HP Surestore Tape Library 20/700 and
10/180 A5599A DLT Tape Drive
Installation Instruction
(for HP field service use only)
NOTE: If you are intermixing DLT7000 and DLT8000 tape drives in your
library, ensure that your backup application is configured
appropriately. The DLT7000 drive is not forward read-capable and
may overwrite a tape written by a DLT8000 drive.
CAUTION: HP tape library drives are not customer installable or replaceable.
Any servicing, adjustment, maintenance or repair must be performed only by
authorized HP service-trained personnel.
Note to Customer Engineer: This installation may add new technology to
the library that older user’s guides do not address. Please remind the
customer that the latest user documentation is available from the HP
Customer Care website: http://www.hp.com/go/support.

■Installation Notes
• Confirm with the customer System Administrator that the tape library can be powered
off.
• Observe proper power off and power on procedures, as described in the Installation
or Service Manuals.
• HP has the drive factory set the drive to differential operation.
• When you install a DLT8000 tape drive remove the Product ID Label, located on the
drive, and place it in the appropriate box on the Drive Location Label. The Drive
Location Label is located on the inside of the library door, just below the UL label.

■Library Drive Attachment
Tape drives are shipped individually. Due to the size differences of the DLT and 9840
drives, there are a variety of ways of installing the drives. Typically, drive installation moves
from the bottom slot and up.
Refer to Figure 1 and the explanation below for the configuration rules for installing drives.
1. The first callout in Figure 1 shows that the uppermost drive slot in the drive column can only be a
DLT drive.
2. The second callout depicts the size ratio of the 9840 drives to the DLT drives. In size, two
9840 drives fit in the same space as three DLT drives.
3. The third callout shows this ratio again: three DLT drives fit in the same space as two 9840
drives.
4. The fourth callout depicts a mixture of 9840 and DLT drives.
You may also install six 9840 drives plus one DLT drive in a column, where the DLT
drive occupies the top drive slot.
The following table lists the available combinations for one drive column.

NOTE:This graphic depicts the size relationship between DLT and 9840 drives ONLY.
Installation instructions call for installing the 9840 drives in the bottom slots, and the
DLT drives in the upper slots.

■Installing DLT Drives
For DLT drives, follow the procedure below to unpack and install the drives.
DLT tape drives are shipped with the following, non-selectable configurations:
•DLT8000 (manufacturer’s model number)
•Differential operation
Refer to Figure 2 and make sure that the labels on the drive match the drive type and
operation required.
NOTE:Check with the customer for their maintenance agreement on tape drives. If
the customer agreement is to return the drives for repair, have them retain
one shipping box, with packing material, to be sent back to the factory.

NOTE:Refer to Figure 3 for the following procedure.
CAUTION: DLT equipment damage: Do not move the load latch of a tape drive by
hand until told to do so in later instructions.
1. Open the drive access section of the library (at the right side, as viewed from the front of
the library) by lifting up on the two latches. Turn the latches counterclockwise and open
the side door.
2. Open the drive package.
3. Remove the packing material.
4. Refer to Figure 3 while checking the side of the DLT drive for the terminating power
jumper selection.
CAUTION: Loss of data or degradation of performance: HP recommends
supplying terminating power (TERMPWR) from devices attached at both ends of
the SCSI bus. Industry standards advise that no more than three devices provide
terminating power to the bus.
Verify whether TERMPWR for DLT drives is on or off (enabled or disabled) for each
tape drive. If needed, move the jumper to match your requirement.
•TERMPWR On: Install the jumper on the pins shown in the following figure.
•TERMPWR Off: Remove the jumper on the pins shown in the following figure.
You can store the strap by placing it on one pin only.
NOTE:You may need to remove the DLT drive from its library tray to gain
access to this jumper. If removal is required, carefully turn the drive
upside down and remove drive mounting screws. Change the jumper
as required. Replace the drive mounting screws.
5. Carefully place each drive near the rear slots at the right side of the library.

6. Look inside the drive column area and determine the slot you wish to use for each drive.
Following the lifting procedures described in Chapter 2 “Safety and ESD”, of the Instal-
lation Manual firmly grasp the drive at the rear with one hand and place the other hand
under the drive mounting plate.
7. Carefully guide the drive into its slot. Push it in as far as it will go and firmly seat the
drive.
NOTE:In the following step, do not over tighten the thumbscrew.
8. Refer to Figure 4 and turn the thumbscrew clockwise until it is secure.

■Installing DLT Cable Connectors
The following procedures describe how to install the tape channel connectors for the tape
drives.
Standard Drive Column 0 Connectors.
NOTE:Drive column 0 is the standard drive column included in all libraries. It is
the column that contains the calibration label at the bottom. Also, some
of the following steps may require two people.
1. Go to the rear of the library, open the door, and locate the connector bulkhead.
2. Remove the SCSI “Y”channel cable and mounting screws from the drive box.
3. Refer to Figure 5 and insert the two channel connectors into the slots on the interior library
bulkhead, next to the desired drive location.
4. From the rear bulkhead, thread the four mounting screws into the connectors.
5. Tighten the mounting screws with a 3/16-inch nutdriver.
6. Insert the single connector end into the DLT drive.
7. Repeat these steps for all drives in column 0.
8. When you are finished installing all drives, place the drive power switch(es) to the ON (|)
position.
9. Close the rear door.
