(~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 (32.9°F) dew point, but not lower -10°C (14°F) dew point 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 (41°F/hr) for data centers employing tape drives and 20°C/hr (68°F/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 (68°F/hr) of temperature change from the
shipping environment to the operating environment.
• Condensation is acceptable, but not rain.
• When the ambient temperature is higher than 36°C (96.8°F), 135-watt and 145-watt microprocessors
might face performance degradation when operating a heavy workload.
• Your server supports the active graphics processing unit (GPU) only. To support the GPU, observe
the following system requirements:
Chassis GPU wattage
Ambient
temperature
CPU wattage Fan type
3.5-inch-drive
chassis Not exceed 240
watt Not exceed 35°C
(95°F) No special
requirement
Single-rotor
3.5-inch-drive
chassis
Above 240 watt
Not exceed 30°C
(86°F)
For 300-watt Intel
Phi GPU (supported
in 3.5-inch-drive
chassis only), the
CPU wattage must
not exceed 120
watt.
Single-rotor
3.5-inch-drive
chassis
Above 240 watt Above 30°C (86°F)
No special
requirement
Dual-rotor
2.5-inch-drive
chassis Not exceed 300
watt Not exceed 35°C
(95°F) No special
requirement
Single-rotor
The NVIDIA Quadro M6000 24GB GPU accelerator is supported only in eight 3.5-inch-drive or sixteen
2.5-inch-drive models. The ambient temperature must not exceed 27°C (80.6°F) and the redundant
fan function is not supported due to thermal limitation.
• To support IO accelerator adapters, observe the following requirements:
Chassis Ambient temperature Fan type
3.5-inch-drive chassis Not exceed 30°C (86°F) Single-rotor
3.5-inch-drive chassis
Above 30°C (86°F)
Dual-rotor
2.5-inch-drive chassis Not exceed 35°C (95°F) Single-rotor
