System fans

Your server supports up to six hot-swap system fans. This design helps you avoid significant cooling
problems when a system fan fails. You can replace a system fan without turning off the server. To locate the
system fans, see “System board components” on page 43.

• If your server is installed with one microprocessor, four system fans (fan 1 to fan 4) are adequate to

provide proper cooling. However, you must keep the locations for fan 5 and fan 6 occupied by dummy
fans to ensure proper airflow.

• If your server is installed with two microprocessors, ensure that all the six system fans are installed to

avoid cooling problems.

Internal drives

Internal drives are devices that your server uses to read and store data. The internal drives supported
