Specifications and Preparation
This chapter describes the preliminary steps to be performed in upgrading
a VAX 6000 XMI-1 platform to an XMI-2 platform. This upgrade converts
an older Model 200, 300, or 400 system to a Model 500.

1.3 Save EEPROM Contents to TK Tape
Begin preparation for the upgrade by saving the EEPROM
contents to a TK tape. With a blank cartridge in the tape
drive, use the SAVE EEPROM command to copy the contents
of the boot processor’s EEPROM to tape.
Example 1–1: SAVE EEPROM Command

!
!
!

A blank TK tape is in the tape drive. With the upper 1
key switch at Enable and the lower key switch at Halt,
press the Restart button.

Before doing an upgrade you should save the contents of the boot processor’s
EEPROM by copying the image to a TK cartridge. Earlier VAX 6000
systems have TK50 tape drives; later models have TK70 tape drives. The
operation of the TK50 differs slightly from the TK70. See Appendix A of
the Owner’s Manual for your system for more information on the TK tape
drive.

1–6 VAX 6000 XMI Conversion Manual

Example 1–1 shows the steps to save the EEPROM contents:
1

Put a blank TK cartridge in the tape drive. Put the control panel’s
upper key switch in the Enable position and the lower key switch in
the Halt position, and then press the Restart button to generate self-test
results. See the Owner’s Manual for your system for a full explanation
of self-test results.

These numbers appear for Model 400 systems and indicate the progress
of self-test. The progress trace line is displayed by the processor in slot
1.

Note the values here for the EEPROM. The second number indicates if
any patches have been installed. Whenever you do an upgrade, make
sure that the boot processor has the latest patches installed on its
EEPROM before you perform the save operation.

Following self-test, the console prompt appears. At the prompt, enter
SAVE EEPROM. This operation saves the information from the boot
processor and overwrites any existing information on the TK cartridge.

The console program queries you, requiring your confirmation to
proceed with the SAVE EEPROM operation. Enter Y. The save process
takes less than a minute to complete.

The console program confirms that the save operation has completed
successfully. When the console prompt returns, the save operation is
complete. Saved information includes:
System serial number
Systemwide console parameters (baud rate, interleave, terminal
characteristics)
Saved boot specifications
Diagnostic patches

Rewind the tape and remove the cartridge from the drive. Label and
write-protect the tape.

NOTE: This tape should be used only on this system. Each system
has its own identifying information stored in the processor EEPROMs.
Furthermore, tapes written by a TK50 tape drive are formatted differently
from those written by a TK70 tape drive. The TK70 can read data from a
tape written by a TK50, but it cannot overwrite a tape originally written by
a TK50. A TK50, however, cannot read data from a tape written by a TK70.

LEDs and one reset switch.
The green +14V bias LED in the lower lefthand corner is lit when the bias
supply on the fan/power module is working.
WARNING: When the +14V bias LED is off, do not assume the +300V bulk
supply is deenergized. This LED does not indicate the presence or absence
of the +300V bulk supply.
The green LED (L1) in the upper righthand corner of the H7206-B indicates
that the +14V bias on the logic module is working and that the unit has
passed self-test. The eight red LEDs provide fault indications for the power
regulators and for certain other faults such as overtemperature.
Section 3.6 shows passing LED patterns. See Appendix B for a description
of each of the diagnostic LEDs and for troubleshooting instructions.

Figure 3–8 shows passing patterns for the H7206-B LEDs. To power up
the system and generate the LED results, turn the key switch from Off to
Standby:
1. Listen for the click from the H405 power controller. This ensures that
the control panel is connected to the H7206-B and that the H7206-B
is connected to the H405. The STANDBY CMD L signal is sent from
the control panel, through the H7206-B and down to the H405 where
it causes an AC contactor to close, providing AC input power to the
H7206-B.
2. Look for the green bias LED (L1) lit on the H7206-B (see Figure 3–8).
This indicates that the internal bias power supply in the H7206-B
is active (delivering +14V). You should also notice the system fans
(including the small fan in the H7206) spin up. If they start and then
shut down about 30 seconds later, check the 24V power and airflow
sense cable. A 30 second delayed shutdown will only occur on detection
of insufficient airflow.
3. The red L5 (VAXBI H7215) and L6 (VAXBI H7214) LEDs are lit.
NOTE: With the H7242 inhibit cable installed and with XMI-1 modules
installed in the XMI-2 card cage, the red L8 (XMI-1 module in XMI-2)
LED is lit. L8 is not lit when the inhibit cable is not installed and no
XMI-1 modules are in the XMI-2 card cage.
Turn the key switch from Standby to Enable/Secure:
1. The XMI side remains as is.
2. The VAXBI side now comes up. LED L5 (VAXBI H7215) and LED L6
(VAXBI H7214) on the H7206-B now go out.
NOTE: With the H7242 inhibit cable installed and with XMI-1 modules
installed in the XMI-2 card cage, the red L8 (XMI-1 module in XMI-2)
LED remains lit. L8 is not lit when the inhibit cable is not installed
and no XMI-1 modules are in the XMI-2 card cage.
If the system does not power up or if you see any other combination of LEDs
lit, refer to Appendix B.

