Installation Procedure 1–1

1.2 Installation Procedure
Follow each step sequentially in the following procedure to unpack and
install the Rack-Mountable VAX 4000 Model 100A system.
Step 1: Prepare the Site
Site preparation involves choosing a suitable location for the system
cabinet. Follow these guidelines when choosing the location:
•

The system unit should be placed where the room temperature
is between 10°C and 35°C (50°F and 95°F) and the humidity is
between 20% and 80% noncondensing.

•

The system unit should be placed at least 1 m (3 ft) away from
heaters, photocopying machines or other operating equipment.

•

The system unit should be placed in a well-ventilated location with
at least 1 m (3 ft) of clear space in the front, rear, and sides to allow
for proper airflow and servicing.
Note
The system is mounted sideways on a slide shelf.
Removable media is accessed on the left side; the
power switch and cable ports are accessed on the
right side.

•

The system unit should not be exposed to direct sunlight or abrasive
particles.

•

The system should be placed within 4.57 m (15 ft) of the console
terminal. (The console terminal is not supplied with the system kit.)
Note
Digital recommends that you DO NOT install the shelf
in the lowest position in the cabinet. Installing and
aligning the system with the bumpers and holes in the
shelf is extremely difficult if the shelf is installed in the
lowest cabinet position.

1–2 Installation Procedure

You must also select the location within the cabinet for the RackMountable VAX 4000 Model 100A. The system requires:
•

22.2 cm (8.75 in) of vertical cabinet mounting space

•

48.3 cm (19 in) of cabinet width mounting space

•

73.66 cm (29 in) minimum of cabinet depth mounting space:
63.5 cm (25 in) for the system
10.6 cm (4 in) for the cables

•

Location of within 2 m (6 ft) of ac power source

The system unit must be mounted within cable routing distances. The
Rack-Mountable VAX 4000 Model 100A is shipped with a 7.58 m (25 ft)
MMJ cable for connection to a console terminal. Refer to the appropriate
documentation for other external option cable length requirements.
Note
The console terminal is not supplied with the system.

Step 2: Unpack the System and Identify the Parts
Note
If your system has already been installed in a cabinet,
refer to Section 4.2 to remove the shipping strap and
bracket, then proceed to Step 9: Check the Power-Up
Test Results.

Make sure that you have all the parts listed on the packing slip(s).
1. Unpack the carton containing the Rack-Mountable VAX 4000 Model
100A system. Ensure that all parts listed in Figure 1–1 and
Figure 1–2 have been received and are undamaged.

B.5 Connecting a Peripheral Cable to the
Asynchronous Modem Control Port
You can connect peripherals that use EIA-232 connectors to the
asynchronous modem control port (port 2) on the back of the system
unit. Alternatively, the supplied EIA-232 to DEC423 adapter (H8575-A)
allows you to connect peripherals that use DEC423 connectors. To
connect a peripheral to the asynchronous modem control port, refer to
the following steps:
1. If you are connecting a peripheral using EIA-232 cables:
a. Set the ON/OFF switch on the peripheral to the OFF (O)
position.
b. Connect the 25-pin D-sub connector of the peripheral cable to
the asynchronous modem control port.
c.

If the connector has screws on either side, tighten them using a
small screwdriver.

d. Connect the other end of the peripheral cable to the correct port
on the peripheral.
e.

Set the ON/OFF switch on the peripheral to the ON ( | )
position.

2. If you are connecting a peripheral using DEC423 cables:
a. Set the ON/OFF switch to the OFF (O) position.
b. Connect the 25-pin D-sub connector of the peripheral cable to
the asynchronous modem control port.
c.

Tighten the screws on each side of the adapter using a small
screwdriver.

d. Connect the EIA-232 to DEC423 adapter to the asynchronous
cable.
e.

Connect the DEC423 cable to the the MMJ port on the adapter.

Connect the other end of the DEC423 cable to the correct port
on the peripheral.

g. Set the ON/OFF switch on the peripheral to the ON ( | )
position.

B–10 Connecting Peripheral Device Cables

The following EIA-232 cable is available: 2T-BC22F-10. The peripheral

Model 100 or 100A to a Rack-Mountable VAX 4000 Model 100A.
To upgrade a Rack-Mountable VAX 4000 Model 100 single DSSI to
a Rack-Mountable VAX 4000 Model 100A dual DSSI you need the
following kit:
•

2T-KFDDA-CF Single to Dual DSSI Upgrade Kit (see Figure C–1

Single to Dual DSSI Upgrade Procedure C–5

1. Unpack and inspect all upgrade kits, and report any missing or
damaged items to your local Digital sales representative.
2. Ensure the customer has backed up all data and shut down the
system.
3. If required, install Firmware Version 2.3 Upgrade Kit (P/N QZ004AA-FW) or a higher version per instructions included with the
kit.
4. If required, install VMS Upgrade Version 5.5.2H4 (P/N QZ-001AAUW) per instructions included with the kit.
5. Access the unit by extending the system outside the cabinet as
described in Section 4.1.
6. Remove the enclosure cover as described in Section 4.3.
7. Refer to Figure C–3. Remove the upper and lower drive mounting
shelves together as a single unit (it is not necessary to disassemble
the shelves themselves). Unscrew all six screws from the shelves;
leave
the captive screws
in position and save the Phillips screws

for reinstallation
of
the
shelves.
Remove the internal power

cables .

9. Disconnect the internal SCSI cable from the backplane (see
Figure C–5):
•

Release the memory module nearest the internal SCSI connector
by pressing the tabs on each end, and tip it backward .

12. Remove the single DSSI
card
by gently prying
it loose from the

backplane connector . Use a standoff tool
to compress the
 post
so that the corner of the card can be lifted off of the standoff . Lift
the card out and place it on an antistatic mat.

13. Refer to Figure C–7. Install the dual DSSI card
onto the

backplane connector . Align the new card on the standoffs
so
that it is positioned above the backplane connector, then gently seat
it onto the connector and the standoffs.

14. Connect the new external DSSI bus cable into the DSSI connector
that is closest to the front of the system (see Figure C–7).

15. Reconnect the internal DSSI bus cable
into the DSSI connector
that is closest to the rear of the system (see Figure C–7).
16. Replace the shelves by reversing step 11d.
17. Connect the internal SCSI connector by reversing step 11c.
18. Connect the internal DSSI connectors from all drives mounted on
the shelves.
19. Connect the dc power cables by reversing step 11a.
20. Reinstall the enclosure cover by reversing the procedure in
Section 4.3.
21. If necessary, install the caution label (P/N 36-24385-01) on the
center of new top cover bustle so that it can be read when facing the
rear of the unit.
