Fans and cooling
Both the compact tower design (with a single fixed power supply) and the standard tower design (with
hot-swap power supplies) come with one or two speed-controlled non-redundant fans, model dependent
(see Table 2). The second fan is required if two or more adapters are installed, and the fan is configured
by selecting the appropriate Thermal Solution Fan Kit, as listed in the following table.
If you want to operate the server in an environment up to 40°C (104°F), use the optional Operating
Temperature Enhancement Kit that is listed in the table. This kit contains an additional thermal sensor.
