microprocessors. The upgrade kit from Dell contains the correct version of the
microprocessor for use as an additional microprocessor, as well as instructions
for performing the upgrade. The additional microprocessors must have the same
internal operating frequency and cache size as the initial microprocessors.
A minimum of 128 MB of system memory, upgradable to a maximum of
4 gigabytes (GB) by installing combinations of 32-, 128-, and 256-MB buffered
extended-data out (EDO) dual in-line memory modules (DIMMs) in the 16 DIMM
sockets on the memory board.
A basic input/output system (BIOS) that resides in flash memory on the Periph-
eral Component Interconnect (PCI) bus and can be upgraded if required.
Up to three, hot-pluggable, 1-inch, small computer system interface (SCSI) hard-
disk drives.
Three redundant, hot-pluggable power supplies and a power-supply paralleling
board (PSPB).
NOTE: A minimum of two power supplies are needed to run the system.
Four redundant system cooling fans.
The system board includes the following built-in features:
Seven PCI connectors — four 64-bit and three 32-bit.
A video graphics array (VGA)-compatible video subsystem with an ATI 3D Rage
Pro super VGA (SVGA) video controller. This video subsystem contains 2 MB of
synchronous graphics random-access memory (SGRAM) video memory (nonup-
gradable). Maximum resolutions are 1280 x 1024 with 256 colors, noninterlaced.
The 1024 x 768 resolution provides 65,536 colors, noninterlaced, and the
800 x 600 and 640 x 480 resolutions provide 16.7 million colors for true color
graphics.
A National Semiconductor PC87309 super input/output (I/O) controller that con-
trols the bidirectional parallel port, two serial ports, and the diskette drive in the
externally accessible front bay.
The parallel port can be set to operate in the following modes via the Parallel
Mode category in the System Setup program: output-only (AT-compatible) or
bidirectional (Personal System/2 [PS/2]-compatible).
Two Adaptec AIC-7890 Ultra2/low voltage differential (LVD) SCSI host adapters
that support up to three, 1-inch, internal SCSI hard-disk drives via a SCSI back-
plane board and SCSI hard-disk drive carriers. The SCSI backplane automatically
configures SCSI ID numbers and SCSI termination on individual hard-disk drives,
greatly simplifying drive installation.
A hot-pluggable 1 x 3 SCSI backplane board supports hot-pluggable SCSI hard-
disk drive installation and removal when used in conjunction with the PowerEdge
Expandable RAID Controller products.
An Adaptec AIC-7860 Ultra/Narrow SCSI-III host adapter that supports the
CD-ROM drive.
