B 31 6. 4 Environmental limits Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58. 7°F (14. 8°C). Maximum wet bulb temperature is 82°F (28°C). Operating The maximum allowable continuous or sustained HDA case temperature for the rated Annualized Failure Rate (AFR) is 122°F (50°C) The maximum allowable HDA case temperature is 60°C. Occasional excursions of HDA case temperatures above 122°F (50°C) or below 41°F (5°C) may occur without impact to the specified AFR. Continual or sustained operation at HDA case temperatures outside these limits may degrade AFR. Provided the HDA case temperatures limits are met, the drive meets all specifications over a 41°F to 131°F (5°C to 55°C) drive ambient temperature range with a maximum temperature gradient of 86°F (30°C) per hour. Air flow may be needed in the drive enclosure to keep within this range (see Section 8. 3). Operation at HDA case temperatures outside this range may adversely affect the drives ability to meet specifications. To confirm that the required cooling for the electronics and HDA case is provided, place the drive in its final mechanical configuration, perform random write/read operations and measure the HDA case temperature after it has stabilized. Non-operating ­40° to 158°F (­40° to 70°C) package ambient with a maximum gradient of 86°F (30°C) per hour. This specification assumes that the drive is packaged in the shipping container designed by Seagate for use with drive. HDA Temp. Check Point 1. 0 " . 5" Figure 7. Locations of the HDA temperature check point 6. 4. 2 Relative humidity The values below assume that no condensation on the drive occurs. Operating 5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour. Non-operating 5% to 95% non-condensing relative humidity. 32 Cheetah NS 10K. 2 FC Product Manual, Rev.

Non-operating ­1, 000 to +40, 000 feet (­305 to +12, 192 meters) 6. 4. 4 Shock and vibration Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is installed in an enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur internally to the enclosure resulting in drive movement in excess of the stated limits. If this situation is apparent, it may be necessary to modify the enclosure to minimize drive movement. The limits of shock and vibration defined within this document are specified with the drive mounted by any of the four methods shown in Figure 8, and in accordance with the restrictions of Section 8. 4.
