Preparation

•

The VAXBI PIU is installed in quadrants 3 and 4.

•

An XMI PIU is required in the cabinet, in quadrants 1 and 2.
In both system and expander cabinets, looking at the cabinets from the
front, the VAXBI PIU is on the right and the XMI PIU is on the left. If
the cabinet does not have an installed XMI PIU, stop here and install
one. Then proceed.

•

Use the DWMBB-LA PIU kit to install the PIU assembly and connect
one six-slot bus. This leaves five slots for other modules. Physically,
the VAXBI contains two six-slot card cages.

•

Use the DWMBB-LB upgrade kit to connect the second six-slot card
cage. This provides two six-node VAXBI buses operating independently.

•

A system can support a maximum of six six-slot VAXBI buses (two in
each expander cabinet and two in the system cabinet).

NOTE: When you install a DWMBB-LA or -LB kit, an additional 48V
power regulator may be required to supply the DWMBB modules
and other VAXBI modules. This depends on system configuration
and power requirements. This determination should be made at
the time of order (see the current Systems and Options Catalog).
Also, some unusual combinations of VAXBI options may strain the
power supply in the VAXBI PIU. Maximum ampacities are listed
in Appendix A of this book.

For more information:
Appendix A, VAXBI PIU Ampacities

Preparation 1-5

1.3 Get Ready
Set up your work space, unpack the option kit and check the contents against Table 1-1 or Table 1-2. Prepare the system for shutdown. You will need a Phillips head and a flathead screwdriver.

Preparation

Chapter 2
Installing the Enclosures
NOTE: The DWMBB VAXBI option requires an XMI PIU in its cabinet to
operate. If your system or expander cabinet does not have an XMI
PIU installed in quadrants 1 and 2, stop here and install the
DWLMA XMI PIU first. Then proceed.
If you are installing the DWMBB-LA VAXBI PIU kit, follow the instructions in this chapter. If you are installing only the DWMBB-LB kit, skip
to Chapter 3.
This chapter describes installing the VAXBI PIU enclosures. The front enclosure houses the power regulators and the VAXBI card cages. The rear
enclosure includes the I/O bulkhead door and an EMI cable shield. Sections in this chapter include:
•

Remove the Airflow Plates

•

Install the Front Card Cage Enclosure

•

Install the Rear Cable Enclosure

•

Prepare Cable Routing

For more information:
DWLMA XMI PIU Installation Guide

Installing the Enclosures 2-1

2.1 Remove the Airflow Plates
Remove the front and rear cabinet airflow plates (70-29365-01) located below the blower in quadrants 3 and 4. The plates direct airflow to other components when a quadrant is empty.

Installing the Enclosures

The DWMBB-LA VAXBI PIU kit includes a front enclosure housing the
card cage and power regulators, a rear I/O cable enclosure with bulkhead
door, an EMI cable shield, and signal cables. There are two modules in the
XMI-to-VAXBI DWMBB adapter set.
Begin installation by removing the airflow plates in quadrants 3 and 4.
1.

Using a Phillips screwdriver, remove the two screws that hold the airflow plate to the cabinet frame (see 2 in Figure 2-1).

Save the two screws you remove. You will need these screws for securing the bottom of the enclosures to the frame.

Slide the front and rear airflow plates out of the cabinet.

Label and save the airflow plates. If a PIU is removed for maintenance or a change in system configuration, these plates must be reinstalled to ensure proper system operation.

Installing the Enclosures 2-3

2.2 Install the Front Card Cage Enclosure
The PIU has two halves. First install the enclosure housing the
VAXBI card cage and power regulators. Work from the front of the
cabinet installing the enclosure in quadrant 3.

Installing the Enclosures

BXB-0450-93

The PIU consists of two enclosures: a front enclosure which houses the
card cage and power regulators, and a rear enclosure with the I/O bulkhead door. Install the front enclosure first.
1.

Holding the front enclosure with two hands, set the bottom into quadrant 3. The front enclosure is heavier than the rear enclosure.

Tilt the top of the enclosure up into the quadrant space, aligning the
rollers with the slides in the cabinet.

