Environment Specifications

A P P E N D I X A

This appendix describes the electrical, environmental, and mechanical specifications. It includes connector descriptions and pin outs, as well as illustrations of the board dimensions and connector locations.

This appendix contains the following topics:

Section A.1, Electrical and Environmental

Section A.2, Reliability

Section A.3, Mechanical

A.1 Electrical and Environmental

The following sections provide tables and illustrations showing the electrical and environmental specifications.

A.1.1 Absolute Maximum Ratings

The following values are stress ratings only. Do not operate at these maximums. See Section A.1.2, Normal Operating Ranges for normal operating conditions.

TABLE A-1 Absolute Maximum Electrical and Temperature Ratings
Payload voltage, +12V	0 VDC to +13.2VDC
Management voltage, +3.3V	0 VDC to +5.5VDC
Storage temperature:	-40˚ to +85˚ Celsius
Noncondensing relative humidity:	<95% at 40˚ Celsius

A.1.2 Normal Operating Ranges

TABLE A-2 Normal Operating Electrical and Temperature Ratings
Description	Range
Nominal operating voltage	+10.8 to +13.2VDC Payload Power +2.97 to + 3.63VDC Management Power
Operating temperatures: 60m below sea level up to 1800m above sea level* from 1800m up to 4000m above sea level**	-5˚ to +55˚ Celsius -5˚ to +40˚ Celsius
Operating humidity	<85% at 40˚ Celsius
Idle power consumption (without links)	3.792W
Maximum power consumption	6.816W

^{*The MTBF will be significantly reduced if operated above 45˚ C for more than 96 consecutive hours.}^{**The MTBF will be significantly reduced if operated above 30˚ C for more than 96 consecutive hours.}

A.2 Reliability

Reliability prediction was done using Issue 1, Method I, Case 3 of the Telcordia Industrial Reliability program. The prediction assumed 25˚C operating temperature with 100% duty cycle, in a ground benign, controlled environment.

MTBF: 1,197,323 hours

2 year limited warranty

A.3 Mechanical

This section includes the mechanical specifications for dimensions and weight. The AMC.2-OP conforms to the PICMG AMC.0 single-width, full-height AMC form factor for all mechanical parameters.

A.3.1 Board Dimensions and Weight

The AMC.2-OP conforms to the PICMG AMC.0 single-width, full-height AMC form factor for all mechanical parameters. Mechanical dimensions are shown in the illustration and are outlined in the following table.

TABLE A-3 Board Dimensions and Weight
Item	Dimensions or Weight
PCB	181.5mm x 73.5mm x 1.6mm
Board	AMC.0 R2.0 single-width, full-height form factor
Weight	181.4g (0.4lb)
