IBM PC300GL (Type 6561) - CPU fans installed backwards
Applicable to: World-Wide
TEXT:
A small number of IBM PC300GL Series 6561 systems manufactured in Research Triangle Park may contain a CPU cooling fan installed facing in the wrong direction.
Note that IBM PC300GL Series 6591 systems ARE NOT affected.
Based on inspection results, the suspect manufacturing date range is 3/19/98 to 3/24/98.
By model number, the suspect serial number ranges are as follows:
Machine Type - Model |
Serial Number Range |
6561-32U |
23NT883 - 23NX532 |
6561-34U |
23AAZ16 - 23ABN90 |
6561-34U |
23ABX41 - 23ADA84 |
6561-42U |
23GNG03 - 23GNR02 |
6561-50U |
23TXD00 - 23TXZ39 |
6561-53U |
23AAAL7 - 23AAHG8 |
6561-54U |
23BLTH0 - 23BLZP9 |
Some additional systems may fall outside of these ranges.
Failure symptoms that may be reported by customers can vary from a hung system to intermittent application errors to system shutdowns. Servicers should inspect the orientation of the CPU cooling fan before replacing any hardware when servicing these PC300GL 6561 systems.
In the correct position, the round vendor label on the center of the fan should face the CPU, or rear of the system. The top of the black fan housing also features a molded arrow that should point towards the CPU when in the correct position. In some systems, this arrow may be covered by a bar code label.
If failures persist after confirming the correct orientation of the CPU cooling fan, continue normal problem determination procedures to isolate the failing FRU or application.
