Rackmount Installation for
the IEC RS–310 Cabinet
Installation Procedure
(IEC RS–310 Cabinet)
Overview

This chapter describes how to install a DEC 3000 Model 500
(PE50A–B9) or Model 500S (PE50A–D9) AXP rackmount system
in an IEC RS–310 (RETMA) cabinet.
NOTE
The configurations that this procedure supports do not
require a power controller.

Cabinet
Location

The customer chooses the location to install the cabinet. When
the location is identified, perform the following steps:
Steps

Action

Move the cabinet to the selected location.

Use an open end (spanner) wrench to screw down the
cabinet leveler feet.

Place a spirit level on the cabinet base to ensure that
the cabinet is level.

Readjust the leveler feet, if necessary, until the cabinet
is level.

Slide out the stabilizer bar to support the weight of the
system being installed.

Installation Procedure
(IEC RS–310 Cabinet), Continued
Determine the
Installation
Area in the
Cabinet

To determine the installation area for the PE50A–B9/D9 unit in
an IEC RS-310 cabinet, perform the following steps at the front
and rear cabinet rails. See Figure 1–1.
WARNING
Digital does not recommend installing the system in
the top area of the cabinet, for stability reasons.
The space between mounting holes in the cabinet rails follows a
pattern of 0.50 inches (1.27 cm), 0.625 inches (1.59 cm), and 0.625
inches (1.59 cm). This pattern is repeated for the length of the
rails.
Steps

Action

Select a section of the cabinet rail where there is a 0.50
inch (1.27 cm) space between two holes.

Make a mark between the holes. This is your starting
point.

Count up or down three holes. This is one set and
equals 1.75 inches (4.45 cm).

Count up or down nine sets and make a mark. The area
between the marks is the installation area.

The total installation area is 15.75 inches (40.01 cm). The
equation for calculating the total area is
1.75 inches (4.45 cm) 2 9 sets = 15.75 inches (40.01 cm)
NOTE
The hole count described in this section will install
the system in any predetermined 15.75-inch (40.01 cm)
area.

Chapter 2
Rackmount Installation
for the H9A00–AJ Cabinet
Installation Procedure
(H9A00-AJ Cabinet)
Overview

This chapter describes how to install the DEC 3000 Model 500
(PE50A–B9) or Model 500S (PE50A–D9) AXP rackmount system
in an H9A00-AJ cabinet.
NOTE
The configurations that this procedure supports do not
require a power controller.

Cabinet
Location

The customer chooses the location to install the cabinet. When
the location is identified, perform the following steps:
Steps

Action

Move the cabinet to the selected location.

Use an open end (spanner) wrench to screw down the
cabinet leveler feet.

Place a spirit level on the cabinet base to ensure that
the cabinet is level.

Readjust the leveler feet (if necessary) until the cabinet
is level.

Slide out the stabilizer bar to support the weight of the
system being installed.

Installation Procedure
(H9A00-AJ Cabinet), Continued
Determine the
Installation
Area in the
Cabinet

To determine the installation area for the PE50A–B9/D9 unit in
an H9A00–AJ cabinet, perform the following steps at the front
and rear cabinet rails. See Figure 2–1.
WARNING
Digital does not recommend installing the system in
the top area of the cabinet, for stability reasons.
The space between mounting holes in the cabinet rails follows a
pattern of 0.50 inches (1.27 cm), 0.625 inches (1.59 cm), and 0.625
inches (1.59 cm). This pattern is repeated for the length of the
rails.
Steps

Action

Select a section of the cabinet rail where there is a 0.50
inch (1.27 cm) space between two holes.

Make a mark between the holes. This is your starting
point.

Count up or down three holes. This is one set and
equals 1.75 inches (4.45 cm).

Count up or down 10 sets and make a mark. The area
between the marks is the installation area.

The total installation area is 17.50 inches (44.45 cm). The
equation for calculating the total area is
1.75 inches (4.45 cm) 2 10 sets = 17.50 inches (44.45 cm)
NOTE
The hole count described in this section will install
the system in any predetermined 17.50-inch (44.45 cm)
area.
