Introduction
Dell™ PowerEdge™ 2550 Systems Installation and Troubleshooting Guide
Dell™ PowerEdge™ 2550 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:
l Dell Diagnostics, which checks for hardware problems (if the system can boot)
l Embedded server management hardware, which monitors temperatures and voltages throughout the system and notifies you if the system overheats,
a system cooling fan malfunctions, or a power supply fails
The chassis simplifies removing and replacing system components. 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 your PowerEdge system:
l An additional microprocessor
l Additional memory
l An optional redundant power supply
l An integrated redundant array of independent disks (RAID) controller that supports RAID levels 0, 1, 5, and 10
l An optional SCSI backplane daughter card for split SCSI backplane support
l A SCSI backplane extender board to support a fifth SCSI hard-disk drive in the peripheral bay
l A variety of expansion-card options
l A Dell OpenManage™ Remote Assistant Card for system management