1. Power up the system by turning the lower key switch to Halt and the
upper key switch to Enable.
2. Check the self-test display for the two processors, each indicated by a
P on the TYP line in the example. If the processors show a plus sign
(+) on both lines STF and ETF, they passed self-test.
3. Check the self-test display for the new memory modules, indicated by
an M on the TYP line, as shown in the example. All four memories
passed self-test, as indicated by plus signs (+) on the STF line.
In Example 3–1, 1 is showing a module failure at node 4 in the VAXBI
card cage attached by the DWMBB module in slot D of the XMI. The failure
at 2 is showing a failure of the DWMBB attached through node E on the
XMI.
In this particular example, the failure at 1 was caused by a DMB32
module. This module was not properly cabled. If you receive failures within
a VAXBI cage, then run diagnostics for the respective modules, if needed.
If you have a DWMBB failure, check the cabling on the backplane
connecting the DWMBB/A and the DWMBB/B modules.
Check the error messages. The message ?004F appears (see 3 ). See the
VAX 6000: Installing Model 500 Processors manual for instructions on how
to set the system serial number and how to set power to the proper value.
For additional information on self-test, refer to the VAX 6000 Model 500
Service Manual.

Module Handling

A–1

A.1 Handling Modules
Handle the processor modules with care. The technology
used on the 6000 series modules is more vulnerable to static
than past technology. Also, these modules have 25 mil leads
to the chips; these leads are very small, close together, and
easily bent.

Figure A–1: Holding 6000 Series Processor Modules

msb-0228-90

A–2 VAX 6000 XMI Conversion Manual

The 6000 series modules require careful handling. Prepare yourself and
the work area before handling these modules. Roll up your sleeves and
remove any jewelry. Figure A–1 shows the proper way to hold the module.
Follow these handling procedures to avoid damaging the processor modules:
1. Always wear an antistatic wrist strap.
2. Before removing the module from its ESD box, place the box on a clean,
stable surface.
Be sure the box will not slide or fall. Never place the box on the floor.
And be sure no tools, papers, manuals, or anything else that might
damage the module is near it. Some components on this module can
be damaged by a 600-volt static charge; paper, for example, can carry
a charge of 1000 volts.
3. Hold the module only by the edges, as shown in Figure A–1.
Do not hold the module so that your fingers touch any 25 mil devices,
leads, or XMI fingers. Be sure you do not bend the module as you are
holding it.
4. Be sure nothing touches the module surface or any of its components.
If anything touches the module, components or leads can be damaged.
This includes the antistatic wrist strap, clothing, jewelry, cables,
components on other modules, and anything in the work area (such
as tools, manuals, or loose papers).

msb-0372R-90

A–4 VAX 6000 XMI Conversion Manual

You must take special precautions when moving the processor modules in
or out of the XMI card cage.
1. Be sure, when inserting a module in or removing it from the XMI card
cage, that no part of the module comes in contact with another module
or a cable.
2. When you swap out a module, place it in an ESD box or on an ESD mat
before you install the new module.
If you place the module on an ESD mat, make sure the mat is on a
stable, uncluttered surface, with side 1 of the module facing up (the side
with the heat sinks). Do not put it on the top of the system cabinet. And
never slide the module across any surface. The leads on the components
are fragile and can be damaged by contact with fingers or any surface.
3. Hold the XMI card cage handle while removing or inserting the module.
If it is not held in place, the handle can spring down and damage the
module.
4. When inserting a module in the card cage, grasp it as shown in
Figure A–2 or in Figure A–3, being careful not to touch any 25 mil
devices, and slide it slowly and gently into the slot.
5. Do not attach the repair tag to the module.
Place the repair tag in the plastic bag attached to the bottom of the
ESD box. Allowing the repair tag to come in contact with the module
can cause damage to a component.

Power-Up Troubleshooting Procedures
This appendix gives detailed power-up troubleshooting procedures.
The H7206-B diagnostic LEDs can help you troubleshoot the system.
Table B–1 lists the meaning of each LED.

Table B–1: H7206-B Diagnostic LEDs

+14V logic bias is okay

NOTE: LEDs 5 and 6 will always be lit in Standby mode since the VAXBI
side is off in this key position. The H7206-B diagnostic LEDs may not
indicate problems with regulators if the status cables are not correctly seated.

