H165582:  SP MAY ISSUE OVER VOLTAGE ALERT DUE TO PS COMPATIBILITY


 SYMPTOM:

 The System Error Light will indicate a system failure.

 PROBLEM ISOLATION AIDS:

 - The system is a Netfinity 5000 server, Type 8659, any Model.

 - The system is configured with a Power Supply, FRU p/n01K9864.

 FIX:

 A new 175 Watt Power Supply (PS) upgrade FRU p/n36L8845
 replaces FRU p/n01K9864.

 WORKAROUND:

 When a Magnetek 350 watt PS and an older 175 watt upgrade PS is
 installed the service processor may issue an over voltage
 alert. Replace 175 watt PS FRU p/n01K9864 with FRU p/n36L8845.
 The over voltage alert can be verified by examining the system
 error log.

 DETAILS:

 When adding a older Delta upgrade power supply to a system with
 an existing Magnetek base power supply the shared common node
 may present an over voltage condition to the service processor
 due to a peak voltage detection problem. The shared common node
 circuitry has been modified in the newer upgrade power supply
 to eliminate this problem. Magnetek power supply will be listed
 as MAGN in the system card data in the system information menu
 of the configuration/set-up utility. There is no problem if the
 base power supply vendor is Delta.  Delta is listed as DELT in
 the system card data.
