Location of the HDA temperature check point 32 Cheetah 15K. 6 SAS Product Manual, Rev. A 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 ­1, 000 to +40, 000 feet (­305 to +12, 210 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 9, and in accordance with the restrictions of Section 8. 3. Operating--normal The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding 15 Gs at a maximum duration of 11 msec (half sinewave). The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding 25 Gs at a maximum duration of 2 msec (half sinewave). Operating--abnormal Equipment, as installed for normal operation, does not incur physical damage while subjected to intermittent shock not exceeding 40 Gs at a maximum duration of 11 msec (half sinewave). Shock occurring at abnormal levels may promote degraded operational performance during the abnormal shock period. Specified operational performance will continue when normal operating shock levels resume. Non-operating The limits of non-operating shock shall apply to all conditions of handling and transportation. The drive subjected to nonrepetitive shock not exceeding 80 Gs at a maximum duration of 11 msec (half sinewave) shall not exhibit device damage or performance degradation. The drive subjected to nonrepetitive shock not exceeding 300 Gs at a maximum duration of 2 msec (half sinewave) does not exhibit device damage or performance degradation. The drive subjected to nonrepetitive shock not exceeding 150 Gs at a maximum duration of 0. 5 msec (half sinewave) does not exhibit device damage or performance degradation. Shock may be applied in the X, Y, or Z axis. Cheetah 15K. 6 SAS Product Manual, Rev.

Operating--normal The drive as installed for normal operation, shall comply with the complete specified performance while subjected to continuous vibration not exceeding 10­500 Hz @ 0. 5 G (zero to peak) Vibration may be applied in the X, Y, or Z axis. 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 10­500 Hz @ 0. 75 G (X, Y, or Z axis) Vibration occurring at these levels may degrade operational performance during the abnormal vibration period.
