Item Specications
Relative
humidity (RH,
non-
condensing)
● Operating humidity: 8% to 90%
● Storage humidity (within three months): 8% to 85%
● Storage humidity (within six months): 8% to 80%
● Storage humidity (within one year): 20% to 75%
● Maximum change rate: 20%/h
Maximum
altitude
● For altitudes above 900 m (2952.72 ft), the highest
operating temperature decreases by 1°C (1.8°F) for every
increase of 300 m (984.24 ft) in altitude.
● At an altitude of over 3000 m (9842.4 ft), only Titanium
PSUs can be used.
● HDDs cannot be used at an altitude of over 3000 m
(9842.4 ft).
Acoustic noise The data listed in the following is the declared A-weighted
sound power levels (LWAd) and declared average bystander
position A-weighted sound pressure levels (LpAm) when the
server is operating in a 23°C (73.4°F) ambient environment.
Noise emissions are measured in accordance with ISO 7779
(ECMA 74) and declared in accordance with ISO 9296 (ECMA
109).
● Idle:
– LWAd: 5.1 Bels
– LpAm: 35.1 dBA
● Operating:
– LWAd: 6.1 Bels
– LpAm: 45.1 dBA
NOTE
The actual sound levels generated during server operating vary
depending on the server
conguration, load, and ambient
temperature.
Corrosive
gaseous
contaminant
Maximum corrosion product thickness growth rate:
● Copper corrosion rate test: 300 Å/month (meeting level
G1 requirements of the ANSI/ISA-71.04-2013 standard on
gaseous corrosion)
● Silver corrosion rate test: 200 Å/month
Particle
contaminant
● The equipment room environment meets the
requirements of ISO 14664-1 Class 8.
● There is no explosive, conductive, magnetic, or corrosive
dust in the equipment room.
NOTE
It is recommended that the particulate pollution in the equipment
room be monitored by a professional agency.
