Reassembly

1If installing a replacement hard drive, transfer the following:

hard drive bracket

2 T10 bracket screws

922-9136

2 T10 screw pins

922-7001

2Note: Each hard drive vendor has a unique sensor cable. Do not mix and match temp sensor cables.

3Important: When installing a Western Digital drive:

orient drive with circuit board facing up (as shown)

connect temp sensor cable to hard drive pins, leaving 2 left pins unconnected and the gray wire on sensor cable installed in the “up” orientation.

If sensor cable is installed incorrectly the hard drive fan will run at full speed.
