Dell Mini Tower System Partitioning and Formatting Scsi Hard-Disk Drives, Test the Scsi devices

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 wide 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.

7.Attach the SCSI cable to the connector on the SCSI host adapter card.

•If you are installing an internal SCSI device, connect the colored edge on the internal SCSI cable to the pin-1 end of the 50-pin connector (for a narrow SCSI device) or the 68-pin con- nector (for a wide SCSI device) on the adapter card, and then press the cable connector firmly onto the adapter card connector.

CAUTION: You must match the colored strip on the internal SCSI cable with pin 1 on the adapter card connector to avoid possible damage to your system.

•If you are installing an external SCSI device, connect the other end of the external SCSI cable to the external connector on the adapter card.

For additional instructions, see the documentation that came with the adapter card.

8.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, con- nect 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.

9.If you installed an externally accessible device, remove the front bezel and remove the front- panel insert for the drive bay from the front bezel. Then replace the front bezel.

For instructions, see “Removing and Replacing the Front Bezel” and “Removing and Replacing Front- Panel Inserts” found earlier in this chapter.

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

11.If necessary, enter the System Setup program to update the system configuration information.

If you installed a SCSI hard-disk drive, set the Drive category (0 or 1) under Drives: Primary to None. For instructions, see Chapter 2, “Using the System Setup Program.”

Tape drives attached to a SCSI host adapter card are not part of the system configuration information.

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

For instructions, see the next subsection, “Partition- ing and Formatting SCSI Hard-Disk Drives,” and your operating system documentation.

13.Test the SCSI devices.

Test a SCSI hard-disk drive by running the SCSI Device(s) Test Group of the Dell Diagnostics. See your Diagnostics and Troubleshooting Guide for information on running the Dell Diagnostics and troubleshooting any problems that may occur.

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 pro- vided 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.

NOTE: On systems with hard-disk drives larger than

2 GB, create a primary partition of 2 GB and divide the remaining capacity into partitions of 2 GB or less. For example, a system with a 2.5-GB hard-disk drive would have a primary partition of 2 GB (drive C) and a second
