Recently there have been problems concerning the replacement of rear fans on the PowerWave and the PowerCenter. Customer have called in reporting that the fan that was sent to them as a replacement will not fit in the area available or to be more precise "the fan is too thick"

In the past, PowerWave and PowerCenter were shipped with a minitower(MT) and desktop(DT) case. These cases can be identified quickly by the flip-out HD bracket that is in the rear of the machine. These cases/chassis came with a rear fan that was 8x1.5x8 cm and we had a significant amount in stock with a part # of 81564. When Power switched to the NT case, the fan size changed to 8x2.5x8 but the part number remained the same (81564). This was not a problem at first because the Seagate Medalist was still be installed in the PowerCenter. The Medalist was a 1/3 height drive and short enough in length to allow the change in fan size. However, when we switched to the Seagate Hawk (larger drive) the large fan would no longer fit. Therefore whenever the customers would call in for a rear fan replacement, they were sent the wrong size fan because there were two types of fans with the same part number.

SOLUTION:
The solution to this problem has been two-fold. First, the thin version of 81564 has been assigned a different part number(1150-0007-00) and can be accessed correctly through the parts list in Maximizer. For PowerCenter and PowerWave send only the 1150-0007-00 fan (PREPPED FAN SUB-ASSY, THIN CPU/REAR ) as a replacement. The second part of the solution is to purge RMA of all 81564 so that only the 1150-0007-00 will be sent.
