1. Overview
This guide describes how to install CPU/cache and associated memory module upgrades to PA-7100 Continuum
Series 600/1200 systems at customer sites. The process consists of three parts:
·Use the CPU/Memory Burn ID-PROM tools on VOS or FTX to update ID PROM.
·Add/remove CPU and memory modules on the CPU-Memory board.
·Switch the operational status of the CPU-Memory boards to update the partner.
The procedures in this guide apply only to PA-7100 Continuum Series 600/1200 systems.
NOTE: A special section (Section 7) has been added that describes how to upgrade the
memory in a system by replacing the existing CPU-Memory boards with G75X boards
containing 512-MB memory modules).
2. Operating System and Promcode
Requirements
The following are the minimum VOS and FTX operating system releases and promcode revision levels
required for upgrading the CPU-Memory board.
·VOS 13.1 (13.2.1 for 512-MB memory module)
·FTX 3.0.1 (3.2.1 for 512-MB memory module)
·CPU-memory board promcode revision 31
CAUTION: Make sure the system has been updated to the required operating system version
and promcode revision before performing any part of the upgrade procedure. Failure to do this
may result in a system crash.
3. Hardware Components
3.1 CPU-Memory board
The CPU-Memory board houses the CPU and memory modules, as well as the supporting circuitry and
the board power supply. The board comes in one assembly that accommodates sets of either 72 MHz or
96 MHz CPU modules, and from one to four 128-MB or 512-MB memory modules.
The part number of the finished (top level) assembly is determined by the CPU and memory
configurations. The ID PROM for the top level assembly resides on the CPU-Memory board, and
contains information on the part number, the revision level, and the serial number. This information is set
according to the CPU/memory configuration, and a combination of the CPU-Memory board, CPU
module, and memory module revision levels. The CPU-Memory board serial number never changes,
regardless of part number or revision changes.
Table 1 lists the model numbers of the CPU-Memory boards used in Continuum Series 600/1200
systems.

3.2 CPU Modules
The CPU modules are daughter cards that plug into the CPU-Memory board. They contain the HP
PA7100 chipset, including the CPU, cache, and supporting circuitry.
HP7100 has two different versions, based on the processor's clock speed: 72 MHz and 96 MHz modules.
The CPU modules reside in pairs on the CPU-Memory board. The board has either one pair
(uniprocessor) or two pairs (twin processor) of CPU modules. Figure 3 shows the locations of the CPU
module pairs on the board.
The CPU module is packaged in static protective material. Its serial number, part number, revision level,
and artwork revision are marked on the bottom of the module.
The CPU module pairs must be installed as described in Table 2 and in the locations shown in Figure 3.
Each CPU module is seated on four spacers on the motherboard and is secured with four screws.
CAUTION: Do not mix 72 MHz and 96 MHz CPU modules on the same board. Although no
electrical or physical damage will occur, the board will not pass the self test, resulting in a
red-lit LED.
3.3 Memory Modules
The memory module is a daughter card that contains 128 MB or 512 MB of memory. The CPU-Memory
board assembly supports one to four memory modules, which equals a memory range of 128 MB to 512
MB (using 128-MB modules) or 512 MB to 2 GB (using 512-MB modules).
The memory module is packaged in static protective material. Its serial number, part number, revision
level, and artwork revision are marked on the bottom of the module.
Memory modules must be installed as described in Table 2 and in the locations shown in Figure 3.
Memory module #2 is located above memory module #1 as shown in Figure 3. Similarly, module #4 is
located above module #3.
3.4 Upgrade Kits
Table 1 lists the marketing IDs of the CPU and memory upgrade kits and describes the upgrades.

CPU Model 1225 to 1245 upgrade (96 MHz Twin to 96 MHz Quad CPU)
4. ESD Requirements
Since many of the components on the CPU-Memory board are particularly susceptible to ESD
(Electro-Static Discharge), the CPU-Memory board must be protected from ESD from the time that the
board cover is removed until the cover is securely back in place. ESD protection kits must be employed
when doing reconfigurations of Continuum CPU-Memory boards.
The CPU and memory modules must also be protected from ESD before they are removed from their
ESD protected packaging, and while being handled.
To prevent equipment damage while handling components, you must take the following ESD
precautions:
·A securely fastened ESD wrist strap MUST be worn at all times when removing the components.
·Avoid touching a component's leads or contacts.
Set up the ESD protection kit as close to the system as possible. Instructions for setting up the
rubberized mat, grounding wrist strap, etc. are supplied with the kit.

5. Upgrade Procedure
This section describes the steps needed to install a CPU/Memory upgrade into a customer's system in the
field for both FTX and VOS systems.
CAUTION: ESD protection must be maintained for all parts of this process where the ESD
covers have been removed from the CPU-Memory board.
Before you begin the procedure, check the CPU and/or memory modules you will be adding to the
system. Write down the following information for each component:
·Subassembly model number
·Sub model number
·Serial number
·Revision number
·Artwork revision number
CAUTION: If a board fails during the upgrade procedure, don't attempt to repair it. If the first
board you are upgrading fails, order two replacement boards (both of which are the upgraded
model numbers). If the second board you are upgrading fails during the procedure, order one
replacement board (upgraded model number).
