FASTRAM MEMORY BOARD FAILURES
|
||
|
|
|
||
|
|
|
||
|
|
PROBLEM: It has been reported that the AST FASTRAM memory board for the
|
||
|
|
Premium 286 may fail after a few years of successful
|
||
|
|
operation.
|
||
|
|
|
||
|
|
CAUSE: This is due to a possible defective capacitor located at one
|
||
|
|
or all of the following locations on the FASTRAM memory board;
|
||
|
|
C1-C3, C6, C11-C13, C20 and C34.
|
||
|
|
|
||
|
|
AFFECTED
|
||
|
|
SYSTEMS: AST FASTRAM Memory Boards with part number 202146-003 and
|
||
|
|
202146-004.
|
||
|
|
|
||
|
|
The suspect FASTRAM boards can be identified by the above part
|
||
|
|
number and by the capacitors. The capacitor is a cylinder 5
|
||
|
|
millimeters high and 5 millimeters in diameter. The color
|
||
|
|
scheme is dark blue with a light blue vertical stripe, except
|
||
|
|
for the top that is exposed aluminum metal.

||
|
|
|
||
