The server supports up to two redundant power supplies. Standard models come with one or two power supplies (model dependent). The server also comes standard with either two (for models with one processor installed) or three (for models with two processors installed) simple swap cooling fans. Optional upgrade is available to provide N+N cooling redundancy. The following table lists the power supplies and redundant cooling upgrade option.

Table 16. Power supplies

Certain rules apply to the selection of power supply, these rules are listed in Table 17. Table 17 uses the following conventions:

• A grey cell means that the server can be filled with drives, GPUs, processors and DIMMs up to the maximum number according to server specifications.
• A yellow cell means that the maximum number of drives, GPUs, processors or DIMMs that the server can hold is fewer than the total number listed in server specifications.

An AC power supply ships standard without a line cord, it must be purchased separately. The redundant cooling kit contains three simple swap fans
