1-2 Introduction

Figure 1-1 shows the quadrant designation for system and expander cabinets. XMI PIUs are installed in the bottom of either cabinet with the card
cages and power regulators installed in the front. The XMI PIU requires
two quadrants of space: quadrants 1 and 2 if the card cage is installed on
the left, and quadrants 3 and 4 if it is installed on the right when you face
either cabinet. From the front of either cabinet the XMI PIU must be to
the left of a VAXBI PIU if one is installed.
The following rules apply:
1.

XMI PIUs in cabinets
a. XMI PIUs are placed in the bottom of cabinets.
b. A maximum of two XMI PIUs can be placed in a cabinet.
c. A maximum of four XMI PIUs can be placed in a system.

XMI PIU Configuration Rules
a. Each XMI PIU occupies two of the bottom quadrants: 1 and 2 or 3
and 4. The XMI PIU occupies quadrants 1 and 2 when a VAXBI
PIU is installed.
b. The XMI bulkhead has 20 dual I/O panels. One is used for the I/O
cable from the IOP.

XMI Configuration Rules
a. Of the 14 slots on the XMI, 12 are available for I/O devices. Two
slots are reserved; slot 7, for the T2030-YA, the clock module, and
slot 8, for the T2028-AA, the DWLMA module.
b. The first option on an XMI must reside either in slot 1 or slot 14 to
terminate the bus. If the option is a two-module option, the module with the XMI corner must be in slot 1 or 14.
c. If the cabinet has a VAXBI PIU, the T2018 module (XBIA+) must
reside in slot 1 of the XMI backplane.

Introduction 1-3

1.2 XMI PIU Kit Contents
The DWLMA XMI PIU option has two variants: one for a system
cabinet and the other for an expander cabinet. The only difference between the two kits is the length of the cable that goes from
the IOP in the system cabinet to the I/O bulkhead. Figure 1-2
shows the XMI PIU assembly.

The contents of the two kits follows:
•

The XMI PIU card cage assembly consists of two major pieces:
— The card cage itself with the power regulators which plugs into
either cabinet from the front. The clock module is already installed
in the card cage.
— The rear cable enclosure, consisting of the enclosure and the bulkhead panel door that plugs into either cabinet from the back. Figure 1-2 shows the two pieces. (See Section 2.2 for installation.)

•

The DWLMA adapter module is placed in slot 8 of the XMI. (See Section 2.5 for installation.)

•

The 4 to 1 cable is placed between the I/O bulkhead and the XMI
backplane. (See Section 2.3 for installation.)

Introduction 1-5

Chapter 2
Installation of the XMI PIU
Five tasks are necessary to install an XMI PIU. They are:
•

Preparing the Cabinet

•

Installing the Card Cage Assembly

•

Installing the 4 to 1 Cable

•

Installing the IOP Hose Cable

•

Installing the DWLMA

Installation of the XMI PIU 2-1

2.1 Preparing the Cabinet
After you determine the XMI PIU quadrant location, you must remove the airflow plates located below the blower and above the
quadrants you will be using.

Figure 2-1

Airflow Plate

Front

Rear
BXB-0412B-93

2-2 Installation of the XMI PIU

Take the following steps to prepare the system:
1.

Perform an orderly shutdown of the system.

Turn the keyswitch to Disable.

Determine which quadrants will house the XMI PIU (in the system or
expander cabinet). See Section 1.1 for placement rules.

Open the front and rear doors of the cabinet. If you are installing the
XMI PIU in an expander cabinet, you will need access to the rear of
the system cabinet also.

Shut the circuit breaker on the AC power box off by pushing down on
the breaker. The AC power box is above the blower and to the left in
both cabinets.

If you are installing the PIU in an expander cabinet, drop the skirts
below the rear doors of both cabinets.

Remove the two airflow plates from the front and rear of the cabinet
(see Figure 2-1). These slide out of the cabinet and should be labeled
and saved. (If the PIU is removed, these plates must be replaced to
maintain proper airflow in the cabinet.)

The bulkhead door on the rear cable enclosure of the XMI PIU comes
hinged on the left. If the XMI PIU is placed in the cabinet on the left
when viewed from the rear (quadrants 3 and 4), the door should be
hinged on the right. If you need to change the hinges, do that now,
following the procedure in Appendix A.

Installation of the XMI PIU 2-3

2.2 Installing the Card Cage Assembly
The BA651-AA card cage assembly consists of two parts: the card
cage assembly with the clock module and power regulators, and
the rear cable enclosure. First install the card cage assembly and
then the rear enclosure.

BXB-0405D-93

2-4 Installation of the XMI PIU

To install the XMI PIU:
NOTE: Before installing the PIU, inspect the electromagnetic interference
(EMI) gaskets; return the option if they are damaged.
1.

Ground yourself to the cabinet with the antistatic wrist strap from the
Electrical Safety Kit.

Place the XMI card cage half into the cabinet by lining up the rollers
on the PIU with the slides in the cabinet. Now push the card cage into
the cabinet until it seats.

Line up and only slightly tighten the two captive screws (slotted) at
the top of the PIU, 3 in Figure 2-2.

Install the two Phillips head screws at the bottom of the card cage securing the PIU to the cabinet, 4 in Figure 2-2. Tighten the two captive screws mentioned in step 3 to 27 inch-pounds.

Be sure the I/O bulkhead door opens in the correct direction before
proceeding to step 6. See Section 2.1, step 8.

At the back of the cabinet, install the rear cable enclosure lining up
the rollers on the PIU with the slides in the cabinet.

Line up and only slightly tighten the two captive screws (slotted) at
the top of the enclosure.

Install the two Phillips head screws at the bottom of the cable enclosure securing the back of the PIU to the cabinet. Tighten the two captive screws mentioned in step 7 to 27 inch-pounds. Tightening these
screws compresses the EMI gaskets between the two halves.

Installation of the XMI PIU 2-5

2.3 Installing the 4 to 1 Cable
The 4 to 1 cable, part number 17-03061-01, is installed between the
XMI backplane and the I/O bulkhead.

2-6 Installation of the XMI PIU

The 4 to 1 cable is labeled for easy, correct installation. The bulkhead end
of the cable is easily identified by the bulkhead plate and the receptacle for
the IOP cable. The XMI backplane end has four connectors labeled DL,
DR, EL, and ER.
To install the cable:
1.

Remove the plastic shield from the XMI backplane.

Figure 2-4 shows the I/O bulkhead door. If the XMI PIU is installed
on the left, the bulkhead plate of the 4 to 1 cable goes in A5; if it is on
the right, the bulkhead plate goes in A1. Select and remove the correct panel from the I/O bulkhead door.

The IOP connector is offset on the bulkhead plate. When the plate is
installed in a system cabinet, the connector is to the left of center.
When the plate is installed in an expander cabinet, the connector is
right of center. Install the bulkhead end of the 4 to 1 cable in the
bulkhead door by passing the cables through the door and secure by
using the two screws removed from the plate in step 2.

The DWLMA adapter goes in slot 8. Slot 7 is used for the clock module and has no connectors. Slot 8 is to its right on the XMI backplane.
See Figure 2-3.

Install the cable marked DL into the left receptacle of row D, slot 8.

Install the cable marked DR into the right receptacle of row D, slot 8.

Install the cable marked EL into the left receptacle of row E, slot 8.

Install the cable marked ER into the right receptacle of row E, slot 8.

Replace the plastic shield.

To verify that the XMI PIU is functioning properly:
1.

Insert a supported XMI option into either slot 1 or 14 to terminate the
XMI bus. The module you install must have an XMI corner on it.

Power on the system and examine the self-test results to determine
whether the XMI PIU passes. Example 3-1 shows sample self-test results. Two XMIs are shown in the example.
The + at the end of the line marked
to the C0 hose is functioning.

shows that the XMI connected

The − at the end of the line marked
to the C1 hose is not functioning.

shows that the XMI connected

Lines C0, C1, C2, and C3 correspond to IOP ports (see Figure 3-1).
In Example 3-1 the XMI connected to IOP port C1 is failing. If the C
line indicates a problem, check all the cabling and retest. If the problem continues, follow the troubleshooting procedures in your system’s
Advanced Troubleshooting manual.
To verify that each slot in the backplane works, do the following:
1.

Install a "known good module" in the slot you wish to test.

Power on the system.

Examine the self-test results to determine whether the slot is working.

Repeat steps 1 through 3 for each slot.

If a slot fails, return the option. If the XMI PIU passes verification, continue with the installation of XMI options.

Appendix A
Moving Hinges on the Bulkhead
Door
The XMI plug-in unit comes with the rear bulkhead door hinged at the left.
The door opens properly when the enclosure is in the rear right quadrant
(Q2). When the enclosure is in the rear left quadrant (Q4), the door should
be hinged on the right so that the hose is moved as little as possible when
the door is opened. This appendix describes how to change the hinges.

Moving Hinges on the Bulkhead Door A-1

A.1 Moving the Hinges of the Bulkhead Door
In addition to moving the hinges from one side of the bulkhead
door to the other, the EMI finger stock and the plunger fasteners
must be moved.

Moving Hinges on the Bulkhead Door

Figure A-1 shows two bulkhead doors; one hinged left and the other hinged
right. Follow these steps when moving the hinges on the doors from one
side to the other. The steps assume the door is hinged left.
1.

Remove the door by unscrewing the shoulder bolt hinges at the top
and bottom. Note that the nylon washers are between the enclosure
and the door.

Move the plastic spacer on the bottom right flange of the enclosure to
the bottom left of the enclosure (where the bottom hinge used to be).

Remove the EMI finger stock from the top flange on the enclosure.

Using two 3/8 inch wrenches, remove the plunger fastener on the top
flange of the enclosure and reinstall it one hole to the left of its original location. Put the plunger in its hold open position to secure the
"top" wrench and hold the "nut" under the flange with the other
wrench and remove or tighten.

Reinstall the EMI finger stock.

Remove the EMI finger stock from the bottom of the door.

Using two 3/8 inch wrenches remove the plunger fastener on the bottom of the door and reinstall it one hole to the left of its original location. Put the plunger in its hold open position to secure the "top"
wrench and hold the "nut" under the flange with the other wrench and
