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

##

B.2 Reliability

Reliability prediction was done using Telcordia document SR-332, Issue 1. The prediction assumed 25˚ Celsius operating temperature with 100 percent duty cycle, in a ground-benign, controlled environment.

- MTBF: 630,000 hours

- One year limited warranty

##

B.3 Mechanical

This section includes the mechanical specifications for dimensions and weight. The AMC.1-HDD SAS disk meets the PICMG 3.0 AdvancedTCA Specification R2.0 ECN002 and AMC.0 R2.0 for all mechanical parameters.

### B.3.1 Board Dimensions and Weight

The AMC.1-HDD SAS disk is 181.5 mm by 73.5mm and conforms to the component height requirements of a mid-size module and can be configured as a full-size module. PCI Express x4 connections are made through the AMC edge fingers.

The AMC.1-HDD SAS disk conforms to the PICMG AMC.0 single-width, mid-height AMC Form Factor for all mechanical parameters. Mechanical dimensions are shown in the illustration and are outlined in the following table.
