Connecting the Cables
To connect the drive to the computer, you’ll attach it to two
cables: a power supply cable and a drive ribbon cable. Follow
these steps to connect the cables:
1. If the subassembly is out of the computer, follow the steps
in Chapter 2 to replace it.
2. Locate one power supply cable for each drive you installed
in the internal drive bay. (The five cables may be secured in
the clasps on the side of the subassembly.) You can use any
of the free cables labeled P1 through
P5.
3. Position the cable connector so its notched comers line up
with the notched comers of the power supply socket on
your drive, as shown below. Make sure the holes fit over all
the pins and then push in the connector.

Caution
If you do not align the connector correctly, you could
severely damage your drive when you push it in.
