Figure 1. Installing a SCSI adapter, overview
F’lgure 1 presents an overview of installing the adapter in an HP 9000 Series Xxx
computer system. The procedure is slightly different for the HF’ 9000 Series T6xx and will
be noted where different. Installing the SCSI adapter consists of the following major steps:
Shut down the operating system using shutdown -h 0 (not reboot) and turn
computer power off.
Install the adapter
Connect cables and peripheral devices, and check for no duplicate ADDX.
Terminate the SCSI bus.
Switch power on to the peripherals, then to the computer.
Configure the software to include the adapter.
Verify operation.
12 hstdlation Procedures
Prepare to Install the Adapter
Refer to your computer manuals for any additional information necessary to install the
adapter in your computer system.
Before installing the adapter, you should perform the following steps:
n
Observe antistatic precautions.
n
Verify product contents.
n
Record adapter identification information.
n
Gather tools and accessories.
Observe Antistatic Precautions
This product contains electronic components that can be damaged by an electrostatic
discharge. To avoid damage, follow these guidelines:
n
Store the adapter in a conductive plastic bag until you are ready to install it.
m
If possible, work in a static-free area.
a Use a grounding wrist strap connected to the metallic chassis of the computer.
Verify Product Contents
n
See “Product Contents” on page 8 and make sure you have all contents.
InstaUationProcedures 13
Record Adapter Information
Record the part number and date code of the adapter for future reference. If your
adapter requires service in the future, the part number and date code will be needed by
HP service personnel. This information is provided on stickers affixed to the adapter.
See the example below (note that your information might differ from the example).

Gather Tools and Accessories
The only tools required when installing the SCSI adapter are a #lO Torx driver or a
small flabblade screwdriver, and a grounding wrist strap.

Installation
Rocedures
Shut Down the Operating System and Switch Off the Computer
1.
Before installing the adapter, shut down the computer operating system
(using shutdown -h 0, not reboot). Refer to your computer system manual
for proper shutdown procedures to avoid corruption or loss of data.
2. Turn computer system power off.
3. Unplug the computer’s power cord.
4. Turn power off on all peripheral devices.
WARNING Unless otherwise noted in your computer system manuals,
failure to properly shut down the system and remove power
may create a personal hazard, or may result in hardware
damage or data corruption.
lnstallstion Procedures 16
Set SCSI Adapter DIP Switches
DIP switches on the SCSI adapter are used to set the SCSI address of the adapter.
These switches are preset at the factory at address 7 and should not need to be changed
unless there are multiple SCSI initiators on the same SCSI bus. This situation would
only occur in a multi-host environment, that is, if you are using the ServiceGuard
product.
If you need to set the DIP switches, the location of the switches on the SCSI adapter is
shown in figure 2. Component locations are the same for the HP A2969A and
HP A3644A SCSI adapters. The only physical difference in the two adapters is in the
type of front faceplate (also called bulkhead). The table on page 18 shows the SCSI
addresses for the various switch settings. For bus arbitration the order of priority with
the highest priority first is: 7,6,5,4,3,2,1,0, 15, 14, 13, 12, 11, 10,9,8.
Note
The SCSI adapter is factory set to SCSI bus address ‘7’ and should not
be changed unless it is used in a multi-initiator system.
If there are two adapters on the same SCSI bus, one should be set to
‘7’ and the other to ‘6’.
Address ‘7’ is the highest priority address on the SCSI bus followed by
‘6’. If the SCSI host adapter doesn’t have the highest priority,
performance wdl degrade or the SCSI bus may hang.
