Communicating with iDRAC through serial connection using DB99 cable

You can use any of the following communication methods to perform systems management tasks through serial connection to rack and tower servers:
  • RAC Serial
  • IPMI Serial — Direct Connect Basic mode and Direct Connect Terminal mode
  • NOTE: In case of blade servers, the serial connection is established through the chassis. For more information, see the Chassis 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 serial connector.
  3. Make sure that the management station’s terminal emulation software is configured for serial connection using any of the following:
    • 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 system screen. 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.
