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: Varies depending on the power consumed by the processors
and presence of expansion modules. For more information, see "
."
Storage temperature
–40°C to +70°C (–40°F to +158°F)
Operating humidity

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)

–60 m to +5000 m (–196.85 ft to +16404.20 ft)
Operating temperature requirements
General guidelines
The server supports N+1 fan redundancy. If a fan fails, server performance might degrade.
