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

Certain 440MHz and 450MHz UltraSPARC II Modules supported on Ultra 60/80,
Enterprise 220R/420R and Netra t platforms may experience early life
failures resulting in Red State Exception, Send Mondo Timeout and hard
hang errors.

A limited number of systems manufactured between November 01, 2001 and
November 22, 2002 may contain affected CPU modules.  The affected system
serial number range is between 144xxxxx and 246xxxxx.  The probability of
experiencing the described issue is considered low at < or = 4%.

The failures caused by this problem are not unique to this issue.  Failures
include EDP and WP panics, Red State Exception, Send Mondo Timeout panics,
machine hard hangs, and machine reboots.  Typically, after experiencing
such errors, the only means of rebooting the machine is by power cycling
it with the front power button or key switch.  To be sure that a failure
is related to this problem, the failure must be repeatable and, when data
is available, must always identify the same CPU module is at fault.  The
time between failures is typically two to five weeks.

Root cause determined that the socket used on the module has a 90 day
shelf-life.  Modules assembled with sockets less than 90 days old have
not experienced this problem.  Once assembled, socket aging is not an
issue.  All loose sockets in manufacturing and repair that were more
than 90 days old have been scrapped, and field spares have been purged
and reworked with good sockets.

Corrective action was implemented in manufacturing by purging and reworking
all modules with new sockets (less than 90 days old) via Worldwide Stopship
Purge P001-20085 on November 22, 2002.  Modules were then dash rolled via
ECO# WO_25557 as of December 17, 2002.  Corrective action was put in place
in Sun Services via DPCO 336 as of December 17, 2002.

Parts Affected: 

February 28th, 2005

Implementation: 

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

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

 ---
| X |   UPON FAILURE
 ---

Replacement Time Estimate: 

0.5 hours

Special Considerations: 

Due to material availability issues, APac will not be fully ready
to support this FCO until approximately March 12, 2003.  All other
geographies are ready upon release of this FCO.

Because this problem manifests itself as a common system failure,
care should be given to first using the Best Practices Guide to
help determine the exact failure mode.  The E420R Best Practices
Troubleshooting Guide can be located at the following URL;

 http://pts-americas.west/vsp/wgs/products/E420R/e420_troubleshooting_guide.pdf

Corrective Action: 

NOTE! This FCO does not authorize the proactive replacement of any hardware.
      For those customers who insist on having their modules proactively
      replaced, please address this through the CIC program.  Reference
      the following URL for more information;

      http://uscq.ebay/Process/cic.html

Upon repeat failure and unsuccessful attempts to correct the failure by
the above mentioned Best Practices, the failing module should be replaced.

Upon Failure replace as follows;

 - replace 501-6058-02 (or less) with 501-6058-03 (or above) or
   501-6058-02 (with DPCO 336 label), or 501-6071-02, or
   501-6071-01 (with DPCO 336 label)

 - replace 501-6071-01 with 501-6071-02 (or above) or with
   501-6071-01 (with DPCO 336 label)

 - replace 501-6209-02 (or less) with 501-6209-03 (or above) or
   501-6209-02 (with DPCO 336 label)
   
 - replace 501-5682-03 with 501-5682-04
 


Identification of Suspect Part
------------------------------

For Serial Numbers: 144xxxxx - 246xxxxx:

Systems manufacted between November 2001 and November 2002 may contain
potentially affected CPU modules.  The affected system serial number range is
144XXXXX through 246XXXXX.  (the first 3 digits reflect the year and week of
manufacture).

Locate the CPU module part number.  If it is 501-6071-01 or 501-6058-02 (or
earlier) and without a "DPCO 336" sticker, the system is possibly affected by
the described issue.  

If it is 501-6209-02 (or earlier), please locate the CPU module serial number.
If it is 0 through 1000 or 2000 through 3500, it may be affected.  If it is
1001-1999, or greater than 3500, it will not be affected.  To find the CPU
module serial number, look at the barcoded label on the CPU module.  There will
be a number above it, example 50162091300.  The last 4 digits (1300 in this
case) is the serial number.  In this example, 1300 is within the range of
modules that are not affected.


For Serial Numbers: 220xxxxx - 319xxxxx: 

Systems manufacted between May 2002 and May 2003 may contain potentially
affected CPU modules.  The affected system serial number range is 220XXXXX
through 319XXXXX.  (the first 3 digits reflect the year and week of
manufacture).

For CPU module part number 501-5682-03, please locate the CPU module serial
number.  If it is 103XXX and above, it may be affected.  To find the CPU module
serial number, look at the barcoded label on the CPU module.  There will be a
number above it, example 5015682106778.  The last 6 digits (106778 in this case)
is the serial number.  In this example, 106778 is greater than 103XXX and
therefore possibly affected.

Comments: 

Observed average system MTBF has decreased by approximately 500 hours
on systems containing affected 450MHz CPU modules manufactured between
November 02, 2001 and November 22, 2002.

It is important to note :

1.  These failures have been attributable to manufacture variability, not to 
the design of the CPU, module or the socket.

2.  The vast majority of sockets are still within design specification and will
function as expected.

Additional data that supports a bounded 90 day early life failure condition was
extracted from actual units returned from the field which had failed for a
socket related symptom.  In these cases modules were taken back through extended
system testing under varying corner conditions of temperature, voltage and
frequency margining.  Modules which failed for a socket contact related issue
showed a TTF averaging less then 38 days of continuous power on run time.

Sun has examined the socket subtier supplier process and imposed the
following changes:

1.  A tightened column height tolerance has been implemented on all new sockets
used in all Sun modules.  The contact column height tolerance has been changed
from .026-.035" to .029-.035" to insure a column height that provides optimum
ohmic contact under compression.

2.  Inspection/measurement points have been integrated into the socket
manufactured process flow to insure sockets are made to Sun's required
tolerances.

"Wholesale" replacement of modules has been shown to create potential for
mechanical contact failures and introduce instability into a already stable
system.

Billing Type: 

Warranty: Sun will provide parts at no charge under Warranty
           Service. On-Site Labor Rates are based on how the
           system was initially installed.

 Contract: Sun will provide parts at no charge. On-Site Labor Rates
           are based on the type of service contract.

 Non Contract: Sun will provide parts at no charge. Installation by
               Sun is available based on the On-Site Labor Rates
               defined in the Price List.

Implementation Footnote: 

________________________

i)   In case of Mandatory FCOs, Sun Services will attempt to contact
     all known customers to recommend the part upgrade.

ii)  For controlled proactive swap FCOs, Sun Services mission critical
     support teams will initiate proactive swap efforts for their respective
     accounts, as required.

iii) For Replace upon Failure FCOs, Sun Services partners will implement