Power-Up Troubleshooting Procedures B–1

B.1 Power-Up with Inhibit Cable and XMI-1 Modules
Installed
When the key switch is turned from Off to Standby with the H7242 inhibit
cable installed and with no Model 500 CPUs, the following H7206-B LEDs
are lit:
•

L1 (green) - +14V bias present

•

L5 (red) - VAXBI H7215 fault

•

L6 (red) - VAXBI H7214 fault

•

L8 (red) - XMI-1 module in XMI-2 card cage

The green LED on the XMI-side H7214 power regulator should be lit. The
green LED on the H7242 power regulator should be off; it will always be
off with the H7242 inhibit cable installed. If the power control/status cable
is installed upside down, the XMI side will shut down almost immediately.
The green LEDs on both VAXBI power regulators will be off.
When the key switch is turned from Standby to Enable or Secure, L5 and
L6 on the H7206-B should go out (see Figure 3–8), and the green LEDs
on each VAXBI power regulator will light. L8 will remain on, since XMI-1
modules are installed in the XMI-2.
If L5 and L6 do not go out, check that the control/status cable (17-0166601) for the VAXBI side is installed correctly. If it is not connected, LEDs
L5 and L6 (VAXBI H7215 and H7214 failure) on the power and logic unit
will be off, since the active pulldown to turn the LEDs off comes from the
regulators.
Check that the +300V bulk power cable to the VAXBI side is connected at
the regulators and at the H7206-B (connector J3).
WARNING: Never make or break +300V connections with power applied.
Disconnect input power and wait 2 minutes to allow the filter capacitors
to discharge (bleed down) to zero volts before making or breaking any
connections.
If L9 is lit, indicating a fault, and the XMI side is okay, check the interlock
2-pin Mate-N-Lok connector under the H7215 and recheck the VAXBI
door (listen for the faint click of the microswitch). Correcting the door
or interlock switch connection should automatically clear the fault without
your having to recycle power at the key switch or having to press the H7206B reset switch.

B–2 VAX 6000 XMI Conversion Manual

B.2 Normal Operation with Model 500 CPUs and No
Inhibit Cable
Normal system operation is with Model 500 CPUs and MS65A memory
modules installed, no H7242 inhibit cable, and no XMI-1 modules. When
power is supplied to the system under these conditions and the key switch
turned to Standby, the following H7206-B LEDs are lit:
•

L1 (green) - +14V bias present

•

L5 (red) - VAXBI H7215 fault

•

L6 (red) - VAXBI H7214 fault

The green LEDs on the XMI-side H7214 and H7242 power regulators should
be lit. The green LEDs on both VAXBI power regulators will be off. When
the key switch is turned from Standby to Enable or Secure, L5 and L6
on the H7206-B should go out and the green LEDs on each VAXBI power
regulator will light.
If L5 and L6 do not go out, check that the control/status cable (17-0166601) for the VAXBI side is installed correctly. If it is not connected, LEDs
L5 and L6 (VAXBI H7215 and H7214 failure) on the power and logic unit
will be off, since the active pulldown to set the LEDs off comes from the
regulators.
Check that the +300V bulk power cable to the VAXBI side is connected at
the regulators and at the H7206-B (connector J3).
WARNING: Never make or break +300V connections with power applied.
Disconnect input power and wait 2 minutes to allow the filter capacitors
to discharge (bleed down) to zero volts before making or breaking any
connections.
If L9 is lit, indicating a fault, and the XMI side is okay, check the interlock
2-pin Mate-N-Lok connector under the H7215 and recheck the VAXBI
door (listen for the faint click of the microswitch). Correcting the door
or interlock switch connection should automatically clear the fault without
your having to recycle power at the key switch or having to press the H7206B reset switch.
Since everything but the H7242 has been checked out, check the H7242, its
connection to the H7206, and any sequencing activity between the H7242
and H7214. Check the control/status cable to the H7242 and reseat if
necessary. Check that the +300V bulk power cable is attached to the H7242.
If the H7242 connection is not properly made, no other regulators on the
XMI side should run since the +300V is daisy chained through etch on the
H7214 and H7242 at the +300V input connector (that is, if the H7242 is

Power-Up Troubleshooting Procedures B–3

not connected, then the other two regulators will also be disconnected even
if their cables are properly attached).
If one power regulator fails to power up, the other one will shut down also.
Check the XMI H7214 and XMI H7242 red LEDs (L3 and L4) to determine
if the H7214 led to the shutdown of the H7242.
Note that the XMI AC LO L, XMI DC LO L, and XMI RESET L signals are
sent to the XMI backplane by way of the XTC module. The H7206 delivers
the AC BULK SENSE and DC OK H signals to the XTC through cable
17-01498-01. If this cable is not in place, the H7206-B should not be able
to respond to key switch action (should never power up the H405 contactor
or deliver output voltages (+24V bias or bulk +300V).
