Figure 5-1. Inside the System
The system board holds the system's control circuitry and other electronic components. Several hardware options such as the processor and memory are
installed directly on the system board. Using a riser board, the system can accommodate up to two expansion cards. The upper slot supports PCI 32-bit, 33-
MHz (5.0 V) expansion cards and the lower slot supports PCI-X 64-bit, 66-MHz (3.3 V) expansion cards.
The hard-drive bays provide space for up to two SATA or SCSI drives, an optional CD drive, and an optional diskette drive. The SCSI hard drives must be
connected to a controller card. Power is supplied to the system board, hard drives, and internal peripherals through a single nonredundant power supply.

The system is enclosed by an optional bezel and cover. To upgrade or troubleshoot the system, remove the bezel and cover to access the CD and diskette
drives, hard drives, power supply, and other internal system components.
