Installing an Optical or Tape Drive

CAUTION:

Many repairs may only be done by a certified service technician. You

should only perform troubleshooting and simple repairs as authorized in your
product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered
by your warranty. Read and follow the safety instructions that came with the
product.

1 Unpack the drive and prepare it for installation. For instructions, see the

documentation that accompanied the drive.

If you are installing a SCSI tape drive, you must have a SCSI controller
card installed. See "Installing an Expansion Card" on page 73.

NOTE:

It is recommended that you install the SCSI controller card in

expansion card slot 1 for optimal cable-routing. See Figure 6-2 for the location
of expansion card slot 1.

Configure the tape drive according to the documentation that came
with the tape drive, based on the following guidelines:

a

Each device attached to a SCSI host adapter must have a unique
SCSI ID number (narrow SCSI devices use IDs 0 to 7; wide SCSI
devices use IDs from 0 to 15). Set the drive’s SCSI ID to avoid
conflicts with other devices on the SCSI bus. For the default SCSI ID
setting, see the documentation provided with the drive.

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.

b

SCSI logic requires that the two devices at opposite ends of a SCSI
chain be terminated and that all devices in between be unterminated.
Therefore, you enable the tape drive’s termination if it is the last
device in a chain of devices (or sole device) connected to the SCSI
controller.

2 Turn off the system, including any attached peripherals, and disconnect

the system from the electrical outlet.

3 Open the system. See "Opening the System" on page 47.
4 Remove the front drive bezel. See "Removing the Front Drive Bezel" on

page 49.
