the risk of hardware corrosion and degradation. In general, the humidity fluctuations within the data center should be minimized. It is also
recommended that the data center be positively pressured and have air curtains on entry ways to prevent outside air contaminants and
humidity from entering the facility.
For facilities below 40% relative humidity (RH), Dell EMC recommends using grounding straps when contacting the equipment to avoid
the risk of electrostatic discharge (ESD), which can harm electronic equipment.
NOTE:
As part of an ongoing monitoring process for the corrosiveness of the environment, Dell EMC recommends
placing copper and silver coupons (per ISA 71.04-1985, Section 6.1 Reactivity) in airstreams representative of those in
the data center. The monthly reactivity rate of the coupons should be less than 300 Angstroms. When monitored
reactivity rate is exceeded, the coupon should be analyzed for material species and a corrective mitigation process put
in place.
Shock and vibration
The following table provides the platform shock and vibration maximums and the transportation shock and vibration levels (in the vertical
direction).
NOTE:
Levels shown apply to all three axes, and should be measured with an accelerometer in the equipment enclosures
within the cabinet.

Hardware acclimation times
Units must acclimate to the operating environment before applying power. This requires the unpackaged system or component to reside in
the operating environment for up to 16 hours in order to thermally stabilize and prevent condensation.
