Preface
Audience

This guide is for use by Digital services
personnel or by self-maintenance customers.
Installation begins when site preparation is
completed and the DECsystem 5900 has been
delivered on a skid to the computer room.
If necessary, refer to the DECsystem 5900 Site
Preparation Guide.

Required Tools

The tools required to unpack and install the
DECsystem 5900 are:
•
•
•
•

Scissors or knife for opening packages
Screwdrivers; variety of Phillips and flat
blades
Wrenches, 3/4-inch to remove hold-down
brackets and 9/16-inch to bring feet down
Allen wrench, 1/4-inch, to open
DECsystem 5900 doors.

1 Unpacking and Positioning the
System
Remove the plastic wrap, the corner pads,
and any cardboard packaging.
To position the system in the computer lab,
follow these steps.
1. Leave 7 ft clearance from the front of the
skid.
2. Insert the skid ramps into the holes in
the front of the skid with arrows on skid
lined up with arrows on ramp boards.
3. With a 9/16-inch wrench, loosen and
remove the hold-down brackets on the
system’s feet. See Figure 1.
Figure 1

MLO-007680

4. While the system is still on the skid,
loosen the 3/4-inch upper (lock) nut on
each foot by turning clockwise. Turn
the 9/16-inch bottom nut on each foot
counterclockwise to raise the feet for skid
clearance.
Warning: The system weighs between
400 and 860 lbs. For safety, two people
are needed to roll the system down the
ramp.
5. Roll the system down the ramp boards
to its position. Front two wheels are on
casters, the rear two are fixed.
6. Leave 36-inch clearance at the front of
the system and 22-inch clearance at the
rear of the system for service.
7. Raise the system up on its feet as
follows: Loosen the 3/4-inch lock nut
(counterclockwise) on each foot. Lower
each foot into position by turning
clockwise on the 9/16-inch nut on the
foot. Tighten each 3/4-inch lock nut
counterclockwise to lock the feet in place.

2 Assembling the System Skirts
Open the system skirt kit.
The skirts are installed after the system has
been set in place and raised off the wheels
by the leveling feet, as explained Section 1 in
steps 6 and 7. The skirt kit is in a separate
box from the accessory kit.
A separate skirt is installed on each side of
the system. Each is attached to the system
by 2 quarter-turn Phillips captive screws.

2.1 Front Skirt

The front skirt, shown in Figure 2, has three
pieces that have to be fitted together, then
attached to system.

Side piece, 744165301

2.2 Side Skirts

One side skirt is shown in Figure 2. The side
skirts each have two parts—a side piece and
an "ear" that you attach to the side piece
with three self-tapping Phillips screws. Then
attach the side skirt to the system frame.

2.3 Rear Skirt

The center piece of the rear skirt has a
rectangular opening through which run all
external power and signal cables. The rear
skirt parts are illustrated in Figure 3.
P/Ns 744165801 and 744165802 are the
curved pieces.
These curved pieces are attached to the
center piece with plastic push-in fasteners,
and attached to the frame with the pushin captive screws. The cable cover, P/N
74416600 (not shown in Figure 3), fits into
the notches on the two side pieces.

3 Connecting External Cables
External cables are connected from the rear
of the power controller and from the rear of
the CPU drawer. See Figure 4 and connect
the following.
Note: All external cables must run through
the opening in the center piece of the rear
skirt.

Power cable
Console cable
Ethernet cable
Internal power cables from power
controller to individual drawers, which
are connected at the factory.

Note: Most U.S. installations include the
power cord as part of the power controller.
Other countries are shipped unique,
detachable cords with the appropriate plug.

4 Powering Up the System
The power controller can be configured as
follows for a single point of power control at
the upper CPU drawer switch.

4.1 Power Controller

Th power controller is in the bottom level of
the DECsystem 5900. See Figure 5 and check
the following:
1

4

Power cable plugged in to the ac source.
Circuit Breaker switch up (On).
1/8 A fuse in place.
Remote/Local switch up (Remote).
If the Remote/Local switch is in the
Local mode (down), the drawers must be
powered up individually and manually.
Power controller sequence cable
connected.

Figure 6 shows the DECsystem 5900 front
with the door open. 3 is the CPU drawer.
Mass storage drawers are 4 , 5 , 1 , and 6 ,
in that order. Space 2 is reserved for CPU
upgrades.

4.2 Mass Storage Drawer Switches

Turn on the switches at the rear and front of
each mass storage drawer. Both must be on
to power up each drawer.

4.3 CPU Front Drawer Switches

Both switches on front of CPU drawer must
be on ( | ). See Figure 7.
1

Upper switch on ( | ); this is the main
system power switch, which powers the
whole system up/down when the Remote
/Local switch on the power controller is in
the Remote mode.
Lower switch on ( | ); this is for the CPU
drawer power on/off only.

5 Setting the Console Terminal
On the console, verify that the console
terminal communication set-ups are as
follows: 9600 baud rate, 8 bit, no parity, 1
stop bit.

6 Removing Blank Media
For protection during shipping, blank tape
and plastic protectors are installed in the
tape drives.
Put the dummy media and the plastic
protectors in the accessory box and save it
in case of re-shipment.
For proper loading and booting procedures,
see the Guide to Installing ULTRIX (AA–
PBLOD–TE).

7 Running Power-Up Self-Tests
The power up process takes about one minute
from the time the system is turned on.
Names of the tests are displayed on the
console as they are performed. The tests are
also displayed in hexidecimal values on the
pair of four LEDs at rear of the CPU drawer.

7.1 Two Non-Problem Messages

Error messages regarding the non-existent
keyboard and pointer will be displayed on the
console:
?STF (Ln#0 Kbd self test)
?STF (Ln#1 Pntr kbd self test)

As there is neither keyboard nor pointer
directly connected to the system, these
messages can be ignored.

7.2 Problems with Option Modules

The power-up self-tests do not test the devices
in the mass storage drawers. Device IDs
/addresses and function of the installed
devices can be verified while running
extended tests.
See the DECsystem 5900 Service Guide,
EK–D590A–PS, for extended testing of
mass storage devices and I/O options and
troubleshooting procedures.

8 Resolving Problems
See the DECsystem 5900 Service Guide.
