Power supplies
Compact tower models either come with a single fixed 350 W ac power supply or a single fixed 80 PLUS
Bronze 300 W ac power supply. There are no additional power supply options.
Standard tower models offer one or two hot-swap 430 W ac power supplies, which are 80 PLUS Silver
certified. For models with only one power supply, the part number to order a second power supply is listed
in the following table. Two power supplies that are installed form a redundant pair.

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.
