Introduction

Electrostatic Discharge (ESD) Precautions. When performing the upgrade procedures in this guide,
you must observe the following antistatic precautions to prevent da mage to memory boards and system
components from electrostatic discharge. An ESD kit (HP P/N A3024-80004) is supplied with your
memory upgrade kit. This ESD kit contains one wrist strap, one conductive sheet, and one anti-static
foam pad.

• Always wear a grounded wrist strap when working on or around the system, and when handling
printed circuit boards.

• Treat all assemblie s, components, and interface connections as static-sensitive.

• Perform all rem ov al and in stal lat i on in a wo rk area wh ere potential static sources are minimized
(preferably an anti-static work station).

• Avoid working in carpete d areas, and keep body movement to a minimum while removing and
installing boards to minimiz e buil dup of static charge.

Required Tools

• One #10 Torx driver (preferred tool)

• One small flat-blade screwdriver (if Torx driver is not available)

Verifying the Current PDC Firmware

If you are planning to install 64MB, 128MB, 256MB, or 512 MB Memory Modules, you may need to
verify your system’s PDC firmware version to see if it supports that type of memory (see “OS
Requirements and Diagnostic Supp ort for 64 MB and 256 MB Modules” on page A-1). If you need to
upgrade your PDC, see the section entitle d "Obtaining the Correct Firmware Patch."

Using On-Line Diagnostics: (If on-line diagnostics are not present on your system, use the Boot
Console Handler procedure to verify the current version.)

1. At the system prompt, enter sysdiag.

2. At the sysdiag prompt, enter sysmap.

3. At the sysmap prompt, enter cpumap.
The output of cpumap will display the current PDC revision (See Table A-1, Appendix A).

Using the Boot Console Handler:

1. Log on as root, and enter reboot -r. This command will shut down the operating system and reboot

the system.

2. If AUTOBOOT is on, you will receive the following message:

Process is starting autoboot process.
To discontinue, press any key within 10 seconds.

3. At this point, press any key within 10 seconds to interrupt the booting proc ess .

4. The Main Menu is displayed. A prompt will appear as

Memory Configuration and SIMM Installation

Memory in HP 3000 and HP 9000 servers can be added in many different megabyte combinations
depending on your model, your use of existi ng memory, your memory upgrade goals, and what
combination of memory modules you inst all .

NOTE

Regardless of the availability of SIMM slots, the total amount of memory you can install
is dependent on your system model and your operating system. Refer to your system
Owner’s Guide.

The configuration guide lines presented in this chapter will suc cessfully optimize most combinations of
memory modules. It is still possible, however, when adding memory to already-configured memory on
two extenders, to meet these guidelines and still generate a warning that your memory is not optimized.
If that happens, remove all memory modules from both extenders and re-inst all them following the
guidelines provide d below.

Before You Begin

Before you begin, you should understand the following definitions:

A SIMM is a single memory Printed Circuit Assembly (PCA) or memory board. SIMMs have memory
on one side of the PCA only. All SIMMs have their size marked on the board near the upper left corner.

A DIMM is a single memory PCA with memory on both sides of the PCA. All DIMMs have their size
marked on the board near the upper left corner, also.

NOTE

The acronym SIMM is used throughout this document to indic ate either SIMM or
DIMM.

A module is a pair of SIMMs or DIMMs. Memory for your system is purchased and installed only in
modules; never install just one SIMM.

A pair of modules is four SIMM cards.

Confi guring Memory for Optimum Perfor mance

For OPTIMUM memory performance, memory must be installed in a particular slot sequence. This
section provides an overvie w and then detailed procedures for both single- and dual -extender systems.

If your memory is not configured for optimum performan ce, the warning, Memory not optimized for
performance, appears when you boot the system. Your memory will still work, but your system’s
performance may be degraded.

