-3143-02 or 370-4046-01
