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.

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.

19. Position the CPU module halfway into its slot so the cables can reach the
daughter card.
20. Connect the DSSI bus 2 and bus 3 cable connectors to the corresponding
connectors on the DSSI daughter card. The connectors are keyed and
marked ‘‘Bus 2’’ and ‘‘Bus 3’’ in the etch for proper assembly. Refer to
Figure 1–10. Make sure the connectors lock in place.
21. Ensure the DSSI cables are out of the way so you can insert the CPU
module into the backplane connector.
Suggestion
Service loops should be created with the cable slack to allow the CPU
module/DSSI daughter card to slide into and out of the slot easier.
Loop the bus 3 cable toward the front of the unit touching the mother
board and loop the bus 2 cable toward the back of the unit touching the
mother board.

22. Push the CPU module into its slot and lock it in place.
23. Reinstall the memory modules into their original slots starting from left to
right. Refer to the Suggestion above to get the DSSI cables out of the way.
It may be necessary to manually move the DSSI cables while installing the
first memory module.
24. Reinstall the Q–bus options or blank panels. Refer to the chart you made
before you removed the options for reference.
25. Reconnect the internal cables to the H3604 console module. Close and lock
the H3604 console module.
Note
Ensure the H3604 console module backplane power card is fully
inserted before installing the H3604 console module cover.

26. Reconnect any cables belonging to the H3604 console module.
27. Reverse the ISE removal procedure to reinstall the ISEs. Ensure that the
original ISE control panel goes with each ISE.
28. If you installed an expander unit, connect the expander cable at this time.
Refer to the expander documentation.
29. Attach a DSSI terminator (12–29258–01) to any unused Bus 2 or Bus 3
bulkhead port.
30. Turn on the power to the system and expander boxes, if any. Have the
customer perform a VMS boot to the system. Run diagnostics to verify
system operation.
31. Check the power up procedure to determine which ID plugs are used.
Until overridden by the SET DSSI_ID console command, DSSI bus 2 and 3
will assume the same IDs as Bus 0 and 1, respectively. You can change
the DSSI ID by the SET DSSI_ID console command. Refer to the VAX 4000
Model 500A/600A/700A Operation manual to set and examine DSSI device
parameters from console mode.
32. Have the customer reinstall the system backup information. This is
optional.

15. If you are using Q–bus expansion, do the following:
a. Install a filler panel (74–33507–01) into slots 11 and 10.
b. Install a Q–bus grant card (M9047) into the filler panel in slots 11 and
10.
16. Pull all the cables’ slack into the CPU area. Arrange the four cables
downward in the card cage area.
17. Secure each bulkhead to the card cage using its captive screws.
18. Install the DSSI bus daughter card (54–20569–01) on the CPU module.
a. Remove the DSSI daughter card from its packaging.
b. Open the ejector handles on the daughter card connectors.
c.

Turn the daughter card so the component side is facing down.

d. Align the connector on the daughter card with the corresponding
connector on the CPU module.
e.

Align the standoff holes on the daughter card with the standoff posts
on the CPU module.

Push the daughter card onto the CPU module until it locks in place.

g. Check to ensure that the connectors are firmly seated. Refer to
Figure 2–7.

19. Place the CPU module into its slot.
20. Connect the DSSI bus 2 and bus 3 cable connectors to the corresponding
connectors on the DSSI daughter card. The connectors are keyed and
marked ‘‘Bus 2’’ and ‘‘Bus 3’’ in the etch for proper assembly. Refer to
Figure 2–8. Make sure the connectors lock in place.
Suggestion
Service loops should be created with the cable slack to allow the CPU
module/DSSI daughter card to slide into and out of the slot easier.
Loop the bus 3 cable toward the top of the unit touching the CPU board
and loop the bus 2 cable toward the bottom of the unit touching the
CPU board.

21. Push the CPU module into its slot and lock it in place.
22. Reinstall the memory modules into their original slots starting from left to
right. Refer to the Suggestion above to get the DSSI cables out of the way.
It may be necessary to manually move the DSSI cables while installing the
first memory module.
23. Reinstall the Q–bus options or blank panels.
24. Reconnect the internal cables to the H3604 console module. Close and lock
the H3604 console module.
NOTE
Ensure the H3604 console module backplane power card is fully
inserted before installing the H3604 console module cover.

25. Reconnect any cables belonging to the H3604 console module.
26. If you installed an expander unit, connect the expander cable at this time.
Refer to the expander documentation.
27. Attach a DSSI terminator (12–29258–01) to any unused Bus 2 or Bus 3
bulkhead port.
28. Turn on the power to the system and expander boxes, if any. Have the
customer perform a VMS boot to the system. Run diagnostics to verify
system operation.
29. Check the power up procedure to determine which ID plugs are used.
Until overridden by the SET DSSI_ID console command, DSSI bus 2 and 3
will assume the same IDs as Bus 0 and 1, respectively. You can change
the DSSI ID by the SET DSSI_ID console command. Refer to the VAX 4000
Model 500A/600A/700A Operation manual to set and examine DSSI device
parameters from console mode.
30. Have the customer reinstall the system backup information. This is
optional.