On HP3000/979KS and HP9000/K250/K260/K450/K460/Kx70/Kx80 systems, non-optimized memory
has another impact. The fi rmware include s a new use r-conf igurable fla g calle d auto star t. I f the flag is se t
to OFF, the selftest will detect the performanc e degradatio n when you boot and will inhibit autoboot a nd
autosearch. If you’re not sure whet her a warni ng was displayed (i.e., warnings may have scroll ed off
your console), you can re- display any warning messages. From the Information menu in the user
interface, use the warn command to see any warning messages that came up during the boot.

If you get the warn ing, Memory not optimiz ed, use t he me command in the Informati on Menu of t he user
interface (t he Bo o t Console Handler) to check your memory configuration. This command will not
directly tell you whether your memory is installed for optimum performance; it will only tell you
whether the module s are seated c orrectly and re co gnized as part of your system con figuration. However,
you can review the sequence of memory modules in the memory extende rs. The most importa nt memory
optimization rule is that all module pairs of each memory size should be installed in lower-numbered
slots before any modules pairs (see the proc edures and examples on pages 1-13 through 1-20). If the
display of your memory configur ation shows any sing le modules inst al led before module pairs , you will
need to reconfigure your memory using those procedures.

If the warning Memory not optimized does not appear, your m emor y is at optimum configura tion.

Memory Optimization Procedure for Single Memory Extenders — Overview

CAUTION

Module Installation is a 6-step process

1. Remove any currently insta lled memory modules.

2. Combine the removed and new memory modules and organize them into four groups:

• 512 MB modules

• 256 MB modules

• 128MB modules and 64MB modules (combined in the same group)

• 32MB modules

3. Divide each group into pairs of modules (4 SIMMs) and single modules (2 SIMMs), if any.

4. Identify each slot by its slot num ber and letter (0a, 0b, 1a, 1b, and so on) on the extender.

5. Install any pairs of modules as follows:
A. Install from largest to smallest memory size.

To prevent damage to memory boards and system components from electrostatic
discharge, always wear a ground ed wrist strap when working on or around the system,
and when handling printed circuit boards.

B. Install from lowest numbered to highest number slots.

6. When all pairs of modules have been installed, install any remaining old or new modules:

A. Install from largest to smallest memory size.
B. Install from lowest numbered available slots to highest number slots.

NOTE

NOTE

512MB Memory Modules are only supported on Kx70/Kx80 systems.

Kx70/Kx80 systems with four to six CPUs that use the minimum 256MB memory size
REQUIRE that the memory consist of at least four SIMMs (two modules).

Procedure for Single Memory Extenders — Detailed

Step 1. Remove any modules pa irs from the memory extender.
Step 2. Combine the removed and new memory modules and organize them into four groups:

• 512MB modules

• 256MB modules

• 128MB and 64MB modules (combined in the same group)

• 32MB mo dule s

NOTE

Even though 128MB modules and 64MB modules are in the same group, the SIMMs for
each module size cannot be mixed, i.e., do not combine a 64MB SIMM and a 32MB
SIMM as one module.

Step 3. From eac h memory group, create as many pairs of modules (sets of 4 SIMMs) as possible. A

128MB module and a 64MB module can be used as a pair of modules since they are from the
same group. Set aside any remaining modules of each size for installation last. Remember,
each module consists of 2 same-size SIMMs. Any remaini ng single SIMMs are "unusable."

Step 4. Locat e and identify each available slot by its slot number and letter (e.g., 0a, 0b) on the

memory extender. Identify the sequence of available slots from lowest to highest.

Step 5. Install any pairs of module s (sets of 2 modules) first.
A. Install pairs of modules in decreasing size: start with the largest memory size and end with the

smallest. Within a mixed-group of 128MB and 64MB modules, install the 128MB modules first.

B. Install pairs of modules beginning with the lowest available slot number, then the next higher slot

number. In an empty extender, for example, the first pair of modules will go in slots 0a/0b and
1a/1b; the next in 2a/2b and 3a/3b, and so on.

Step 6. Install any remaining modules, starting with the largest memory size first.

5. Install any pairs of modules as follows:
A. Install from largest to smallest memory size.

B. Install memory by alternating pairs of modules between extenders.
C. Inst al l from l owest num bered availabl e slots to highest number sl ots on the e xtender wit h the most

6. Install any remaining modules (2 SIMMs), filling in the lowest-numbered slots on the extender with
the most available slots.

