Table 19: Random vibration PSD profile break points (operating) Hz 200 500 m x 10n (m2/sec4)/Hz 4.8 x E-2 4.8 x E-2 6.9.1.2 Swept sine vibration Swept sine vibration (zero to peak 5 to 500 to 5 Hz sine wave) 9.8 m/sec2 (1 G) (5-500 Hz) Sweep rate (oct/min) 1.0 6.9.2 Nonoperating vibration The disk drive withstands the following vibration levels without any loss or permanent damage. 6.9.2.1 Random vibration The test consists of a random vibration applied in each of three mutually perpendicular axes for a duration of 15 minutes per axis. The PSD levels for the test simulating the shipping and relocation environment is shown below. Table 20: Random Vibration PSD Profile Breaking points (nonoperating) Hz (m2/sec4)/Hz 2.5 0.096 5 2.88 40 1.73 500 1.73 Note: Overall RMS (root mean square) level of vibration is 29.50 m/sec2 (3.01G) 6.9.2.2 Swept sine vibration • 49 m/sec2 (5 G) (zero-to-peak), 5 to 500 to 10 Hz sine wave • 0.5 oct/min sweep rate • 25.4 mm (peak-to-peak) displacement, 5 to 10 to 5 Hz 6.9.3 Operating shock The drive meets the following criteria while operating in the conditions described below. The shock test consists of 10 shock inputs in each axis and direction for total of 60. There must be a delay between shock pulses long enough to allow the drive to complete all necessary error recovery procedures.
