PROBLEM DESCRIPTION:
Service diagnostic cables (F370-4119-01) for the StorEdge T3 Array
are miswired and may not work. The F370-4119-01 part is a serial
maintenance cable used to connect the T3 Array to a terminal or host
port connection and provide capability to diagnose complex failure
conditions.
This problem will impact all field service engineers who have T3
diagnostic cables in their possession. Some diagnostic cables
(F370-4119-01) may be miswired and will not function properly. These
affected cables were distributed worldwide. The approximate number
of distributed cables in each geo are: 60 in Americas, 50 in APAC,
and 50 in EMEA.
Root cause was determined to be improper assembly of the cables at
the supply vendor. The connectors on these cables are mis-wired, or
mis-oriented which causes the cable to function improperly. This
could lead to improper diagnosis of problems with customer T3 disk
arrays.
It is believed that diagnostic cables at all of Sun's Regional Stock
Locations (RSLs) have been purged. All cables are accounted for except
for those in the hands of SMI field personnel. Since it is not cost
effective to return the cables for re-work, all suspect cables should
be scrapped and replacement cables ordered.
IMPLEMENTATION:
---
| | MANDATORY (Fully Pro-Active)
---
---
| | CONTROLLED PRO-ACTIVE (per Sun Geo Plan)
---
---
| X | REACTIVE (As Required)
---
CORRECTIVE ACTION:
The following recommendation is provided as a guideline for authorized
Enterprise Service Field Representatives who may be encountering the
above mentioned problem.
The mis-wired diagnostic cables are not distinguishable from good cables
by external visual inspection. They cannot be isolated by dash-roll or
date of manufacture. Therefore, current diagnostic cables outside of
their original FRU packaging must be checked for proper wiring or thrown
away, and replacement diagnostic cable kits (F370-4119-01) ordered. Refer
to the below wiring diagram in order to check for proper wiring. If a
cable is still inside it's original FRU packaging look for a red "QA"
stamp
on the packaging near the part number label. If this stamp is present the
cable can be considered good and should not be scrapped.
If the cable is not in it's original FRU packaging, or the "QA" stamp
is
not on the FRU packaging, open the cable connector hoods at each end and
check the wiring against the below diagram. If the wiring is different
than the diagram the cable should be considered bad, scrapped and a
replacement cable ordered via normal supply channels.

| Correct wiring for T3 RJ11 |
|=====================================|
| 25 pin connector | 9 pin connector |
|___________________|_________________|
| pin 2 - yellow | pin 2 - blue |
| pin 3 - blue | pin 3 - yellow |
| pin 7 - white | pin 5 - white |
|___________________|_________________|
Once the replacement cable is received notice that there should be a
"QA"
stamp on the FRU packaging near the part number label.

Implementation Footnote:
i) In case of MANDATORY FINs, Enterprise Services will attempt to
contact all affected customers to recommend implementation of
the FIN.
ii) For CONTROLLED PROACTIVE FINs, Enterprise Services mission critical
support teams will recommend implementation of the FIN (to their
respective accounts), at the convenience of the customer.
iii) For REACTIVE FINs, Enterprise Services will implement the FIN as the
need arises.
