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 appropriate size terminal 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

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 self-  
test 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:  
1. You are starting your system for the first time.  
2. You have changed the hardware attached to your system.  
3. The CMOS memory had lost power and the configuration information has been erased.
