8. Connect a DC power cable to the power input connector on the back of the drive (see Figure 4).

   Check all connectors to be certain that they are properly cabled and firmly seated.

9. Connect one of the device connectors on the EIDE cable to the 40-pin interface connector on the back of the hard-disk drive.

NOTICE: You must match the colored strip on the EIDE cable with pin 1 on the drive's interface connector to avoid possible damage to your system.

NOTE: Ultra Advanced Technology Attachment (ATA)/66 hard-disk drives require an 80-conductor cable to transfer data at full speed. The 80-conductor cable has a 40-pin connector just like the Ultra ATA/33 cable but has twice as many wires within the cable itself. If you use an Ultra ATA/33 cable with Ultra ATA/66 hard-disk drives, the drives will transfer data at Ultra ATA/33 speeds.

This section describes how to configure and install small computer system interface (SCSI) devices in your system.

SCSI Configuration Guidelines

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, refer to the documentation for your SCSI devices and/or your host adapter card. The following subsections offer some general guidelines.

NOTE: Dell does not support mixing SCSI and EIDE hard-disk drives in the same system. If your system contains any EIDE hard-disk drives, do not install SCSI hard-disk drives.

SCSI ID Numbers

Internal SCSI devices must have a unique SCSI ID number from 0 to 15.

When SCSI devices are shipped from Dell, the default SCSI ID numbers for the primary and secondary controllers are assigned as follows:

• SCSI controller: SCSI ID 7
  
  
• Boot SCSI hard-disk drive: SCSI ID 0
  
  
• SCSI CD-ROM drive: SCSI ID 5
  
  
• SCSI tape or digital audio tape (DAT) drive: SCSI ID 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.

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, refer to 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. SCSI cables purchased elsewhere are not guaranteed to work with Dell systems.

Device Termination

SCSI logic requires that either:

• Termination be enabled for the two devices at opposite ends of the SCSI chain and disabled for all devices in between.
  
  
• Termination be enabled at the ends of the cable and disabled on all devices in the chain.

Dell recommends 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.

SCSI Cables

Ultra 160/m low-voltage differential (LVD) devices (hard-disk drives) use a 68-pin cable. One end of this cable should be attached to the SCSI controller connector. The remaining connectors on the cable should be attached to the various LVD devices.

Narrow SCSI devices (tape drives, CD-ROM drives, and some hard-disk drives) use a 50-pin cable. One end of this cable should be attached to the SCSI controller connector. The remaining connectors on the cable should be attached to the various Narrow SCSI devices.

General Procedure for Installing SCSI Devices

Configure and install one or more SCSI devices in your computer as follows:

1. Determine which connector on the internal SCSI cable you will attach to each SCSI device.
   
   
2. Unpack each SCSI device and prepare it for installation.

NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer.

NOTICE: When you unpack the drive, do not set it on a hard surface, which may damage the drive. Instead, set the drive on a surface such as a foam pad that will sufficiently cushion it.

Configure the device for a SCSI ID number and disable termination, if necessary.

3. Install the SCSI devices as appropriate.

• To install a SCSI hard-disk drive, complete steps 3 through 7 of "Installing an EIDE Hard-Disk Drive in the Mini Tower Chassis" or "Installing an EIDE Hard-Disk Drive in the Desktop Chassis." Then continue with step 4 of this procedure.
  
  
• To install a SCSI tape drive, CD-ROM drive, or DAT drive, complete steps 3 through 7 of "Installing a Diskette, LS-120 SuperDisk, Tape, or CD-ROM Drive in a Mini Tower Chassis" or steps 3 through 6 of "Installing a Diskette, LS-120 SuperDisk, Tape, or CD-ROM Drive in a Desktop Chassis." Then continue with step 4 of this procedure.
  
  
• To install an external SCSI device, continue with step 4 of this procedure.
  
  
• To install a SCSI host adapter card, configure the card and install it in an empty expansion slot (see "Installing an Expansion Card"). If you attach any SCSI hard-disk drives to the host adapter card, connect the hard-disk drive access cable to the SCSI host adapter card and to the auxiliary hard-disk drive light-emitting diode (LED) connector on the system board (see Figure 1 in "Installing System Board Options").
  

4. Attach the SCSI cable to each SCSI device.

NOTICE: You must match the colored strip on the cable with pin 1 on the drive's interface connector to avoid possible damage to your system.

The connectors on Narrow SCSI cables are keyed for proper positioning—a raised area on the outside of the header connector fits into a notch on the device connector. The connectors on LVD SCSI cables are shaped so that they can be attached one way only.

If you are installing an external SCSI device, connect one end of the external SCSI cable to the SCSI bus connector on the back of the device. Attach the other end of the external SCSI cable to the SCSI connector on the system back panel.

5. Connect the SCSI device(s) to power.

• If you are installing an internal SCSI device, connect a DC power cable to the power input connector on the SCSI device.
  
  
• If you are installing an external SCSI device, connect the socket end of the power cable into the AC power receptacle on the back of the SCSI device. Connect the other end of the power cable into a standard electrical wall outlet.

Check all other cable connections. Fold all internal cables out of the way to provide airflow for the fan or cooling vents.

6. If you installed an externally accessible device, remove the front-panel insert for the drive bay.

For a mini tower chassis, you must first remove the front bezel as described in "Removing and Replacing the Front Bezel (Mini Tower Chassis Only)." To remove a front-panel insert, hold the bezel (mini tower chassis) or computer cover (desktop chassis) with the inside facing toward you and press each end of the insert with your thumbs until it snaps free of the bezel.

7. Replace the computer cover. Then reconnect your computer and peripherals to their power sources, and turn them on.
   
   

	NOTE: After you remove and replace the cover, the chassis intrusion detector will cause the following message to be displayed at the next system start-up:
	ALERT! Cover was previously removed.

8. To reset the chassis intrusion detector, enter System Setup and reset Chassis Intrusion to Enabled or Enabled-Silent.

See "Chassis Intrusion" for instructions.

NOTE: If a setup password has been assigned by someone else, contact your network administrator for information on resetting the chassis intrusion detector.

9. If necessary, update the drive system configuration information in System Setup.

After installing a SCSI hard-disk drive, Primary Drive 0 and Primary Drive 1 should be set to None. If you have any EIDE devices on the second EIDE channel, such as a CD-ROM or tape drive, Secondary Drive 0 and/or Secondary Drive 1 should be set to Auto. If you have any SCSI devices on the second SCSI channel, Secondary Drive 0 and/or Secondary Drive 1 should be set to None.

10. If you installed a SCSI hard-disk drive, partition and format the drive. Then install the operating system.

For instructions, see "Partitioning and Formatting SCSI Hard-Disk Drives" and your operating system documentation.

11. Test the SCSI devices.

Test a SCSI hard-disk drive by running the Dell Diagnostics.

To test a SCSI tape drive, refer to the documentation for the tape drive software to perform a tape drive backup and verification test.

Partitioning and Formatting SCSI Hard-Disk Drives

You may need to use different programs than those provided with the operating system to partition and format SCSI hard-disk drives. Refer to the documentation that came with your SCSI software drivers for information on installing the appropriate drivers and preparing your SCSI hard-disk drive for use.