NOTE

In the examples that follow, the extenders are labeled "first extende r" and "second
extender." It is also useful to refer to these as "Extender 0" and "Extender 1",
corresponding to the lower an d upper ext ender slots in the system memory bay.

NOTE

Adding A Memory Extender

If you are adding a new memory extender at the same time you are adding memory, you
will likely need to remove and re-se que nce all the memory modules from your current
memory extender. Review these opti mization procedures for dual memory extend ers to
understand the need for balancing pairs of memory modules across the two extenders.

Installation Procedure (HP 3000/9x9KS and HP 9000/K2x0 /K4x 0/Kx70/Kx80)

Procedure for Dual Memory Extenders — Detailed

Step 1. You must remove any modules from each memory extender.

If you have only one pair of memory modules in your system, and that pair has been
split across the t wo memory extenders, you will get a "Memory not optimized" warning
when you boot your system. Remove the module from one extender and add it to the
module on the other extender (see Step 5 below).

Step 2. Combine the removed and new memory modules and organize them into four groups:

• 512 MB modules

• 256 MB modules

• 128MB and 64MB modules (combined in the same group)

• 32MB modules.

Step 3. From each memory gro up, create as man y pa irs o f modul es (sets of 2 modules, or 4 SIMMs)

as possible. A 128MB and 64MB module can be used as a pair of modules since they ar e from
the same group. Set aside any remaining modules of each size for installation last.

Remember, each module consists of 2 same-siz e SIMMs. Any remai ning single SIMMs are
"unusable."

Step 4. Locat e and identify each available slot by its slot number and letter (e.g., 0a, 0b) on each

memory extender. Identify the sequence of slots from lowest to highest

Step 5. Instal l any pairs of modules first as follows:

A. Install modules in decreas ing siz e: start with the largest memory size and end with the smallest.

Within a mixed-group of 128MB and 64MB modules, install the 128MB modules first.

B. Install pairs of modules beginning with the lowe st available slot number on the extender with the

most slots open.

If both extenders are empty, the fi rst pair of module would go in slots 0a/0b and 1a/1b on the first
extender; the second pai r of modules would go in slots 0a/0b and 1a/1b on the second extender; the
next pair of modules would go in slots 2a/2b and 3a/3b on the first extender, and so on.

Install all pairs of modules before installing modules.

Step 6. Insta ll any remaining modules, beginning with the large st memory size, filling in the lowest

available slot numbers on the exte nde r with the most slots available.

HP 9000/K100 Memory Upgrade Installation

Installation Procedure (HP 9000/K100)

Electrostatic Discharge (ESD) Precautions

When performing the upgrade procedures in this guide, you must observe the following antistatic
precautions to prevent damage to memory boards and system components from electrostatic discharge.
An ESD kit (HP P/N A3024-80004) is supplied with your memory upgrade kit. This ESD kit conta ins
one wrist strap, one conductive sheet, and one anti-static foam pad.

• Always wear a grounded wrist strap when working on or around the system, and when handling
printed circuit boards.

• Treat all assemblie s, components, and interface connections as static-sensitive.

• Perform all rem ov al and in stal lat i on in a wo rk area wh ere potential static sources are minimized
(preferably an anti-static work station).

• Avoid working in carpete d areas, and keep body movement to a minimum while removing and
installing boards to minimiz e buil dup of static charge.

Required Tools

To perform the procedures in this guide, you will need the following tools:

• One #10 Torx driver (preferred tool)

• One small flat-blade screwdriver (if Torx driver is not available)

Memory Configuration and SIMM Installation

NOTE

To prevent damage to memory boards and system components from electrostatic
discharge, always wear a ground ed wrist strap when working on or around the system,
and when handling printed circuit boards.

