PROBLEM DESCRIPTION :

Sunon fans used in the SunCobalt RaQ3 and RaQ4 products have proven to
have a high failure rate due to fans spinning intermittently, or not
at all.

Root cause analysis of the Sunon fans has not revealed a specific reason
for premature failure. Empirical data, and side-by-side testing with
replacement fans, have revealed superior performance and durability from
NMB and Delta fans, in comparison with the Sunon. As a result of this
testing Sun is no longer using the Sunon fans that were only released
under the -01 part number.

Corrective action was made available in manufacturing via ECO WO_23969
on May 15, 2002 by releasing part number 540-5309-02. Corrective action
was made available in Sun Services by issuing and LEAP 2056.A on
August 21, 2002,


PLANNED IMPLEMENTATION COMPLETION DATE: September 30, 2004

IMPLEMENTATION :

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

 ---
|   |   CONTROLLED PRO-ACTIVE (per Sun Geo Plan)

REPLACEMENT TIME ESTIMATE : .5 hours

SPECIAL CONSIDERATION :

CORRECTIVE ACTION :
