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
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."

if using a Windows operating system.
Disabling the Whitelist Feature in Mozilla Firefox
Firefox includes a "whitelist" feature that provides additional security. When
the whitelist feature is enabled, the browser requires user permission to install
plug-ins for each distinct site that hosts the plug-in. This process requires you
to install a plug-in for each distinct RAC IP/DNSname, even though the
plug-in versions are identical.
20 DRAC 4 Overview
To disable the whitelist feature and avoid repetitive, unnecessary plug-in
installations, perform the following steps:
1
Open a Firefox Web browser window.

Registering the DRAC Host Name With DNS Using DHCP
In DRAC 4 version 1.40 and later, you can configure your DHCP server to
dynamically register the DRAC DNS name in your DNS server database.
By enabling encryption in both the DHCP and DNS servers, the DRAC DNS
name can be registered in a secure environment.
To configure your DRAC to allow the DHCP server to update the DNS
database, set the cfgNicUseDhcp object value to 1 (TRUE) and
cfgDNSRegisterRac object value to 0 (FALSE). With this configuration,
the DRAC will supply cfgDNSRacName to the DHCP server.
See "cfgLanNetworking" for information about these object property settings.
NOTE: When you configure the DRAC, the DHCP server must also be configured to
perform the DNS database update.
Installing the Software on the Managed System
Installing software on the managed system is optional. Without the managed
system software, you lose the ability to use the racadm locally, and for the
RAC to capture the last crash screen.
To install the managed system software, install the software on the managed
system using the Dell Systems Management Tools and Documentation DVD.
For instructions about how to install this software, see your Software Quick
Installation Guide or Server Administrator User's Guide.
Installing and Setting Up the DRAC 4 27
Managed system software will install your choices from the following
components on the managed system: the appropriate version of Server
Administrator and the appropriate DRAC 4 agent or only the DRAC 4 agent.
NOTE: Do not install the DRAC 4 management station software and the DRAC 4
managed system software on the same system.
Depending on the operating system, the DRAC 4 agent consists of either
Microsoft Windows services, Novell NLMs, or Red Hat Enterprise Linux
agents. The DRAC 4 agent automatically starts when you boot the managed
system. If you install only the DRAC 4 agent, you will not have the ability to
view the system’s last crash screen or use the Watchdog feature. For more
information about the last crash screen, see "Viewing the Last System Crash
Screen." For more information about the Watchdog feature, see "System
Information."
Configuring the Managed System to Capture the Last Crash Screen
Before the DRAC 4 can capture the last crash screen, configure the managed
system with the following prerequisites.
