Drive Specifications
2.11 Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in
performance when subjected to the radio frequency (RF) environments defined in
performance when subjected to the radio frequency (RF) environments defined in
2.12 AFR and Warranty
The product will achieve an Annualized Failure Rate (AFR) of <1% when operated in an environment of ambient air
temperatures of 25°C. Operation at temperatures outside the specifications shown in
temperatures of 25°C. Operation at temperatures outside the specifications shown in
individual units.
AFR specifications are based on the following assumptions for consumer electronics environments:
• 8760 power-on-hours per year
• 10,000 average motor start/stop cycles per year
• Operations at nominal voltages
• Temperatures outside the specifications in
reliability.
• Normal I/O duty cycle for consumer electronics environments. Operation at excessive I/O duty cycle may
degrade product reliability.
The consumer electronics environment of power-on-hours, temperature, and I/O duty cycle affect the product
AFR.The AFR will be degraded if used in an enterprise application.
