10. Slide the drive into the drive bay until the drive snaps into place.
11. Determine whether the drive is a Serial ATA or SCSI device; then, connect one
end of the applicable signal cable into the back of the drive and the other end
of this cable into the applicable Serial ATA or SCSI connector on the system
board. If there are open connectors on the cables connecting existing Serial
ATA or SCSI drives, these cables can be used to connect the new drive. See
"Power and signal cables for internal drives" for additional information about
cabling drives and "System-board internal connectors" on page 14 for the
location of Serial ATA and SCSI connectors on the system board.
12. Route the signal cable so that it does not block the airflow to the rear of the
drives or over any microprocessor.
13. Connect the power cable to the back of the drive. The connectors are keyed
and can be inserted only one way.
14. Push the drive cage outward, and press in on the drive-cage release tab.
Rotate the cage part-way into the computer; then, reconnect any power cables
you disconnected in step 5 and rotate the cage the rest of the way back into
the computer. Make sure that the drives and cables do not strike the
microprocessor fan sink.
15. If you have other options to install or remove, do so now; otherwise, replace
the support bracket (see "Removing and installing the support bracket" on
page 17) and then go to "Completing the installation" on page 40.
Power and signal cables for internal drives: Your computer uses cables to
connect IDE, Serial ATA, and SCSI devices to the power supply and to the system
board. (See "System-board internal connectors" on page 14 for the location of
system-board connectors.) Review the following information before connecting
power and signal cables to internal drives:
v The drives that are preinstalled in your computer come with power and signal
cables attached. If you replace any drives, remember which cable is attached to
which drive, or label the cables.
v When you install a drive, make sure that one of the drive connectors of the signal
cable is connected to the drive and that the connector at the other end of the
signal cable is connected to the system board.
