Maximum shock specificationsMaximum shock SpecificationsOperating Six consecutively executed shock pulses in the positiveand negative x, y, and z axes of 40 G for up to 2.3 ms.Storage Six consecutively executed shock pulses in the positiveand negative x, y, and z axes (one pulse on each side ofthe system) of 71 G for up to 2 ms.Table 30. Maximum altitude specificationsMaximum altitude SpecificationsOperating 3048 m (10,000 ft)Storage 12,000 m (39,370 ft)Table 31. Operating temperature de-rating specificationsOperating temperature de-rating SpecificationsUp to 35°C (95°F) Maximum temperature is reduced by 1°C/300 m (1°F/547ft) above 950 m (3,117 ft).35°C to 40°C (95°F to 104°F) Maximum temperature is reduced by 1°C/175 m (1°F/319ft) above 950 m (3,117 ft).40°C to 45°C (104°F to 113°F) Maximum temperature is reduced by 1°C/125 m (1°F/228ft) above 950 m (3,117 ft).Particulate and gaseous contamination specificationsThe following table defines the limitations that help avoid any equipment damage or failure fromparticulates and gaseous contamination. If the levels of particulates or gaseous pollution exceed thespecified limitations and result in equipment damage or failure, you may need to rectify theenvironmental conditions. Re-mediation of environmental conditions is the responsibility of thecustomer.Table 32. Particulate contamination specificationsParticulate contamination SpecificationsAir filtration Data center air filtration as defined by ISO Class 8 per ISO14644-1 with a 95% upper confidence limit.NOTE: This condition applies to data centerenvironments only. Air filtration requirements do notapply to IT equipment designed to be used outside adata center, in environments such as an office orfactory floor.NOTE: Air entering the data center must haveMERV11 or MERV13 filtration.Conductive dust Air must be free of conductive dust, zinc whiskers, orother conductive particles.41
