Some Sun Fire, SPARC Enterprise, and Sun Storage Systems Using Power Supply Units Within a Certain Date Code Range May Experience a Thermal Event Upon PSU Failure

1. Impact

Power supplies within a certain Date Code range for some Sun Fire, SPARC Enterprise, and Sun Storage systems (as listed below) may be vulnerable to a thermal event upon PSU failure.

2. Contributing Factors

This issue can occur on the following platforms:

• Sun Fire X4240, X4250, X4440, X4450 Servers
  
• Sun SPARC Enterprise T5220/T5240 Servers
  
• Sun Storage 7110/7410
  

Affected Power Supply Unit (PSU) Sun part numbers for Sun Fire X4240, X4250, X4440, X4450 Servers and Sun Storage 7110/7410 are:


Affected Power Supply Unit (PSU) Sun part numbers for Sun Fire X4240, X4250, X4440, X4450 Servers and Sun SPARC Enterprise T5220/T5240 Servers are:


To determine the Date Code for the SPARC Enterprise T5220/T5240 Servers, a physical inspection of the PSU will be necessary. Since the PSUs in SPARC Enterprise T5220/T5240 Servers are N+1 redundant and hot-swappable, they can be removed one PSU at a time for visual inspection of the Serial Number bar code label on the PSU.

Sun bar code label example:


Above example PSU serial number: 19080DR-0828A70ADR represents date code 0828

To determine the power supply part number and date code for the Sun Fire systems listed above, use ipmitool(1m) 1.8.9.4 or later (available on the Sun "Tools and Drivers" CD):


The "Tools and Drivers" CD can be downloaded at http://www.sun.com/download/index.jsp?tab=2 under the appropriate product listing.

Note for the Sun Fire X4450: The system must have been upgraded from ELOM to ILOM in order to see the PSU info via ipmitool. Instructions for upgrading can be found in The ELOM-to-ILOM Migration Users Guide at

http://docs.sun.com/source/820-4930-12/

To determine the power supply part number and date code for the Sun Storage 7110/7410, connect to the Service Processor via ssh(1). Log in as root/appliance password, then enter "show /SYS/PS0" (or "show /SYS/PS1"). This will return the PSU information including the Serial Number and Date Code, as in the following example:

login: root

-> show /SYS/PS0

 /SYS/PS0
    Targets:
        PRSNT
        VINOK
        PWROK

    Properties:
        type = Power Supply
        fru_name = A217
        fru_manufacturer = POWER ONE
        fru_part_number = 300-1897-04
        fru_serial_number = 19080DR-0828A70ADR Affected date code: 0827 & 0828 = year 2008, week 27 and week 28
        ...

3. Symptoms

The system will lose power from the affected PSU (with subsequent loss of power redundancy if other PSU(s) are already offline). The system may shut down, and may be accompanied by a burning odor or smoke.

4. Workaround

There is no workaround for this issue. Please see the Resolution section below.

5. Resolution

This issue has since been corrected in the manufacturing process and is being addressed with a proactive service implementation plan. Please contact your Sun Service Representative for remediation procedures and additional details regarding this issue.
