Abstract: NETFINITY 3500: POWER SUPPLY may LATCH-OFF running 230VAC

SYMPTOM:

•  The System does not power up when the On/Off power switch is actuated.
•  Removal and re-attachment of the Power Cable may result in power up of the system when the  power switch is actuated.

PROBLEM ISOLATION AIDS:

•  The System is any model Netfinity 3500 server Type 8644 supplied with 230VAC power.
•  The System contains any of the following Power Supplies with the respective Barcode Header Codes:

        Power Supply FRU P/N         Header Code
           01K9866 ----------------J14SK or J15AJ
           01K9858 --------------------J14BG
           12J6001 ----------------J14HO or J14RS
        The Barcode label is located on the Power supply and lists
        a Header code as follows:
                          Barcode Label
         __________________________________________________
        | IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII  |
        |                                                  |
        | YYYYYxxxxxx        xxxxxxx                xxx    |
        |__________________________________________________|
         Y= Header Code (first 5 characters)
   

•  The System experiences one or both of the Symptoms described  (in the Symptoms Section of this document) in a frequent OR infrequent manner.

FIX:

IF the System meets all the criteria listed in the "Problem Isolation Aids" section of this document, replace the Power Supply with either of the following Power Supplies:

         FRU P/N 01K9866 (with Header Code J15D1)
         FRU P/N 01K9858 (with Header Code J15D0)


Note: The Netfinity 3500 server power supply is NOT a Customer Replaceable Unit (CRU), thus requiring replacement by a IBM Authorized Servicer.

Customers may contact their local Dealer or call:
1-800-IBM-SERVE for Service by a Authorized IBM Servicer.

DETAILS:

Recent ongoing testing at IBM has determined a limited quantity of Power Supplies used in the Netfinity 3500 server enter a "Latch-Off state when supplied with 230VAC resulting in the Power Supply not Powering-up the System when the Power On/Off switch is actuated. This may occur infrequently and is limited to power supplies that have Header Codes listed in the "Problem Isolation Aids" Section of this document.

World-Wide FRU stock has been purged of the suspect Power Supplies.

NOTE: Systems Powered with 120VAC are NOT affected.
