Operation of the drive at the maximum case temperature is intended for short time periods only. Continuous operation at the elevated temperatures will reduce product reliability. Table 2: Items in Figure 7 PCBA and HDA temperatures Maximum allowable case temperature (°C) operating Maximum allowable case [3] temperatures (°C) to meet MTBF spec. HDA [2] 1 2 3 4 Notes. [1] 60 64 70 78 63 45 49 55 63 48 [2] [3] Section 8. 4. 1 describes the air-flow patterns used when generating the 1 million hours MTBF guidelines in column 2. Air flow was opposite that shown in Section 8. 4. 1. Local air velocity was 0. 92 m/sec (180 lfpm). Inlet air temperature to the drive was 77°F (25°C), plus 9°F (5°C) temperature rise in the test enclosure (86°F/30°C ambient local to the drive). Measure HDA temp at point labeled "HDA" on Figure 7. PCB mounted integrated circuit case. b. Non-operating ­40° to 158°F (­40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification assumes that the drive is packaged in the shipping container designed by Seagate for use with drive. 24 Barracuda 18LP FC Product Manual, Rev. Check Point . 5" 4 1 2 3 Figure 7. Locations of PCBA components listed in Table 2 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 10% per hour. Non-operating 5% to 95% non-condensing relative humidity. 6. 4. 3 Effective altitude (sea level) a. Operating ­1, 000 to +10, 000 feet (­305 to +3, 048 meters) b. 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. Barracuda 18LP FC Product Manual, Rev. B 25 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. 5. Orientation of the side nearest the LED may be up or down. [. . . ] You can send questions or comments 24 hours daily and exchange messages with a technical support specialist from 8:00 A. M.
