microprocessors. To take advantage of this feature, you must use an operating
® ®
system that supports multiprocessing, such as Microsoft Windows NT 4.0 or
®
Novell IntranetWare 4.11 (and later versions).
NOTE: If you decide to upgrade your system by installing a second micro-
processor, you must order the microprocessor upgrade kit from Dell. Not all
versions of the Pentium II microprocessor will work properly as additional
microprocessors. The upgrade kit from Dell contains the correct version of the
microprocessor for use as a second microprocessor, as well as instructions for
performing the upgrade. The second microprocessor must have the same inter-
nal operating frequency as the first.
A minimum of 64 megabytes (MB) of system memory, upgradable to a maximum
of 1 gigabyte (GB) by installing combinations of 64- and 128-MB unbuffered dual
in-line memory modules (DIMMs) or 256-MB registered synchronous dynamic
random-access memory (SDRAM) DIMMs in the four DIMM sockets on the sys-
tem board.
The unbuffered 72-bit-wide error checking and correction (ECC) SDRAM DIMMs
installed in PowerEdge 4300 systems support ECC to check for and correct mem-
ory errors. ECC is performed by the memory controller in the system chip set.
A basic input/output system (BIOS) that resides in flash memory on the Industry-
Standard Architecture (ISA) bus.
A hot-pluggable, six-slot small computer system interface (SCSI) backplane for up
to six 1.6-inch or 1-inch hard-disk drives.
Support for two additional 1-inch drives that can be installed in the external drive
bay. These additional drives are not hot-pluggable.
Two or three 320-watt (W) power supplies. Multiple power supplies require a
power-supply paralleling board (PSPB) and are hot-pluggable from the PSPB. A
single 320W power supply (when available) is attached with a cable harness.
NOTE: The standard system configuration of two power supplies is non-
redundant. To ensure redundancy, you must use three power supplies.
Five redundant system cooling fans.
The system board includes the following built-in features:
Six PCI and two ISA expansion-card connectors. PCI slots 1 through 4 are
unshared slots; PCI slot 5 is shared with ISA slot 5 and PCI slot 6 is shared with
ISA slot 6.
An advanced graphics port (AGP) video subsystem based on the ATI 3D Rage Pro
super video graphics array (SVGA) video controller. This video subsystem con-
tains 2 MB of synchronous graphics random-access memory (SGRAM) video
memory (nonupgradable). Maximum resolutions are 1024 x 768 with 256 colors
noninterlaced. In 800 x 600 and 640 x 480 resolutions, 16.7 million colors are
available for true-color graphics.
