System Overview
Dell
®
PowerEdge
®
6300 systems are feature-rich, enterprise-class server
systems that use Intel
®
Pentium
®
II Xeon
™
microprocessor(s) with MMX
™
technology and incorporate a high-performance PCI local bus.
The PowerEdge 6300 systems have been designed for better serviceability
and increased reliability. The sliding system board tray allows easy access to
the system board for performing processor and memory upgrades. The Dell-
designed SCSI backplane board and hard-disk drive carriers eliminate the
extensive cabling and drive configuration usually required for a SCSI sub-
system. The plastic drive rails attached to devices mounted in the external
drive bays allow you to remove these devices without removing a single
screw. The systems can be used either freestanding or rack-mounted.
A PowerEdge 6300 system can contain up to four Pentium II Xeon micropro-
cessors. Each processor is housed in a single-edge contact (SEC) cartridge/
heat sink assembly mounted in a guide bracket on the system board, allowing
for greater heat dissipation. The processor has an internal operating frequency
of 400 MHz (or a higher speed when available) and an external operating fre-
quency of 100 MHz. Contact Dell for information about Dell-supported
microprocessor upgrades.
System Features
In addition to the standard features found in a traditional personal computer,
Dell PowerEdge 6300 systems include the following new and/or advanced
features:
• One to four Intel Pentium II Xeon microprocessors with an internal operat-
ing frequency of 400 MHz (and higher speeds when available) and an
external bus speed of 100 MHz.
• Support for symmetric multiprocessing (SMP) when two or more micro-
processors are installed.
NOTE: Additional microprocessors must have the same internal operating
frequency as the initial microprocessors. Not all versions of the Pentium II
microprocessor will work properly as additional microprocessors in this
system; the upgrade kit from Dell contains the correct version for this
system.
• A secondary (L2) cache of 512 KB, 1 MB, or 2 MB of SRAM is included
within the SEC cartridge that contains the microprocessor.
