Particulate and gaseous contamination specifications
Table 18. Particulate contamination specifications
Particulate contamination Specifications
Air filtration Data center air filtration as defined by ISO
Class 8 per ISO 14644-1 with a 95% upper
confidence limit.
NOTE: This condition applies only to data center environments. 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.
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: This condition 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: This condition applies to data center and non-data center environments.
Table 19. Gaseous contamination specifications
Gaseous contamination Specifications
Copper coupon corrosion rate <300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
Silver coupon corrosion rate <200 Å/month as defined by AHSRAE TC9.9.
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
Standard operating temperature specifications
NOTE:
1 Not available: Indicates that the configuration is not offered by Dell EMC.
2 Not supported: Indicates that the configuration is not thermally supported.
NOTE: All components including the DIMMs, communication cards, M.2 SATA, and PERC cards can be supported with sufficient
thermal margin if the ambient temperature is equal to or below to the maximum continuous operating temperature listed in these
tables with the exception of the Mellanox DP LP card.
