External Connectors

External Connectors are customized per request

CMC-e Construction

The CMC-e is designed and constructed in accordance with the general requirements of MIL-STD-454.

Thermal Design

The cooling of the components on the CMC-e cards is accomplished by conduction. The cooling of the CMC-e Power Supply and the Pentium chip are accomplished by by conduction through the aluminum enclosure of the unit which is built as an heat-sink.

External Connectors

External connectors are used for interfacing with the subassemblies or equipment and are in accordance with requirement of MIL-STD-454. Connector mating bodies are keyed, and keyed locations are varied to prevent improper installation.

Identification and Marking

The marking and labels of the equipment meet the requirements of MIL-M-13231.

Moisture & Fungus Resistance

CMC-e assemblies are moisture resistant and are not nutrients for fungi. The PC Cards are treated with Conformal coating for protection. The coating conforms to MIL-I-46058C.

External Finishes

The computer external surfaces are chemically treated prior to painting. All residues and contaminants are removed prior to applying one coat of primer. The finish is semi-gloss per FED-STD-595.

Processes and Treatment

Processes and treatments (welding, soldering, brazing and corrosion (resistance protection) of the enclosure is in accordance with MIL-STD-454.

Environmental Conditions

Temperature

The CMC-e will not be damaged or affected by the effects of ambient air temperature as follows:

Operating

The CMC-e shall meet performance requirements specified herein after exposure to temperatures:

Standard temperature range 0° to 55°C .

Extended temperature -20° to 65°C (with flash disk).

Non-operating

(Storage and transportation) -40° to 85°C.

Sand and Dust

The CMC-e shall operate as specified herein while and after being subjected to sand and dust as encountered in dry arid arias. The CMC-e shall meet the requirements specified in MIL-STD-810F.

Salt Fog

The CMC-e is resistant to the corrosive effects of salt fog environment. The CMC-e meets the requirements specified in MIL-STD-810E Method 509.3 Procedure I. The base metal shall not be visible through the finish or coating, nor shall be any evidence of blistering, softening, separation from the base metal, corrosion products, or other coating failure.

Relative humidity

Up to 95% relative humidity, non-condensing,per MIL-STD-810F

Salt Fog

5% solution per MIL-STD-810F method 509.3

Vibrations

MIL-STD-810F Method 514.5 Procedure I

Shock

Altitude

- With standard hard disks up to 15,000ft (or the equivalent atmospheric pressure),

operating and non-operating

- With Flash disks up to 40,000ft (or the

equivalent atmospheric pressure), operating

and non-operating

Electromagnetic Interference

The CMC-e as specified with its internal boards, and the computer’s components, disks and power supplies complies the requirements of MIL-STD-461E as follows:

CE102

Conducted emissions, power leads, 10 kHz to 10 MHz.

RE102

Radiated emissions, electric field, 100 kHz to 1.0 GHz.

RS103

Radiated susceptibility, electric field, 2 MHz to 2.0 GHz.

CS114

Conducted susceptibility, DC cable injection, 10 kHz to 400MHz.

Maintainability

Interchangeability

The components of the CMC-e are physically and functionally interchangeable in accordance with MIL-STD-454. Parts or components of the same part number procured to this specification are physically and functionally interchangeable without selection, adjustment or fit.

Maintainability and Modularization

The CMC-e is designed such that it is completely maintainable by replacement of assemblies.

Maximum use is made of plug in module assemblies.

Reliability

The CMC-e -PC has an MTBF of 10,000 hours at 25°C . Mean Time To Repair (MTTR) does not exceed 30 minutes. The MTTR includes the time required to detect and isolate the failure, replace the failed unit, checkout the repair and return the system to full operational status.
