Connect the fan cable to the header on the Compact Services Card (CSC). Make sure that the
raised edge on the fan cable connector faces the plastic tab on the header. Refer to the previous
diagram for the location of the header.
Note: Do not force the cable.
The connector on the fan cable is designed to prevent the cable from being
inserted backwards. If the cable does not insert properly, check that the raised
edge on the fan cable connector faces the plastic tab on the header.