Push the enclosure in until it stops.

Lightly screw in the two top captive screws of the enclosure to hold it
in place (see 4 ). Do not tighten them yet. You need some play in
the alignment for the next step.

Take the two Phillips screws you removed from the airflow plate and
screw in the bottom of the enclosure to the cabinet frame (see 5 ).
Tighten these screws.

Tighten the top two captive screws. Tightening these screws compresses the EMI gasket between the front and rear enclosures.

Installing the Enclosures 2-5

2.3 Install the Rear Cable Enclosure
Working from the rear of the cabinet, install the rear cable enclosure in quadrant 4. Watch the power cables on the backplane of
the front enclosure as you install the rear half.

The rear half of the PIU houses the I/O bulkhead door and cables. After
you have installed the front enclosure, install the rear enclosure.
NOTE: Take care that the power regulator cables on the rear of the front
enclosure do not get jammed between the units. Carefully arrange
these cables as you guide the rear enclosure into position.
1.

Holding the rear enclosure with two hands, set the bottom into quadrant 4.

Tilt the top of the enclosure up into the quadrant space, aligning the
rollers on the enclosure with the slides in the cabinet.

As you push the unit in, arrange the power regulator cables on the
front enclosure so they do not get jammed between the enclosures.

Push the rear enclosure in until it stops.

Lightly screw in the two top captive screws of the enclosure to hold it
in place (see 5 in Figure 2-3). Do not tighten them yet. You need
some play in the alignment for the next step.

Take the two Phillips screws you removed from the airflow plate and
screw in the bottom of the enclosure to the cabinet frame (see 6 ).
Tighten these screws.

Tighten the top two captive screws. Tightening these screws compresses the EMI gasket between the front and rear enclosures.

Installing the Enclosures 2-7

2.4 Prepare Cable Routing
Remove the dual panel on the center wall inside of the VAXBI and
XMI rear enclosures. Install the EMI cable shield, part number 7031069-01, in the XMI rear enclosure facing toward the VAXBI side.

Installing the Enclosures

The signal cables connecting the VAXBI and XMI backplanes must route
between the rear cable enclosures. On both rear enclosures, remove the
dual panel on the side of the enclosures toward the center of the cabinet as
follows:
1.

Open the I/O bulkhead doors.

In the XMI rear enclosure, remove the two small hexnuts from the
dual panel on the side toward the VAXBI enclosure. Save these
hexnuts; you will use them in step 5.

Holding onto the lip of the plate, pull it toward you and then move it
up and down until you can release it from the hexnuts. Remove and
store the panel.

Repeat steps 2 and 3 for the panel inside the VAXBI rear enclosure on
the side toward the XMI.

Place the EMI cable shield in the XMI enclosure on the mounted
screws on the side toward the VAXBI rear enclosure. Place the shield
inside the XMI so that the finger stock protrudes through the XMI
sidewall and makes contact with the VAXBI enclosure. Replace the
hexnuts, top and bottom.

You are ready to route the cables.

3-2 Installing the DWMBB Adapters

For DWMBB-LA Kits:
1.

Install the four ends of the signal cable set (17-01897-03) at XMI slot
1, segments D and E, with the red stripe up. If an XMI module is already installed in slot 1, that option must be moved to another slot.

Route the cables from XMI card cage slot 1 through the EMI gasket in
the I/O enclosure cable openings to VAXBI card cage slot 7.

Install the other ends of the cables (17-01897-03) on the VAXBI card
cage slot 7, segments D and E with the red stripe up.
For DWMBB-LB Kits:

Install another cable set (17-01897-03) at XMI slot 2, as in step 1.

Connect the cable set for VAXBI slot 1, segments D and E with the red
stripe up.
For Both Kits:

Check that a unique node ID is installed for each VAXBI slot and that
the node plugs are fully inserted.
VAXBI node ID plugs are installed at manufacturing and normally assigned in consecutive order, with slot 1 = node ID 1 and slot 12 = node
ID 12. You may change the IDs; as long as the node IDs are unique
within a bus, the actual values do not matter.

