Particulate contamination
Specifications
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.
NOTE:
PowerEdge XR2 offers an optional kit to meet the dust and sand requirements per MIL-STD-810G, Method 510.5,
Procedure I.
