7.4.4.2 Vibration a. Operating-normal The drive as installed for normal operation, shall comply with the complete specified performance while subjected to continuous vibration not exceeding 5 - 500 Hz, swept sine: 0.5 G (zero to peak) 10 - 500 Hz, random: 0.00051 G2/Hz Vibration may be applied in the X, Y, or Z axis. b. Operating-abnormal Equipment as installed for normal operation shall not incur physical damage while subjected to periodic vibration not exceeding: 15 minutes of duration at major resonant frequency 5 - 500 Hz, swept sine: 0.75 G (zero to peak) 10 - 500 Hz, random: 0.0029 G2/Hz Vibration occurring at these levels may degrade operational performance during the abnormal vibration period. Specified operational performance will continue when normal operating vibration levels are resumed. This assumes system recovery routines are available. c. Non-operating The limits of non-operating vibration shall apply to all conditions of handling and transportation. This includes both isolated drives and integrated drives. The drive shall not incur physical damage or degraded performance as a result of continuous vibration not exceeding: 5 - 22 Hz, swept sine: 0.25 G, (zero to peak) 22 - 350 Hz, swept sine: 5.0 G (zero to peak) 350 - 500 Hz, swept sine: 1.0 G (zero to peak) 10 - 500 Hz, random: 0.0118 G2/Hz Vibration may be applied in the X, Y, or Z axis. 7.4.5 Air cleanliness The drive is designed to operate in a typical office environment with minimal environmental control. 7.4.6 Corrosive environment Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every potential application environment. Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives. 32 Savvio 15K.2 SAS Product Manual, Rev. G
