H135078 - ECA007, PC SERVER 320 POWER SUPPLY REPLACEMENT PURPOSE: This ECA provides for the replacement of the power supply in eligible PC Server 320 systems. The new power supply prevents an over-voltage condition at power-on that may cause damage to the system components. This ECA expires November 30, 1997. FEATURES: Type, Machines Affected Model, With and/or Feature/Device B/M to be Service System Stage B/M Description Installed Hours Hours 8640 B/M0000000 PC SERVER 320 MFG. B/M0000000 00.8 00.6 BEFORE 10/1/96 (MFG DATE: 610 AND EARLIER) PHYSICAL CHECK: There is a S/N list of PC Server 320s with the suspect power supply. The list has both the system S/N and the bar code of the power supply that the system was built with. Before going on-site, call the Support Center or the HelpCenter to determine if the PC Server 320 is on the suspect list. Systems manufactured after October 1, 1996 (MFG DATE: 610 and later on the rear serial number label) are NOT affected. A good power supply has a SQUARE fan grill (FRU p/n71G0044 and IBM p/n71G0662) OR a ROUND fan grill (IBM p/n76H4079). Do not replace these power supplies. The suspect power supply has a ROUND fan grill (IBM p/n06H9111). Replace this power supply with FRU p/n71G0044.

If the serial number matches one on the list, then order the power supply FRU p/n71G0044. Once on-site, inspect the power supply to determine if it needs replacement. The FRU p/n71G0044 comes with a power switch attached to the power supply. When installing this FRU, remove the power switch (mounted internally with a screw) from the Server. NOTES: If the Server is up and running, then the components are NOT at risk unless the power cord is unplugged and then reconnected. System components may be damaged over time if the suspect power supply is not replaced and the power cord is unplugged and reconnected. This ECA expires November 30, 1997.
