Solution 1020847.1 : Netra T5220 Servers shipped containing DIMMs misprogrammed with wrong part number.

Impact

If the programmed electronic part number is used, the wrong replacement part will be ordered. The DIMM's physical label is correctly marked. There is no other operational impact due to this issue.

Contributing Factors

This issue affects Netra T5220 Servers manufactured between January and August of 2009.

Netra T5220 Servers with chassis serial numbers between 0901FMxxxx and 0932FMxxxx may be impacted by this issue as shipped from Sun Manufacturing. Other platforms that support this DIMM are not impacted. DIMM spares are not impacted as they were programmed elsewhere.

Symptoms

Early 1.8V DIMMs (Sun P/N 371-2144-01) were mis-programmed as EOLed 1.8V DIMMs (Sun P/N 371-2143-02).

This incorrect information can be seen in the following ILOM example:

-> show /SYS/MB/CMP0/BR0/CH0/D0

/SYS/MB/CMP0/BR0/CH0/D0
   Targets:
       SEEPROM
       SERVICE
       PRSNT
       T_AMB

   Properties:
       type = DIMM
       component_state = Enabled
       fru_name = 2048MB DDR2 SDRAM FB-DIMM 333 (PC2 5300)
       fru_description = FBDIMM 2048 Mbyte
       fru_manufacturer = Micron Technology
       fru_version = FFFFFF
       fru_part_number = 371-2143-02 Rev 50    <----- *
       fru_serial_number = 002C080737E20D5313
       fault_state = OK
       clear_fault_action = (none)

   Commands:
       cd
       show

Affected systems were populated with the correct type of DIMMs and operate properly. Although both DIMM types are 1.8V, a mixture of these two DIMM types in the same system will cause the system to fail POST.

Root Cause

Manufacturing incorrectly programmed DIMMs prior shipment due to the supplier not changing the DIMM program after the switch over to a new part.

This issue only impacts the Netra T5220 Servers as shipped from Manufacturing as this misprogramming issue was confined to a specific Manufacturing location. DIMM spares are not impacted by this issue as their programming was done at a different location.

Manufacturing corrected this issue in July of 2009, so systems with correctly programmed DIMMs started shipping in August (exact date not available). Sun Services inventories (RSLs) were not purged as their is no impact to DIMM spares.

Corrective Action

Workaround:

See Resolution section below.

Resolution:

Use the DIMM part number located on the physical label when ordering replacement DIMMs and not the electronically programmed part number.

Comments

Per the Sun System Handbook, the 371-2144 is spared as 511-1161.
