Introduction

The A4979A PMC graphics card is designed to be used with the Model 744

single board computer (SBC) only. You may install up to four PMC graphics

card in one system. HP-UX 10.20 ACE supports up to four graphics dis-

plays. If you have four PMC graphics cards in your system, and the Model

744 has onboard graphics, you must disable the onboard graphics (using the

instructions provided here).

Use the instructions provided here along with Installing the A4504A PMC

Bridge Adapter and A4509A Expansion Adapter (A4504-90601) (included

with the adapters) and the Owner’s Guide for your system

When you power on the system, or during operation through the use of the

System Administration Manager (SAM), you can choose the correct resolu-

tion for your monitor. The maximum resolutions supported by this card are:

• 1280x1024 - 72 HZ - Double-buffered (monitor type 13), or

• 1600x1200 -75 HZ - 8-plane (monitor type 8)

For multiple display systems, please see HP’s Graphics Administration

Guide (B2355-90109).

Kit Contents

Make sure that you have kit A4979A and that it contains the following

items:

• PMC graphics card

• Mounting hardware

• Static strap

Tools Required

You’ll need the following items to install the PMC graphics card:

• Small flat-tipped screwdriver.

• Static-free work area.

Prerequisites

1There is a minimum firmware revision level for the Model 744 board

computers: a firmware upgrade is needed if the Boot ROM revision is pri-

or to revision 4.0. To determine the revision level of the Boot ROM on

your Model 744, type the command IN FV at the Boot Console Handler

(BCH) Main Menu prompt (more details are available in your Model 744

Owner’s Guide).You may obtain a firmware upgrade and instructions

fromyourlocalCountryResponseCenter(inNorthAmericayoumaycall

800-633-3600) or through the WWW at:

http://us-support.external.hp.com .

2Your system must be running Workstation ACE (1998 06) for HP-UX

10.20 or later.

3If you are connecting a monitor that does not have an EVC-style connec-

tor, you will need HP’s A4168A adapter cable.

4If you need to compute power usage for the PMC graphics card, the PMC

graphics cards draw through the bridge adapter:

• +5 Vdc - 2.33 A (typical)

• +12 Vdc - 2.0 mA (typical)

Prerequisites

CAUTION: The internal components of your system are susceptible to

mechanical and electrostatic shock. To prevent such damage from

occurring, observe the following precautions during the installation

procedure.

• Stand on a static-free mat

• Wear a static-grounding wrist strap to ensure that any accumulated

electrostatic charge discharges from your body to ground. Attach the

static-grounding wrist strap by following the instructions on the pack-

age that contains the strap. Be sure to attach one end of the strap to the

system chassis.

• Handle system and upgrade kit components carefully to prevent dam-

age from mechanical shock.

Procedure

NOTE: If you need to update your Model 744 board computer’s firmware or

operating system as instructed in Prerequisites, update now before

completing the procedure.

NOTE: If you are installing four PMC cards onto a Model 744 that has onboard

graphics, you will need to disable the onboard graphics (directions are later

in the procedure). You will also need to redirect the console path before

shutting off the system:

iReboot the system.

ii If Autoboot is turned on, press any key when you see the following mes-

sage:

Processor is starting Autoboot process. To discontinue,

press any key within 10 seconds.

iii Use the following command at the Main Menu prompt to configure the

console path for a PMC graphics card:

pa con pmc

where nis the PMC card site number.

Procedure

1If this PMC card is being installed in a system that is already in use, before

shutting down the operating system, log in as superuser or root and enter

the following command in a terminal window:

rm /dev/crt*

2Stop any application programs, then shut down your system.

3Turn the system off, and unplug the power cord(s) and all other cables to

the SBC.

WARNING: To avoid electrical shock, make sure you unplug the power cable from the wall

outlet and the system unit before proceeding any further.

4Using a flat-tipped screwdriver, unscrew the captive screws that secure

the board computer in the card cage.

5Use the ejector handles to eject the board, and pull the board computer as-

sembly out of the card cage.

6Decide which PMC site you will install the card into, and remove the

PMC bridge and expansion adapter (if present) from the Model 744 SBC.

7On the PMC bridge adapter or expansion board, at the site where you will

be installing the PMC card, remove the two screws that secure the bezel

blank, and remove the blank. See Figure 1 and Figure 2.

NOTE: When installing a PMC card, ensure that the O-ring type gasket near the bezel

remains in place.

8InstallthePMC card onto the adapter by aligning the front of thecardwith

thefrontbezel,andtherearofthecardwiththeconnectorsandkeying pin.

See Figure 1 or Figure 2. There are four screws that secure the PMC card

from the bottom of the adapter (use the screws included with the kit).

Procedure

9If you are using both the PMC bridge and expansion adapters, connect

them together, making sure that the connector and bezels are properly

aligned, as shown in Figure 3. Ensure that the interboard connector seats

properly by applying pressure to the top of the expansion board and to the

bottom of the bridge board at the interboard connector. There are two

screws that secure the front bezel and four screws to secure the backplane

connectors.

NOTE: If the interboard connector is not tightly seated, PMC cards on the expansion

adapter will not operate.

CAUTION: When installing the board computer and PMC adapter(s) into a Model 748

industrial system, to properly seat the assembly in the card cage you must

push down slightly on the assembly for the last 2.5 cm (one inch) of travel in

order to compress the EMI gasket on the card cage.

11 Insert the board computer with the attached PMC adapter(s) into the card

cage slots until the assembly seats properly and the front panels are flush

against the card cage.

where nis the PMC card site number, and tt is the monitor type number.

17 You can use the following command to get a full list of the valid monitor

types:

co mo list

18 If you have onboard graphics and have installed four PMC graphics cards,

you must disable the Model 744 onboard graphics with the command:

co mo disable builtin

NOTE: If you disable the onboard graphics, and later need to use the onboard

graphics as the console device, use the procedure in your system’s Owner’s

Guide for the “Using the Emergency Interactive Console Search” feature.

19 After configuring the monitor, continue the boot process by using the fol-

lowing command at the Main Menu prompt:

boot

20 If you choose to use the online Support Tools Manager (xstm) to verify operation

of more than two PMC graphics cards in your system, you need to change two

parameters within the System Administration Manager (SAM):

aWithin SAM, select Kernel Configuration

bThen select Configurable Parameters

cChange the following two parameters:

semmni = 128

semmns = 256

dWhen exiting SAM, create a New Kernel with the new configuration.

eChoose to move the Kernel into place and allow SAM to shutdown/reboot the

system.
