The system board can accommodate a single processor, five expansion cards, and four memory modules. The hard-drive cage provides space for up to four SAS or SATA hard drives. Two 5.25-inch external drive bays in the front of the system can accommodate optical or tape drives; a single 3.25 drive can accommodate an optional diskette drive. A controller expansion card is required to use SAS hard drives. Power is supplied to the system board and internal peripherals through a single, nonredundant power supply.


Opening the System

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the computer and protecting against electrostatic discharge.

Connecting Drives

Interface Cables

Most interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the cable connects to pin 1 in the connectors on both ends. When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.

Drive Cable Configurations

Your system can accommodate many different drive configurations, each with specific cable requirements. Table 3-1 shows the cable requirements for common drive configurations.

Your system can contain up to four 1-inch-height SATA or SAS hard drives in either a removable fixed hard-drive bay (see Figure 3-8) or a lever-release bay (see Figure 3-11). These drives connect either to the system board, an optional controller card, or an optional SAS backplane.

SAS or SATA drives can be hot-pluggable only if they are attached to an optional SAS backplane. See Hot-Plug SATA Hard Drives Using the SAS Backplane, Hot-Plug SATA Hard Drives Using the SAS Backplane, and Removing and Installing the Optional SAS Backplane Board.

Hard Drive Installation Guidelines

Use the following guidelines when installing hard drives:

Configuring the Boot Drive

The drive or device from which the system boots is determined by the boot order specified in the System Setup program (see Using the System Setup Program). To boot the system from a hard drive or drive array, the drive(s) must be connected to the appropriate controller:
