Preface
Intended Audience
This manual is written for Digital customer service engineers and selfmaintenance customers servicing DEC 7000 AXP or VAX 7000 systems.
This manual is a follow-on to Basic Troubleshooting and Advanced
Troubleshooting.

Document Structure
This manual uses a structured documentation design. Topics are organized into small sections for efficient on-line and printed reference. Each
topic begins with an abstract. You can quickly gain a comprehensive overview by reading only the abstracts. Next is an illustration or example,
which also provides quick reference. Last in the structure are descriptive
text and syntax definitions.
This manual has three chapters and one appendix, as follows:
•

Chapter 1, Adding or Replacing CPUs and Memories, describes
how to add or replace these modules.

•

Chapter 2, Servicing the CPU, explains how to restore the system
environment to its state before the changes were made.

•

Chapter 3, Updating Firmware, tells how to make updates to firmware on processor or I/O adapter modules.

•

Appendix A, Kermit Parameters, shows what parameters must be
set for using the Kermit program, which is used in down-line loading
flash ROM code.

Conventions Used in This Document
Terminology. Unless specified otherwise, the use of "system" refers to
either a DEC 7000 AXP or VAX 7000 system. The DEC 7000 AXP systems
use the Alpha AXP architecture. References in text use DEC 7000 to refer
to DEC 7000 AXP systems.
When a discussion applies to only one system, an icon is used to highlight
that system. Otherwise, the discussion applies to both systems. Thus, the
abstract for a module that applies only to DEC 7000 systems would look
like this:
This section shows a sample boot of OpenVMS Alpha AXP
DEC from the RRD42 CD drive for DEC 7000 systems. The first
7000
step is issuing the show device command to determine the
location of the RRD42.
Book titles. In text, if a book is cited without a product name, that book is
part of the hardware documentation. It is listed in Table 1 along with its
order number.
Icons. The icons shown below are used in illustrations for designating part
placement in the system described. A shaded area in the icon shows the
location of the component or part being discussed.

This chapter provides information on how to remove and install processor
and memory modules in DEC 7000 and VAX 7000 systems. Sections include:
•

What Is Required

•

LSB Configuration Rules

•

Identifying the Kernel FRUs

•

Removing a Module from the LSB Card Cage

•

Inserting a Module in the LSB Card Cage

•

Verifying the System

For information on servicing I/O modules, see the Platform Service Manual; it also describes removal and replacement of the LSB centerplane

1-2 Adding or Replacing CPUs and Memories

Processor and memory modules reside in the LSB card cage, a centerplane
card cage with nine slots for modules. The LSB card cage always contains
an IOP module, a clock module, and at least one processor and one memory
module (see Figure 1-1).
To add or replace modules, you will follow the steps in Sections 1.2 through
1.6. Then you will:
•

Set system parameters to the original operating environment
(Chapter 2).

•

Upgrade firmware if required (Chapter 3).

1-4 Adding or Replacing CPUs and Memories

The LSB card cage (see Figure1-2) has nine slots. Slot numbers are
equivalent to node numbers. Four slots are at the front of the cabinet
(nodes 0 through 3, right to left), and five slots are at the rear (nodes 4
through 8, right to left).
A system can have up to six processors and up to seven memory modules,
as space allows. The maximum memory configuration is bounded by the
operating system support and the physical slots.
•

The first CPU module is installed in node 0 (in the front at the far
right).

•

Additional CPU modules are installed in slots 1 through 5.

•

The IOP module is in node 8.

•

The first memory module is in node 7.

•

Additional memory modules are installed next to filled slots. Modules
are installed contiguously to the centerplane of the card cage. Install
additional memories alternating between installation from the front
and the back of the cabinet (see the example below of a 2 processor, 4
memory system).

•

Install filler modules in all empty slots to direct the airflow through
the card cage.

1-8 Adding or Replacing CPUs and Memories

Perform an orderly shutdown of the system.

Turn the keyswitch on the front control panel to the Disable position
and wait for the control panel yellow Fault LED to stop flashing.
When the Fault LED stops flashing, power has been removed from
the LSB backplane and you may safely proceed.

Open the cabinet door by holding the recessed handhold and pulling it
out toward you.

Put on the antistatic wrist strap.
CAUTION: You must wear a wrist strap when you handle any modules.

Release the plate covering the LSB card cage by loosening the two
thumbscrews on the end of the plate. The plate is connected to the
card cage by a cable; push the plate to one side.

On the module you are removing, use your thumbs to pull the two
black restraining clips out and to the right (see Figure 1-5, step 1).
The clips snap when they open.

Pull both levers out at the same time until they are perpendicular to
the front of the module (see Figure 1-5, step 2). This frees the module
from the backplane.

Holding the levers, pull on the module until it is out far enough to hold
it underneath as you remove it.

When the module becomes free of the card cage, hold it with both
hands, and place the module on an ESD pad in a safe area. If the
module is being replaced, pack the module in the box from the new
module.

BXB-0091A-92

1-10 Adding or Replacing CPUs and Memories

Follow Steps 1 through 6 in Section 1.4 and then:
1.

If you are adding a module, remove the filler module from the slot
where you will install the new module. Hold the filler module firmly
on the vertical piece closest to you and gently pull it out toward you.
Place it aside for return.

On the module to be inserted, pull out the two black restraining clips
to the right and pull the two levers out until they are perpendicular to
the front edge of the module. The clips snap open.

Pick up the module to be inserted, holding it securely with both hands.

Align the bottom tracks of the module with the tracks in the card cage
slot (see Figure 1-6). Align the top ridge of the module with the track
at the top of the card cage slot.

Holding the module level, gently guide it into the card cage. If you encounter any resistance, check the alignment of the tracks and reinsert.
As the module slides in, release your hand from the corner and guide
the module with two hands as you insert it.
When the module is fully inserted, the front of the module will be flush
with the card cage. Note that the module does not click when it is
fully inserted.

Holding the two metal tabs, push both of them toward the edges of
the module simultaneously. Check that the ends of the metal tabs are
fitting into the guides of the card cage slot (see Figure 1-6). Push the
levers toward the module case.

Snap the black restraining clips across the levers to secure the module.

Check that filler modules are placed in all unused slots.

Replace the plate covering the card cage by tightening the two thumbscrews.

10. Close the cabinet doors.

1-12 Adding or Replacing CPUs and Memories

Power up the system by turning the keyswitch from Disable to either the
Enable or Restart position. Power sequencing begins and the system runs
self-test. Check the self-test display to make sure that the system recognizes the newly installed modules.
Example 1-1 shows the self-test display of a system in which one processor
and one memory module were added. The newly installed modules are at
nodes 1 and 6, respectively.
1

On the TYP line the P indicates that processors are at nodes 0 and 1.
The M indicates that memory modules are at nodes 6 and 7.

The plus signs on the ST lines indicate that the modules passed their
self-tests.

Two I/O channels are part of the system, both XMI buses. All adapters connected on the first channel’s XMI passed self-test (see C0 XMI
line). One adapter on the second channel’s XMI failed self-test as indicated by the minus sign (see C1 XMI line).

5

These two lines show the memory interleave set and size.
The identification line shows the system firmware revision level and
serial number.
If the primary processor is new to the system, the system serial number will not be shown. You must enter this information, along with
any other system parameters in effect before the processor was
changed. Chapter 2 explains how to set the parameters.

If any processors or memory fail self-test, refer to the appropriate Advanced Troubleshooting manual.

Variable Description

Another important environment variable, not shown in Table 2-1, because
it is not a default variable but may be defined by the customer, is a nickname. Should the customer want to have a default boot path for a cluster
and a different local one, a nickname variable may be used for that purpose. Nicknames are set by a console command of the form create -nv
old_disk dua0.0.0.4.0. The -nv option indicates this nonvolatile environment variable will be stored in EEPROM. Once old_disk is so defined,
one can type boot old_disk at the console prompt. Once the environment
variable old_disk has been defined, it can be modified with the set command.

2.2 How to Replace the Only Processor
When replacing the only processor in a system, you must store the
system ID and customized boot paths. If the customer changed
console environment variables from the default values, you will
want to set them as the customer wishes.

#
# Enter LARS number.
# Enter message.

After you have removed and replaced the defective module, following the
instructions in Chapter 1, take the following steps:
1.

Power up the system. Self-test is run and you need to decide whether
the new CPU module is functioning properly. If it is not, try reseating
the new CPU and/or refer to the Advanced Troubleshooting manual;
otherwise continue.

Retrieve the console printout of environment variables, system serial
number, custom boot paths, and any other system-specific configurations saved in the Site Management Guide.
If this information has not been saved, you can find the system serial
number on the barcode at the back of the system cabinet on the surface just below the AC input box. Details on boot paths and changed
console environment variables you will need to get from the system
manager.

Once you have collected the data you need, enter the console commands shown in Example 2-1 that you need. For example, you may
or may not need to use the show device command, which sizes the
system and can be used to see what devices are available. The fields
after the device name indicate the path to the device and are necessary when specifying the bootdef_dev environment variable.
a. You will definitely need to set the system serial number.
b. You will definitely need to set the bootdef_dev.
c. For example, you may need to set the boot_osflags depending
upon the operating system used and how the system manager normally boots the system.
d. If you have a list of environment variables from the Site Management Guide, you will want to compare it against the output given
by the show * command. If there are differences, you will want to
change the variables using commands similar to those that follow.
e. You may need to set one or more special boot paths depending
upon how the system manager configures the system.

Once the console environment is set up, verify the repair by booting
the system. If there are alternative boot paths, you will want to make
sure that all boot paths function properly.

Use the set eeprom field command to enter the 8-digit LARS number
and a short message (up to 68 characters), stating the date and reason
for service, into the EEPROM.

Boot the system and return control to the customer.

Servicing the CPU 2-7

2.3 How to Replace the Boot Processor
In cases where the boot processor in a multiprocessing system is
the CPU that is in need of repair, you need to manipulate which
CPU receives data from the console terminal.

2-8 Servicing the CPU

There are at least two factors to consider when replacing a primary CPU:
1.

The desire to retain the system environment.

The possibility that the new CPU is at a higher or lower firmware revision than other CPUs in the system. 2 shows the mismatch message should the firmware differ between CPUs. Note that in this case
the newer primary has a higher firmware revision than the secondary.

The procedure described here takes these into consideration.
After you have removed and replaced the defective primary CPU following
the instructions in Chapter 1, take the following steps:
1.

Power up the system. If self-test fails, refer to the appropriate Advanced Troubleshooting manual; otherwise continue.

Note the firmware revision of the new CPU.

Use the set cpu command to connect the console terminal to another
CPU in the system.

Use the update -e command to copy the EEPROM environment variables from the secondary processor to the new primary processor.
(The update -e command copies the system serial number and other
parameters that can be set, as well as any additional information
stored in the EEPROM to the target CPU.)

If there is a firmware revision mismatch, you should update the
FEPROMs on the older CPUs. To do this, run the console on the
newer CPU. Use the set cpu command to get to the newer version
and then use the update -f command. Note that if there are several
CPUs that need updating, you can use a wildcard to target them all,
as in update -f kn7aa*.

Use the set eeprom field command to enter the 8-digit LARS number
and a short message (up to 68 characters), stating the date and reason
for service, into the EEPROM.

Boot the system and return control to the customer.

NOTE: If the customer used the set cpu_primary command to change the
default which allows all CPUs in the system to become the primary, the set cpu command may not work.
To allow all CPUs in the system to become the primary processor, use the
set cpu_primary ff command. Modify the cpu_primary environment
variable to the customer setting after performing the updates.

2-12 Servicing the CPU

Should an EEPROM become corrupted, the error message, EEPROM image failed to verify, is printed. Should this occur, use the build eeprom
command to rebuild the EEPROM. When the EEPROM is rebuilt, all settings will revert to default settings. Follow Section 2.2 to customize environment variables.
The build eeprom command prompts you for several pieces of information. You can find this information in the following locations:
•

The system serial number is on the barcode at the back of the system
cabinet on the surface just below the AC input box.

•

The 10-digit module serial number is the last number on the barcode
found on the module itself. See Figure 1-4.

•

Most of the module unified 2-5-2-4 part number can also be found on
the barcode. The first number is 80, the second for the DEC 7000 is
E2040 and for the VAX 7000 is E2045, the third is a two-letter module
variant, like AA, and the fourth is the hardware revision. A valid 2-52-4 part number is:
80-E2045-AA-0E04
The dashes should be entered when responding to the prompt.

•

The module firmware revision number cannot be determined in the
field. A proper response to the prompt is 0.00.

If the EEPROM image fails to rebuild, send the module back for repair.
Once the image has been rebuilt, use the initialize command to set the
environment variables to the default values. Customize the system, if necessary, using the set and create commands.

2.6 FEPROM Recovery—Hardware Requirements
When FEPROMs are corrupt and you do not have a CPU to use the
update -f command, you may be able to recover the console and diagnostic code through the console terminal line. A serial line receive program in the serial ROM forces a prompt, AXP- or VAX7000/10000-FRRC>, on the console terminal.

2-14 Servicing the CPU

There are three methods for recovering console and diagnostic code. The
first is to use the update -f command; the second is to use the Loadable
Firmware Update (LFU) Utility; and the third is to downline load the console/diagnostic firmware into the damaged system and copy it into the
FEPROMs. The use of the update -f command can only be done in a multiprocessing system and is documented in Sections 2.3 and 2.4. LFU can
be used when the console is completely functioning and is described in
Chapter 3. The third method, the least desirable, is described here.
Other pertinent information follows:
•

The console terminal must be set at 9600 baud for the AXP-/VAX7000/10000-FRRC> prompt to appear.

•

On site or remote access to the system is required.

•

The procedure may take 20 to 30 minutes to complete if there are no
line problems.

What you need is:
•

An independent source system that can logically connect to the damaged system through the console line. The system can be on site or remote. You do not need a DMB32 as shown in Figure 2-1, but you need
some hardware mechanism to connect to the target’s console port.

•

The source system must have access to an RRD42 or an InfoServer.

•

The software program Kermit must reside on the source system.

•

The AXP/VAX 7000 Console CD-ROM, with the console/diagnostic
code on it. The file name for the console/diagnostic code is
AXP7000_10000_CONSOLE_IMAGE.GROM for the DEC 7000 system
and VAX7000_10000_CONSOLE_IMAGE.GROM for the VAX 7000
system.

The serial line receive program in the serial ROM of the CPU is called
FRRC (FEPROM recovery code). Its function is to receive and store data
sent down the console line.

Servicing the CPU 2-15

2.7 FEPROM Recovery—Software Requirements
and Setup
On the source system you need to "bind" the RRD42 or InfoServer
to a virtual disk container, mount it, and set the terminal speed to
that of the target console.

Example 2-5 Setting Up the Source System
$ set term/speed=9600/perm txa3:

# Set DMB32 port to
# 9600 baud.
# Run LADCP.
# This is the volume label
# from the CD.

$ mcr ess$ladcp
LADCP> BIND VAX7000_V01
VAX7000_V01 is bound to DAD104
LADCP> exit
$ mount/ov=id dad104
# Mount the CD-ROM.
$ dir dad104:[sys0.sysexe]
# Get a directory of the
.
# CD.
.
# Desired file name will
VAX7000_10000_CONSOLE_IMAGE.GROM # be AXP7000_10000_...
# or VAX7000_10000_...
.
$ Kermit
# Enter Kermit from DCL.
Kermit-32> set file type binary
Kermit-32> set retry packet 5
# Set max retries/packet.
Kermit-32> set send time 5
# Set send timeout.
Kermit-32> show all
# Shows all Kermit params.
Kermit-32> set xxx
# Set other parameters.

2-16 Servicing the CPU

Example 2-5 illustrates the steps needed to prepare Kermit with
OpenVMS VAX. What you do is:
1.

First make sure that you have the hardware necessary to perform the
task.

Make sure you have the correct CD-ROM for the damaged system.

Set the terminal speed on the source system to 9600. FRRC only
works at 9600 baud.

Run LADCP at the source system to "bind" the CD-ROM volume name
to a virtual disk container pointed to by a logical name created by
LADCP.

Next, set the correct parameters for Kermit. Example 2-5 shows how
to run Kermit from a DCL prompt and gives examples of setting the
parameters. The show all command produces a list of Kermit parameters that should be compared to the parameters shown in Appendix A.

Set all parameters in accordance with Appendix A.

Servicing the CPU 2-17

2.8 FEPROM Recovery—Procedure
After Kermit has been set up and you are ready to downline load
the file, AXP or VAX7000_10000_CONSOLE_IMAGE.GROM, connect
to the target system, prepare it to receive the file and then load it.
The final steps are to copy the file into the FEPROMs and boot the
system. Note that all commands are entered on the source system.

Example 2-6 Using Kermit to Downline Load FEPROM Code
Kermit-32> connect txa5:

# Line = com path e.g., TXA5

[should now get a FRRC> prompt on remote terminal]
VAX-7000/10000-FRRC> r
Ctrl/] C

# Type FRRC receive command.
# Escape sequence to return
# to Kermit.

Kermit-32> send

Kermit-32> connect

# To get a status report.
# To reconnect to FRRC on the

VAX-7000/10000-FRRC> Ctrl/]C # Escape sequence to return
# to Kermit.
Kermit-32> exit
# To return to DCL.
$

2-18 Servicing the CPU

Assuming you have the correct CD-ROM in an InfoServer, you are now
ready to connect to the damaged target system and downline load the
code. Example 2-6 illustrates a VAX 7000 recovery. Follow the same
steps for the DEC 7000, using the AXP7000_10000_console_image.grom
file.
1.

At the Kermit prompt, connect to the target system. Here are two examples of connections:
connect txa5:

Logically connect to the target console line

connect lta1004: Logically connect to the target console line
2.

Once connected to the console, make the target system ready to receive the code by typing r (for receive) at the VAX-7000/10000-FRRC>
prompt on the source system.

Return to Kermit on the source system by typing Ctrl/ ] C.

Downline load the console and diagnostic code by using the Kermit
send command. Here are several examples to help you with the location and name of the file:
send dadx:[sys0.sysexe]vax7000_10000_console_image.grom
send dua0:[directory_name]vax7000_10000_console_image.grom
If the file was copied to a disk earlier.

Once the code has been downline loaded, reconnect to the target.

Issue the following three VAX-7000/10000-FRRC> commands:
c

causes the checksum to be verified for the code just loaded.

clears and then writes the code into the FEPROMs.

resets the system. The console prompt on the target system
should appear and the flash ROM repair should be complete.

Return to Kermit on the source system by typing Ctrl/ ] C.

Exit Kermit.

Chapter 3
Updating Firmware
Use the Loadable Firmware Update (LFU) Utility to update system firmware. LFU runs without any operating system and can update the firmware on any system module. LFU handles modules on the LSB bus (for
example, the CPU) as well as modules on the I/O buses (for example, a CI
controller on the XMI bus). You are not required to specify any hardware
path information, and the update process is highly automated.
Both the LFU program and the firmware microcode images it writes are
supplied on a CD-ROM. You start LFU on DEC 7000 systems by booting
the RRD42. On VAX 7000 systems, you start LFU by booting the
InfoServer on your Ethernet.
A typical update procedure is:
1.

