Dell™ PowerEdge™ 2450 computer systems are compact, high-speed servers that
offer significant service and upgrade features. These systems include the following
service features to make troubleshooting and repair easy and effective:


Dell Diagnostics, which checks for hardware problems (if the system can boot)


Embedded server management hardware, which monitors temperatures and
voltages throughout the system and notifies you if the system overheats, if a sys-
tem cooling fan malfunctions, or a power supply fails
The Dell PowerEdge 2450 system chassis simplifies removing and replacing com-
puter components. You can perform processor and memory upgrades without
removing the system board. The Dell-designed small computer system interface
(SCSI) backplane board and hard-disk drive carriers eliminate the extensive cabling
and drive configuration usually required for a SCSI subsystem.
The following upgrade options are offered for PowerEdge 2450 systems:


Additional microprocessors


Additional memory


An optional redundant power supply


An integrated redundant arrays of independent disks (RAID) controller that sup-
ports RAID levels 0, 1, 5, and 10


A SCSI backplane daughter card for split SCSI backplane support


A SCSI backplane extender board to support a fifth SCSI hard-disk drive in the
peripheral bay


A variety of expansion-card options


A Dell OpenManage™ Remote Assistant Card 2 (DRAC 2) for advanced server
management
