Setup Guide

Environmental
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
NOTE: Applies to data center and non-data
center environments.
• Air must be free of corrosive dust.
• Residual dust present in the air must have a deliquescent point less
than 60% relative humidity.
Gaseous Contamination
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity
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.
