About environment requirements
The operating temperature requirements for the server vary depending on the server model and
hardware configuration. When the general and component-based requirements conflict, use the
component-based requirement.
Be aware that the actual maximum operating temperature of the server might be lower than what is
stated because of poor site cooling performance. In a real data center, the server cooling
performance might decrease because of adverse external factors, including poor cabinet cooling
performance, high power density inside the cabinet, or insufficient spacing between devices.
General environment requirements
Item Specifications
Operating temperature
Minimum: 5°C (41°F)
Maximum:
•
For 32SFF and 48SFF drive configurations: 40°C (104°F)
•
For 16SFF drive configuration: 45°C (113°F)
CAUTION:
The maximum temperature varies by hardware option presence. For more
information, see "
Operating temperature requirements
Storage temperature
–40°C to +70°C (–40°F to +158°F)
Operating humidity
8% to 90%, noncondensing
Storage humidity
5% to 95%, noncondensing
Operating altitude
–60 m to +3000 m (–196.85 ft to +9842.52 ft)
The allowed maximum temperature decreases by 0.33 °C (32.59°F) as the
altitude increases by 100 m (328.08 ft) from 900 m (2952.76 ft)
Storage altitude
–60 m to +5000 m (–196.85 ft to +16404.20 ft)
Operating temperature requirements
Use
to determine the maximum operating temperature of the servers with
8 SFF drives in each compute module or 24 SFF drives in either compute module. A maximum
server operating temperature applies if the server contains any options in its matching hardware
option list.
NOTE:
All maximum server operating temperature values are provided on the basis that the fan modules
are installed as needed and operating correctly. For more information about fan modules, see "
