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.

Operating temperature requirements
The heat dissipation performance of a server is also related to device power density in the rack, heat
dissipation capacity of the rack, and the spacing between the server and other devices.
