See “DIMMs” in Chapter 4 of this document for information on removing and
replacing DIMMs.
PCI Expansion Subsystem
The Resource Configuration Utility (RCU) included with the system automati-
cally configures installed PCI expansion cards. For more information on the
RCU, see Chapter 5, “Using the Resource Configuration Utility,” in the Dell
PowerEdge 6300 Systems User’s Guide.
The seven expansion-card slots include four 64-bit and three 32-bit PCI expan-
sion-card connectors located on the system board (see Figure 1-13). The 64-bit
slots support both 32- and 64-bit cards.
Video Controller
The video subsystem is built into the system board and consists of a PCI VGA-
compatible video subsystem with an ATI 3D RAGE PRO SVGA video controller.
The video subsystem contains 2 MB of SGRAM video memory, which is not
upgradable. Maximum noninterlaced resolutions are 640 x 480 (16.7 million
colors), 800 x 600 (16.7 million colors), and 1024 x 768 (256 colors).
Integrated SCSI Controllers
Two integrated Adaptec AIC-7890 Ultra2/LVD SCSI host adapters support up to
six 1- or 1.6-inch internal SCSI hard-disk drives through a 68-pin connector on
the system board for a SCSI backplane board. The SCSI backplane board auto-
matically configures SCSI ID numbers and SCSI termination on individual hard-
disk drives, greatly simplifying drive installation. The integrated SCSI controller
resides on the PCI local bus for optimum performance.
An integrated Adaptec AIC-7860 Ultra/Narrow SCSI host adapter attached to
the PCI bus supports up to three SCSI devices in the external drive bays
through a 50-pin connector on the system board.
SCSI Hard-Disk Drives
Dell PowerEdge 6300 systems include a SCSI backplane board, which greatly
simplifies cabling and configuration for SCSI hard-disk drives. SCSI ID and ter-
mination for SCSI hard-disk drives are both configured by the SCSI backplane
board, rather than on individual drives. SCSI hard-disk drives are supplied by
Dell in special drive carriers that fit in the internal drive bays.
NOTE: For maximum performance, install Ultra2/LVD drives exclusively.
Although you can install a mixture of Ultra2/LVD and Ultra hard-disk drives,
they will operate at the slower Ultra transfer rate.
