DRAC 4 Overview
The Dell™ Remote Access Controller 4 (DRAC 4) is a systems management hardware and
software solution designed to provide remote management capabilities, crashed system recovery,
and power control functions for Dell PowerEdge™ systems.
By communicating with the system’s baseboard management controller (BMC), the DRAC 4
can be configured to send you email alerts for warnings or errors related to voltages,
temperatures, and fan speeds. The DRAC 4 also logs event data and the most recent crash
screen (for systems running the Microsoft
®
Windows
®
operating system only) to help you
diagnose the probable cause of a system crash.
Depending on your system, the DRAC 4 hardware is either a daughter card (DRAC 4/I) or a
half-length PCI card (DRAC 4/P). The DRAC 4/I and DRAC 4/P are identical except for the
hardware differences (see "
DRAC 4 Hardware Features").
The DRAC 4 has its own microprocessor and memory, and is powered by the system in which it
is installed. The DRAC 4 may be preinstalled on your system, or available separately in a kit.
To get started with the DRAC 4, see "Installing and Setting Up the DRAC 4."
