Environmental Maximum shock Operating Storage Altitude Operating One shock pulse in the positive z axis (one pulse on each side of the system) of 31 G for 2.6 m in the operational orientation. Six consecutively executed shock pulses in the positive and negative x, y, and z axes (one pulse on each side of the system) of 71 G for up to 2 m. -30.5 m to 3048 m (-50 to 10,000 ft). NOTE: For altitudes above 2950 ft, the maximum operating temperature is derated 1.8 ºF/1000 ft. Storage Up to 12,000 m ( 39,370 ft). Operating Altitude De-rating Up to 35 °C (95 °F) maximum temperature is reduced by 1 °C/300 m (1 °F/547 ft) 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/319 ft) 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/228 ft) above 950 m (3,117 ft) Particulate Contamination NOTE: This section defines the limits to help avoid IT equipment damage and/or failure from particulates and gaseous contamination. If it is determined that levels of particulates or gaseous pollution are beyond the limits specified below and are the reason for the damage and/or failures to your equipment it may be necessary for you to remediate the environmental conditions that are causing the damage and/or failures. Remediation of environmental conditions will be the responsibility of the customer. Air Filtration NOTE: Applies to data center environments only. Air filtration requirements do not apply to IT equipment designed to be used outside a data center, in environments such as an office or factory floor. Data center air filtration as defined by ISO Class 8 per ISO 14644-1 with a 95% upper confidence limit. NOTE: Air entering the data center must have MERV11 or MERV13 filtration. Conductive Dust NOTE: Applies to data center and non-data center environments. Air must be free of conductive dust, zinc whiskers, or other conductive particles. Corrosive Dust • Air must be free of corrosive dust. • Residual dust present in the air must have a deliquescent point less than 60% relative humidity. 9
