1. Check That You Have the Necessary Equipment
Verify that you have kit A4268A FWD SCSI adapter). Ensure that the kit contains the
following parts.
•HP A4268A FWD SCSI adapter card
•Screws (2)
•Boot ROM, upgrade (for use with Model 743 only)

•#1 Pozidriv screwdriver

Preparing for the Installation
1–4
2. System Prerequisites
Your system must meet some hardware and software prerequisites to support the FWD
SCSI adapter. These prerequisites are described in the following sections.
Hardware Prerequisites
The required hardware is as follows:
•GSC Expansion Adapter (A4262A or A4219A) or HCRX/VME Graphics Board
(A4315A or A4316A)
•A minimum of 32-MB RAM if running HP-UX version 10.20, or
a minimum of 16-MB RAM if running HP-UX version 9.x, or
a minimum of 24–MB RAM if running HP–RT
Firmware Prerequisites
The required firmware is as follows:
•A Model 743 Single Board Computer (SBC) may require a firmware upgrade if the
Boot ROM included in this kit is a later version than the one in use on your SBC.
To determine if the Boot ROM of your SBC needs to be replaced, you need to
determine
the revision number , which can be done in one of two ways: use the Boot
Console Handler (BCH) interface as described in the Model 743 Owner ’ s Guide , or
you can examine the label on the Boot ROM – a revision number is printed on the
label. If the revision number on the Boot ROM installed on the Model 743 is a lower
number than the one included in this kit, you should replace the Boot ROM with the
one included in this kit. If the revision number on the Boot ROM installed on the
Model
743 is equal to or greater than the one included in this kit, DO NOT replace
the Boot ROM on the Model 743.
•A Model 744 Single Board Computer does not require a firmware upgrade
Software Prerequisites
The required software is as follows:
•For Model 743 SBC with HP-UX, software release 9.05 or later version.
•For Model 744 SBC with HP-UX, software release 10.20 or later version.
To identify which revision of HP-UX your workstation is running, enter
the following command:

Preparing for the Installation
1–5
uname –r Enter
A line similar to the following is displayed:
A.09.05
If a number less than 09.05 is displayed it means that you need to update
your software before installing your HCRX/VME graphics upgrade.
•For Model 743 and 744 SBCs with HP-R T , the operating system software revision
of the host system must be HP-UX 10.10 or later , and the HP-R T tar get system must
have at least HP-R T 3.01. For more information, refer to the HP–RT 3.01 Release
Notes.
Contact your designated service representative for information on receiving an upgrade to
the correct version of the operating system.
3. Record Adapter Information
Record the serial number of the adapter for future reference. If your adapter needs
service in the future, the serial number will be needed by HP service personnel. This
information is provided on the bar code sticker affixed to the adapter. See the following
example.

Installing the FWD SCSI Adapter
This chapter describes how to install the FWD SCSI adapter. Before beginning the
hardware installation, you must complete the tasks in Chapter 1. The tasks for installing
the FWD SCSI adapter are as follows:
•Remove the single board computer (SBC).
•For a Model 743 SBC, install new Boot ROM, if required.
•Remove a blank cover.
•Install FWD SCSI card.
•Replace the single board computer.
•Connect the disk drive(s).
CAUTION: The FWD SCSI adapter is susceptible to electrostatic shock. When
handling your graphics option board, always wear the
static–grounding wrist strap that came in the kit. Always handle
printed circuit boards carefully.

Installing the FWD SCSI Adapter

1. Remove SBC from the Card Cage.
a. Power down your card cage.
b. Disconnect the power cord(s) from the wall outlet and the card cage.
c. Power off any external peripherals attached to your computer, and unplug their
power cables from the wall outlet.
d. Attach the anti–static grounding wrist strap to your wrist and an exposed piece of
metal on your computer, as described on the wrist strap’s packaging.