Boot the LFU CD-ROM.

Use the LFU show command to indicate modules whose firmware
needs to be updated.

Use the LFU list command if you want to check the firmware version
numbers on the CD-ROM.

Use the LFU update command to write the new firmware.

Exit.

3-6 Updating Firmware

If you type just the command show without a device mnemonic, LFU
prompts for the device mnemonic. All the commands that require device mnemonics will prompt.
If you enter ? (or help) for the device, a table displays the syntax for
specifying devices. All the commands that require device specifications
use this syntax. Note the use of wildcards. For example,
show kdm70* would display all KDM70 controller modules.
If you enter an exit command at the device prompt, LFU returns to
the function prompt for another command.
The most useful form of the command is show * which displays every
module in the system. Note in this example that the CPU and CIXCD
modules require updating. (In other words, the + means that the firmware version on the CD-ROM is higher than the version on the module.)

Function?

This command specifically requests firmware updates for the CPU and
CIXCD modules. Note the syntax of a device list, separated by
spaces.

LFU requires you to confirm each update, if you named the modules
specifically.

Status message reports update and verification progress.

LFU prompts for each device in turn.

This is a second example. When you specify the * wildcard, LFU tries
to update all devices.
LFU prints the configuration table and prompts before all devices are
updated.
This message appears because, in this example, the firmware on the
DEMNA module is not at a lower revision level than the firmware image on the CD-ROM. You can still request LFU to perform the update.
If the module version is equal to the update firmware, you may have
previously tried the update (making the module and CD-ROM firmware images the same revision). However, if the verification process
had reported an error, you can repeat the update. Also, this feature
allows you to update a module with an older revision of firmware.
This is another example, using a wildcard to request LFU to update all
DEMNA adapters in the system.
When you use a device mnemonic followed by the wildcard, LFU
prompts once for all devices of the same type.

CAUTION: Never abort an update operation; you will corrupt the firmware on the module.

3-14 Updating Firmware

Display shows the system physical configuration. Display is equivalent to issuing the console command show configuration. Because it
shows the LSB slot for each module, display can help you identify unknown devices.
Verify reads the firmware from the module into memory and compares it with the update firmware on the CD-ROM. If a module already verified successfully when you updated it, but later failed selftest, you can use verify to tell whether the firmware has become corrupted.
The address displayed for a failed compare is relative to the beginning
of the update firmware image.
Verify terminates after 10 comparisons fail.

3.8 How to Update Corrupted Firmware
If LFU identifies a device as unknown, the firmware on the module is corrupted. The update command allows you to specify the
correct device type so that new firmware can be written to the
module.

Issue the show command.

The display indicates an unknown device — LFU is unable to recognize device type.

Issue the display command. Then you can identify the unknown device by looking at the physical configuration.
Display shows that the unknown device is in slot 1 of the second XMI
bus. You inspect the module and identify it as a second CIXCD with
hardware revision A01.
Issue the command update unknown0.
LFU prompts you for only the device name (not mnemonic). The mnemonic is the device name plus a unique number which is assigned by
the system. The device name in this example is cixcd.
If the device has several hardware versions supported by different
firmware images, LFU prompts you for the hardware version so that it
will be updated with the correct firmware image.

Status message indicates that the update succeeded.

To make the device known, initialize the system by exiting LFU.

Initialization has made the device known to the system. The previously unknown device is now assigned device mnemonic cixcd0 by the
system. The previous cixcd0 is now cixcd1.

Updating Firmware 3-19

The CIXCD has only one parameter: the hardware revision. You
would need to modify the value only if the EEPROM had become corrupted.

When you modify the KFMSA, LFU first displays all the parameters
for both ports.

You select which port to modify.

LFU prompts for parameters by category.

LFU displays the DEMNA parameters.

This example modifies one parameter, disabling remote booting.
