1-2 Dell PowerEdge 4300 Systems Service Manual
system; the upgrade kit from Dell contains the correct version for this
system.
A secondary (L2) cache of 512 KB of SRAM included within the SEC car-
tridge that contains the microprocessor.
64-MB and 128-MB (unbuffered) main memory, upgradable to 512 MB, or
upgradable to 1 GB using 256-MB registered SDRAM DIMMs.
BIOS in upgradable flash memory on the ISA bus.
Up to six hot-pluggable SCSI hard-disk drives. Two additional 1-inch drives
can be installed in the optional removable media bay.
Up to three redundant, hot-pluggable power supplies and a power-supply
paralleling board (PSPB), which is necessary for systems with two or more
power supplies.
Five redundant system cooling fans.
Six 32-bit PCI connectors and two shared 8-bit or 16-bit ISA connectors.
PCI and AGP local buses and ISA bus.
A VGA-compatible video subsystem with an ATI 3D Rage Pro AGP video
controller. This video subsystem contains 2 MB of SGRAM video memory
(nonupgradable).
A National Semiconductor PC87309 super I/O controller that controls the
bidirectional parallel port, two serial ports, and the diskette drive in the
externally accessible front bay.
An integrated Adaptec AIC-7890 Ultra2/LVD SCSI-3 host adapter that sup-
ports up to six 1.6-inch internal SCSI hard-disk drives via a SCSI backplane
board and special SCSI hard-disk drive carriers.
NOTE: The 1.6-inch drive carriers will accommodate 1-inch drives.
The SCSI backplane automatically configures SCSI ID numbers and SCSI
termination on individual hard-disk drives, greatly simplifying drive installa-
tion. The backplane supports hot-pluggable SCSI hard-disk drive installation
and removal when used in conjunction with a PowerEdge Expandable
RAID Controller.
An integrated Adaptec AIC-7860 Ultra/Narrow SCSI-3 host adapter that
supports the standard CD-ROM drive and two additional externally accessi-
ble SCSI devices in the external hard-disk drive bays.
Drive failure, online, and activity indicators visible on each hard-disk drive
connected to the SCSI backplane.
Server management circuitry that monitors operation of the system fans
as well as critical system voltages and temperatures. The server manage-
ment circuitry works in conjunction with the HP OpenView Network Node
Manager Special Edition (NNM SE) and the Dell OpenManage™ Hardware
Instrumentation Package (HIP).
System board support for the Dell OpenManage Remote Assistant when
the optional Dell Remote Assistant Card version 2 (DRAC 2), which pro-
vides additional local and remote server management, is installed.
