Bug Id
<SUNBUG: 6599898>

Date of Preliminary Release
24-Sep-2007

Date of Resolved Release
06-Feb-2008

A customer or Field Engineer will replace the wrong DIMM if the DIMM Locator Label is used on a Netra T2000 system shipped prior to January 24, 2008 (see full details below).

Impact

A customer or Field Engineer will replace the wrong DIMM if the DIMM Locator Label is used on a Netra T2000 system shipped prior to January 24, 2008.

This will only be seen when debugging a DIMM issue using Sun's POST in conjunction with the DIMM Locator Label.

Contributing Factors

The incorrect label is documented in the Identification of Affected Parts section of this asset.

Sun Fire T2000 Servers are NOT impacted by this issue and currently have the proper DIMM Locator Label.

Symptoms

No initial symptoms. However, replacing the wrong DIMM will lead to additional troubleshooting time.

Root Cause

The DIMM Locator Label on the Netra T2000 was marked improperly during initial release. This label issue was corrected in systems manufactured after January 24, 2008 and as of Serial Number 0802FMP00R via ECO# WO_37812.

Workaround

Review the Netra T2000 Server Service Manual (819-5841-10 or later) Chapter 4.4 (Replacing a DIMM) prior to replacement of DIMMs on existing systems. Systems manufactured after ECO WO_37812 cut-in (which occured on January 24, 2008) will have a corrected DIMM Locator Label.

Identification of Affected Parts (how to):

Erroneous DIMM locators will differ from the Service Manual, as follows:

       819-5841-10         Erroneous DIMM

C2/R0/D1(J1701)        C3/R0/D1
C2/R1/D1(J1901)        C3/R1/D1

Notice that the Rank and DIMM numbers are incorrect for channels 0 and 1. Also notice that channels 2 and 3 are reversed.

Resolution

Netra T2000 systems manufactured after January 24, 2008 and having a serial number of 0802FMP00R or later will not have this issue. For Netra T2000s shipped prior to this should use the workaround above.
