MaximumshockSpecificationsOperating One shock pulse in the positive z axis of 31 G for 2.6 ms in all operational orientations.Storage Six consecutively executed shock pulses in the positive and negative x, y, and z axes (one pulse on eachside of the system) of 71 G for up to 2 ms.MaximumaltitudeSpecificationsOperating 3,048 m (10,000 ft)Storage 12,000 m (39,370 ft).Operatingtemperaturede-ratingSpecificationsUp 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).The following section defines the limits to help avoid IT equipment damage and/or failure from particulates and gaseouscontamination. If the levels of particulates or gaseous pollution are beyond the specified limits and cause equipment damage orfailure, you may need to rectify the environmental conditions. Remediation of environmental conditions is the responsibility ofthe customer.ParticulatecontaminationSpecificationsAir filtration Data center air filtration as defined by ISO Class 8 per ISO 14644-1 with a 95% upper confidence limit.NOTE: Applies to data center environments only. Air filtration requirements do not apply to ITequipment designed to be used outside a data center, in environments such as an office or factoryfloor.NOTE: Air entering the data center must have MERV11 or MERV13 filtration.Conductive dust Air must be free of conductive dust, zinc whiskers, or other conductive particles.NOTE: Applies to data center and non-data center environments.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.NOTE: Applies to data center and non-data center environments.GaseouscontaminationSpecificationsCopper couponcorrosion rate<300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.Silver couponcorrosion rate<200 Å/month as defined by AHSRAE TC9.9.NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.88 Technical specifications—PowerEdge FX2/FX2s
