Chapter 2
Tape Drive Installation
Introduction
This chapter describes how to install a tape drive in the Compaq 3U RM
Storage Enclosure. Topics covered in this chapter include the following:
■SCSI IDs
■Removing and installing a tape drive
■Cable configurations
■Installing SCSI connectors
SCSI IDs
The default SCSI ID for each tape drive depends on the cable configuration
used in the storage enclosure. If there is one tape drive per SCSI cable, the
default is 0. For two tape drives per SCSI cable, the default for the top tape
drive is 1 and the default for the bottom tape drive is 0.
Before setting the SCSI ID, be sure the SCSI ID complies with the following:
■Each SCSI device on the same SCSI bus must have a unique SCSI ID.
■If the tape drives’ SCSI IDs need to be reassigned, do not duplicate
SCSI IDs.
■Do not use SCSI ID 7 because it is reserved for the controller.

To set or change the SCSI ID of a tape drive, refer to your tape drive manual
for setting the SCSI ID.
Installing a Tape Drive
IMPORTANT: If you are returning a failed tape drive, DO NOT return the slide-out drive
tray.
Perform the following steps to remove and install a tape drive:
1. Power down the storage enclosure.
2. Open the top access door of the enclosure.
3. Remove the shipping screw from the slide tray next to the thumbscrew.
4. Loosen the thumbscrew.
5. Remove the slide-out drive tray by pushing the tray toward the rear of
the storage enclosure 1. Then, grab the front of the tray and pull the tray
out at an angle 2.

7. To position and align the tape drive in the slide-out drive tray, use the
following table to determine which holes to use to align the tape drive.
For more details, refer to the hood label.

8. Once the tape drive is aligned, secure the tape drive with retaining
screws.
9. Repeat Steps 5-7 for all tape drives to be installed.
10. Place the slide-out drive tray in the enclosure at an angle and lay it flat.
Then, slide it toward the front of the enclosure.
NOTE: Ensure that the cut outs on the drive cage line up with the tabs on the enclosure.

Figure 2-2. Installing the slide-out drive tray
11. Secure the tape drive assembly by tightening the thumbscrew.
NOTE: It is not necessary to replace the shipping screw.
12. After the slide-out drive tray is installed, connect the SCSI connector
and the power supply to the tape drives.

Cable Configurations
Depending on the drive installed in the Compaq 3U RM Storage Enclosure,
the cable configuration will vary. If you have more than two tape drives in
your storage enclosure, you will need an additional cable kit and two SCSI
ports.
The table below describes different tape drives with their supported cable
configurations.
Table 2-1
SCSI Cable Configurations
Tape Drive SCSI Cable Configuration
AIT Up to 2 drives per SCSI cable
DAT Up to 2 drives per SCSI cable
DLT 1 drive per SCSI cable
SDLT 1 drive per SCSI cable
DAT Autoloader 1 autoloader per SCSI cable
Installing SCSI Connectors
The 3U RM Storage Enclosure ships with two internal LVD wide SCSI cables
attached to the SCSI connector panel. Up to two additional SCSI cables can be
installed in the storage enclosure.
To install additional SCSI connectors:
1. Loosen the three thumbscrews on the rear panel 1.
2. Slide the top panel toward the rear 2and pull the top panel off 3.

CAUTION: The screw locks may be damaged if they are overtightened with a
nut driver. The screw threads have been treated with a thread-locking
compound, so only moderate tightening is necessary.
