For more information, see theChassis Management Controller User’s Guide available at dell.com/support/manuals.To establish the serial connection:1. Configure the BIOS to enable serial connection.2. Connect the Null Modem DB9 cable from the management station’s serial port to the managed system’s external serialconnector.3. Make sure that the management station’s terminal emulation software is configured for serial connection using any of thefollowing:• Linux Minicom in an Xterm• Hilgraeve’s HyperTerminal Private Edition (version 6.3)Based on where the managed system is in its boot process, you can see either the POST screen or the operating systemscreen. This is based on the configuration: SAC for Windows and Linux text mode screens for Linux.4. Enable RAC serial or IPMI serial connections in iDRAC.Related linksConfiguring BIOS for serial connectionEnabling RAC serial connectionEnabling IPMI serial connection basic and terminal modesConfiguring BIOS for serial connectionTo configure BIOS for Serial Connection:110
