Safety and Regulatory Statements
See the Owner’s Guide that came with your system for safety informtion.
Emissions Regulations
Federal Communications Commission (FCC)
The Federal Communications Commission of the U.S. government regulates the radio
frequency energy emanated by computing devices through published regulations. These
regulations specify the limits of radio frequency emission to protect radio and television
reception. All HP Apollo nodes and peripherals have been tested and comply with these
limits. The FCC regulations also require that computing devices used in the U.S. display
the agency’s label and that the related documentation include the following statement:
NOTICE: This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant to part 15 of the FCC rules.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his own
expense.
Canadian Department of Communications (CDC)
This digital apparatus does not exceed the Class A limits for radio noise emissions from
digital apparatus as set out in the Radio Interference Requirements of the Canadian
Department of Communications.

Emissions Regulations Compliance
Any third-party I/O device installed in HP system(s) must be in accordance with the
requirements set forth in the preceding Emissions Regulations statements. In the event
that a third-party noncompliant I/O device is installed, the customer assumes all
responsibility and liability arising therefrom.
Electrostatic Discharge (ESD) Precautions
Electrostatic charges can damage the integrated circuits on printed circuit boards. To
prevent such damage from occurring, observe the following precautions during board
unpacking and installation:
•Stand on a static-free mat.
•Wear a static strap to ensure that any accumulated electrostatic char ge is
discharged from your body to ground.
•Connect all equipment together, including the static-free mat, static strap, routing
nodes, and peripheral units.
•Keep uninstalled printed circuit boards in their protective antistatic bags.
•Handle printed circuit boards by their edges, once you have removed them from their
protective antistatic bags.
Installation Notice
Products designated in the applicable Hewlett-Packard price list as customer-installable
can be installed by computer-knowledgeable customers who carefully read and follow the
instructions provided. Customers who elect to have the product installed by our field
personnel are charged the applicable field installation charge, as covered under the
standard terms and conditions. For more information, please contact your local sales

Preparing to Install a New DDS-DC Drive
The following information describes how to prepare the DDS-DC drive for installation.
Tools Required
The following tools are needed to install the DDS-DC drive:
•#2 Phillips screwdriver
•Small needlenose pliers
•T10 torx wrench
Verifying Kit Contents
Verify that the kit contains one of each of the following:
•DDS-DC drive (part number 0950–3002) and bezel.
•Set of 4 screws (M4x6)
•Power adapter cable
•SCSI I/O cable
•Static strap
•HP DDS-DC T ape Drive User ’ s Guide (A1658–90696)
NOTICE: If any contents of your kit are missing, contact your sales
representative.
Operating System Support
The HP DDS-DC drive supports HP-UX 9.01 and later. This drive does not require any
patches.

Introduction
1–7
Setting the SCSI-2 Address
The DDS-DC drive must have a unique SCSI-2 target address. The DDS-DC drive
jumpers are set at the factory to the SCSI-2 default address of 3, as shown in Figure 1–3.
We recommend that you keep the default address, if possible.
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.
CAUTION: SCSI tape drives are susceptible to mechanical and electrostatic
shock. When handling a DDS-DC drive, always wear the static-
grounding wrist strap that comes in the DDS-DC 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:
DStand on a static-free mat.
DWear a static strap to ensure that any accumulated electrostatic
charge discharges from your body to ground.
DConnect all equipment together, including the static-free mat,
static strap, routing nodes, and peripheral units.
DKeep uninstalled DDS-DC drives in their protective antistatic
bags.
If you need to change the DDS-DC drive 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-DC 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.

Introduction
1–8
3. If you need to change the Operation Mode switches, locate the switches on the un-
derside of the DDS-DC tape drive. Switches 1 and 2 are used to configure the data
compression operation mode. Switches 3 through 8 are used to specify drive connec-
tivity and functionality according to host or customer requirements. The default set-
ting is all switches ON.
Address Jumpers
To set the drive’s address, use the SCSI-2 address jumpers, and perform the following
steps:
1. Attach the static-grounding wrist strap by following the instructions on the package.
Attach one end of the strap to the system chassis.
2. Locate the address jumpers on the rear of the DDS-DC drive. Figure 1–3 shows the
rear of the DDS-DC drive with the significant bits identified.
3. Set the drive’s SCSI-2 target address to an address that’s not used by another SCSI-2
device. Using Figure 1–3 as a guide, use needlenose pliers to set the jumpers. When
finished, refer to “Preparing the System,” later in this chapter, for information on
verifying the jumpers have been set correctly and your system sees the drive.
NOTICE: Do not use SCSI-2 address 7 because the system’s SCSI-2
controller uses address 7 by default. We advise that you do not
use
SCSI-2 address 6 because the root disk drive uses it.
