Introduction Setting the SCSI-2 Address The DDS-2 drive must have a unique SCSI-2 target address. The DDS-2 drive's jumpers are set at the factory to the SCSI-2 default address of 3 as shown in Figure 1-3. You must also ensure that the Operation Mode jumpers are set for correct drive operation, as shown in Figure 1-4. We ship the drive with the Operation Mode jumpers set to operate correctly with your system. We recommend that you keep the default address, if possible. CAUTION: SCSI tape drives are susceptible to mechanical and electrostatic shock. When handling a DDS-2 drive, always wear the staticgrounding wrist strap that comes in the DDS-2 drive kit, and always handle the drive carefully. Electrostatic charges can damage drives. To prevent such damage from occurring, observe the following precautions during unpacking and installation: D Stand on a static-free mat. D Wear a static strap to ensure that any accumulated electrostatic charge discharges from your body to ground. D Connect all equipment together, including the static-free mat, static strap, routing nodes, and peripheral units. D Keep uninstalled DDS-2 drives in their protective antistatic bags. If you need to change the DDS-2 drive's address or operation mode, follow these instructions, referring to Figures 1-3 and 1-4. 1. Locate the jumpers at the back of the DDS-2 drive. 2. To change the jumper settings, use needlenose pliers to set the drive's SCSI ID to an address that is not used by another SCSI device. Check that the other jumpers are set correctly. 1-7

Setting the SCSI-2 Address
The DDS-2 drive must have a unique SCSI-2 target address. The DDS-2 drive’
s jumpers
are set at the factory to the SCSI-2 default address of 3 as shown in Figure 1–3. You must
also ensure that the Operation Mode jumpers are set for correct drive operation, as shown
in Figure 1–4. We ship the drive with the Operation Mode jumpers set to operate
correctly with your system. We recommend that you keep the default address, if possible.
CAUTION:
SCSI tape drives are susceptible to mechanical and electrostatic
shock. When handling a DDS-2 drive, always wear the static-
grounding wrist strap that comes in the DDS-2 drive kit, and al-
ways handle the drive carefully.
Electrostatic charges can damage drives. To prevent such damage
from occurring, observe the following precautions during unpack-
ing and installation:
D
Stand on a static-free mat.
D
Wear a static strap to ensure that any accumulated electrostatic
charge discharges from your body to ground.
D
Connect all equipment together, including the static-free mat,
static strap, routing nodes, and peripheral units.
D
Keep uninstalled DDS-2 drives in their protective antistatic
bags.
If you need to change the DDS-2 drive’s address or operation mode, follow these
instructions, referring to Figures 1–3 and 1–4.
1.
Locate the jumpers at the back of the DDS-2 drive.
2.
To change the jumper settings, use needlenose pliers to set the drive’s SCSI ID to an
address that is not used by another SCSI device. Check that the other jumpers are set
correctly.
