7. Slide the existing drive out of the drive bay. Remove the drive from the drive
tray by gently pulling both sides of the drive tray outward until the mounting
pins are disengaged from the holes on the drive; then, lift the drive out of the
drive tray.
8. Touch the static-protective package containing the new drive to any unpainted
metal surface on the computer; then, remove the drive from the package and
place it on a static-protective surface.
9. Set any jumpers or switches on the new drive according to the documentation
that comes with the drive.
10. Attach the new drive to the drive tray. Place the drive on the drive tray and
align the holes on the drive with the mounting pins on the drive tray. Gently
pull both sides of the drive tray outward and insert the mounting pins into the
holes on the drive.
11. Slide the drive into the drive bay until the drive snaps into place.
12. Determine whether the new drive is a parallel IDE, serial ATA, or SCSI device;
then, connect one end of the appropriate signal cable into the back of the drive
and the other end of this cable into the appropriate parallel IDE, serial ATA, or
SCSI connector on the system board. See "Power and signal cables for
internal drives" for additional information about cabling drives and
"System-board internal connectors" on page 24 for the location of parallel IDE,
serial ATA, and SCSI connectors on the system board. If there are open
connectors on the cables connecting existing parallel IDE, serial ATA, or SCSI
drives, these cables can be used to connect the new drive.
13. Route the signal cable so that it does not block the airflow to the rear of the
drives or over the microprocessor.
14. Connect the power cable to the back of the drive. The connectors are keyed
and can be inserted only one way.
15. Push the drive cage outward, and press in on the drive-cage release tab; then,
rotate the drive cage back into the computer.
16. 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 27) and then go to "Completing the installation" on page 40.
Power and signal cables for internal drives: Your computer uses cables to
connect parallel IDE, serial ATA, and SCSI devices to the power supply and to the
system board. (See "System-board internal connectors" on page 24 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.
v When you install a drive, ensure 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.
v If you have only one IDE device on a cable, it must be set as a primary device.
v If two IDE devices are used on a single cable, one must be designated as the
master device and the other as the subordinate device; otherwise, the computer
might not recognize some of the IDE devices. The master (primary) and
(subordinate (secondary) designation is determined by switch or jumper settings
on each IDE device.
v If two IDE devices are on a single cable, and only one is a hard disk drive, the
hard disk drive must be set as a master device.
