NOTE
If Intel
®
Xeon
®
Scalable processors (Platinum 8180, 8180M, 8168 or
Gold 6144, 6146, 6154) are used, the maximum operating temperature
supported is 35°C (95°F).
Relative humidity (RH,
non-condensing)
l Operating humidity: 5% to 85%
l Storage humidity: 5% to 95%
l Long-term storage humidity: 30% to 69%
l Maximum change rate: 20%/h
Altitude
l Operating altitude ≤ 3050 m (10006.44 ft)
– When the server configuration complies with ASHRAE
Class A2 standards and the altitude is above 900 m
(2952.76 ft), the highest operating temperature
decreases by 1°C (1.8°F) for every increase of 300 m
(984.24 ft).
– When the server configuration complies with ASHRAE
Class A3 standards and the altitude is above 900 m
(2952.76 ft), the highest operating temperature
decreases by 1°C (1.8°F) for every increase of 175 m
(574.14 ft).
l HDDs cannot be used at an altitude of over 3000 m (9842.4
ft).
Corrosive gaseous
contaminant
Maximum corrosion product thickness growth rate:
l Copper corrosion rate test: 300 Å/month (meeting level G1
requirements of the ANSI/ISA-71.04-2013 standard on
gaseous corrosion)
l Silver corrosion rate test: 200 Å/month
