When you install a drive, you connect two cables—a DC power cable and an interface cable—to the back of the drive and to the system board connector and system power supply.
NOTICE: If your system was purchased with a Serial ATA hard drive, the
system includes the newer style Serial ATA style power connector. If you are
adding a Serial ATA hard drive to a system that was not originally equipped
with one and the drive you are adding requires the new style Serial ATA power
connector, you may need to obtain a power adapter cable from Dell. If you need
a Serial ATA power adapter cable, contact Dell.
When you connect two IDE devices to a single IDE interface cable and configure them for the cable select setting, the device attached to the last connector on the interface cable is the primary (master) or boot device (drive 0), and the device attached to the middle connector on the interface cable is the secondary (slave) device (drive 1). See the drive documentation in your upgrade kit for information on configuring devices for the cable select setting.
Because cable select is the default setting, you do not need to set any additional drives as a primary or secondary drive.
Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the other connector. Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored stripe along one edge of the cable) goes to the pin-1 end of the connector. The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened "1" printed directly on the board or card.
When you connect an interface cable, do not place the colored stripe away from pin 1 of the connector. Reversing the cable prevents the drive from operating and could damage the controller, the drive, or both.
Internal SCSI devices must have a unique SCSI ID number from 0 to 15. If you are using the SCSI connector on the system board and a SCSI controller card installed in your computer, you have two separate SCSI buses operating. Each SCSI bus has a set of SCSI ID numbers from 0 to 15.
When SCSI devices are shipped from the factory, the default SCSI ID numbers are assigned as follows:
NOTE: There is no requirement that SCSI ID numbers be assigned sequentially
or that devices be attached to the cable in order by ID number. If two or more
devices use the same ID, your computer may hang during POST and in SCSI
BIOS.
SCSI devices installed by Dell are configured correctly during the manufacturing process. You do not need to set the SCSI ID for these SCSI devices.
If you attach additional optional SCSI devices, see the documentation for each device for information about setting the appropriate SCSI ID number.
NOTICE: Dell recommends that you use only SCSI cables purchased from
Dell. Cables purchased elsewhere are not guaranteed to work with Dell
computers.
SCSI logic requires that termination be enabled for the two devices at opposite ends of the SCSI chain and disabled for all devices in between.
It is recommended that you use terminated cables and that you disable termination on all devices. See the documentation provided with any optional SCSI device you purchase for information on disabling termination on the device.
Follow these general guidelines when installing SCSI devices in your computer:
Although you install SCSI devices essentially the same way as other devices, their configuration requirements are different. For details on configuring your particular SCSI subsystem, see the documentation for your SCSI devices and/or your host adapter card.
Configure the device for a SCSI ID number and disable termination, if necessary.
To use an external SCSI device, you must have a SCSI controller card installed in your computer. Connect one end of the external SCSI cable to the connector on the back of the SCSI device. Attach the other end of the external SCSI cable to the connector on the controller card installed in the computer.
After you install a SCSI hard drive, Primary Drive 0 and Primary Drive 1 should be set to None in system setup if no EIDE hard drives are installed. If you have any EIDE devices on the second EIDE channel, such as a CD or tape drive, Secondary Drive 0 and/or Secondary Drive 1 should be set to Auto.
You may need to use programs other than those provided with the operating system to partition and format SCSI hard drives. See the documentation that came with your SCSI software drivers for information on installing the appropriate drivers and preparing your SCSI hard drive for use.
Ultra 320 (optional on the desktop computer), Ultra 160/m and Ultra2/Wide LVD drives (typically hard drives) both use a 68-pin cable. One end of the cable attaches to the SCSI connector on the system board or the SCSI controller card installed in your computer. The remaining connectors on the cable attach to the various drives.
Narrow SCSI drives (tape drives, CD drives, and some hard drives) use a 50-pin cable. One end of this cable attaches to the SCSI controller card. The remaining connectors on the cable attach to the various Narrow SCSI devices.
NOTICE: Dell recommends that you use only SCSI cables purchased from
Dell. Cables purchased elsewhere are not guaranteed to work with Dell
computers.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the System Information Guide.
NOTICE: To avoid damage to the drive, do not set it on a hard surface.
Instead, set the drive on a surface, such as a foam pad, that will sufficiently
cushion it.
If you are replacing a hard drive that contains data you want to keep,
back up your files before you begin this procedure.
Shut down the computer through the Start menu.
Ensure that your computer and attached devices are turned off. If your
computer and attached devices did not automatically turn off when
you shut down your computer, turn them off now.

computer and then unplug it from the network wall jack.
Disconnect any telephone or telecommunication lines from the
computer.
Disconnect your computer and all attached devices from electrical
outlets, and then press the power button to ground the system board.
If you have installed a padlock through the padlock ring on the back
panel, remove the padlock.
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.
NOTICE: Before touching anything inside your computer, ground yourself by
touching an unpainted metal surface, such as the metal at the back of the
computer. While you work, periodically touch an unpainted metal surface to
dissipate any static electricity that could harm internal components.
Unpack the replacement hard drive, and prepare it for installation.
Check the documentation for the drive to verify that it is configured
for your computer.
If your replacement hard drive does not have the bracket rails
attached, remove the rails from the old drive by removing the two
screws that secure each rail to the drive. Attach the bracket rails to the
new drive by aligning the screw holes on the drive with the screw holes
on the bracket rails and then inserting and tightening all four screws
(two screws on each rail).
If the drive you just installed is the primary drive, install your
operating system on the hard drive.