Installing the DWMBB Adapters 3-3

3.2 Install the DWMBB Adapters

4-2 Acceptance and Troubleshooting

SYS SN = GAO1234567
BXB-0030R-93

Reinstall rear cabinet skirt.

Pull the AC power circuit breaker handle up to turn the circuit
breaker on.

Close the cabinet doors.

Turn the control panel keyswitch to the Enable position; the system
powers up and runs self-test.

In Example 4-1:
•

Self-test runs at power-up.

•

The C0 XMI line gives status on XMI adapters. Because this XMI has
two DWMBB/A adapters connecting to VAXBI buses, the next two
lines report VAXBI adapter self-test status. Two VAXBI buses is the
maximum number allowed in a cabinet.

•

The first VAXBI line indicates it is connected by the XMI DWMBB/A
adapter installed in XMI slot 1, which is passing self-test. The VAXBI
DWMBB/B adapter is in VAXBI node 7 and this bus has node numbers
7 though 12. See 1 .

•

The second VAXBI line indicates it is connected by the DWMBB/A
adapter installed in XMI slot 2, which is passing self-test. The VAXBI
DWMBB/B adapter is in VAXBI node 1, and this bus has node numbers 1 though 6. See 2 .

Acceptance and Troubleshooting 4-3

4.2 Check DWMBB Module LEDs
In addition to checking the self-test display, check the DWMBB
module LEDs.

4-4 Acceptance and Troubleshooting

Also check the DWMBB module LEDs.
The DWMBB/A XMI module (T2018) has two LEDs: the upper LED is yellow and lights to indicate self-test passed and the lower LED is red and
lights when there is an error or self-test failure.
The DWMBB/B VAXBI module (T1043) has a yellow self-test LED visible
from the front of the card cage. This LED lights when the module passes
self-test. A second yellow self-test LED is on the VAXBI corner, deeper in
the cabinet. The DWMBB/A does not have a red error LED.
If you are having intermittent or failing status, check the XMI power regulators LEDs.

4-6 Acceptance and Troubleshooting

Enter a show configuration command to check module status.

The DWMBB/A XMI adapter in slot 1, dwmbb0, passed self-test.

The DWMBB/A XMI adapter in slot 2, dwmbb1, also passed self-test.

Acceptance and Troubleshooting 4-7

4.4 VAXBI Troubleshooting
Check the items listed in Table 4-1 if the system fails to power up.

Table 4-1 VAXBI Troubleshooting Checklist
Symptom

Possible Cause

No power to PIU

Power regulator LEDs not on
(48V and MOD OK LEDs)
AC circuit breaker not on
Switch on power regulator not set
to Enable position

Intermittent module response

Poor contact at connector
Loose cabling at backplane

Module is not reported
on self-test results

Loose cabling at backplane
System not configured correctly
Cables are installed incorrectly
(check D and E segments; the red
stripe should be on top)
CPU console code out of revision

4-8 Acceptance and Troubleshooting

At power-up, the yellow LEDs on the T1043 and T2018 modules should be
ON. If the red LED on the T2018 module is ON, the module failed self-test.
If you receive intermittent module response, or the module does not show
up on self-test as being present, make sure the modules are seated properly, a node ID plug is in place, and the backplane cabling is correct.
Modules may fail self-test because of poor contact at the connector. A thorough cleaning of the gold pads on the module and of the connector in the
card cage corrects this contact failure. If the connections seem to be faulty,
clean the contact areas of the connector and module. Table 4-2 lists tools
and cleaning supplies.

The maximum PIU current is net, after subtracting the current used by the two sets of
VAXBI terminators and the two DWMBB options. Each T1043 module draws 6.0 A of
+5.0 V and 0.1 A of −12.0 V.

In the VAXBI PIU, the +5 VBB and +5.0V buses are tied together. Both buses are supplied
from the same 136.0 A output.

Current requirements for typical VAXBI options are shown in Table A-2.
For other VAXBI options, consult the VAXBI Options Handbook (EB32255-46) or information from the option’s vendor.
