Installing Drives: Dell OptiPlex GX1 Low-Profile Managed PC Systems

file:///C|/infodev/2013/eDoc/OpGX1/SQRG/drives.htm[2/21/2013 11:53:04 AM]

NOTICE: Do not connect devices to all three connectors (internal narrow connector, internal wide
connector, and external connector) on a single SCSI host adapter card. Such a configuration is a
violation of the SCSI specification. You can safely connect devices to any two of these three
connectors on a single SCSI host adapter card.

If you are installing only internal SCSI devices, verify that termination is enabled on the SCSI host adapter
and disabled for all other internal SCSI devices. If you are installing both internal and external SCSI devices,
verify that termination is enabled on the external SCSI device and disabled for the SCSI host adapter and all
internal SCSI devices.

General Procedure for Installing SCSI Devices

CAUTION: To avoid the possibility of electric shock, turn off the computer and any peripherals,
disconnect them from their electrical outlets, and then wait at least 5 seconds before you
remove the computer cover. Also, before you install an expansion card, see "

Safety First —

For You and Your Computer

."

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.

See "

SCSI Configuration Guidelines

."

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.

2. Unpack each SCSI device and prepare it for installation.

Configure the device for a SCSI ID number and, if necessary, enable or disable termination. For
instructions, see the documentation that came with the SCSI device and "

SCSI Configuration

Guidelines

."

3. Remove the computer cover as instructed in "

Removing the Computer Cover

."

4. If you are installing a SCSI host adapter card, configure the adapter card.

For instructions on configuring the card, see the documentation that came with the adapter card and
"

SCSI Configuration Guidelines

."

5. Install the SCSI devices as appropriate.
