Summary of the environmental specifications of rack solution. Depending on the model, some features might not be available, or some specifications might not apply.
| Acoustic levels (idle/working mode) |
|---|
- Fan control from BMC with multiple temperature input
- Sound pressure level (LpAm): up to 82.9 dB
- Estimated that the rack will operate around 92dBA from rack rear, typical ambient and rack exercised
|
| Environment |
|---|
- Air temperature:
- Operating: ASHRAE Class A2 Compliance
- Temperature range: 10°C to 35°C (50°F to 95°F)
- Maximum rate of change: ≤ 20°C per hour
- Altitude de-rating: The maximum allowable operating temperature is de-rated by 1°C for every 300 m (1,000 ft) up to an altitude of 1,371 m (4,500 ft) above sea level.
- Non-Operating:
- Standard storage: -40°C to 70°C (Rack is shipped with pressurized nitrogen)
- With Di-H20: 5°C to 70°C (41°F to 158°F)
- With PG25: 10°C to 70°C (14°F to 158°F)
- Maximum altitude: 1,524 m (5,000 ft)
- Relative Humidity (non-condensing):
- Operating: 20% - 80%
- Humidity transition rate: < 10% per hour
- Particulate contamination
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 rack solution. For information about the limits for particulates and gases, see Particulate contamination.
The rack solution is designed for standard data center environment and recommended to be placed in industrial data center. |
