By default, your server supports onboard SATA software RAID levels 0, 1, and 10. However, you can
activate onboard SATA software RAID 5 by installing a ThinkServer SATA Software RAID 5 activation key in
the iButton socket. For more information, see “Installing or removing the ThinkServer RAID 100 upgrade
key for Advanced RAID” on page 111.

two front system fans.
10 Microprocessor
A microprocessor incorporates most or all of the functions of a computer's central processing unit (CPU) on
a single integrated circuit. The microprocessor for your server is secured in the microprocessor socket on
the system board and a heat sink and fan assembly is installed above the microprocessor to provide cooling.
For more information about your microprocessor type, see “Features” on page 7.
