– Under no circumstance, can any combination of the worst case workload and configuration result
in system shutdown or design exposure at 40°C
– The worst case workload (such as linpack and turbo-on) may have performance degradation
• Airborne particulates and reactive gases acting alone or in combination with other environmental
factors such as humidity or temperature might pose a risk to the water-cooled technology tray. For
information about the limits for particulates and gases, see “Particulate contamination” on page 851.
