Altitude
l
CH140 and CH140 V3 compute nodes
At an altitude of 900 m (2952.72 ft.), the highest operating
temperature is 35°C (95°F).
l
Other modules
At an altitude of 900 m (2952.72 ft.), the highest operating
temperature is 40°C (104°F).
If the device is used at an altitude between 900 m (2952.72 ft.)
and 5000 m (16404.00 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.
Noise
The data listed in the following represents the declared A-
weighted sound power levels (LWAd) and declared average
bystander position A-weighted sound pressure levels (LpAm)
when the server is operating at an ambient temperature of 23°C
(73.4°F). Noise emissions are measured in accordance with
ISO 7999 (ECMA 74) and declared in accordance with ISO
9296 (ECMA 109).
Idle:
l
LWAd: 7.2 Bels
l
LpAm: 53 dBA
NOTE
The actual sound levels generated during server operation vary
depending on the server configuration, load, and ambient temperature.
Corrosive gas pollutant
l
Corrosion rate of the copper test piece: less than 300 Å/
month (in compliance with the ANSI/ISA-71.04-2013 gas
corrosion level G1)
l
Corrosion rate of the silver test piece: less than 200 Å/
month
Particulate pollutant
l
The ISO14664-1 Class 8 requirements are met.
It is recommended that a professional company monitor
particulate pollutants in the equipment room.
