The system board holds the system's control circuitry and other electronic components. Several hardware options, such as the microprocessors and memory, are installed directly on the system board. The expansion-card cage containing the left riser accommodates up to two full-length PCIe expansion cards, while the central riser accommodates one half-length PCIe expansion card.

The system provides space for an optical drive. The optical drive connects to the controllers on the system board through the sideplane board. For more information, see "Optical Drive and Cable" on page 96.

The hard-drive bays provide space for up to four 3.5-inch SATA hard drives. The hard drives connect to a SAS controller card through the SAS backplane board. For more information, see "Hard Drives" on page 68 and "SAS Controller Daughter Card" on page 85.

During an installation or troubleshooting procedure, you may be required to change a jumper setting. For more information, see "System Board Jumpers" on page 157.
