CAUTION:
Back up your system data before changing or installing hardware.
Follow the steps in this chapter to install the host bus adapter.

System requirements
To install a nd use the HP StorageWorks U320e SCSI Host Bus Adapter you will need:
• A computer with an available x4 PCI Express expansion slot or larger, such as x8 or x16.
• The HP StorageWorks U320e SCSI Host Bus Adapter package.
CAUTION:
The host bus adapter contains components that are sensitive to electrostatic discharge (ESD). The host bus
adapter c an be damaged by electrostatic discharge. Keep parts in electrostatic containers until needed.
Ensure that you are properly grounded when touching static-sensitive components.

WARNING!
When installing the adapter in a server in a rack, to reduce the risk of personal injury or damage to the
equipment, adequately stabilize the rack before extending a component outside the rack. Extend only
one component at a time. A rack may become unstable if more than one component is extended.
The installation procedure involves the following steps:
1. Planning the installation (see page 14)
2.
Preparing the server (see pag e 16)
3. Installing the adapter hardware (see page 17)
4. Connecting the devices (see page 17)
5.
Validating the SCSI bus (see page 19)
Planning the installation
To minimize system downtime, plan the installation before powering off the server:
1. Plan the SCSI busses.
The adapter has two channels. When planning your SCSI busses, keep the following in mind:
• Total bus cable length varies by the type of attached devices. See Table 2 for details on maximum
cable length. See the documentation for your devices to find the cable length inside the device.

• Ifyoucombinewide16-bitandnarrow8-bitdevicesonthesameSCSIbus,connectthewide
devices first (closest to the connector).
• Refer to the documentation for your SCSI devices to determine whether they are Ultra2, Ultra160,
or Ultra320 SCSI.
NOTE:
HP recommends not mixing Single-Ended and LVD devices on the same bus because the host adapter
card will operate with Single-Ended signaling at UltraSCSI speeds, which will signifi cantly decrease the
speedofhigh-performancetapedrives.
2. Plan the SCSI device termination.
14
Installation
The last device in the bus — that farthest from the adapter — must be properly terminated for each
SCSI bus. When planning device termination, keep the following in mind:
• Use an LVD terminator if you a re only using LVD devices.
Although you can use a Single-Ended terminator, all devices will be limited to Ultra SCSI speeds and
cable lengths. Single-Ended devices require a Single-Ended terminator. If you use an LVD terminator
with Single-Ended devices, the system may hang or devices may not be seen on the SCSI bus. Some
termination manufacturers provide automatically sensing terminators.
• LVD Ultra2 and Ultra160 SCSI devices cannot supply their own termination.
• Wide (16-bit) and narrow (8-bit) devices can be c onnected together on the same connector of the
host adapter card, but wide devices must be attached first, followed by narrow devices.
To terminate the SCSI bus, the cable or adapter used to convert from a wide (68-pin) connector to
a narrow (50-pin) connector p rovides partial termination, allowing the upper 8-bits (or byte) of the
wide SCSI bus to be properly terminated. A narrow terminator should be used on the last narrow
device to terminate the rest of the SCSI bus. A SCSI bus without partial termination between the
wide and narrow devices may at first appear to work correctly, but occasional I/O errors occur
without proper termination.
• Termination power: Host adapters supply termination power to the bus at all times and many
SCSI devices are also able to supply termination power. SCSI signal quality, particularly with long
or marginal quality cables, may be improved if the device supplies the termination power. See
your device documentation for information on your device's ability to supply termination power.
3. Review system documentation to select an appropriate slot to install the adapter.
The combined power consumption of the expansion slots must not exceed the limits for your system.
If you have more than one expansion card installed, ensure power consumption is within the limits
outlined for your system.
4. If the selected installation slot is low profile, replace the mounting bracket on the adapter.
a. Remove the two screws on top of the board that secure the bracket to the board, as shown in
Figure 2.

b. Use a small, flat screwdriver to remove the four stand-offs on the external connectors, as

c. Remove the bracket and replace it with the low-profile bracket. Verify that the new bracket
is oriented correctly, as shown in Figure 4.
