In Figure 5-4, the covers and bezel are removed to provide an interior view of the system.
Figure 5-4. Inside the System
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 system board can accommodate up to seven PCI expansion cards (two PCI or PCI-X cards at 64-bit/33-133 MHz, four PCI or PCI-X cards at 64-bit/33-100 MHz, and one PCI card at 32-bit/33 MHz).
The peripheral bay provides space for a 3.5-inch diskette drive, a CD drive, and two other devices (two hard drives or one tape drive).
The hard-drive bays provide space for up to six 1-inch hard drives. These hard drives are connected to a SCSI host adapter on the system board or on an expansion card, by way of the SCSI backplane board.
The power distribution board (PDB) provides power distribution for the system. One front-loadable power supply slides into connectors mounted on the PDB to provide power to the system board and internal peripherals. An option for a second hot-pluggable power supply to provide redundant power is available.
For non-SCSI drives such as the diskette drive and CD drive, an interface cable connects the interposer board, attached to the diskette drive and CD drive, to the system board. For SCSI devices, interface cables connect externally accessible SCSI devices and the SCSI backplane board to a SCSI host adapter either on the system board or on an expansion card. For more information, see "Installing Drives."
During an installation or troubleshooting procedure, you may be required to change a jumper. For information on the system board jumpers, see "Jumpers and Connectors."
The optional systems management software monitors critical system voltages and temperatures, the system cooling fans, and the status of the hard drives in the system. Alert messages appear in the alert log window. For information about the alert log window and options, see the systems management software documentation.

- Remove the hard drive and install it in the another drive bay.
- If the problem is resolved, reinstall the hard drive in the original bay.
If the hard drive functions properly in the original bay, the drive carrier could have intermittent problems. Ensure that the drive is properly mounted on the drive carrier (see "Removing a Hard Drive" in "Installing Drives").
If the drive carrier still does not function properly in the original bay, the SCSI backplane board has a defective connector. See "Getting Help" for instructions on obtaining technical assistance.
- If a RAID controller card is installed, check the SCSI cable connections inside the
system:
- Turn off the system, including any attached peripherals, and disconnect the
system from its electrical outlet.
- Open the bezel (see "Removing the Bezel").
- Remove the cover (see "Removing the Cover").
- Check the SCSI cable connection to the RAID controller card (see the RAID
controller's documentation for detailed information).
|
NOTE: To operate the SCSI backplane in a 1 x 6 configuration, ensure that the SCSI
backplane daughter card is not installed. To operate the SCSI backplane in a 2 x 3 split
configuration, ensure that the SCSI backplane daughter card is installed (see "Installing a
SCSI Backplane Daughter Card" in "Installing Drives").
