1. When the second microprocessor is populated, the fan is included in the second
microprocessor kit, P/N: 00D2581 ~ 00D2589. Or
2. When more than 2 PCI-e adapters have been installed on the system, the fan (P/N:
00D2593) will be available separately.

Optional redundant fan (P/N: 00D2593)
Attention: When fan 3 is installed and 16 GB 1.5V / 32 GB 1.35V DIMMs are installed, fan
1 must also be populated.
• The server system board supports a minimum of 2 GB and a maximum of 96 GB of system memory.
Note: The amount of usable memory is reduced depending on the system configuration. A certain
amount of memory must be reserved for system resources. To view the total amount of installed memory
and the amount of configured memory, run the Setup utility. For additional information, see "Configuring
the server" on page 92.
• The server system board provides three memory channels for each microprocessor and each memory
channel supports up to two DIMMs. The following table lists the DIMM connectors on each memory
channel:

• The maximum operating speed of the server is determined by the slowest DIMM installed in the server.
• A minimum of one DIMM must be installed for each microprocessor. For example, you must install a
minimum of two DIMMs if the server has two microprocessors installed. That is, one for microprocessor 1
and one for microprocessor 2.
• The server comes with a minimum of one DIMM installed in slot 1. When you install additional DIMMs,
install them in the order shown in the information in the following tables to optimize system performance.
• The server supports independent mode, spare channel mode, and mirroring mode.
• Independent mode: When you use the independent mode, install DIMMs as indicated in the following
tables.