Configuring Memory

Memory in HP 9000/K100 servers c an be added in many dif ferent mega byte combina tions dependi ng on
your use of existing memory, your memory upgrade goa ls, and the memory size you use. Memory for
your system is purchased and installed only in modules, whic h are pairs of SIMMs of the same s iz e.
SIMM sizes are 16MB, 32MB, 64MB, and 128MB, which can be combined to for m pairs of modules of
32MB, 64MB, 128MB, and 256MB, correspondingly. The SIMMs each have their size marked on the
board near the upper left corner.

See “Configuring Memory for Optimum Performance” on page 1-13 for guidelines on optimizing
memory

Memory SIMM Rules

Memory SIMM rules for HP 9000/K100 servers are similar to thos e for HP 9000/K2x0/K4x0/Kx70
systems, except that only four pairs of SIMMs can be installed.

SIMMs must be installed in pairs of identical size (i.e. two 64MB or two 16MB)

2-6 Chapter 2

HP 9000/K100 Memory Upgrade Installation

Installation Procedure (HP 9000/K100)

SIMM pairs must be installed in the slot sequence (0a+0b, then 1a+1b, and so on).

The largest-sized modules (SIMM pairs) are installed in the lower number slots, followed by
smaller-sized modules.

NOTE

To prevent damage to memory boards and system components from elect rostatic
discharge, always wear a grounded wris t strap when working on or around the system,
and when handling printed circuit boards.

Removing SIMMs

After removing the Memory Bulkhead as previously described, the SIMMs can be removed. You may
find it necessary to remove existing SIMMs before installing the upgrade SIMMs. Remember that the
final configurat ion of all the SIMMs (existing plus upgrade) must conform to the memory configur ation
rules described previo usly. To remove SIMMs, follow these guidelines:

Chapter 2 2-7

HP 9000/K100 Memory Upgrade Installation

Installation Procedure (HP 9000/K100)

Installing SIMMs (HP 9000/K100)

Open the Ejector Lever (Down Positi on)

Orient the SIMMs Correctly

Each SIMM must be ins erted only one way. The white stripe and no tch on the end of the SIMM must be
toward the upper ejector lever. Orienting the SIMM is done in two steps:
First, insert the lower corner into the connector slot at the bottom to align the SIMM

2-8 Chapter 2

HP 9000/K100 Memory Upgrade Installation

Installation Procedure (HP 9000/K100)

Insert the SIMM Card Partway Until the Fingers On the Card Edge Just Touch the Connector

Close the Ejector Lever (Up Position)

Push the SIMM Card Firmly and Evenly Into the Connector

Chapter 2 2-9

HP 9000/K100 Memory Upgrade Installation

Installation Procedure (HP 9000/K100)

NOTE

Do not "rocker" the SIMM into the connector! Apply force evenly.

After All SIMMs Are Installed

After all SIMMs have been inserted, check them to ensure that they are seated evenly and that all
SIMMS are the same height (an incorrectly seated SIMM may stick out above the others). Also verify
that all SIMM pairs are configured corre ctly according to the SIMM rules described previously in this
guide. You will probably need to use a small flashlight to visually check the SIMMs.

Reattach the Memory Bulkhead

The memory cover plate has to be replaced before normal system operation resumes. The cover plate is
required for system cooling and RFI/EMI nois e suppressi on. Once the cover pla te is in pla ce, proceed to
the power on and verification pr ocedur es in Chapter 3.

1. Reattach the system power cables.

2. Turn on all peripherals fi rs t, the n turn on the system. The system memory is automatically
configured to the system by software.

3. If error messages appear, refer to the following "If There Is a Problem at Power On" section. If the
system boots completely with no error messages, proceed to the "Installation Veri fication" procedure.

If There Is a Problem at Power On

Incorrec t me mory extender instal l ation may result in the following types of problems at power on:

• The boot process could be stopped.

• Log warning and display hex codes.

• Console warning messages.

If any of these proble ms appear, the probable cause is that the memory exte nders are incorrectly seated.
To correct the problem:

1. Turn off power to the system.

2. Halt the boot process by pressing an y key withi n the 10 second period provided by the system
software.

3. Type "ma" at the boot interface console prompt to get to the Main menu.

4. Repeat the power on procedure above.
