Dell Remote Access Controller 4 Firmware Version 1.60 User's Guide
This chapter provides information about how to install and setup your DRAC 4 hardware and software.
Gather the following items that came with your system prior to installing and configuring the DRAC 4 software.
|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.|
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."|
To install your DRAC 4 software, perform the following steps in order:
To configure your DRAC 4 software, perform the following steps in order:
|NOTICE: Using more than one configuration tool at the same time may generate unexpected results.|
|NOTE: The Sun Java plug-in is only required if you are using the Console Redirection feature.|
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 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.
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."
Before the DRAC 4 can capture the last crash screen, configure the managed system with the following prerequisites.
The last crash screen is not available when the Watchdog recovery action is set to Shutdown or Power Cycle if the managed system is powered off.
To ensure that the DRAC 4 Web-based interface last crash screen feature works properly, disable the Automatic Reboot option on managed systems running the Microsoft Windows Server 2003 and Windows 2000 Server operating systems.
Your system includes the Dell OpenManage System Management Software Kit. This kit includes, but is not limited to, the following components:
|NOTE: Starting with Dell OpenManage version 5.3, you can also obtain all the above components from the Dell Systems Management Tools and Documentation DVD and the Dell Server Updates DVD.|
For instructions about installing Server Administrator software, see your Server Administrator User's Guide.
You must install the racadm CLI on a management station running Red Hat Enterprise Linux so that the remote racadm functions can be used.
|NOTE: The racadm CLI utility is installed automatically for all other supported operating systems when you install the Dell Systems Console and Agent CD.|
To install the racadm CLI utility, insert the Dell Systems Console and Agent CD in the management station's CD drive and type the following commands from a command prompt:
rpm -ivh linux/rac/*.rpm
For help with the racadm command, type the man racadm or racadm help command after issuing the previous commands. For more information about the racadm CLI, see "Using the Serial and racadm Commands."
You can uninstall the racadm CLI by issuing the following command from a command prompt:
- rpm -e racadm
The following sections provide instructions for configuring the supported Web browsers. For a list of supported Web browsers, see "Supported Web Browsers."
If you are connecting to the DRAC 4 Web-based interface from a management station that connects to the Internet through a proxy server, you must configure the Web browser to access the Internet from this server.
To configure your Internet Explorer Web browser to access a proxy server, perform the following steps:
To configure your Firefox Web browser to access a proxy server, perform the following steps:
The DRAC 4 Web-based interface is supported on the following Windows operating system languages:
To view a localized version of the DRAC 4 Web-based interface in Internet Explorer, perform the following steps:
To select more than one language, press <Ctrl>.
All browsers must have the supported Sun Java plug-in 1.4.2 or later installed to use the DRAC 4 Console Redirection feature.
Prior to using Console Redirection on Windows systems, install the supported Sun Java plug-in and clear and disable the Java cache from the Java plug-in control panel.
To install the Sun java plug-in, go to http:\\java.sun.com, download JRE 1.4.2 or later, and follow the instructions on screen.
To clear the Java cache on a Windows operating system, perform the following steps:
|NOTE: For a list of the latest supported Java Virtual Machine (JVM) plug-ins, see the racread.txt file located on the Dell Systems Console and Agent CD or at the Dell Support website at support.dell.com.|
You must install the Java plug-in 1.4.2 or later to use the DRAC 4 Virtual KVM feature with the Mozilla Web browser. To install the Java plug-in, perform the following steps:
chmod a+x j2re-1_4_<version number>-linux-i586-rpm.bin
The script displays a binary license agreement, and prompts you to accept before continuing the installation.
After you accept the license agreement, the installation script creates the following file in the current directory:
At the command prompt, type:
At the command prompt, type:
rpm -iv j2re-1_4<version number>-linux-i586.rpm
The Java plug-in packages are installed on your system.
|NOTE: Only one Java plug-in can be registered at a time. If you have never registered a Java plug-in, go to step 5. Otherwise, follow the procedure in this step.|
Most Mozilla installations use symbolic links to where the Java plug-in is located. The name of the symbolic link is libjavaplugin_oji.so, which is in the /plugins subdirectory of Mozilla.
To delete the symbolic link, type:
cd /usr/lib/mozilla<version number>/plugins
Locate the libjavaplugin_oji.so file in the j2re1.4<version number> directory. Usually, it is located in the /i386/ns600 or /i386/ns610 subdirectory.
Use the create a symbolic link feature in Mozilla that points to the libjavaplugin_oji.so file in the /i386/ns610 subdirectory.
At the command prompt, type:
ln s j2re1.4<version number>/plugin/i386/ns610/libjavaplugin_oji.so libjavaplugin_oji.so
|NOTE: Create the link using the /plugins subdirectory of Mozilla. You cannot create the link from the <JRE> directory.|
The JRE version is displayed at the top of the Java Console window.
If the version that is shown is not the same as the version you downloaded or if the Java Console menu option is grayed out, the software is not registered.
You can configure all of the DRAC 4 properties (network, users, alerts, etc.) using the Web-based interface, or racadm CLI.
For more information about how to use the Web-based interface, see "Accessing the Web-Based Interface." For more information about how to use the racadm CLI through a serial or telnet see "Using the Serial and racadm Commands."
