Operating 8% to 80% relative humidity with a maximum gradient of 10% per hour. Non-Operating 5% to 95% relative humidity. 7. 4. 3 Effective altitude (Sea level reference) a. Operating -1000 to +10, 000 feet (-305 to +3048 metres) b. Non-Operating -1000 to +40, 000 feet (-305 to +12, 210 metres) 7. 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, resonance's 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 7. 4. 4-1. Operating The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding 10 g's at a maximum duration of 11 ms (half sinewave). Shock may be applied in the X, Y, or Z axis. Nonoperating The limits of nonoperating shock shall apply to all conditions of handling and transportation. This includes both isolated drives and integrated drives. The drive subjected to nonrepetitive shock not exceeding 60 g's at a maximum duration of 11 ms (half sinewave) shall not exhibit device damage or performance degradation. Shock may be applied in the X, Y, or Z axis. Packaged The drive as packaged in a single or multiple drive pack of gross weight 20 pounds (8. 95 kg) or less by Seagate for general freight shipment shall withstand drop test from 42 inches (1070 mm) against a concrete floor or equivalent. For additional details refer to specification 30190-001 (under 100 lbs. ) or 30191-001 (over 100 lbs. ) Package Size 3 3 600­1800 in (9, 832-29, 502 cm ) 3 >1800 in (>29, 502 cm ) Drop Height 48 in (121 cm) 42 in (106 cm) Product Manual - Hawk 2 Family (Wide bus) SCSI-2 (Volume 1), Rev.
