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 Featu re s" ).

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.

Supported Web Browsers for 64-Bit Operating Systems

If your system is running a supported 64-bit operating system (see Table 1-4), install and run a supported 32-bit Web browser (see Table 1-5). Otherwise, you may experience unexpected results when running Virtual Media and other processes.

If your system is running a supported 64-bit version of Windows, the supported 32-bit version of Internet Explorer is installed by default.

If your system is running a supported 64-bit version of Red Hat Enterprise Linux, install the supported version of Mozilla or Mozilla Firefox. These Web browsers are located on your operating system CDs that are included with your system and on the Mozilla website located at www.mozilla.org/download.html.

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.

DRAC 4 Overview 23

To disable the whitelist feature and avoid repetitive, unnecessary plug-in installations, perform the following steps:

Open a Firefox Web browser window.

Dell Systems Documentation

Installing the DRAC 4 Hardware

NOTE: The DRAC 4 connection emulates a USB keyboard connection. As a result,

when you restart the system, the system will not notify you if your keyboard is not attached.

The DRAC 4 may be preinstalled on your system, or available separately in a kit. To get started with the DRAC 4 that is already installed on your system, see "Software Installation and Configuration Overview."

If a DRAC 4 is not installed on your system, see the Installing a Remote Access

Card

document that came with your DRAC 4 kit or see your platform

Installation and Troubleshooting Guide for hardware installation instructions before proceeding.

NOTE: Removing expansion cards, such as the DRAC 4, is documented in the

Installation and Troubleshooting Guide that is included with your system.

Installing and Setting Up the DRAC 4 27

Software Installation and Configuration Overview

This section provides a high-level overview of the DRAC 4 software installation and configuration process. Configure your DRAC 4 using the Web-based interface, racadm CLI, or Serial/Telnet console. Network configuration can also be performed using operating system utilities (Option ROM).

For more information about the DRAC 4 software components, see "Installing the Software on the Managed System."

NOTE: For basic information about using the Red Hat Enterprise Linux operating

system, see "DRAC 4 Software Basics for Red Hat Enterprise Linux."

Installing Your DRAC 4 Software

To install your DRAC 4 software, perform the following steps in order:

Update the system BIOS.

Install the software on the managed system. See "Installing the Software on the Managed System."

Install the software on the management station. See "Installing the Software on the Management Station."

Configuring Your DRAC 4 Software

To configure your DRAC 4 software, perform the following steps in order:

Select one of the following configuration tools:

NOTICE: Using more than one configuration tool at the same time may

generate unexpected results.

• Web-based interface

•racadm CLI

• Serial/Telnet console

• Operating system utilities (Option ROM)

Configure the DRAC 4 network settings. See "Configuring the DRAC 4 Network Settings."

Add and configure DRAC 4 users. See "Adding and Configuring DRAC 4 Users."

28 Installing and Setting Up the DRAC 4

Configure the Web browser to connect to the Web-based interface. See "Configuring a Supported Web Browser."

Install the Sun Java plug-in. See "Installing the Sun Java Plug-In."

NOTE: The Sun Java plug-in is only required if you are using the Console

Redirection feature.

Disable the Windows Automatic Reboot Option. See "Disabling the Windows Automatic Reboot Option."

Update the DRAC 4 Firmware. See "Updating the DRAC 4 Firmware."

Access the DRAC 4 through a network. See "Accessing the DRAC 4 Through a Network."

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 Console and Agent CD. For instructions about how to install this software, see your Quick Installation Guide or Server Administrator User's Guide.

Installing and Setting Up the DRAC 4 29

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.

Install the managed system software. For more information about installing the managed system software, see the
