PROBLEM DESCRIPTION:
On early shipments of E10000 systems (ONLY those shipped prior to August
15, 1997), some System Boards may experience early life failures causing
domain crashes.
Systems with multiple board domains will reboot with the failing board
removed from the configuration.
Repair analysis has attributed these failures to a DC-DC converter (power
puck) component that is mounted on the system board. Vendor analysis has
determined that failures are because of early life defects (cracked input
capacitors).
Manufacturing corrective actions were cut-in on August 15, 1997 to screen
out the affected power puck component. Consequently E10000 shipments
after that date will not experience this failure mode. SunService
Logistics stock of suspect system boards is being purged to ensure that
system boards supplied from spares inventory are free of the suspect
puck component.
Due to the early life nature of this failure mode most of the boards that
would fail already have. Of the remaining suspect system boards 1.2% may
still be subject to failure. All other power pucks will follow a normal
1,000,000 hour MTBF curve.
It is specifically recommended that this FCO be an "Upon Failure" FCO
for the following reasons:
i) There is a greater risk of creating system down time while trying to
proactively swap multiple system boards.
ii) For systems shipped before Aug/15/97, most of the boards that would
fail already have.
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
a) 501-4347-08 or 501-4347-09 with 501-4347-10
or b) 501-4786-01 with 501-4786-02
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, SunService will attempt to contact all known
customers to recommend the part upgrade.
ii) For controlled proactive swap FCOs, SunService mission critical support
teams will initiate proactive swap efforts for their respective accounts,
as required.
iii) For Replace upon Failure FCOs, SunService partners will implement the
necessary corrective actions as and when they are required.
