system board.
Route the SCSI cable along the top of the cooling shroud.
14. Check all cable connections that may have been loosened during this procedure. Arrange cables so that they will not catch on the system cover or block the
airflow of the fans or cooling vents.
15. Replace the system cover.
16. Close the front bezel.
17. Reconnect the system and peripherals to their power sources, and turn on the power.
18. Perform a tape backup and verification test with the drive as instructed in the tape-drive software documentation that came with the drive.
This subsection describes how to configure and install an external SCSI tape drive.
Installing the Tape Drive
1. Prepare the tape drive for installation.
Ground yourself by touching an unpainted metal surface on the back of the system, unpack the drive and controller card, and compare the jumper and switch
settings with those in the drive documentation. (See "SCSI Configuration Information," for information on setting the drive's SCSI ID number and enabling
termination [if required].) Change any settings necessary for this system's configuration.
2. Unpack the tape drive (and controller card, if applicable), and configure the tape drive for the system according to the documentation that came with the tape
drive.
3. If the tape drive was supplied with a controller card, perform the following steps to install the card:
a. Open the front bezel (see "Removing the Front Bezel" in "Troubleshooting Your System").
b. Remove the system cover.
c. Install the controller card in an expansion slot.
d. Replace the system cover.
e. Close the front bezel.
4. Connect the tape drive's interface/DC power cable to the external SCSI connector on the back of the system, or the connector on the controller card supplied
with the tape drive.
5. Secure the controller card connection by tightening the screws on the connector.
6. Reconnect the system and peripherals to electrical outlets, and turn on the power.
7. Perform a tape backup and verification test with the drive as instructed in the software documentation that came with the drive.
This subsection describes how to install and configure SCSI hard-disk drives in the system's internal hard-disk drive bays, and how to upgrade the system by installing
a Dell host adapter card.
The internal hard-disk drive bays provide space for up to six 1-inch hard-disk drives. These drives connect to a SCSI backplane board. A SCSI cable connects the
SCSI backplane board to the SCSI host adapter connector on the system board or to an optional SCSI host adapter card such as the Dell PERC host adapter card.
Before You Begin
Before attempting to remove or install a drive while the system is running, see the documentation for the Dell PERC host adapter card to ensure that the card is
configured correctly to support hot-pluggable drive removal and insertion.
SCSI hard-disk drives are supplied by Dell in special drive carriers that fit in the hard-disk drive bays.
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
