Installation
This chapter describes how to upgrade a VAX 4000 (BA440-based) system with
the dual DSSI bulkhead assemblies.
Caution
Modules can be damaged by static discharge if an antistatic wrist strap
is not worn or an antistatic mat is not used during handling. The wrist
strap and mat are in the antistatic kit in the Digital Services toolkit.
1.1 System Requirements
The system must have VMS software, Version 5.5–2H4, VMS 6.1, or later to
support the KFDDB–AF with the KA681, KA691, KA692, or KA694 CPU. Also,
the system must have a Rev. K01 or higher BA440 backplane (54–19354–01).
The DSSI daughter card is only supported on KA681, KA691, KA692, and
KA694 CPUs.
1.2 Kit Inventory
The DSSI upgrade kit contains the following items:
• 1 Installation document (EK–VV4SY–IG. B01)
• 1 Dual DSSI daughter card (54–20569–01)
• 2 DSSI bulkhead assemblies with cable attached (70–22860–01)
• 2 Bus 2 labels (36–26883–D4)
• 2 Bus 3 labels (36–26883–D3)
• 2 Grant cards (M9047–00)
• 2 Filler panels (74–33507–01)
• 4 DSSI terminators (12–29258–01)
Installation 1–1

• 2 cable spacers (74–49137–01)
1.2.1 Unpacking the Kit
Follow these steps when unpacking the kit.
1. Make sure there is no external damage to the shipping container, such as
dents, holes, or crushed corners.
2. Unpack the upgrade kit and check its contents against the content listing.
3. Do not unpack the DSSI daughter card at this time.
4. If any item is missing or damaged:
a. Contact the customer’s sales representative.
b. Contact the customer’s delivery agent.
1.2.2 Before Installing the Kit
Before installing the kit:
1. It is the customer’s responsibility to back up the system disk before the
Digital Services representative arrives. This is optional.
2. Run MDM diagnostics to verify system operation. This is optional.
3. Perform a VMS shutdown of the system before installing the kit.
1.3 Installing the Kit
To install the upgrade kit, do the following:
Note
The ISE figures throughout these steps show the RF-series variety.
Handle ISEs with care. Dropping or bumping the ISE can damage the
disk surface. Carry or hold the ISEs by their metal brackets to avoid
damaging the drive module.
The possible items occupying this space are as follows:
Single ISE — 1 OCP cable to remove
Dual ISE — 2 OCP cables to remove
Blank bezel — No cables to remove
1–2 Installation

1. Unlock the front door by turning the front door key switch to the bottom
position. Open both access doors simultaneously. Turn off the power switch
on the power supply.
2. To make the DSSI installation easier, it is suggested that you remove the
three ISEs (or blank bezels) starting from left to right. Refer to Figure 1–1.
3. If you choose to remove the ISEs, follow the alphabetized instructions
below. If you choose not to remove the ISEs, go to Step 4.
a. Loosen the single captive Phillips screw that secures the ISE front
panel (Figure 1–1A).
b. Separate the ISE front panel from the enclosure, being careful of the
remote front panel cable, which is connected to the ISE front panel.
c. Unplug the remote front panel cable from the module inside the ISE
front panel and set the front panel aside (Figure 1–1B).
Note
Keep track of which front panel belongs with which ISE, since the ISE
must retain its original bus node ID plug.
d. Loosen the upper and lower captive screws that hold the ISE in place
(Figure 1–1C).
e. Using the upper and lower finger cutouts on the ISE bracket, carefully
pull the ISE out of its backplane connector and slide the drive out of
the enclosure. Support the weight of the ISE as the ISE clears the
enclosure (Figure 1–1C).
Caution
Do not touch the drive module. The drive module contains sensitive
electronic circuitry.

