Environment requirements

Operating temperature requirements

 

NOTE:

The cooling capability of the server depends on the power density of devices within the cabinet, the cooling capability of the cabinet, and the spacing between the server and other devices. When the server is stacked with other devices, the maximum operating temperature of the server might decrease.

 

For the server-compatible components and detailed information, visit the component compatibility lookup tool at http://www.h3c.com/en/home/qr/default.htm?id=66.

Table 1 shows the operating temperature specifications of the server.
