10.1 Mean Time Between Failure
The following is the calculated Mean Time Between Failures (MTBF) at maximum configuration
at 35°C (ambient air). These values are derived using a historical failure rate and multiplied by
factors for application, electrical and/or thermal stress and for device maturity. MTBF estimates
should be viewed as “reference numbers” only.
• Calculation Model: Telcordia Issue 1, method I case 3
• Operating Temperature: Server in 35 °C ambient air
• Operating Environment: Ground Benign, Controlled
• Duty Cycle: 100%
• Quality Level: II
