Installation Guidelines
General:
This section provides general information needed to install the DP027010. The general guidelines
provided include information pertinent to grounding, mounting, and minimum clearances.
This computer system contains static sensitive devices. Proper static device handling procedures must be
followed.
There are no user-serviceable parts in this computer system. Opening or disassembly of the computer
enclosure by persons not certified by CDI will void the warranty.
Installation Sequence Overview:
- Remove computer from shipping carton, retain carton if desired.
- Remove protective plastic from computer
- Remove and store the Windows installation CD and installation key.
- Perform a visual inspection for damage.
- Install bracket, ensure required clearances are maintained
- Install chassis ground strap
- Install power and Ethernet cables
Adequate airflow around the exterior of the unit is important to the interior temperature of the unit. Fans
are used to create airflow through the military computer ensuring that a correct working temperature is
maintained. One of the fans is located on top of the CPU chip and is used to cool the processor. Another
fan is built into the power supply housing and blows air out of the unit. Another fan is located on the rear
chassis cover and blows air out of the cabinet.
Grounding:
This computer system is equipped with a three-wire power cable. When connected to an appropriate AC
power receptacle, this cable grounds the computer chassis. (Signal grounds are isolated from chassis
ground). The AC line plug shall be inserted only in a receptacle provided with a protective earth contact. A
ground stud is provided for optimum grounding, and is required for shipboard installation. Use 12 AWG
stranded wire or larger, a grounding strap (or braid) is highly recommended. The computer chassis
ground stud is ¼ inch diameter, use an appropr ia te siz e term inal lug and lockwasher.
Bulkhead Mounting:
This computer system is designed for bulkhead mounting by way of a bracket provided for use with this
computer. Mounting brackets are available in two styles: Pivot and non-pivot. Although each bracket has
the same mounting bolt pattern, the Pivot style bracket requires greater clearance in the front. Refer to
Figures 1 through 5 for mounting bolt patterns and sizes for each bracket. During installation the bracket
is mounted first, then the computer is mounted to the bracket. The bracket is designed to mount with four
3/8”x16 SAE grade 8 bolts, including washer and lock washer. The bolts are tightened to 35 ft/lbs. The
bracket should be mounted flat and level. See Figure 3 for mounting of computer system to the
appropriate bracket.
Once the bracket is mounted, the computer is mounted to the bracket. Use the four provided allen
screws, and combine with a washer and lock washer (not included). Two people are required to mount

MPAC-18 Manual
the computer, the computer is held level while the allen screws are installed through the bracket. Tighten
the allen screws to 20-25 ft/lbs.
Clearances:
Airflow: Inlets and outlets must have at least 1 inch (25mm) around them and not be obstructed for
adequate airflow to maintain the correct working temperature. In a military environment, the panel into
which the unit is mounted should provide protection from dust.
Cabling: All input/output (I/O) connections are via bottom access. At least 8 inches (20cm) of
unobstructed space is required at the bottom of the computer for unrestricted cable connection. See
figures 9 and 10 for bottom connector panel layout.
Brackets: See figures 3 and 4 for proper clearances for each bracket assembly. An access area of
approximately 4 inches (10 cm) to the sides is required in the area of the allen screws that mount the
computer to the bracket.

Diagnostics and Troubleshooting
This section consists of “Self-Test Diagnostics,” “Troubleshooting,” and “Corrective Actions.” “Self-Test
Diagnostics,” describes how to respond to errors that could be detected by the automatic self-test that is
performed each time the DP027010 military computer powers up. “Troubleshooting” contains tables of
symptoms, their possible causes, and recommended corrective actions. “Corrective Actions” contains
detailed procedures that are too lengthy to include in the Troubleshooting tables.
Self-Test Diagnostics
The computer automatically performs self-test diagnostics each time it is powered up. The self-test
consists of a series of checks that verify correct performance of the computer hardware. When the selftest is being performed, you will see the message XXXX KB OK displayed on the screen, where XXXX is
a number that increases until it matches the amount of usable memory.
System Test and Initialization
These routines test and initialize board hardware. If the routines encounter an error during the tests, you
will see an error message on the screen. There are two kinds of errors: fatal and non-fatal. If a non-fatal
error occurs, the system can usually continue the boot up sequence. Non-fatal error messages usually
appear on the screen with the following instruction:
press <F1> to RESUME
Write down the message and press the F1 key to continue the boot-up sequence.
System Configuration Verification
These routines check the current system configuration against the values stored in the CMOS memory. If
they don’t match, the program will generate an error message. To correct this condition, you will need to
run the BIOS setup program and correct the configuration information in memory.
There are three situations in which you might need to change the CMOS settings:
. You are starting your system for the first time.
1
2
. You have changed the hardware attached to your system.
. The CMOS memory had lost power and the configuration information has been erased.

Figure 7. Pin configuration
The SBC-PIII provides an industry standard RJ-45 connector for 10 Mb/s and 100 Mb/s operation. It
supports N-way auto-negotiation, full duplex flow control in compliance with IEEE 802.3x. It uses PCI
bus master data transfers with programmable PCI burst size. Includes 16K boot ROM, interface to 9346
(64 x 16-bit EEPROM) for storage of resource configuration and ID parameters and large independent Rx
and Tx FIFOs.
Three levels of power down modes: sleep, power-down with internal clock running, and power-down with
internal clock halted. Digital and Analog loopback capability. Unshielded twisted pair (UTP) cables
connect the SBC-PIII to other computers, hubs and bulkhead connectors. SBC-PIII supports most
popular Ethernet networks. The Ethernet Controller option used on SBC-PIII is a “Plug and Play” device
and resources can be set by program control. The exact resource utilization varies with system
configuration. The Ethernet controller will “seek” available resources. In addition, the Ethernet Controller
can be disabled through user settings in the BIOS Setup and in the Windows™ Control Panel | System |
Device Manager.
The Advanced Power Management feature minimizes power usage in Normal operation, Standby (Sleep)
modes and Panel-Off Power-Saving Mode. Offers Flexible On-chip Activity Timer facilitating ordered
shutdown of the display system. VESA Standards supported in Panel-Off Power-Saving Mode.
VIDEO INTERFACE
The SBC-PIII design is a highly integrated design Flat Panel and CRT GUI Accelerator, with Multimedia
Engine, Palette/DAC, and Clock Synthesizer. Includes hardware Acceleration, optimized for Windows™
BitBLT format, 64-bit Graphics Engine, System-to-Screen and Screen-to-Screen BitBLT. Video
Acceleration with source and destination Transparent BLT, instant Full Screen Page Flip and read back of
CRT Scan line counters. Advanced Power Management feature minimizes power usage with VESA
Standards supported.
