The Dell™ Remote Access Controller 5 (DRAC 5) 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 5 (when installed) can be configured to send you email alerts for warnings or errors related to voltages, temperatures, intrusion, and fan speeds. The DRAC 5 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.

The DRAC 5 has its own microprocessor and memory, and is powered by the system in which it is installed. The DRAC 5 may be preinstalled on your system, or available separately in a kit.

To get started with the DRAC 5, see "Installing and Setting Up the DRAC 5."

What's New in DRAC 5 in this Release?

For this release, DRAC 5 firmware version 1.20 supports the following:

• Standard Schema with Microsoft Active Directory® — Provides standard Active Directory objects for use in managing DRAC 5 users and user privileges. See "Standard Schema Active Directory Overview."
  
  
• Single Forest, Multiple Tree Support for Active Directory — Provides support for user authentication across multiple trees in a single forest in Microsoft Active Directory. See "Using DRAC 5 With Active Directory: Frequently Asked Questions."
  
  
• Disabling Local Video — Provides the capability to turn on or off the video output to a server's local monitor, which is useful when managing remote systems. See "Disabling or Enabling Local Video."
  
  
• Drive Letter Assignment in Virtual Media — Provides new functionality for Virtual Floppy drives. A Virtual Floppy drive is recognized as drive letter A: or B: by Windows operating systems and is enumerated as a floppy drive rather than a removable disk drive that takes drive letter C: or higher. See "cfgFloppyEmulation (Read/Write)."

Power Requirements

Table 1-1 lists the power requirements for the DRAC 5.

Table 1-1. DRAC 5 Power Requirements

Connectors

NOTE: The DRAC 5 hardware installation instructions can be found in the Installing a Remote Access Card document or the Installation and Troubleshooting Guide included with your system.

The DRAC 5 includes one onboard 10/100 Mbps RJ-45 NIC, a 50-pin management cable, and a 44-pin MII cable. See Figure 1-1 for the DRAC 5 cable connectors.

The 50-pin management cable is the main interface to the DRAC that provides connectivity to USB, serial, video, and an inter-integrated circuit (I2C) bus. The 44-pin MII cable connects the DRAC NIC to the system's motherboard. The RJ-45 connector connects the DRAC NIC to an out-of-band connection when the DRAC 5 is configured in Dedicated NIC mode.

Using the management and MII cables, you can configure your DRAC in three separate modes, depending on your needs. See "DRAC Modes" in "Using the RACADM Command Line Interface" for more information.

DRAC 5 Ports

Table 1-2 identifies the ports used by the DRAC 5 that listen for a server connection. Table 1-3 identifies the ports that the DRAC 5 uses as a client. This information is required when opening firewalls for remote access to a DRAC 5.

DRAC 5 Security Features

The DRAC 5 provides the following security features:

• User authentication through Microsoft Active Directory (optional) or hardware-stored user IDs and passwords
  
  
• Role-based authority, which enables an administrator to configure specific privileges for each user
  
  
• User ID and password configuration through the Web-based interface or RACADM CLI
  
  
• RACADM CLI and Web-based interface operation, which supports 128-bit SSL encryption and 40-bit SSL encryption (for countries where 128 bit is not acceptable)
  
  

NOTE: Telnet does not support SSL encryption.

• Session time-out configuration (in seconds) through the Web-based interface or RACADM CLI
  
  
• Configurable IP ports (where applicable)
  
  
• Secure Shell (SSH), which uses an encrypted transport layer for higher security.
  
  
• Login failure limits per IP address, with login blocking from the IP address when the limit is exceeded.
  
  
• Limited IP address range for clients connecting to the DRAC 5

Supported Web Browsers

NOTICE: Console Redirection and Virtual Media only supports 32-bit Web browsers. Using 64-bit Web browsers may generate unexpected results or failure of operations.

Table 1-6 lists the Web browsers that support the DRAC 5.

See the Dell OpenManage Server Administrator Compatibility Guide located on the Dell Support website at support.dell.com for the latest information.

Table 1-6. Supported Web Browsers

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 plugins for each distinct site that hosts the plugin. This process requires you to install a plugin for each distinct RAC IP/DNSname, even though the plugin versions are identical.

To disable the whitelist feature and avoid repetitive, unnecessary plugin installations, perform the following steps:

1. Open a Firefox Web browser window.
   
   
2. In the address field, type the following and press <Enter>:
   
   

about:config

3. In the Preference Name column, locate and double-click xpinstall.whitelist.required.
   
   

The values for Preference Name, Status, Type, and Value change to bold text. The Status value changes to user set and the Value value changes to false.

4. In the Preferences Name column, locate xpinstall.enabled.
   
   

Ensure that Value is true. If not, double-click xpinstall.enabled to set Value to true.
