1I/O Upgrade
This I/O Upgrade manual provides information for expanding the I/O capability of the HP 3000/9x9KS
and HP 9000/K2x0, K3x0, K4x0, and K5x0 computer systems.
Introduction
The Upgrades available are shown in Table 1-1.
Table 1-1 Available Upgrades
HP-HSC I/O upgrades are achieved by the addition of an expansion card with two or four slots.
However, two and four slot Primary I/O expansion cards cannot be installed in the same computer. The
HP9000/K5x0 systems allow the addition of a secondary I/O expansion.

Backplane Card Slot Color Codes
The following color bars appear above the slots on the system backplane:
Table 1-2 Color Codes
I/O and processor cards have matching color codes to assist in correctly matching the cards to the right
slots.
Electrostatic Discharge
Computer systems contain assemblies and components that are sensitive to electrostatic discharge
(ESD). Carefully observe the precautions listed in this section and use the ESD wrist strap, ESD sheet,
and ESD foam pad provided in the ESD kit (part number A3024-80004). The following precautions can
significantly reduce the risk of system failure or component damage due to ESD.
• Always wear a grounded wrist strap when working around a system or handling any assembly, component, or
card.
• Treat all assemblies, components, cards, and connections as sensitive.
• When unpacking cards or components to the system, keep the item in it's conductive bag until it is ready to be
installed.
• Keep body movement to a minimum, this generates static electricity that causes ESD.
• Avoid working in carpeted areas.
• Try to select a work area where potential static sources are minimized.

b. HP9000/K5x0 systems only.

Tools required
Anti-Static Wrist Strap
The anti-static wrist strap is a bracelet like strip that goes around either wrist. The other end of the strap
connects to a convenient metal surface on the computer cabinet.
Anti-Static Mat
The anti-static mat can be either the conductive bag, the ESD sheet, or the ESD foam pad. The anti-static
mat does not have to be connected to the cabinet. It should be placed close to the computer while
performing the upgrade tasks.
Tools required
To accomplish the upgrade procedures to the computer the following tools are required:
• A Torx #10 driver. (This is the preferred tool)
• A flat blade screw driver. (this can be used if a Torx driver is not available)
• A3204-80004 ESD Kit
• Chip extraction tool (HP part number 8710-1982)
• Flashlight or alternate light source (recommended but not required)

HP-PB Upgrade
CAUTION The procedures outlined in the HP-PB UPGRADE section are to be performed by trained
and experienced Field Service personnel. If you have not received Hewlett Packard Service
Training or do not have the equivalent hardware experience, DO NOT attempt these
procedures.
To expand the HP-PB I/O capability of the computer, the Programmable Array Logic (PAL) chip on the
system board has to be changed. The PAL chip is accessed from the back of the computer and is located
in the same place for either the HP 3000 or the HP 9000 systems. Figure 1-1, item 1, shows the PAL
location with all components removed from the back of the computer.
Figure 1-1 PAL Chip Location
HP-PB Upgrade Procedures
Be sure to observe all ESD precautions. The suggested time to perform the upgrade is at a non-peak
usage for the computer. To accomplish the upgrade, perform the following steps:
1. Log Off all users and stop all active applications that may be running.
2. Perform a system backup of the entire Operating System and data base. If this is not feasible, perform a backup
of the data base. (This should be done at a scheduled interval as common practice for protecting any new data or
changes to the existing data base.)
3. Perform a system shutdown. Enter "/etc/shutdown -h" at the prompt.
4. Turn the computer key switch to the STANDBY position.
5. At the rear of the computer, unplug the power cord.
6. Loosen the four (two top and two bottom) captive screws on the power supply, then grasp the extractor levers
and pull them out.

HP-PB Upgrade
NOTE On HP9000/K250/K260/K450/K460/K370/K380/K570/K580 and 979KS systems, the
power supply has six captive screws, three each on the top and bottom.
7. Grasp the handle on the power supply and pull it out of the computer.
CAUTION The power supply may weigh as much as 26.5 lbs (12 kg). Be careful lifting it and be
careful where you put it down.
8. Remove the back CPU cover plate by loosening the two (one top and one bottom) captive mounting screws and
pulling the cover plate away.
9. Carefully remove the CPU cards (if they are present) and place them on the anti-static sheet.
10. Reach into the computer and insert the tapered end of the extraction tool (8710-1982) into one of the extraction
slots (Figure 1-2, item 1) in the PAL socket (U30).
Figure 1-2 PAL Chip Socket
11. Gently pry up on the corner of the PAL chip (each side) until you can safely remove it. Be careful not drop the
chip inside the computer cabinet, because it could fall into the fan compartment.
12. Match the beveled corner (Figure 1-2, item 2) of the PAL socket to the beveled corner of the PAL chip
(A2375-81801).
13. Place the PAL chip into the socket and gently push until it fully seats.
14. Remove the HP-PB1 cover plate, and install the HP-PB card guides (5062-9367) and single high bulkheads
(5062-3343).
15. Replace the power supply and CPU card(s) that were removed.
16. Connect the power cord to the rear of the computer.
17. Turn the computer key switch to the ON position.
18. Observe the Front Panel Display and Console for any error or fault (FLT) messages.
Figure 1-3 shows the added HP-PB I/O slots. The four slots under the HP-PB 1 title are the additional
I/O slots. Any supported HP-PB I/O cards can now be installed into the computer.
