Locating internal drives
Internal drives are devices that your computer uses to read and store data. You can add drives to your
computer to increase storage capacity and enable your computer to read other types of media. Internal
drives are installed in bays. In this manual, the bays are referred to as bay 1, bay 2, and so on.
When installing or replacing an internal drive, it is important to note the type and size of the drive that you
can install or replace in each bay and correctly connect the cables to the drive installed. Refer to the
appropriate section in Chapter 9 “Replacing FRUs (Machine Types: 0889, 5023, and 7844.)” on page 97 for
instructions on how to install or replace internal drives for your computer.
Figure 5 “Drive bay locations” on page 71 shows the locations of the drive bays in your computer.
