Figure 7-1. Drive Locations Inside the System

General Installation Guidelines

IDE Drive Installation Guidelines

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 drives 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.

SCSI Installation Guidelines

Although SCSI drives are installed in essentially the same way as other drives, their configuration requirements are different. To install and configure a SCSI drive, follow the guidelines in the following subsections.

NOTE: SCSI devices installed by Dell are configured correctly during the manufacturing process. You do not need to set the SCSI ID for these drives.

SCSI Interface Cables

SCSI interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the cable connects to pin 1 in the connectors on both ends. When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.

SCSI ID Numbers

Each drive attached to a SCSI controller must have a unique SCSI ID number from 0 to 15.

The SCSI hard drive from which the system boots is configured as SCSI ID 0.
If you install an additional SCSI drive or change your SCSI configuration, see the documentation for each SCSI drive for information on setting the appropriate SCSI ID number.

NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that drives be attached to the interface cable in order by ID number.

SCSI Device Termination

SCSI logic requires that termination be enabled for the two drives at opposite ends of the SCSI chain and disabled for all drives in between. For internal SCSI drives, termination is configured automatically. See the documentation provided with any optional SCSI drive you purchase for information on disabling termination.

Configuring the Boot Drive

The drive or device from which the system boots is determined by the boot order specified in the System Setup program. See "Using the System Setup Program" in your User's Guide. To boot the system from a hard drive or drive array, the drive(s) must be connected to the appropriate controller:

To boot from a SCSI hard drive, the drive must be connected to the optional SCSI controller card. See the documentation that accompanied the controller card.

After you open and close the cover, the chassis intrusion detector, if enabled, causes the following message to appear on the screen at the next computer start-up:

ALERT! Cover was previously removed.

Reset the chassis intrusion detector by changing Chassis Intrusion to Enabled or Enabled-Silent.

Front-Panel Inserts

If you are installing a new 5.25-inch drive, remove the front-panel inserts to allow external access to the drive. To gain access to the front-panel insert, you might need to remove a device.

CAUTION: Only trained service technicians are authorized to open the system cover and access any of the components inside the system. See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
Open the system. See "Opening the System" in "Troubleshooting Your System."
If applicable, remove a device. See the appropriate removal procedure.
Squeeze the insert tabs until the insert pops free of the front-panel cover. See Figure 7-2.

Figure 7-2. Removing Front-Panel Inserts

Hard Drives

Your system contains up to four SATA or SCSI non-hot-plug hard drives. The integrated SATA controller supports two SATA hard drives. If more than two SATA drives are installed, they must be connected to an optional SATA controller card. If your system contains SCSI hard drives, they must be connected to an optional SCSI controller card.

The fourth hard drive is installed in the 5.25-inch drive bay (see Figure 7-1) using an adapter. After installing the drive and adapter, the removing and installing procedures are the same as the other hard drives.

The basic steps for removing and installing SATA and SCSI hard drives are the same.
