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 (two 64-bit/100-MHz PCI-X cards, two 64-bit/66-MHz PCI cards, and two 32-bit/33-MHz PCI cards).
System memory is contained in four memory module sockets.
The system supports a 3.5-inch diskette drive and up to two externally accessible 5.25-inch drives, such as CD, DVD, or tape drives. The hard-drive bays
support up to four IDE hard drives or four non-hot-plug SCSI hard drives or up to six hot-plug SCSI hard drives. The hard drives connect to a controller on the
system board or to a controller card.
During an installation or troubleshooting procedure, you may be required to change a jumper setting. For more information, see "

Connectors

Responding to a Systems Management Alert Message
The optional systems management applications monitor critical system voltages and temperatures, the cooling fans, and the status of hard drives in the
system. Alert messages appear in the alert log window. For information about the alert log window and options, see your systems management software
documentation.

NOTICE:
Dell strongly urges you to install the systems management applications to receive alerts if a hardware problem occurs. For example, if a
redundant power supply fails, you receive no notification that the system is operating in a nonredundant power mode unless you have installed the
systems management applications.