4. Remove all Q–bus bulkheads and modules starting from left to right. Refer
to Figure 1–2.
Note
Create a chart of the module order/placement and external cable
connections to the modules to use as a reference when reinstalling the
modules and cables.
Note
If there is a TK70/TQK70 tape drive/controller present, it is not
necessary to remove the TQK70 cable from the machine. It is easier to
disconnect the cable from the module and remove the module only.

The H3604 console module is to the right of slot 6. Refer to Figure 1–3.
DO NOT remove the DSSI cables that are connected to the front of this
console module.
5. Open the H3604 console module by turning the ¼-turn screws.
6. Swing the hinged panel to the left. Note the position of the internal
cables connected to the H3604 module. Carefully disconnect the flat cable
connected to the CPU.
Note
It is not necessary to disconnect the smaller cable that connects to the
short backplane power card.
7. Remove the H3604 console module door by lifting it up. Lay it down in
front of the enclosure.
8. Remove the memory modules.
9. Remove the CPU module.

the DSSI cable assembly. Refer to Figure 1–4.
11. Attach the other ‘‘bus 2’’ label (36–26883–D4) to the front of the bulkhead
assembly. Refer to Figure 1–4.
12. Attach one ‘‘bus 3’’ label (36–26883–D3) to the Berg connector at the end of
the DSSI cable assembly. Refer to Figure 1–4.
13. Attach the other ‘‘bus 3’’ label (36–26883–D3) to the front of the bulkhead
assembly. Refer to Figure 1–4.

14. Install the DSSI bus 2 bulkhead (70–22860–01). Figure 1–5 shows the
position of the DSSI bulkheads inside the BA440 enclosure.
Configuration a If you are not expanding the Q–bus to another enclosure, install
the DSSI bus bulkheads in slots 12 and 11. See Figure 1–6.
Configuration b If you are expanding the Q–bus to another enclosure, install the
DSSI bus bulkheads in slots 11 and 10, and install the Q–bus
expander module in slot 12 of this enclosure. Install another
Q–bus expander in slot 1 of the other expander enclosure.
Note
A filler panel and a Q–bus grant card must be installed behind each
DSSI bulkhead in configuration b.

1–10 Installation

To route the DSSI bus bulkhead cables:
Note
The easiest way to install the cable is by pulling the connector through
while pushing the cable at the other end.
• Route the bus 2 DSSI cables up through the opening to the left of slot
12 (slot 11 if you are expanding the Q–bus) and dress them through the
card cage/mass-storage divider until they reach the slots for the CPU
module. Keep these cables toward the rear of the divider.
• Push the connector through the rear half of the CPU slot. Refer to
Figure 1–6.
• Route the bus 3 DSSI cables up through the opening to the left of slot
11 (slot 10 if you are expanding the Q–bus) and dress them through the
card cage/mass-storage divider until they reach the slots for the CPU
module. Keep these cables toward the front of the divider.
• Push the connector through the front half of the CPU slot. Refer to
Figure 1–7.
• There are sheet metal partitions that separate the mass-storage
cavities. The cable spacer will be placed on the right sides of the first
and second partitions from the left. Figure 1–8 shows the partitions
and the cable spacer in the installed positions.
The cable spacer is for dressing the cables in a manner so that they do
not restrict air flow through the module card cage.
• Remove adhesive liner from the cable spacer.
• The cable spacer is self-locating. Put the spacer "legs" into the storage
divider as shown in Figure 1–8. The spacer will catch itself into place
at the bottom of the partition.
• Press the spacer against the partition to secure it in place.
• Move the bus 2 cables under the spacer’s rear legs and stack them
vertically.
• Move the bus 3 cables under the spacer’s front legs and stack them
vertically.
• Repeat the previous five steps for the second cable spacer.
Installation 1–11

• Make certain that the bus 2 cables are positioned underneath the
wide sheet metal web that runs the center length (front to back) of the
leftmost mass-storage cavity. This will allow proper air flow through
the module card cage.
Figure 1–8 shows the installed cable spacer and the proper orientation of
the cables behind the spacer legs.
