Figure 5-1. Inside the System
The system board contains 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 system accommodates up to six expansion cards (one PCI Express [PCIe] x8-lane slot, one
PCIe x4-lane slot, two PCI-X 64-bit/100-MHz slots, one PCI 64-bit/66-MHz slot, and one PCI
32-bit/33-MHz 5V slot). System memory is contained in six memory module sockets.
NOTE:
Although the PCIe x4-lane expansion slot is physically a PCIe x8 connector, it functions only as a
PCIe x4-lane slot.
The system supports a 3.5-inch diskette drive and up to two externally accessible 5.25-inch drives,
such as CD, data-only DVD, or half-height tape drives. The hard-drive bays support the following
hard drive configurations:
• Up to two non–hot-plug SATA hard drives when the hard drives are connected to the system
