– Processor E5-2699 v4, E5-2698 v4, E5-2697 v4, E5-2667 v4, E5-2643 v4, E5-2637 v4 may face
performance degradation when operating a heavy workload at 35°C to 40°C ambient temperature
in a 3.5-inch chassis.
• Chassis is powered on.
• A3 - Derate maximum allowable temperature 1°C/175 m above 950 m.
• The minimum humidity level for class A3 is the higher (more moisture) of the -12°C dew point and
the 8% relative humidity. These intersect at approximately 25°C. Below this intersection (~25°C) the
dew point (-12°C) represents the minimum moisture level, while above it relative humidity (8%)
is the minimum.
• Moisture levels lower than 0.5°C DP, but not lower -10 °C DP or 8% relative humidity, can be
accepted if appropriate control measures are implemented to limit the generation of static electricity
on personnel and equipment in the data center. All personnel and mobile furnishings and equipment
must be connected to ground via an appropriate static control system. The following items are
considered the minimum requirements:
– Conductive materials (conductive flooring, conductive footwear on all personnel that go into the
datacenter, all mobile furnishings and equipment will be made of conductive or static dissipative
materials).
– During maintenance on any hardware, a properly functioning wrist strap must be used by any
personnel who contacts IT equipment.
• 5°C/hr for data centers employing tape drives and 20°C/hr for data centers employing disk drives.
• Chassis is removed from original shipping container and is installed but not in use, for example,
during repair, maintenance, or upgrade.
• The equipment acclimation period is 1 hour per 20°C of temperature change from the shipping
environment to the operating environment.
• Condensation is acceptable, but not rain.
