Ambient temperature management
Ambient temperature management
• Keep the ambient temperature to 40°C or lower to avoid performance degradation. If the ambient temperature is
over 40°C, performance degradation or throttled event might occur.
• Keep the ambient temperature to 30°C or lower to avoid performance degradation when choosing the rack mount
with the SE350 V2 1U2N Enclosure. It is advised that the ambient temperature should be kept under 27°C when AC
adapters are installed.
Environment
Environment
ThinkEdge SE350 V2 complies with ASHRAE Class A3 specifications. System performance may be impacted when
operating temperature is outside AHSARE A3 specification or fan failed condition outside A2 specification. ThinkEdge
SE350 V2 is supported in the following environment:
• Air temperature:
– Operating
– ASHRAE Class H1: 5°C to 25°C (41°F to 77°F); the maximum ambient temperature decreases by 1°C for every
500 m (1640 ft) increase in altitude above 900 m (2,953 ft).
– ASHRAE Class A2: 10°C to 35°C (50°F to 95°F); the maximum ambient temperature decreases by 1°C for
every 300 m (984 ft) increase in altitude above 900 m (2,953 ft).
– ASHRAE Class A3: 5°C to 40°C (41°F to 104°F); the maximum ambient temperature decreases by 1°C for
every 175 m (574 ft) increase in altitude above 900 m (2,953 ft).
– Server off: 5°C to 40°C (41°F to 104°F)
– Shipping/storage: -40°C to 65°C (-40°F to 149°F)
• Maximum altitude: 3,050 m (10,000 ft)
• Relative Humidity (non-condensing):
– Operating: 8% to 90%, maximum dew point : 24°C (75.2°F)
– Shipment/storage: 8% to 90%, maximum dew point : 27°C (80.6°F)
– Non-operating (unpacked) storage can pass the following condition: 5% to 95% at 38.7°C (101.7°F) maximum
dry-bulb temperature for 48 hrs.
• Particulate contamination
– Depending on the specific configuration,SE350 V2 supports a dust filter installed at the front of the enclosure.
The dust filter has a Minimum Efficiency Rating Value (MERV) of 5, per ASHRAE 52.2-2017 / 80% Average
Arrestance per ASHRAE 52.1-1992.
– SE350 V2 complies to IP3X Ingress Protection per ANSI/IEC60529-2020 Degrees of Protection Provided by
Enclosures (IP Code).
Attention: 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 server. For information about the limits for particulates and
gases, see "Particulate contamination" on page 12.
