General Installation Guidelines
Connect hard drives to the connector labeled "SATA" and connect CD/DVD drives to the connector labeled "IDE".
Serial ATA hard drives should be connected to the connector labeled SATA on the system board. IDE CD/DVD drives should be connected to the connector labeled IDE.
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 primary or the boot device (drive 0), and the device attached to the middle connector on the interface cable is the secondary device (drive 1). See the drive documentation in your upgrade kit for information on configuring devices for the cable select setting.
Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive and to the system board. Some CD/DVD drives may also have an audio connector; one end of the audio cable will attach to the drive connector and the other will attach to the system board.

Most 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.
When connecting an IDE cable, ensure you align the colored stripe with the pin 1 connector. When disconnecting an IDE cable, grasp the colored pull tab and pull until the connector detaches.
When connecting and disconnecting a serial ATA cable, hold the cable by the connector at each end.
NOTE: The system board serial ATA connector may have an attached cover or shroud.

SCSI Device Installation Guidelines
This section describes how to configure and install SCSI devices in your computer.
NOTE: The system board SCSI controller supports hard drives only. Do not connect CD or DVD drives,
tape drives, DAT drives, and so on.
SCSI ID Numbers
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:
System Board Controller
Controller Card
Device
ID
Device
ID
Controller
7
Controller
7
Boot hard drive
0
Boot hard drive
0
CD or DVD drive
5
tape or DAT drive
6
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.
Device Termination
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.
General Guidelines
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 IDE hard drives are installed.
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.
SCSI Cables
Ultra 320 (optional on the Dell Precision 370 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.
Hard Drive
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product 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.
Removing a Hard Drive
If you are replacing a hard drive that contains data you want to keep, back up your files before
you begin this procedure.
Disconnect the power and hard-drive cables from the drive.

Installing a Hard Drive
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).
