Kit Contents
Kit Contents
Make sure that you have kit A4505A and that it contains the following
items:
• PCI tray assembly
• Boot ROM for Model 743 VMEbus board computer
• IC Removal Tool
• Anti-static Strap (Disposable)
Tools Required
You’ll need the following items to install the PCI Module:
• Medium flat-tipped screwdriver.
• Static-free work area.
Prerequisites
Your system must be running version 10.20 or later of the HP-UX operating
system.
The PCI module upgrade does not support HIL devices. You must remove
any devices connected to the HIL interface connector on the EISA tray.
NOTICE: Before removing your HIL keyboard, use the SAM utility to make sure that
the P/S2 driver is configured in the HP-UX kernel. Refer to the manual
HP-UX System Administration Tasks (B2355-90079) for information on
configuring the HP-UX kernel.

Procedure
If you need keyboard and mouse support, you need a Hewlett-Packard P/S2
compatible keyboard and mouse to connect to the P/S2 connectors on the
VMEbus board computer.
Procedure
1Stop any application programs, then shut down your workstation.
2Turn the workstation off, and unplug the power cord(s).
WARNING: To avoid electrical shock, make sure you unplug the power cable from the wall
outlet and the system unit before proceeding any further.
CAUTION: The internal components of your workstation 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 workstation and upgrade kit components carefully to prevent
damage from mechanical shock.
3Using a flat-tipped screwdriver, unscrew the captive screws inside the
EISA module handles five to seven turns (until each screw pops out).
4Grasp the EISA module handles and pull the EISA module out of the
chassis, as shown in Figure 1.

Procedure

5Note that the slots are numbered on the front of the tray from 1 to 4.
NOTICES: This PCI tray only supports option cards with +5 volt bus signalling.
If your workstation application requires several accessory cards and mass
storage devices, power budgeting may be required. This ensures the power
needed for these internal devices does not exceed the power available in the
system.
The PCI tray provides power for option cards from both a +3.3 Vdc source
and a +5 Vdc source. Cards may use either or both power sources, up to
25W per slot. However, the +3.3 V dc source is limited to 39.8 W
combined for slots 1 and 2, and 39.8 W combined for slots 3 and 4. For
example, if the card in slot 1 draws 25 W at +3.3 V dc, only 14.8 W at +3.3
V dc is available to a card in slot 2. The limits of + 5 Vdc is 25 W per slot.
If you upgrade your system, adding more: RAM cards, mass storage
devices, or VME, or PCI accessory cards, you must recompute the power
budget to ensure the new configuration is within the system’s capability.
Refer to your system’s documentation for other power limits.

Procedure
Cards for slots 1 and 2 are installed component side up; cards for slots 3
and 4 are installed component side down.
Loosen the card retainer captive screw (see Figure 2) for the appropriate
slot, and then remove the card retainer, as shown in Figure 3.

Procedure

to update its firmware to make use of the PCI module. (Model 744 board com-
puters do not require a firmware upgrade.)
A new Boot ROM is shipped with the PCI Module upgrade kit. To deter-
mine if the Boot ROM in your system needs to be replaced, you need to
determine the revision number, which can be done in 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 revi-
sion 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 that Boot ROM with the one in this kit. If
the revision number on the Boot ROOM 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.
aLoosen the board computer’s four captive screws.
bPush the ejector handles to the outside of the board and remove the board
computer from the Model 748 card cage.
cRemove any option cards, if installed. Refer to the Model 743 Owner’s Guide
for specific instructions for you option card.
NOTE: Before removing the Boot ROM, note its orientation. The replacement Boot
ROM must be installed in the same orientation.
dRemove the Boot ROM from its socket using the IC removal tool.
eAlign the new Boot ROM in its socket and carefully press it into the socket.
